Description

Adapter block structure of universal joint and universal joint

The present invention relates to universal joints, and in particular, to a transfer block structure of a universal joint and a universal joint.

Referring to the US Patent No. 6656053, the universal joint includes a first base body for connecting and driving a driving tool, a second base body for connecting and driving a workpiece, and a universal joint between the first base body and the second base body. and an adapter block for transmitting torque, a first bolt inserted between the first base body and the adapter block, a second bolt inserted between the second base body and the adapter block, And a reset piece is provided between the first base body and the adapter block and between the second base body and the adapter block, so that the two opposite members have a pre-force for reset, and the reset piece is hidden in the two members. time, the universal joint can rotate in all directions when it is subjected to external force, and when the external force is eliminated, its reset component can directly achieve a rapid reset effect. However, it still has the following shortcomings:

First, it is difficult to process. Refer to Figure 1, which shows one of the drawings of the US patent case US6656053. Since the two ends 111 and 112 of the reset member 11 must be inserted and positioned in the first base 12 (or the second base) and the adapter block 13 respectively, in addition to the first base 12 (or the second base) In addition to a slot 121 that must be processed on the base), a slot 131 must also be processed on the adapter block 13. However, the slot 131 on the adapter block 13 and the groove wall 132A of the accommodating groove 132 are too large. During the drilling process, the processing drill bit (not shown in the figure) must pass through the groove wall 132A of the accommodating groove 132, so that the processing drill bit is easily damaged or the adapter block is damaged during the drilling process. 13 structure, highlighting the disadvantage of difficult processing.

Second, the strength is insufficient. Referring also to Figure 1, since the adapter block 13 must be formed with a through hole 133 for the first latch 14 and the second latch 15 to pass through, a slot 131 is processed for the one end 111 of the reset member 11 to be inserted. At the same time, drilling interference is avoided. Therefore, the position of the slot 131 must be closer to the through hole 133. This also causes the thickness between the slot 131 and the through hole 133 to be too thin, thus affecting the structure of the adapter block 13. intensity.

The purpose of the present invention is to provide an adapter block structure of a universal joint and a universal joint, which mainly improves the convenience of processing.

The above is the configuration description of each main component of the embodiment of the present invention. As for the effect of the present invention, the following is a description:

First, improve processing convenience. Since the first jack hole 281 and the second jack hole 282 of the adapter block 20 of the present invention are processed from the first end face 211 toward the second end face 212, and the third jack hole 283 and the fourth jack hole 283 of the adapter block 20 The jack holes 284 are formed from the second end face 212 toward the first end face 211. Therefore, each jack hole will not be affected by other structures of the adapter block 20 during the processing. Therefore, each jack hole is During the processing, other structures of the adapter block will not be damaged, thereby improving processing convenience.

Second, improve the structural strength. Likewise, because the first socket 281 and the second socket 282 are formed from the first end surface 211 toward the second end surface 212 , and the third socket 283 and the fourth socket The hole 284 is formed from the second end surface 212 toward the first end surface 211. Therefore, the processing position of each socket can be relatively far away from each side surface, so that there is a certain distance between the forming position of each socket and each side surface. It is formed with a certain thickness to achieve the purpose of improving the structural strength.

It is worth noting that the forming position of the first socket 281 of the adapter block 20 is not limited to adjoining the first groove bottom surface 221. It is located between the first side surface 213 and the first groove bottom surface 221 as structural strength permits. Either way, of course, the closer the first socket 281 is to the first slot bottom surface 221 and the further away from the first side surface 213, the stronger the structural strength will be. Similarly, the forming position of the second socket 282 of the adapter block 20 is not limited to adjoining the second groove bottom surface 231. It can be between the second side surface 214 and the second groove bottom surface 231 as the structural strength permits. Of course, the closer the second insertion hole 282 is to the second groove bottom surface 231, the further away from the second side surface 214, and the stronger the structural strength is. Similarly, the forming position of the third socket 283 of the adapter block 20 is not limited to adjoining the third groove bottom surface 251. It can be between the third side surface 215 and the third groove bottom surface 251 as the structural strength permits. Of course, the closer the third socket 283 is to the third slot bottom surface 251, the farther it is from the third side surface 215, and the stronger the structural strength is. Similarly, the forming position of the fourth socket 284 of the adapter block 20 is not limited to adjoining the fourth groove bottom surface 261. It can be between the fourth side surface 216 and the fourth groove bottom surface 261 as the structural strength permits. Of course, the closer the fourth socket 284 is to the fourth groove bottom surface 261, the farther it is from the fourth side surface 216, and the stronger the structural strength is.
