[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-Figure 6 , the utility model provides a technical solution:
[0028] See also Figure 1-Figure 7 As shown, a composite structure drawing wheel includes a workpiece 1, a drawing wheel 3 and a core 4, and limit assemblies 2 are arranged on both sides of the core 4. The limit assemblies 2 include an L-shaped plug rod 201 slidably connected to the core 4, and a connecting rod 202 is arranged below the L-shaped plug rod 201. A support rod 203 is fixedly installed on the bottom end of the connecting rod 202, and a fixing rod 204 is fixedly installed on the outer wall of the connecting rod 202. A pressure plate 205 is arranged on one side of the fixing rod 204, and the pressure plate 205 is located at one end of the fixing rod 204 away from the connecting rod 202, and the workpiece 1 is located between the two pressure plates 205.
[0029] When the workpiece 1 is polished, wire-drawn and surface treated, a worker needs to hold an electric drill, and then the driving end of the electric drill will be inserted into the core 4, and the wire drawing wheel 3 driven by the electric drill will move back and forth along the surface of the workpiece 1 to achieve polishing, wire drawing and treatment of the surface of the workpiece 1. When the wire drawing wheel 3 moves along the workpiece 1, the L-shaped plug rod 201 and the connecting rod 202 will move together. During this process, the pressing plate 205 will slide along the outer wall of the workpiece 1, and the pressing plate 205 will move together with the connecting rod 202 through the fixing rod 204, and the support rod 203 will move with the connecting rod 202 and hook the bottom of the workpiece 1, so that the wire drawing wheel 3 will not tilt, so that the wire drawing wheel 3 can only move horizontally;
[0030] The contact between the pressure plate 205 and the workpiece 1 supports the wire drawing wheel 3 on the top of the workpiece 1. The worker only needs to hold the electric drill and push it without adjusting the moving direction of the wire drawing wheel 3. The connection between the pressure plate 205 and the outer wall of the workpiece 1 prevents the wire drawing wheel 3 from tilting. The pressure plate 205 and the support rod 203 only need to move along the workpiece 1 to drive the wire drawing wheel 3 to polish and draw along the surface of the workpiece 1. The worker does not need to pay attention to the direction of the wire drawing wheel 3 at all times, so that the wire drawing wheel 3 can maintain a constant vertical or horizontal movement state.
[0031] See also Figure 6 Two support rods 17 are fixedly installed on the outer wall of the fixed rod 204, a sliding rod 18 is fixedly installed on the outer wall of the support rod 17, a sliding cylinder 21 is fixedly installed on the outer wall of the pressure plate 205, the sliding rod 18 is slidably connected to the inner wall of the sliding cylinder 21, a tension spring 19 is connected between the pressure plate 205 and the support rod 17, and the sliding rod 18 and the sliding cylinder 21 are both located inside the tension spring 19.
[0032] The tension spring 19 makes the distance between the pressure plate 205 and the fixed rod 204 adjustable, so that the pressure plate 205 can clamp workpieces 1 of different widths, thereby improving the applicability of the pressure plate 205. When the pressure plate 205 squeezes the tension spring 19 as the width of the workpiece 1 increases, the slide bar 18 will slide along the inner wall of the slide cylinder 21. The sliding effect of the slide cylinder 21 and the sleeve 8 allows the L-shaped insert rod 201 to maintain vertical movement to prevent the pressure plate 205 from tilting and shifting, so that the pressure plate 205 can be more stably connected to the workpiece 1.
[0033] See also Figure 5 and Figure 7 The outer wall of the pressure plate 205 is rotatably connected with a plurality of balls 206, and the balls 206 are located on the side of the pressure plate 205 corresponding to the workpiece 1. The balls 206 are slidably connected to the outer wall of the workpiece 1, and circular grooves 20 are provided at both ends of the core 4. One end of the L-shaped rod 201 is located inside the circular groove 20 and is slidably connected to the circular groove 20.
[0034] The ball 206 is in direct contact with the outer wall of the workpiece 1, reducing the friction caused by the direct contact between the outer wall of the pressure plate 205 and the outer wall of the workpiece 1, so as to prevent the pressure plate 205 from being worn due to friction when moving along the outer wall of the workpiece 1. The circular groove 20 provides a space for the L-shaped rod 201 to be inserted. When the core 4 and the drawing wheel 3 rotate, the L-shaped rod 201 will slide along the inner wall of the circular groove 20, so that the L-shaped rod 201 will not rotate with the drawing wheel 3 and the core 4.
[0035] See also Figure 1 and Figure 4 A U-shaped fixing block 5 is fixedly installed on one end of the support rod 203 away from the connecting rod 202, a rotating rod 6 is fixedly installed on the inner wall of the U-shaped fixing block 5, and a roller 7 is rotatably connected to the outer wall of the rotating rod 6, and the outer wall of the roller 7 is against the inner bottom wall of the workpiece 1.
[0036] The direct contact between the support rod 203 and the bottom of the workpiece 1 will also generate friction on the surface of the workpiece 1. In order to avoid wear on the workpiece 1, the roller 7 is used to slide along the bottom of the workpiece 1, which can not only hook the bottom of the workpiece 1, but also slide along the bottom of the workpiece 1 through the roller 7. The outer wall of the roller 7 is against the bottom of the workpiece 1, so that the workpiece 1 is clamped between the drawing wheel 3 and the roller 7, preventing the drawing wheel 3 from falling or loosening.
[0037] See also Figure 2 A rack 13 is fixedly mounted on one end of the L-shaped insertion rod 201 and the connecting rod 202 , a gear 11 is meshedly connected between the two racks 13 , and a mounting rod 12 is fixedly mounted on the outer wall of the gear 11 .
[0038] The gear 11 can be driven to rotate by twisting the mounting rod 12. After the gear 11 rotates, the two racks 13 will separate or move relative to each other. After the rack 13 moves, it will respectively drive the L-shaped rod 201 and the connecting rod 202 to separate or move relative to each other, thereby adjusting the distance between the L-shaped rod 201 and the connecting rod 202. The adjustment of the distance between the connecting rod 202 and the L-shaped rod 201 allows the support rod 203 to be adjusted according to the height of the workpiece 1, so that the support rod 203 can always hook the bottom of different workpieces 1, ensuring the constant vertical or horizontal movement state of the drawing wheel 3.
[0039] See also Figure 1-Figure 7 A sleeve 8 is provided between the L-shaped insert rod 201 and the connecting rod 202 . One end of the L-shaped insert rod 201 and the connecting rod 202 are both located inside the sleeve 8 and are slidably connected to the inner wall of the sleeve 8 .
[0040] The sleeve 8 is used to connect the L-shaped rod 201 and the connecting rod 202 together, so that the L-shaped rod 201 and the connecting rod 202 can slide along the inner wall of the sleeve 8 when they are separated or move relative to each other, making the L-shaped rod 201 and the connecting rod 202 more stable when moving.
[0041] See also Figure 2-Figure 3 A rotating shaft 10 is fixedly installed on the inner wall of the sleeve 8, and the end of the rotating shaft 10 away from the sleeve 8 is rotatably connected to the gear 11. A knob 9 is fixedly installed on the end of the mounting rod 12 away from the gear 11, and the outer wall of the mounting rod 12 is rotatably connected to the sleeve 8, and the knob 9 is located outside the sleeve 8.
[0042] The rotating shaft 10 supports the gear 11 inside the sleeve 8 and allows the gear 11 to rotate. The mounting rod 12 can be driven to rotate by turning the knob 9, so that the mounting rod 12 is easier to control.
[0043] See also Figure 3 An iron block 14 is fixedly mounted on the outer wall of the knob 9, a return spring 15 is fixedly mounted on the outer wall of the sleeve 8, the iron block 14 is magnetically attracted with a magnet 16, and one end of the return spring 15 away from the sleeve 8 is fixedly connected to the outer wall of the magnet 16.
[0044] When the iron block 14 and the magnet 16 are magnetically attracted to each other, the knob 9 cannot be rotated, which means that the L-shaped rod 201 and the connecting rod 202 cannot be moved at this time. The elasticity of the reset spring 15 is relatively large, so it will not be easily deformed. When it is necessary to turn the knob 9, the magnet 16 is pushed away from one side of the iron block 14 to release the magnetic attraction between the iron block 14 and the magnet 16. At this time, the knob 9 can be turned to move.
[0045] Working principle:
[0046] When the workpiece 1 is polished, wire-drawn and surface treated, a worker needs to hold an electric drill, and then the driving end of the electric drill will be inserted into the core 4, and the wire drawing wheel 3 driven by the electric drill will move back and forth along the surface of the workpiece 1 to achieve polishing, wire drawing and treatment of the surface of the workpiece 1. When the wire drawing wheel 3 moves along the workpiece 1, the L-shaped plug rod 201 and the connecting rod 202 will move together. During this process, the pressing plate 205 will slide along the outer wall of the workpiece 1, and the pressing plate 205 will move together with the connecting rod 202 through the fixing rod 204, and the support rod 203 will move with the connecting rod 202 and hook the bottom of the workpiece 1, so that the wire drawing wheel 3 will not tilt, so that the wire drawing wheel 3 can only move horizontally;
[0047] The contact between the pressure plate 205 and the workpiece 1 supports the wire drawing wheel 3 on the top of the workpiece 1. The worker only needs to hold the electric drill and push it without adjusting the moving direction of the wire drawing wheel 3. The connection between the pressure plate 205 and the outer wall of the workpiece 1 prevents the wire drawing wheel 3 from tilting. The pressure plate 205 and the support rod 203 only need to move along the workpiece 1 to drive the wire drawing wheel 3 to polish and draw along the surface of the workpiece 1. The worker does not need to pay attention to the direction of the wire drawing wheel 3 at all times, so that the wire drawing wheel 3 can maintain a constant vertical or horizontal movement state.
[0048] The gear 11 can be driven to rotate by twisting the mounting rod 12. After the gear 11 rotates, the two racks 13 will separate or move relative to each other. After the rack 13 moves, it will respectively drive the L-shaped rod 201 and the connecting rod 202 to separate or move relative to each other, thereby adjusting the distance between the L-shaped rod 201 and the connecting rod 202. The adjustment of the distance between the connecting rod 202 and the L-shaped rod 201 allows the support rod 203 to be adjusted according to the height of the workpiece 1, so that the support rod 203 can always hook the bottom of different workpieces 1, ensuring the constant vertical or horizontal movement state of the drawing wheel 3.
