DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0029] See Figure 1 - Figure 4 The utility model provides a radial drilling machine processing fixture, including a base plate 100; a support frame 200, a side wall 210 of the support frame 200 is inclined upward, a positioning groove 211 and a first auxiliary positioning hole 212 are opened on the side wall 210, a first bolt 300 is passed through the first auxiliary positioning hole 212, and the first bolt 300 is used to fix the workpiece in an inclined state; the top end of the support frame 200 is detachably connected to a top plate 400, the top plate 400 is arranged parallel to the bottom plate 100, a second auxiliary positioning hole 410 is opened on the top plate 400, a second bolt 420 is passed through the second auxiliary positioning hole 410, and the second bolt 420 is used to fix the workpiece in a horizontal state.

[0030] When in use, first select whether to use the top plate 400 based on whether the workpiece to be processed is at an angle or in a horizontal state; when used to process a workpiece in a horizontal state, fasten the top plate 400 to the top of the support frame 200 with the second bolt 420, and fasten the fixture to the radial drilling machine for processing; when it is necessary to process an angled point to be processed, remove the top plate 400 and roughly position the workpiece through the positioning groove 211, then use at least two first bolts 300 to pass through different first auxiliary positioning holes 212 to fix the workpiece, and then process. Since the side wall 210 is set at an angle and the top plate 400 is set parallel to the bottom plate 100, this allows the processing fixture to adapt to points to be processed at different angles, which effectively improves the versatility of the processing fixture.

[0031] Furthermore, in one embodiment of the present invention, the positioning groove 211 is provided in the center of the side wall 210 , which makes it easier to take and place workpieces.

[0032] Furthermore, in one embodiment of the present invention, the first auxiliary positioning holes 212 are arranged in groups on both sides of the positioning groove 211. Each group of first auxiliary positioning holes 212 is arranged in a matrix, and at least one first bolt 300 is inserted into each group of first auxiliary positioning holes 212. Specifically, by providing multiple first auxiliary positioning holes 212, it can adapt to the fastening of workpieces of different sizes, effectively improving its versatility.

[0033] Furthermore, in one embodiment of the present invention, a square groove 220 is symmetrically provided on the top end surface of the support frame 200, and the top plate 400 is detachably connected to the square groove 220, so that the top plate 400 can be easily replaced, thereby better adapting to the processing of workpieces of different specifications.

[0034] Furthermore, in one embodiment of the present invention, an auxiliary positioning block 500 is detachably connected to the square groove 220. The auxiliary positioning block 500 is provided with at least one circular hole 510 and two first threaded holes 520. Two second threaded holes 430 are correspondingly provided on the top plate 400. The second threaded holes 430 are penetrated by fourth bolts 440. The fourth bolts 440 are used to fasten the top plate 400 to the auxiliary positioning block 500. A third bolt 530 is penetrated by the circular hole 510. The third bolt 530 passes through the circular hole 510 to fasten the auxiliary positioning block 500 to the support frame 200. It should be noted that the main purpose of the auxiliary positioning block 500 is to enhance the service life of the support frame 200 and enhance the support for the top plate 400.

[0035] Furthermore, in one embodiment of the present invention, a groove 230 is formed on the top end surface of the support frame 200. The groove 230 is disposed within the two square grooves 220. A centering plate 600 is detachably connected to the groove 230. A centering hole 610 is formed on the end of the centering plate 600 away from the support frame 200. Specifically, the centering hole 610 allows the drill bit to be centered on the workpiece and prevent the drill bit from wandering during operation.

[0036] Furthermore, in one embodiment of the present invention, a clearance hole 240 is provided on the other side wall 210 of the support frame 200 , so that the operator can conveniently position the tubular workpiece effectively through the pull rod.

[0037] In order to further enhance the stability of the support frame 200 , in one embodiment of the present invention, reinforcing ribs 250 are welded to the support frame 200 .

[0038] Furthermore, in one embodiment of the present invention, the support frame 200 and the base plate 100 are integrally formed.

[0039] Furthermore, in one embodiment of the present invention, four mounting feet 110 are symmetrically provided on the base plate 100 , so that the operator can conveniently fix the processing fixture through positioning holes and rivets.

[0040] It should be pointed out that the number of the first bolt 300, the second bolt 420, the third bolt 530 and the fourth bolt 440 is selected according to actual positioning needs. In principle, at least two of each are used, and they are used diagonally to facilitate tightening and disassembly.

[0041] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
