[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0034] The embodiments of the present application provide a bench vice for multi-surface clamping, which solves the problem that the existing bench vice cannot clamp the multiple surfaces of the clamping piece synchronously, and improves the machining effect of the clamping piece.
[0035] The technical scheme in the embodiments of the present application is to solve the above technical problems, and the general idea is as follows:
[0036] In the prior art, the bench vice clamps two surfaces of the clamping piece during use to facilitate machining of the clamping piece. However, the existing bench vice cannot clamp the multiple surfaces of the clamping piece synchronously, which results in low stability of the clamping piece when clamped, and thus the machining effect of the clamping piece is poor.
[0037] It is found through research that, as shown in the drawings, by setting an extension block and a cam on the extension block, the cam on the extension block is used to abut against the clamping piece when the positioning block and the sliding block clamp the clamping piece, which realizes multi-surface clamping of the clamping piece, improves the stability of the clamping piece when clamped, and enhances the subsequent machining effect of the clamping piece. Figures 1-5
[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0039] Example:
[0040] like Figures 1-5 As shown, a multi-faceted clamping bench vise includes a base 1 and a positioning block 10 and a limiting block 12 arranged in parallel on the base 1.
[0041] The positioning block 10 and the limiting block 12 are located at both ends of the base 1, and are both fixedly connected to the base 1.
[0042] A drive rod 121 is installed on the limiting block 12. The outer surface of the middle section of the drive rod 121 is provided with threads to form a threaded section, and is threadedly connected to the limiting block 12 through the threaded section.
[0043] A slider 11 is also installed on the base 1. The slider 11 is located between the positioning block 10 and the limiting block 12, and is slidably connected to the base 1 through a sliding groove.
[0044] The end of the drive rod 121 near the slider 11 extends into the interior of the slider 11 and is rotatably connected to the slider 11. The drive rod 121 drives the slider 11 to move closer to or away from the positioning block 10. The gap formed between the slider 11 and the positioning block 10 is used to clamp the clamping member 3.
[0045] The bench vise is also equipped with multiple extension blocks 20, which are located on the base 1, the positioning block 10 and the slider 11 respectively. Each extension block 20 is equipped with a cam 23, and each cam 23 is rotatably connected to the corresponding extension block 20.
[0046] By setting an extension block 20 and a cam 23 on the extension block 20, when the positioning block 10 and the slider 11 clamp the clamping part 3, the cam 23 on the extension block 20 abuts against the clamping part 3, thereby achieving multi-face clamping of the clamping part 3, improving the stability of the clamping part 3 when it is clamped, and enhancing the subsequent processing effect of the clamping part 3.
[0047] Specifically, each of the cams 23 is made of metal and the surface of the metal is covered with rubber. By covering the metal cams 23 with rubber, the contact force between the cams 23 and the clamping member 3 can be effectively strengthened, and the stability of the clamping member 3 when it is clamped can be further improved.
[0048] Each of the extension blocks 20 has multiple positioning holes 21, and each of the cams 23 is welded with a bolt 22. Each of the cams 23 is rotatably connected to the corresponding extension block 20 through the positioning hole 21 via the bolt 22.
[0049] By setting multiple positioning holes 21 on the extension block 20, the adjustment of the position of the cam 23 is realized by using multiple positioning holes 21, so that the cam 23 is convenient for abutting against clamping pieces 3 of different lengths.
[0050] The base 1, the positioning block 10 and the sliding block 11 are respectively provided with multiple mounting holes 2, and the multiple mounting holes 2 on the base 1 are respectively located on both sides of the base 1 and are arranged along the sliding direction of the sliding block 11.
[0051] Each mounting hole 2 is matched with a positioning hole 21.
[0052] During installation, the fixing bolt is used to pass through the corresponding mounting hole 2 and the positioning hole 21, so as to realize the installation of the extension block 20 and the bench vice.
[0053] By setting the mounting hole 2, the mounting hole 2 is combined with the positioning hole 21, so that the installation between the extension block 20 and the bench vice is facilitated.
[0054] The positioning block 10 is provided with a clamping block one 101 on the side close to the sliding block 11, and the clamping block one 101 is made of elastic material, and the elastic material is hard rubber.
[0055] The sliding block 11 is provided with a clamping block two 111 on the side close to the positioning block 10, and the clamping block two 111 is the same as the clamping block one 101.
[0056] By setting the clamping block one 101 and the clamping block two 111, the hard material of the clamping block one 101 and the clamping block two 111 is used to contact the clamping piece 3, and the elasticity of the hard material is used to improve the stability of clamping.
[0057] Specifically, the positioning hole 21 and the mounting hole 2 are threaded holes.
[0058] The driving rod 121 is provided with a through hole at the end away from the sliding block 11, and the driving rod 121 is provided with a labor-saving rod 122, and the labor-saving rod 122 is in sliding connection with the driving rod 121 through the through hole and does not deviate from the driving rod 121.
[0059] By setting the labor-saving rod 122 on the driving rod 121, the rotation of the driving rod 121 is facilitated by pulling the labor-saving rod 122, and the labor-saving rod 122 is arranged in the form of sliding with the driving rod 121. When the labor-saving rod 122 is rotated to a position where it is not convenient to continue to pull, the labor-saving rod 122 is extracted from the other side of the through hole to continue to pull, so that the control of the driving rod 121 by the labor-saving rod 122 is facilitated.
[0060] In work, the driving rod 121 is controlled to rotate by the labor-saving rod 122. Since the driving rod 121 is threadedly connected with the limiting block 12, and the end of the driving rod 121 close to the sliding block 11 extends into the interior of the sliding block 11 and is rotationally connected with the sliding block 11, when the driving rod 121 rotates, the sliding block 11 is driven to move close to or away from the limiting block 10, and the clamping piece 3 is clamped by the spacing between the limiting block 10 and the sliding block 11.
[0061] After clamping, according to the length of the clamping piece 3 and actual requirements, a plurality of extension blocks 20 with appropriate lengths are selected and installed on the base 1, the limiting block 10 and the sliding block 11, and the cam 23 is rotated to an appropriate position to clamp the clamping piece 3, so that multi-surface clamping of the clamping piece 3 is realized. The arrangement and use of the extension blocks 20 and the cam 23 are specifically shown in the following table. Figures 4-5
[0062] The multi-surface clamping of the clamping piece 3 by the extension blocks 20 and the cam 23 facilitates the stability of the clamping piece 3 during machining.
[0063] It should be noted that the distance between the farthest end of the cam 23 and the rotation axis of the cam 23 is less than 1 cm, and the distance between the farthest end of the cam 23 and the center of the bolt 22 is greater than the distance from the center of the bolt 22 to the clamping piece 3. The bolt 22 for controlling the rotation of the cam 23 needs to be controlled by a screwdriver to rotate the bolt 22, thereby driving the corresponding cam 23 to rotate to the position abutting against the clamping piece 3, thereby improving the stability of the abutment of the cam 23 against the clamping piece 3.
[0064] Compared with the prior art, the present application has the following advantages:
[0065] 1. By arranging the extension blocks 20 and the cams 23 on the extension blocks 20, the cams 23 on the extension blocks 20 are used to abut against the clamping piece 3 when the limiting block 10 and the sliding block 11 clamp the clamping piece 3, thereby realizing multi-surface clamping of the clamping piece 3, improving the stability of the clamping piece 3 during clamping, and enhancing the machining effect of the clamping piece 3.
[0066] 2. By arranging a plurality of positioning holes 21 on the extension blocks 20, the positions of the cams 23 are adjusted by the plurality of positioning holes 21, thereby facilitating the abutment of the cams 23 against clamping pieces 3 of different lengths.
[0067] 3. By arranging the clamping block one 101 and the clamping block two 111, the clamping block one 101 and the clamping block two 111 are used to contact the clamping piece 3, and the elasticity of the hard material improves the stability of clamping.
