Description

Technical Field

[0001] This utility model relates to the field of positioning pin technology, specifically to a positioning pin for preventing damage to the fixture base. Background Technology

[0002] The fixing pins of the fixture base limit the mold stroke, preventing the punch and die from deforming due to overload or prolonged use, thus ensuring stable molding accuracy. At the same time, in progressive dies, the fixing pins can effectively reduce the creep deformation of the template caused by high-speed impact, ensuring the service life of the mold.

[0003] However, the existing fixture base uses a simple structure for the main pressure-resistant part of the fixing pin. As the fixture base is subjected to pressure, the pressure-resistant part of the existing fixing pin is the first to wear. Once the wear increases, the fixture base will become loose and produce abnormal noises.

[0004] Therefore, a positioning pin was designed to prevent damage to the fixture base in order to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing positioning pins for preventing damage to the clamp base.

[0026] Example 1:

[0027] Combination Figures 1 to 4 As shown, the positioning pin for preventing damage to the fixture base provided by this utility model includes a pin 100, a fixture hole protection mechanism 200 disposed outside the pin 100, and an anti-slip sleeve 300 inserted outside the fixture hole protection mechanism 200. The fixture hole protection mechanism 200 is used to cooperate with the pin 100 to enhance the stability and pressure bearing of the fixture base, and to provide wear protection for the pressure-bearing part of the pin 100.

[0028] The pin 100 has a T-shaped structure as a whole, and the top of the pin 100 has a hemispherical structure;

[0029] The clamp hole protection mechanism 200 includes multiple inner pressure pads 240 and multiple outer tension stabilizing pads 250. The outer tension stabilizing pads 250 have through holes 2501 and hole edge grooves 2502 on their outer walls. Reinforcing rings 260 are fixedly installed inside the multiple outer tension stabilizing pads 250. The inner pressure pads 240 are adapted to fit against the inner walls of the outer tension stabilizing pads 250. Reinforcing sleeves 230 are fixedly installed at the bottom of the multiple inner pressure pads 240. The bottom of the reinforcing sleeves 230 is snapped with buckles 220. Hexagonal nuts 210 are fixedly installed at the bottom of the buckles 220. The outer surface of the outer tension stabilizing pads 250 is provided with an anti-slip layer, and the top plate of the outer tension stabilizing pads 250 is adapted to bear pressure on the clamp base.

[0030] The anti-slip sleeve 300 is made of rubber material, and the top of the anti-slip sleeve 300 is adapted to fit against the lower surface of the top plate of the outer tension stabilizing pad 250, and the bottom of the anti-slip sleeve 300 is adapted to bear pressure on the inner side of the hole edge slot 2502.

[0031] Anti-slip sleeves 300 are installed on the outside of multiple externally tensioned stabilizing pads 250.

[0032] When using it, first align the holes of the fixture base with the holes of the worktable. Then, insert multiple external stabilizing pads 250 and multiple internal pressure pads 240 into the two aligned holes. The reinforcing sleeves 230 fixed at the bottom of the multiple internal pressure pads 240 need to penetrate below the worktable. Then, insert the threaded section of the pin 100 into the inside of the multiple internal pressure pads 240 until the threaded section of the pin 100 extends out of the limiting hole 2302 and is fitted into the threaded hole inside the hexagonal nut 210. Use a wrench to adjust the hexagonal nut 210 until the pin 100 and the hexagonal nut 210 quickly clamp the fixture base and the worktable.

[0033] As the hexagonal nut 210 continues to rotate along the threaded section of the pin 100, until the inner pressure pad 240 applies pressure to the outer expansion stabilizing pad 250 and expands outward, the anti-slip sleeve 300, which is fitted onto the outside of the multiple outer expansion stabilizing pads 250, can further enhance the bearing pressure on the fixture base and the worktable hole wall, and the hole edge slot 2502 will also be locked onto the side of the bottom end of the worktable hole.

[0034] Example 2:

[0035] Combination Figure 3 and Figure 4 As shown, in the above embodiment, the top of the reinforcing sleeve 230 is provided with a plurality of pre-installed insertion holes 2301 evenly distributed, and the inside of the reinforcing sleeve 230 is provided with a limiting hole 2302, and the threaded section of the pin 100 is adapted to pass through the limiting hole 2302.

[0036] The internal pressure pad 240 is composed of an arc-shaped strip and a fan-shaped pad, and the outer end of the fan-shaped pad has a 30-degree angle with the vertical direction.

[0037] Preferably, the bottom of the reinforcing sleeve 230 is provided with two symmetrically distributed round pads, and one round pad at the bottom is adapted to be snapped into the buckle 220, while the other round pad is adapted to be attached to the top surface of the buckle 220.

[0038] The inner pressure pad 240 has a total length that is two-thirds the length of the outer expansion stabilizing pad 250, and is used to selectively adjust the expansion range of the lower half of the outer expansion stabilizing pad 250.

[0039] The working principle and usage process of this utility model are as follows: First, place the fixture base on the upper surface of the workbench. Then, align the holes in the fixture base with the holes in the workbench. Next, insert the anti-slip sleeve 300 along the outside of the multiple outer expansion stabilizing pads 250 until the anti-slip sleeve 300 is fitted and snapped by the hole edge slot 2502. Then, insert the combined multiple inner pressure pads 240 and reinforcing sleeves 230 through the gaps in the middle of the multiple outer expansion stabilizing pads 250. Then, insert the multiple outer expansion stabilizing pads 250 and reinforcing sleeves 230 through the holes in the fixture base and the holes in the workbench.

[0040] Then, the buckle 220 and the hexagonal nut 210 are inserted into the bottom of the reinforcing sleeve 230, and the bottom of the threaded section of the pin 100 is assembled along the threaded hole inside the hexagonal nut 210. The hexagonal nut 210 is adjusted with a wrench. As the hexagonal nut 210 rotates clockwise, the reinforcing sleeve 230 and multiple inner pressure pads 240 are pressed and fall down along the inner side of multiple outer stabilizing pads 250. Finally, the multiple evenly distributed outer stabilizing pads 250 are pressed by the multiple inner pressure pads 240 and work with the anti-slip sleeve 300 to further stabilize and clamp the hole wall of the fixture base, thereby ensuring that the fixture base receives effective pressure resistance support during the pressure period.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
