Description

Explosion-proof box in coal mine, manual and automatic grinding device Technical Field

[0001] This utility model belongs to the field of coal mine explosion-proof box production technology, and provides a manual and automatic grinding device for coal mine explosion-proof boxes that reduces the labor intensity of workers, improves grinding efficiency, and reduces the manufacturing cost of enterprises. Background Technology

[0002] In the current production process of explosion-proof boxes for underground coal mines, the lower box body and the box cover need to be polished before assembly. Referring to Figure 1, the current polishing process for the lower box body involves workers using hand-held grinders to polish the four side panels (1) and the bottom panel (2) of the lower box body. This polishing efficiency is low and the labor intensity of workers is high. Alternatively, large grinding machines are used to polish the lower box body, and then workers use hand-held grinders to correct and polish burrs or flash. However, this method involves high equipment investment costs for enterprises, and large grinding machines are not suitable for small and medium-sized enterprises.

[0003] Designing a manual / automatic grinding device for explosion-proof boxes in coal mines that reduces worker labor intensity, improves grinding efficiency, and lowers enterprise manufacturing costs is necessary for small and medium-sized enterprises. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a manual and automatic grinding device for explosion-proof boxes in coal mines that reduces the labor intensity of workers, improves grinding efficiency, and reduces the manufacturing cost of enterprises.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a hand-operated and automatic grinding device for explosion-proof boxes in coal mines, including a support frame, a workpiece support lateral movement mechanism and a grinding machine support mechanism mounted on the support frame; wherein: the grinding machine support mechanism is fixed on the grinding machine vertical movement mechanism, and the grinding machine support mechanism includes a support base, positioning mounting ears fixed on the support base, and an elastic buckle fixed to the positioning mounting ears by bolts a, the elastic buckle having a mounting cavity and an opening, and bolts b passing through the opening fixing the hand-operated grinding machine in the mounting cavity; the positioning mounting ears are two pieces, and a limit plate is provided between the two positioning mounting ears;

[0007] The workpiece support lateral movement mechanism includes a workpiece support plate, which is fixed on a rotating disk. The rotating disk is threadedly connected to a support slide a. The support slide a is rotatably connected to a lead screw a. The two ends of the lead screw a are located on two lead screw seats a. The two lead screw seats a are fixed on a support frame. The support slide a is slidably connected to the top surface of the support plate. The support plate is fixed on the support frame.

[0008] Under the action of external force, rotating screw a pushes the support slide a to move left and right on the top surface of the support plate.

[0009] To facilitate control of the vertical movement of the grinding machine support mechanism, the above solution further includes: a support arm fixed on a support frame, two lead screw seats b fixed on the support arm, and a support slide b slidably connected to the front plate surface of the support arm; the bottom end of the lead screw b passes through the two lead screw seats b in sequence and is rotatably connected to the support slide b; the support seat is fixed on the support slide b.

[0010] Under the action of external force, rotating screw b pushes the support slide b to move up and down on the front plate surface of the support arm.

[0011] To facilitate the operation of the lead screw b to control the up and down movement of the support slide b, the above scheme further includes: a turntable b fixed to the top of the lead screw b, and a rocker arm b fixed on the turntable b.

[0012] To facilitate the operation of the lead screw a to control the left and right movement of the support slide a, the above scheme is further improved by fixing a turntable a at the left end of the lead screw a, and a rocker arm a is fixed on the turntable a.

[0013] The beneficial effects of this utility model are: reducing the labor intensity of workers, improving grinding efficiency, and reducing the manufacturing cost of enterprises.

[0014] Due to the aforementioned structure, the upper limit post achieves longitudinal positioning of the support cross plate, and the limiting longitudinal plate achieves lateral positioning of the support cross plate. This allows the two support seat limiting grooves located on the support cross plate to directly position the U-shaped mounting seat. Simultaneously, during welding, the U-shaped mounting seat can be precisely positioned and clamped to the designed welding position on the side wall of the housing. This improves welding quality and production efficiency. Attached Figure Description

[0023] As shown in Figures 2 to 4, this utility model provides a hand-operated and automatic grinding device for explosion-proof boxes in coal mines, including a support frame 3, a workpiece support lateral movement mechanism 4 and a grinding machine support mechanism 5 disposed on the support frame 3; wherein: the grinding machine support mechanism 5 is fixed on the grinding machine vertical movement mechanism 6, the grinding machine support mechanism 5 includes a support base 501, a positioning mounting ear 502 fixed on the support base 501, and an elastic buckle 504 fixed on the positioning mounting ear 502 by bolt a 503, the elastic buckle 504 having a mounting cavity 505 and an opening 506, and a bolt b 507 passing through the opening 506 fixing the hand-operated grinding machine 7 in the mounting cavity 505; the positioning mounting ear 502 consists of two pieces, and a limit plate 508 is provided between the two positioning mounting ears 502;

[0024] The workpiece support lateral movement mechanism 4 includes a workpiece support plate 401, which is fixed on a rotating disk 402. The rotating disk 402 is threadedly connected to a support slide a403. The support slide a403 is rotatably connected to a lead screw a404. The two ends of the lead screw a404 are located on two lead screw seats a405, which are fixed on a support frame 3. The support slide a403 is slidably connected to the top surface of a support plate 406, which is fixed on the support frame 3.

[0025] Under the action of external force, the rotating screw a404 pushes the support slide a403 to move left and right on the top plate surface of the support plate 406. In this embodiment, during use, the longitudinal movement of the workpiece is achieved by the relative longitudinal position of the support arm 601 of the vertical moving mechanism 6 of the grinder installed by the worker and the workpiece support transverse moving mechanism 4. The limiting plate 508 set between the two positioning mounting ears 502 can effectively ensure the switching between parallel and perpendicular between the grinding surface of the handheld grinder 7 and the side plate surface 1 of the lower box. If the grinding surface of the handheld grinder 7 is parallel to the side plate surface 1 of the lower box in the original state (as shown in Figure 2), then the handheld grinder 7 is used to grind the side plate surface 1 of the lower box in this state; by laying down the connecting plate of the elastic buckle 504 and pressing it tightly against the limiting plate 508, and then using the fastening bolt b507 to make the grinding surface of the handheld grinder 7 perpendicular to the side plate surface 1 of the lower box, the handheld grinder 7 is used to grind the bottom plate surface 2 of the lower box in this state.

[0026] To facilitate control of the vertical movement of the grinding machine support mechanism 5, in the above embodiment, preferably: the grinding machine vertical movement mechanism 6 includes a support arm 601 fixed on the support frame 3, two lead screw seats b602 fixed on the support arm 601, and a support slide b603 slidably connected to the front plate surface of the support arm 601; the bottom end of the lead screw b604 passes through the two lead screw seats b602 in sequence and is rotatably connected to the support slide b603; the support seat 501 is fixed on the support slide b603.

[0027] Under the action of external force, the rotating lead screw b604 pushes the support slide b603 to move up and down on the front plate surface of the support arm 601. In this embodiment, the support arm 601 can also be directly fixed to the ground.

[0028] To facilitate the operation of the lead screw b604 to control the up and down movement of the support slide b603, in the above embodiment, preferably, a turntable b605 is fixed to the top of the lead screw b604, and a rocker arm b606 is fixed on the turntable b605.

[0030] Referring to Figure 2, the grinding process is as follows: First, the worker inverts the lower housing and fixes it to the workpiece support plate 401 by screws passing through the top cover connection hole 8 on the lower housing; then, the handheld grinder 7 is fixed in the mounting cavity 505 by bolts b507 passing through the opening 506, so that the grinding surface of the handheld grinder 7 faces the surface to be ground; next, the worker shakes the rocker arm b606 to make the grinding surface of the handheld grinder 7 contact the surface to be ground and turns on the control switch of the handheld grinder 7; finally, the worker shakes the rocker arm a408 to move the surface to be ground of the lower housing back and forth on the grinding surface of the handheld grinder 7 to achieve grinding. Once burrs or flash are generated, the worker removes bolts b507 and removes the handheld grinder 7 from the opening 506 for manual grinding. The entire process reduces the labor intensity of workers, improves grinding efficiency, and reduces the manufacturing cost of enterprises.

[0031] All components in the above embodiments are commercially available products.
