For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as there is no conflict between them.

[0028] The utility model provides a kind of Figure 1 And Figure 2As shown, a frame workpiece clamp, a device for fixing the frame workpiece, ensures that the frame workpiece is accurate and stable in position during operation, thereby ensuring machining precision and quality. For example, in the machining of the frame of a mobile phone, the clamp can fix the frame, facilitating cutting, drilling and other operations. The main structure of the utility model comprises: a mounting base 1 and a workpiece clamp 2, one end of the mounting base 1 is provided with a mounting head 11; the workpiece clamp 2 comprises a first clamping plate 21 and a second clamping plate 22, the first clamping plate 21 and the second clamping plate 22 are connected in a stackable and detachable manner, and the first clamping plate 21 and the second clamping plate 22 are respectively used for abutting against the upper and lower end faces of the frame workpiece. Among them, one end of the first clamping plate 21 and the second clamping plate 22 away from the frame workpiece is provided with a mounting part 211, and the mounting part 211 is detachably connected with the mounting head 11. The mounting part 211 is matched with the mounting head 11. And the mounting part 211 and the mounting head 11 form a plug-in connection mode. So that the two can realize the quick disassembly and assembly connection structure. To improve the efficiency of the workpiece clamp 2. In some embodiments, the mounting base 1 and the mounting head 11 are integrally formed. The workpiece clamp 2 is a metal structure clamp to improve the durability of the workpiece clamp 2. So that it can clamp the frame workpiece repeatedly, prolong the service life of the workpiece clamp 2.

[0029] It should be noted that the frame workpiece clamp 2 of the prior art needs to be loosened after machining one side, and then the workpiece needs to be turned over and clamped again. This workpiece clamp 2 is not flexible enough to affect the machining efficiency. The present scheme first clamps the frame workpiece by the first clamping plate 21 and the second clamping plate 22, and then installs the workpiece clamp 2 on the mounting head 11 of the mounting base 1 through the mounting surface for machining equipment to finish machining the workpiece. When the upper end face of the workpiece is machined, turn the workpiece clamp 2 over, install the workpiece clamp 2 on the mounting head 11 through another mounting surface, and make the lower end face of the workpiece face upward for machining. This effectively improves the flexibility of machining the frame workpiece.

[0030] Further, as shown in Figure 2 and Figure 3 , a mounting groove 212 is formed on the mounting part 211, and the mounting groove 212 is matched with the mounting head 11. It can be understood that when the workpiece clamp 2 is installed on the mounting base 1, the mounting head 11 only needs to be butt jointed with the mounting groove 212. In order to avoid loosening of the workpiece clamp 2 on the mounting base 1, the mounting groove 212 needs to be matched with the mounting head 11. Among them, the shape of the mounting groove 212 and the mounting head 11 can be rectangular or geometric, so as to prevent the workpiece clamp 2 from rotating on the mounting base 1.

[0031] Further, as shown in Figure 2 and Figure 3As shown, the mounting head 11 is provided with at least one first plug-in pin 111, and the mounting groove 212 is provided with a first plug-in groove 213 corresponding to the position of the first plug-in pin 111, and the first plug-in groove 213 is inserted into the first plug-in pin 111 in an interference fit. In some embodiments, the mounting head 11 is in a cylindrical structure, and the mounting groove 212 is a circular groove. The first plug-in pin 111 provided on the mounting head 11 can make the mounting head 11 and the workpiece clamp 2 accurately butt joint.

[0032] Further, the first plug-in pin 111 is detachably connected to the mounting head 11. It can be understood that the long-time and high-frequency plug-in between the workpiece clamp 2 and the mounting base 1 will cause the first plug-in pin 111 to be worn, and the connection structure between the workpiece clamp 2 and the mounting base 1 will have a gap. Eventually, it will affect the machining accuracy of the frame workpiece. In the present embodiment, when the first plug-in pin 111 is worn seriously, the worker can detach and replace the new first plug-in pin 111, which can further improve the service life of the workpiece clamp 2.

[0033] Further, as shown in Figure 2 At least one first plug-in pin 111 is eccentrically arranged on the mounting head 11. In some embodiments, the mounting head 11 is in a cylindrical structure, and the mounting groove 212 is a circular groove. In order to prevent the workpiece clamp 2 from rotating on the mounting base 1, the first plug-in pin 111 needs to be eccentrically arranged on the mounting head 11. The plug-in pin is used to avoid the workpiece clamp 2 from rotating on the mounting base 1.

[0034] Further, as shown in Figure 2 and Figure 3 The first clamping plate 21 is provided with a plurality of second plug-in pins 214, and the second clamping plate 22 is provided with a second plug-in groove 221 corresponding to the position of the second plug-in pin 214, and the second plug-in groove 221 is inserted into the second plug-in pin 214 in an interference fit.

[0035] It can be understood that in the present embodiment, the second plug-in groove 221 and the second plug-in pin 214 are used to align and plug-in the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 can accurately and firmly fix the frame clamp.

[0036] Further, the second plug pin 214 is detachably connected to the first clamping plate 21. Similarly, long-term and high-frequency plugging between the first clamping plate 21 and the second clamping plate 22 can cause the second plug pin 214 to be worn, and a gap is generated in the connecting structure between the first clamping plate 21 and the second clamping plate 22. The frame workpiece cannot be stably fixed. Ultimately, it will affect the machining accuracy of the frame workpiece. In the embodiment, when the second plug pin 214 is worn seriously, the worker can detach and replace the second plug pin 214 with a new one, which can further improve the service life of the workpiece clamp 2.

[0037] Further, as shown in Figure 2 and Figure 3 , the first clamping plate 21 and the second clamping plate 22 are provided with arrow marks 222, which are used to mark the head and tail ends of the frame workpiece. The worker can distinguish the front end and the rear end of the frame workpiece according to the arrow marks 222. The working efficiency of the worker is higher.

[0038] Further, as shown in Figure 2 , at least one of the first clamping plate 21 and the second clamping plate 22 is provided with an abutting step 215, which is arranged around the edge of the first clamping plate 21 or the second clamping plate 22. The abutting step 215 is used to abut the frame workpiece. The frame workpiece can be fixed along the edge of the first clamping plate 21 or the second clamping plate 22, and the edge position of the frame workpiece can be exposed, which is convenient for the machining equipment to carry out finishing machining.

[0039] In summary, the present application provides a frame workpiece clamp 2. In use, the frame workpiece is first clamped by the first clamping plate 21 and the second clamping plate 22, and then the workpiece clamp 2 is installed on the mounting head 11 of the mounting base 1 through the mounting surface, so that the machining equipment can finish machining the workpiece. When the upper end surface of the workpiece is machined, the workpiece clamp 2 is turned over, and the workpiece clamp 2 is installed on the mounting head 11 through another mounting surface, so that the lower end surface of the workpiece faces upward for machining. This effectively improves the flexibility of machining the frame workpiece.

Based on the above description, those skilled in the art can make other different forms of changes or changes. Here, all the embodiments do not need to be exhausted. The obvious changes or changes derived therefrom are still within the protection scope of the present application.
