[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] It should be noted that when an element is referred to as being "disposed on" or "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, they may be fixed in a detachable manner or in a non-detachable manner. When an element is considered to be "connected" or "rotatably connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right", "upper", "lower" and similar expressions used are for illustrative purposes only and do not represent the only implementation method.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to restrict the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] The terms “first”, “second”, “third” and the like in the present invention do not represent specific quantities and sequences, but are merely used to distinguish names.

[0033] In some embodiments, reference Figure 1-Figure 2 As shown, a clamp of the utility model comprises:

[0034] A base 1 is provided on the base 1.

[0035] The placing table 2 is provided with

[0036] At least two support members 3, each of the two ends of the placement table 2 has at least one support member 3 to support the two ends of the workpiece, and the top of the placement table 2 is an inclined surface so that the workpiece is tilted and arranged on the placement table 2;

[0037] The clamping member 4 is provided with

[0038] The base 1 is also provided with a first positioning hole and a threaded hole.

[0039] The second positioning hole is provided with a

[0040] The positioning pin 5 passes through the first positioning hole and is adapted to the second positioning hole. The threaded hole is internally threaded with a

[0041] The bolt 6 is used to adjust the distance between the clamping member 4 and the workpiece.

[0042] The workpiece is placed on the placement table 2 arranged on the base 1. Since the top of the placement table 2 is an inclined surface, when the workpiece is placed on the placement table 2, there will be an angle between the workpiece and the horizontal plane. The angle is the same as the inclination of the inclined surface of the placement table 2. After the workpiece is placed on the placement table 2, the processing tool moves in the horizontal direction to process the structure of the required angle on the surface of the workpiece. By replacing the placement tables 2 with different inclinations, workpieces with different angle requirements can be processed, so that the fixture can adapt to the processing requirements of various workpieces. When clamping is required, the placement table 2 is placed on the base 1, and then the workpiece is placed on the placement table 2. The support member 3 can support the raised part of the workpiece, and at the same time, the position of the raised part of the workpiece and the support member 3 can be used to position the workpiece, so as to avoid the situation where the clamping is unstable due to the position deviation of the workpiece. Finally, the clamping member 4 is raised or lowered by rotating the bolt 6 under the restricted rotation of the positioning pin 5, thereby forming a loosening and clamping action on the workpiece.

[0043] In one embodiment, referring to Figure 1-Figure 2 As shown, there are two placing platforms 2 , and the two placing platforms 2 are respectively arranged on both sides of the clamping member 4 .

[0044] By providing two placement tables 2 to place two workpieces, the two workpieces can be processed simultaneously, thereby improving the processing efficiency.

[0045] In one embodiment, a third positioning hole is further provided on the placement platform 2 .

[0046] The third positioning hole provided on the placement table 2 can facilitate the positioning of the workpiece, thereby further improving the accuracy of the workpiece placement.

[0047] In one embodiment, referring to Figure 2 and Figure 3 As shown, an elastic member 7 and a sliding member 8 are further provided in the third positioning hole. The elastic member 7 is arranged at the bottom of the sliding member 8, and the top end of the sliding member 8 abuts against the workpiece to support the workpiece.

[0048] The sliding member 8 is arranged in the third positioning hole to support the raised portion of the workpiece. At the same time, the elastic member 7 can ensure that the sliding member 8 is in close contact with the workpiece, thereby further improving the stability of the workpiece after being clamped.

[0049] In one embodiment, referring to Figure 3As shown, a positioning groove is provided at the top end of the sliding member 8, and the positioning groove is adapted to the workpiece.

[0050] The positioning groove provided at the top of the sliding member 8 can make the raised portion of the workpiece fit more closely against the sliding member 8, and at the same time can prevent the horizontal movement of the workpiece to a certain extent, further improving the stability of the workpiece after being clamped.

[0051] In one embodiment, referring to Figure 3 As shown, the width of the positioning groove decreases as its depth increases.

[0052] Making the positioning groove into a funnel shape can further improve the stability of the part of the workpiece in the positioning groove and further reduce the horizontal displacement of the workpiece.

[0053] In one embodiment, referring to Figure 1 As shown, at least two clamping ends 401 are provided on one side of the clamping member 4, and the bottoms of the clamping ends 401 abut against the workpiece.

[0054] By providing at least two clamping ends 401 , at least two points of a single workpiece can be clamped, which is more stable than a single clamping point.

[0055] In one embodiment, referring to Figure 1 As shown, the bottom of the clamping end 401 is an inclined surface.

[0056] Setting the bottom of the clamping end 401 as an inclined surface can make the clamping end 401 and the workpiece fit over a larger area and fit more smoothly when clamping the workpiece, thereby further improving the stability of the workpiece when being clamped.

[0057] In one embodiment, referring to Figure 1-Figure 2 As shown, the number of the first positioning hole, the second positioning hole and the positioning pin 5 are all two, and the two positioning pins 5 are respectively arranged on both sides of the threaded hole.

[0058] The positioning pins 5 are arranged on both sides of the threaded hole to position the clamp 4 more stably, thereby preventing the clamp 4 from rotating along with the bolt 6 when driven by the bolt 6 , thereby improving the stability of the clamp 4 .

[0059] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
