Description

Technical Field

[0001] The utility model belongs to the technical field of vertical lathes, and particularly relates to a pressing wheel device with pre-pressure display and adjustable function in front of the turning tool of a vertical lathe. Background Art

[0002] When the existing pressing wheel device in front of the turning tool of a vertical lathe is in use, by rotating the threaded rod, the driving plate moves downward, thereby pushing the spring. The spring pushes the frame of the nylon pressing wheel, and finally the nylon pressing wheel presses against the surface of the nylon plate part to position the surface of the nylon plate part. However, since the current spring is sleeved on the periphery of the threaded rod and the spring has a large elastic force, after the turning of the nylon plate part is completed, it is necessary to rotate the threaded rod in the reverse direction to reset the driving plate. When turning the next nylon plate part, it is necessary to manually push the frame of the nylon pressing wheel upward, and due to the large elastic force of the spring, it is difficult to push when pushing the frame, which is time-consuming and laborious.

[0003] Therefore, a pressing wheel device with pre-pressure display and adjustable function in front of the turning tool of a vertical lathe is needed to solve the problems of being difficult to push, time-consuming and laborious when pushing the frame in the prior art.

[0030] Please refer to Figures 1 - 6, the present utility model provides a pressure wheel device with pre-pressure display and adjustable function in front of a vertical lathe tool, including a top plate 100. On opposite sides of the top plate 100, side plates 101 are respectively fixed. Between the bottom surfaces of the two mutually approaching side surfaces of the two side plates 101, a bottom plate 102 is fixed. On the top surface of the bottom plate 102, a frame 200 is movably connected. Between the bottom surfaces of the mutually approaching side surfaces of the inner side walls of the frame 200, a nylon pressure wheel 201 is movably connected. On the top of one side surface of the nylon pressure wheel 201, a toothed plate 300 is fixed. On one side of the top surface of the bottom plate 102, a second threaded rod 700 is movably connected. The non-threaded position at the bottom of the outer side wall of the second threaded rod 700 is movably connected to the top surface of the bottom plate 102. A limiting frame 301 is threadedly connected to the outer side wall of the second threaded rod 700. A C-shaped frame 302 is movably engaged in the limiting frame 301. On the side surface of the C-shaped frame 302 close to the toothed plate 300, a toothed block 303 is fixed. The toothed block 303 meshes with the toothed plate 300.

[0031] Further, as Figure 2 shown, at the center of the top surface of the bottom plate 102, a connecting column 107 is movably connected. The connecting column 107 movably passes through the frame 200. On the top surface of the connecting column 107, a first threaded rod 106 is fixed. The non-threaded position at the top of the outer side wall of the first threaded rod 106 is movably connected to the top plate 100. On the top surface of the first threaded rod 106, a first handwheel 203 is fixed. On both sides between the mutually approaching side surfaces of the top plate 100 and the bottom plate 102, limiting columns 103 are respectively fixed. On the outer side walls of the two limiting columns 103, a driving plate 104 is movably connected. The driving plate 104 is threadedly connected to the first threaded rod 106.

[0032] By providing the first threaded rod 106, when the first threaded rod 106 rotates, it can drive the driving plate 104 and the hollow frame 105 to move downward. By providing the connecting column 107, the first threaded rod 106 can be movably connected to the bottom plate 102.

[0033] Further, as Figure 2 shown, at the center of the bottom surface of the driving plate 104, a hollow frame 105 is fixed. The hollow frame 105 is threadedly connected to the first threaded rod 106. On the outer side walls of the first threaded rod 106 and the connecting column 107, a first spring 202 is provided. The top end of the first spring 202 contacts the bottom surface of the hollow frame 105. The bottom end of the first spring 202 contacts the top surface of the frame 200.

[0034] By providing the first spring 202, when the hollow frame 105 moves downward, it can push the first spring 202, and further the first spring 202 can push the frame 200 to move.

[0035] Further, as Figure 4As shown, a fixed plate 500 is fixed to the bottom of one side surface of the limit frame 301. Limit blocks 501 are respectively fixed to opposite sides of the fixed plate 500. Two limit rods 502 are fixed to one side surface of the top surface of the bottom plate 102. The limit blocks 501 are movably connected to the outer side walls of the corresponding limit rods 502.

[0036] By providing the limit blocks 501 and the limit rods 502, the position of the fixed plate 500 can be limited, thereby facilitating the second threaded rod 700 to drive the limit frame 301 to move.

[0037] Furthermore, as Figure 4 shown, fixed blocks 400 are respectively fixed to the bottoms of opposite side surfaces of the outer side wall of the C-shaped frame 302. A second spring 401 is fixed between the side surface of the fixed block 400 and the side surface of the limit frame 301 that are close to each other.

[0038] By providing the second spring 401, when the docking rod 603 is in the first docking groove 601, the toothed plate 300 is separated from the toothed block 303, and at this time the second spring 401 is stretched.

[0039] This solution has the following working process: When pressing the nylon plate part, first place the nylon plate part on the surface of the moving plate of the vertical lathe. At this time, the turning tool of the vertical lathe corresponds to the nylon plate part. By manually pulling the pull bar 605, the movement of the pull bar 605 drives the movement of the docking rod 603, and then drives the movement of the connecting rope 606. The movement of the connecting rope 606 drives the movement of the C-shaped frame 302, causing the tooth block 303 to separate from the tooth plate 300. At this time, the docking rod 603 moves out of the second docking groove 602. Then rotate the pull bar 605 so that the docking rod 603 is engaged in the first docking groove 601. At this time, the tooth block 303 and the tooth plate 300 are still in a separated state. After the tooth plate 300 and the tooth block 303 are separated, the frame 200 moves downward, so that the nylon pressing wheel 201 contacts the surface of the nylon plate part. Then manually rotate the first handwheel 203. The rotation of the first handwheel 203 drives the rotation of the first threaded rod 106. The rotation of the first threaded rod 106 drives the downward movement of the driving plate 104. The downward movement of the driving plate 104 pushes the first spring 202, so that the nylon pressing wheel 201 tightly contacts the surface of the nylon plate part under the thrust of the first spring 202. Start the turning tool of the vertical lathe, and the turning tool turns the surface of the nylon plate part. During this process, the first spring 202 always pushes the nylon pressing wheel 201 to squeeze against the surface of the nylon plate part. When the turning is completed, rotate the first handwheel 203 in the reverse direction to reset the first spring 202. Then rotate the second handwheel 701. The rotation of the second handwheel 701 drives the rotation of the second threaded rod 700, and then the limiting frame 301 moves downward to a suitable position. At this time, the tooth block 303 corresponds to the tooth plate 300. Pull the pull bar 605 and rotate it so that the docking rod 603 is engaged in the second docking groove 602. At this time, the second spring 401 pulls the fixed block 400, causing the tooth block 303 and the tooth plate 300 to be re-engaged. Then rotate the second handwheel 701 to move the limiting frame 301 upward. The upward movement of the limiting frame 301 drives the upward movement of the frame 200, so that the nylon pressing wheel 201 is reset.

[0040] According to the above working process, it can be seen that: By setting the tooth plate 300 and the tooth block 303, the position of the frame 200 can be fixed. By setting the positioning column 600, the first docking groove 601, the second docking groove 602, the docking rod 603 and the connecting rope 606, the tooth block 303 can be separated from or engaged with the tooth plate 300. By setting the second threaded rod 700, the limiting frame 301 can move upward, and then drive the frame 200 to move upward, so that the frame 200 can be easily driven to move upward, and then the nylon pressing wheel 201 can move upward, which is convenient for the nylon pressing wheel 201 to be conveniently above the next nylon pressing wheel 201, saving manpower.

[0041] Through the arranged first threaded rod 106, driving plate 104, and hollow frame 105, the driving plate 104 and the hollow frame 105 can move downward. Through the arranged first spring 202, the frame 200 can be pushed by the first spring 202, so that the nylon pressing wheel 201 is extruded and fixed on the surface of the nylon plate part, thereby enabling the nylon plate part to be extruded and positioned, and increasing the turning precision of the nylon plate part.

[0042] Furthermore, as Figure 5 shown, one side of the top surface of the fixed plate 500 is fixed with a positioning post 600. One end of the positioning post 600 is provided with a first docking groove 601, and one end of the positioning post 600 is provided with a second docking groove 602. The first docking groove 601 and the second docking groove 602 are cross-distributed. A docking rod 603 is engaged in the second docking groove 602. One side surface of the docking rod 603 is fixed with a mounting post 604, and one end of the mounting post 604 is fixed with a pulling bar 605. One end of the connecting rope 606 is fixed to the C-shaped frame 302 near the positioning post 600, and one end of the connecting rope 606 movably passes through the positioning post 600 and is fixed to the other side surface of the docking rod 603.

[0043] Through the arranged first docking groove 601, second docking groove 602, and docking rod 603, the position of the C-shaped frame 302 is convenient to be fixed, thereby facilitating the control of the separation or engagement of the tooth block 303 and the tooth plate 300.

[0044] Furthermore, as Figure 4 shown, engaging grooves 304 are respectively formed on opposite side surfaces of the outer side wall of the C-shaped frame 302, and engaging strips 305 are respectively fixed on one side surface of the inner side wall of the limiting frame 301 close to each other. The engaging strips 305 are correspondingly engaged in the engaging grooves 304.

[0045] Through the arranged engaging grooves 304 and engaging strips 305, the position of the C-shaped frame 302 can be limited.

[0046] Furthermore, as Figure 2 shown, a mounting plate 204 is fixed on the top surface of the top plate 100.

[0047] Through the arranged mounting plate 204, the whole device can be fixed to the frame of the vertical lathe.

[0048] In summary, when pressing the nylon plate part, first place the nylon plate part on the surface of the moving plate of the vertical lathe. At this time, the turning tool of the vertical lathe corresponds to the nylon plate part. Manually pull the pulling bar 605. The movement of the pulling bar 605 drives the movement of the docking rod 603, and then drives the movement of the connecting rope 606. The movement of the connecting rope 606 drives the movement of the C-shaped frame 302, so that the tooth block 303 is separated from the tooth plate 300. At this time, the docking rod 603 moves out of the second docking groove 602. Then rotate the pulling bar 605 so that the docking rod 603 is engaged in the first docking groove 601. At this time, the tooth block 303 and the tooth plate 300 are still in a separated state. After the tooth plate 300 and the tooth block 303 are separated, the frame 200 moves downward so that the nylon pressing wheel 201 contacts the surface of the nylon plate part. Then manually rotate the first handwheel 203. The rotation of the first handwheel 203 drives the rotation of the first threaded rod 106. The rotation of the first threaded rod 106 drives the downward movement of the driving plate 104. The downward movement of the driving plate 104 pushes the first spring 202, so that the nylon pressing wheel 201 tightly contacts the surface of the nylon plate part under the thrust of the first spring 202. Start the turning tool of the vertical lathe, and the turning tool turns the surface of the nylon plate part. During this process, the first spring 202 always pushes the nylon pressing wheel 201 to squeeze against the surface of the nylon plate part. When the turning is completed, rotate the first handwheel 203 in the reverse direction to reset the first spring 202. Then rotate the second handwheel 701. The rotation of the second handwheel 701 drives the rotation of the second threaded rod 700, and then the limiting frame 301 moves downward to a suitable position. At this time, the tooth block 303 corresponds to the tooth plate 300. Pull the pulling bar 605 and rotate it so that the docking rod 603 is engaged in the second docking groove 602. At this time, the second spring 401 pulls the fixed block 400, so that the tooth block 303 and the tooth plate 300 are re-engaged. Then rotate the second handwheel 701 so that the limiting frame 301 moves upward. The upward movement of the limiting frame 301 drives the upward movement of the frame 200, so that the nylon pressing wheel 201 is reset.
