[0002] During the chain processing, it is necessary to drill holes in the chain plates. During the drilling process, the chain plates need to be kept stable and not deflected. This process requires the use of positioning fixtures to clamp and fix the chain plates.

[0003] However, the current chain plate clamps are inconvenient to install, and most of them can only clamp chain plates of a single specification, and have poor versatility. In addition, there is no space for debris discharge after the clamp clamps the chain plate, and the cutting debris cannot be discharged during the hole opening process, which easily affects the hole opening quality. Therefore, in order to solve the above problems, it is considered to design a clamp with better versatility and the ability to discharge debris. In view of this, we propose a chain plate positioning clamp. Utility Model Content

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 7 The present invention describes the above technical solution in detail through the following embodiments:

[0035] A chain plate positioning fixture, comprising:

[0036] Fixture unit 2, such as Figure 1-Figure 3 The structure shown specifically includes a first clamping block 21 and a second clamping block 22 for clamping the chain plate body 1. The first clamping block 21 and the second clamping block 22 are provided with a chip guide slope 201; the chip guide slope 201 can make the chips fall during the cutting process, avoiding the problem of easy accumulation of chips in the planar structure.

[0037] In order to better clamp and fix the chain plate bodies 1 of different specifications, in this embodiment, the first clamping block 21 and the second clamping block 22 are respectively provided with a limit block 214 and a clamping block 223 for contacting and clamping the chain plate body 1; the first clamping block 21 and the second clamping block 22 are provided with a first supporting block 212 and a second supporting block 222 for lifting the chain plate body 1; It should be noted that, if Figure 1-Figure 3 As shown, the limit block 214 is provided with an arc surface structure that fits with the chain plate body 1. Figure 3The contact position can be adapted to different specifications, has a clamping effect, and improves the versatility of the clamp; the first clamping block 21 is located outside the limit block 214 and is provided with a side support block 213, and the side support block 213 is consistent in height with the first support block 212, further forming a gap space that is conducive to the discharge of debris.

[0038] Positioning clamping part, such as Figure 4-Figure 7 The structure shown in FIG. 1 includes two symmetrically arranged mobile support units 3 for mounting a first clamping block 21 and a second clamping block 22 respectively. Specifically, in this embodiment, the mobile support unit 3 includes a support body 31 with a mounting bracket 32 ​​on the top, a horizontal positioning bracket 33 with a socket 331 mounted on the mounting bracket 32, and a threaded hole 311 corresponding to the socket 331 is provided on the support body 31. It should be noted that, as Figure 1 and Figure 2 As shown in the structure, in this embodiment, a first mounting hole 211 and a second mounting hole 221 corresponding to the threaded hole 311 are respectively provided on the first clamping block 21 and the second clamping block 22, and bolts for fixing the first clamping block 21 and the second clamping block 22 are installed between the threaded hole 311 and the insertion hole 331. The arrangement of this structure can facilitate the disassembly and assembly of the clamp unit 2, providing convenience for later replacement.

[0039] It should be noted that the clamp unit 2 itself cannot clamp and requires external force. In this embodiment, the movable pallet unit 3 is movably installed on the base plate 5. Specifically, a guide rail 6 is installed on the base plate 5, and a slider 34 for slidingly installed on the guide rail 6 is provided under the pallet body 31; in order to facilitate the loosening and clamping of the clamp unit 2, in this embodiment, support blocks 312 are provided on the outside of the pallet body 31 on both sides, and a cylinder 4 is installed on the base plate 5 outside the support block 312. The output shaft of the cylinder 4 is connected to the support block 312, and the movable pallet unit 3 is driven to move by the extension and contraction of the output shaft of the cylinder 4, thereby realizing the clamping or separation of the first clamping block 21 and the second clamping block 22. In this process, the driving source cylinder 4 provides the opposite clamping force for the clamp unit 2.

[0040] The chain plate positioning fixture of this embodiment works as follows: first, the fixture unit 2 is positioned as Figure 4 Installed on the mobile support unit 3, the chain plate body 1 is compressed by the cylinder 4 so that the chain plate body 1 is fixed between the first clamping block 21 and the second clamping block 22, because the clamping block 223 on one side is as shown in FIG. Figure 1 and Figure 2 The surface shown is flat, so the chain plate bodies 1 of the same specifications can obtain consistent positioning positions after clamping, which is convenient for subsequent processing and opening.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
