Description

Technical Field

[0001] This invention belongs to the field of torque tooling technology, and particularly relates to a bolt terminal torque tooling. Background Technology

[0002] The primary function of high-reliability lead-insulated bolt terminals in batteries is to provide reliable electrical connections and mechanical support. These bolt terminals are typically made of stainless steel, which offers excellent electrical conductivity and corrosion resistance. Torque fixtures are fabricated to test the bonding strength between the bolt and the lead alloy, facilitating the reliability testing of the bolt terminals. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention proposes the following technical solution:

[0004] A bolt terminal torque fixture includes a base, a first fixing block is connected to the middle of the top of the base in a front-to-back adjustment manner, and a product with bolts is sleeved on the outer wall of the first fixing block. A second fixing block is connected to the rear side of the top of the base through a moving mechanism. The inner outer wall of the second fixing block abuts against the outer wall of the product with bolts. A nut is sleeved on the outer wall of the bolt at the rear top of the product with bolts.

[0005] Place the product with bolts on the base and fix it with the first fixing block and the second fixing block. Then, connect the nut to the bolt at the top of the product with bolts. Use a torque wrench to turn the nut to obtain the bolt torque at the top of the product with bolts.

[0006] As a preferred embodiment of the above technical solution, an inverted "T"-shaped groove is provided at the center of the top of the base, and the bottom end of the first fixing block slides inside the groove.

[0007] The first fixing block can move back and forth by using the sliding groove at the top of the base, realizing the commonality of multiple specifications of bolt terminals.

[0008] As a preferred embodiment of the above technical solution, the moving mechanism includes a limiting slot formed at the top rear side of the base, and a bidirectional lead screw is installed in the middle of the inner wall of the limiting slot. The outer wall of the bidirectional lead screw is symmetrically threaded with threaded sleeve blocks. The outer top of the bidirectional lead screw penetrates the outer wall of the base and is installed in the middle of the inner wall of the throttle. The top of the threaded sleeve block is installed at the bottom of the connecting plate. The top of the connecting plate is installed in the middle of the bottom of the bearing plate. A second fixing block is installed at the top of the bearing plate through a limiting mechanism.

[0009] The moving mechanism enables the two sets of bearing plates, along with the second fixed block, to move left and right. Combined with the inverted "T"-shaped sliding groove at the top of the base, it enables the commonality of multiple specifications of bolt terminals.

[0010] As a preferred embodiment of the above technical solution, the limiting mechanism includes fixed protrusions that are equidistantly installed at the bottom of the second fixed block, and the bottom ends of the fixed protrusions are all inserted into the top of the bearing plate. The fixed protrusions are in the shape of an inverted "mushroom".

[0011] The use of the limiting mechanism makes it easy to replace and install the second fixing block, allowing the second fixing block to clamp products with bolts of different specifications, thus ensuring the working efficiency of the device during use.

[0012] The beneficial effects of this invention are as follows:

[0013] (1) It can detect the torque of bolt terminals of different types;

[0014] (2) Easy to connect and disconnect, and reusable. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment of the invention: a base 1 is included, a first fixing block 2 is connected to the middle of the top of the base 1 in a front-to-back adjustment, and a product 3 with bolts is sleeved on the outer wall of the first fixing block 2. A second fixing block 4 is connected to the rear side of the top of the base 1 through a moving mechanism. The inner outer wall of the second fixing block 4 abuts against the outer wall of the product 3 with bolts. A nut 5 is sleeved on the outer wall of the bolt at the rear top of the product 3 with bolts.

[0023] Place the product 3 with bolts on the base 1 and fix it with the first fixing block 2 and the second fixing block 4. Then, connect the nut 5 to the bolt at the top of the product 3 with bolts. Use a torque wrench to turn the nut 5 to obtain the bolt torque at the top of the product 3 with bolts.

[0024] like Figure 1 and Figure 2 As shown, an inverted "T"-shaped groove is provided at the top center of the base 1, and the bottom end of the first fixing block 2 slides inside the groove.

[0025] The first fixing block 2 can move back and forth under the action of the sliding groove at the top of the base 1, realizing the commonality of multiple specifications of bolt terminals.

[0026] like Figure 3 and Figure 4 As shown, the moving mechanism includes a limiting slot 11 opened at the top rear side of the base 1, and a bidirectional lead screw 10 is installed in the middle of the inner wall of the limiting slot 11. A threaded sleeve block 9 is symmetrically threaded on the outer wall of the bidirectional lead screw 10. The top outer end of the bidirectional lead screw 10 passes through the outer wall of the base 1 and is installed in the middle of the inner wall of the throttle 12. The top end of the threaded sleeve block 9 is installed at the bottom end of the connecting plate 8. The top end of the connecting plate 8 is installed at the middle of the bottom end of the bearing plate 7. A second fixing block 4 is installed at the top end of the bearing plate 7 through the limiting mechanism.

[0027] The use of the moving mechanism enables the two sets of bearing plates 7, along with the second fixing block 4, to move left and right. In conjunction with the inverted "T"-shaped sliding groove at the top of the base 1, the commonality of multiple specifications of bolt terminals is achieved.

[0028] like Figure 4 As shown, the limiting mechanism includes fixing protrusions 6 that are equidistantly installed at the bottom of the second fixing block 4, and the bottom ends of the fixing protrusions 6 are all inserted into the top of the bearing plate 7. The fixing protrusions 6 are in the shape of an inverted "mushroom".

[0029] The use of the limiting mechanism makes it easy to replace and install the second fixing block 4, allowing the second fixing block 4 to clamp products 3 with bolts of different specifications, thus ensuring the working efficiency of the device during use.

[0030] Working principle: The product 3 with bolts is placed on the base 1 and fixed by the first fixing block 2 and the second fixing block 4. Then, the nut 5 is connected to the bolt at the top of the product 3 with bolts. By turning the nut 5 with a torque wrench, the torque of the bolt at the top of the product 3 with bolts can be obtained. Secondly, in order to achieve the commonality of multiple bolt terminal specifications, the first fixing block 2 can move back and forth under the action of the sliding groove at the top of the base 1, and the second fixing block 4 can move left and right with the cooperation of the moving mechanism.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
