[0003] In the process of manufacturing explosion-proof housings, the processing of the explosion-proof surface is the most critical step. The precision of milling can meet the technical requirements of the explosion-proof surface. However, due to the large size of the explosion-proof housing, the milling cutter obstructs the movement before and after processing, making it inconvenient to move. At the same time, the explosion-proof surface is located on the top boss of the explosion-proof housing, and the boss lacks effective support and is prone to deformation during milling. Therefore, this utility model proposes a mining explosion-proof housing processing fixture that can solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mining explosion-proof shell processing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mining explosion-proof shell processing fixture, comprising a base, two sets of vertical beams slidably fitted on the base, multiple sets of guide rods respectively passing through the vertical beams, a support seat for supporting the explosion-proof shell connected to the upper end of the multiple sets of guide rods, a seat block connected to the lower end of the support seat, and a recessed box for embedding the seat block on the base.

[0006] Two sets of pads are distributed on the upper part of the base. Each set of pads is equipped with two sets of clamping assemblies.

[0023] Please see Figure 1-4

[0024] Provides a machining fixture for explosion-proof housings used in mining:

[0025] The base 10 has two sets of vertical beams 20 slidably fitted together. Each of the two sets of vertical beams 20 is provided with multiple sets of guide rods 21. The upper ends of the multiple sets of guide rods 21 are connected to support seats 30. The support seats 30 are used to support the explosion-proof housing 50. The upper end of the support seats 30 is marked with a range that is adapted to the size of the explosion-proof housing 50 to be processed. When the explosion-proof housing 50 is placed, it is located within the range. The support seats 30 can move laterally on the base 10 via the two sets of vertical beams 20, thereby moving the placed explosion-proof housing 50 to or away from the milling cutter processing position. This allows for the handling and placement of the explosion-proof housing 50 before and after processing. The movement of the two sets of vertical beams 20 can be driven by external equipment such as linear electric cylinders.

[0026] The support base 30 has multiple sets of straight grooves that extend longitudinally and are open at both ends, allowing handling devices such as forklifts to extend the lifting plate into the straight grooves for picking and placing operations.

[0027] The lower end of the support base 30 is connected to the seat block 31. The base 10 has a recess 12 for the seat block 31 to be embedded. Each set of vertical beams 20 is equipped with a vertical cylinder 23. The vertical cylinder 23 is movably connected to the top plate 22. The top plate 22 is connected to the guide rod 21. When the explosion-proof housing 50 moves with the support base 30 to the milling cutter machining position, the movable rod of the vertical cylinder 23 retracts, so that the seat block 31 is embedded into the recess 12, and the support base 30 abuts against the two sets of vertical beams 20.

[0028] The caisson 12 is connected to a support column 13. The seat block 31 has a slot 32 that is adapted to be inserted into the support column 13. The top of the support column 13 has a guide section. The outer diameter of the guide section gradually decreases from bottom to top, so that when the seat block 31 is embedded into the caisson 12, the support column 13 is inserted into the slot 32, which guides the position of the seat block 31 embedded into the caisson 12, so that the support seat 30 is limited and remains stable when the explosion-proof surface of the explosion-proof housing 50 is processed.

[0029] Two sets of pads 11 are distributed on the upper end of the base 10. Each set of pads 11 is equipped with two sets of clamping assemblies 40. The clamping assembly 40 includes a horizontal cylinder 41 and a pressure frame 42. The pressure frame 42 is hinged to the pad 11. The horizontal cylinder 41 is connected to the pressure frame 42 through a transmission part. It is used to drive the pressure frame 42 to pivot and then cooperate with the support seat 30 to clamp the bottom boss of the explosion-proof housing 50. The transmission part includes a bracket 43 fixed on the pad 11. The bracket 43 is hinged to a bracket 44. The bracket 44 is connected to the pressure frame 42 through a pivot arm 441. The bracket 44 has a waist groove. The horizontal cylinder 41 is movably connected to a moving block 411. The moving block 411 is connected to a locking post that is movably engaged with the waist groove.

[0030] When clamping, the movable rod of the horizontal cylinder 41 extends, the moving block 411 pushes the bracket 44 to rotate through the locking pin, and the bracket pushes the pressure frame 42 to rotate downward through the pivot arm 441, thereby cooperating with the support seat 30 to clamp the bottom boss of the explosion-proof housing 50, effectively ensuring the machining accuracy of the explosion-proof housing 50.

[0031] Each set of pressure frames 42 is equipped with a lifting part, which is used to support the top boss of the explosion-proof housing 50. The lifting part includes a liner 45, and an adjusting rod 46 is screwed to the liner 45. A support plate 47 is rotatably connected to the upper end of the adjusting rod 46, and the support plate 47 has a moving rod 471 passing through the liner 45. The support plate 47 includes a first support bar and a second support bar that are vertically connected.

[0032] After the explosion-proof housing 50 is clamped, the support plate 47 is moved upward by rotating the adjusting rod 46, so that the support plate 47 supports the top boss of the explosion-proof housing 50. The first support bar and the second support bar included in the support plate 47 extend to different edges of the top boss, so that the top boss is not easily deformed when the explosion-proof surface is processed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
