Description

A soft metal sleeve insertion rod

technical field

The invention relates to a tooling device, in particular to a soft metal sleeve insertion rod.

Background technique

In the fields of chemical industry, machinery, electronics, toys, and military production, a common process is to embed a tapered hard metal rod into a soft metal sleeve, and the soft metal sleeve on the tapered hard metal rod meets the technical requirements. And complete the above-mentioned operations over and over again. The soft metals include metals such as lead, copper, and aluminum, and the hard metals refer to metals with certain elasticity without heat treatment. At present, the technological process adopted includes the following steps: 1. Evenly drill a number of jacks (product holes) on the surface of the flat turntable, the diameter of which is about larger than the diameter of the soft metal casing; 2. Slowly rotate the turntable, and several operators separately Insert the soft metal sleeve into the socket of the turntable; some operators embed the conical hard metal rod into the soft metal sleeve (the length of the tapered hard metal rod is longer than the soft metal sleeve), and the soft metal sleeve should be used according to the technical requirements. Insert it into the middle of the tapered hard metal rod; 3. Use the mechanical arm to press the tapered hard metal rod into place (press into the technical requirements of the soft metal sleeve and the tapered hard metal rod); 4. Use a mechanical arm This assembly is punched out in reverse to complete a working cycle. The problem that existing process technology exists is:

There are more than 2 operators for inserting the soft metal sleeve surrounding the turntable. The operators are prone to fatigue during the operation, and the work efficiency decreases with time. The inserting operation is prone to produce defects of varying degrees, which affects production efficiency and product quality.

Contents of the invention

Aiming at the problems existing in the prior art, the technical problem to be solved by the present invention is to provide a soft metal casing insertion rod, which can realize the machine insertion of the soft metal casing, reduce labor, control the size of the insertion, and reduce the Quality defects or malfunctions in the loading operation.

The technical problem to be solved by the present invention is achieved through such a technical scheme, which includes a through sleeve rod, an outer sleeve, a buffer inner spring, a push plug, a slowing mechanism and a limit pin. The inside of the outer sleeve is a stepped through hole, and the outer sleeve Set on the outer layer of the through-sleeve rod, the middle part of the through-sleeve rod in the large-diameter hole of the outer sleeve is equipped with a plug, and a buffer inner spring set on the through-sleeve rod is embedded between the plug and the inner step surface of the outer sleeve, and the right rear of the outer sleeve There is a limit pin at the top, and a chute to match the limit pin is opened on the sleeve rod. There is a back-stop nest above the middle of the outer casing, and a slow-stop mechanism is installed right above the back-stop nest.

The present invention uses the front part of the through rod to cover the soft metal sleeve in series, and pushes the soft metal sleeve into the product hole of the turntable, and then uses the outer sleeve to block the soft metal sleeve, preventing the through rod from exiting the product hole and bringing out the soft metal sleeve. Metal casing ensures reliable insertion. The technical effect of the invention is that the soft metal casing can be inserted by machine instead of manual, and the insertion is reliable, reducing the quality defect or failure caused by manual process.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

In order to clearly describe the content of the invention, this patent application uses the orientation words "up", "down", "left" and "right" to distinguish, and the "up", "down", "left" and "right" are based on the above The layout orientation of the accompanying drawings is determined. When the actual use direction of the present invention changes, the appellation of the orientation will change accordingly, which cannot be regarded as limiting the scope of patent protection.

As shown in Figure 1, the present invention includes a through sleeve rod 1, an outer sleeve 2, a buffer inner spring 3, a push plug 4, a slowing mechanism 5 and a limit pin 7, the inside of the outer sleeve 2 is a stepped through hole, and the outer sleeve 2 sets On the outer layer of the sleeve rod 1, the middle part of the sleeve rod 1 in the large-diameter hole of the outer sleeve 2 is equipped with a plug 4, and a buffer inner sleeve on the sleeve rod is embedded between the plug 4 and the inner step surface of the outer sleeve 2. The spring 3, the right rear part of the outer casing 2 is provided with a limit pin 7, and the through sleeve rod 1 is provided with a chute 71 that cooperates with the limit pin 7, and the limit pin 7 and the chute 71 are combined to keep the outer sleeve and the through sleeve The rod has a hysteresis linkage, and an anti-retreat nest 21 is provided above the middle part of the outer sleeve 2, and a slow-stop mechanism 5 is installed just above the anti-retreat nest 21.

The left end of the through sleeve rod 1 is a conical body, which is conducive to the soft metal sleeves in series and inserted into the product hole; the right port of the outer casing 2 is equipped with a guide ring plug 6, which is used for the sliding guide of the through sleeve rod 1.

The retarding mechanism 5 includes a tube with a chassis, the tube is equipped with a compression spring, the lower end of the spring is fixed with a taper pin, the taper pin protrudes from the lower port of the tube, and the taper pin falls into the outer casing anti-retraction nest 21 to realize the outer casing Suspended retreat, the chassis of the tube is used for fixed installation on the base plate.

The use process of the present invention is:

As shown in Figure 2, a product hole 81 is opened on the upright turntable 8, and a conveyor 10 is installed near the front of the turntable. The transmission channel, the soft metal sleeve 9 is sequentially transmitted from the transmission channel to the through hole of the conveyor. The insertion rod 12 of the present invention is located on the outside of the through hole of the conveyor 10, and is installed parallel to the coaxial line of the through hole. The front end of the insertion rod 12 of the present invention is provided with a guide seat 11.

The turntable 8 rotates one step, corresponding to a product hole 81 in place, the machine tool slide plate pushes the sleeve rod 1 of the present invention to extend forward into the through hole of the conveyor 10, strings the soft metal sleeve 9 in the through hole, and puts the string sleeve The soft metal sleeve and the front part of the sleeve rod 1 are pushed into the product hole 81 of the turntable; at the same time, the outer sleeve 2 is buffered and pushed under the drive of the buffer inner spring 3, and the outer sleeve 2 passes through the conveyor 10. The hole is against the disc surface of the turntable and blocks the product orifice. Next, the through sleeve rod 1 withdraws from the product hole 81 due to the return of the machine tool slide, the outer casing 2 temporarily does not move under the action of the slow stop mechanism 5, and the soft metal sleeve 9 is blocked in the turntable product hole 81 to avoid withdrawing from the through sleeve rod 1 Bring out the soft metal sleeve. Later, the limit pin 7 of the outer sleeve 2 slides to the left end of the chute 71 of the through sleeve rod 1, the through sleeve rod 1 drags the outer sleeve 2, and the pin cone of the slow stop mechanism 5 withdraws from the outer sleeve stop nest 21, The outer casing 2 retreats together with the through-sleeve rod 1 until it returns to the initial position, completing a soft metal casing insertion.

The turntable rotates three steps clockwise, the product hole 81 leaves the conveyor 10, and then the hard metal rod is embedded in the soft metal tube and pressed into place, and the turntable rotates to the fifth step to complete the reverse ejection of the product.
