Description

Technical Field

[0001] This utility model relates to the field of wheel rim processing technology, and in particular to a positioning fixture for forklift wheel rim production. Background Technology

[0002] A wheel rim, also known as a wheel hub, is a component that mounts and supports the tire around the wheel. Wheel rims can be integral, permanently connected, or detachable. Positioning fixtures are mainly used to position and clamp the wheel rims to prevent them from shifting during the manufacturing process, which could lead to problems with the produced wheel rims. They can also ensure the precision and consistency of wheel rim manufacturing.

[0003] In the prior art, such as Chinese Patent No. CN219901851U, a positioning fixture for forklift wheel rim production, which relates to the field of positioning fixture technology, a support structure is included. A limiting structure is inserted into the inner wall of the support structure, and a telescopic structure is inserted into one side of the support structure. After processing, the rebound force of the fourth spring can raise the receiving plate, thereby lifting the processed wheel rim and improving work efficiency. Rotating the handle rotates the auger inside the stationary tube, indirectly moving the connecting tube forward, which in turn moves the connecting plate forward, improving material clamping. When the auger is rotated by the handle, the connecting tube sleeved on the outer wall of the locking block prevents the connecting plate from rotating with it, indirectly achieving the clamping head's clamping function on the wheel rim.

[0004] While the above solution has the advantages mentioned above, its disadvantages are as follows: after the rim is clamped and fixed from the side, the rim is prone to shifting upwards during high-speed machining. There is no positioning mechanism above the rim, which can cause the rim to loosen, posing a certain safety hazard. Moreover, when the direction of the rim needs to be adjusted, it needs to be repositioned, which greatly reduces the efficiency of rim machining. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where, after the rim is clamped and fixed from the side, the rim is prone to shifting upwards during high-speed processing. The rim lacks a positioning mechanism, which causes it to loosen, posing a certain safety hazard. Furthermore, when the rim needs to be adjusted, it needs to be repositioned, which greatly reduces the efficiency of rim processing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a positioning fixture for forklift wheel rim production, comprising: a base, and further comprising: A positioning component is disposed on the outer surface of the base, the positioning component comprising: A placement plate is movably disposed at the top center of the base, and a sliding groove is provided at the top center of the placement plate; A bidirectional screw is movably mounted in the groove. An adjustment component is disposed on the outer surface of the base.

[0007] Preferably, the positioning component further includes: Two sliders are movably mounted on the outer surface of the bidirectional screw, and an arc-shaped clamp is fixedly mounted on the top of the sliders; The slider can slide laterally inside the groove; An L-shaped plate is fixedly installed at the center of one side of the top of the base, and an electric push rod is fixedly installed on the top of the L-shaped plate; The output end of the electric actuator passes through the L-shaped plate.

[0008] The technical effect of adopting the above-mentioned further solution is that: by rotating the double-acting screw through the turntable, the double-acting screw drives the arc-shaped clamping plate through the slider to clamp and position the wheel rim, so that the wheel rim is positioned on the placement plate. When the two sliders move relative to each other or in opposite directions, they can drive the telescopic sleeve to extend and retract. The telescopic sleeve can protect the double-acting screw and prevent falling debris from affecting the rotation of the double-acting screw.

[0009] Preferably, the adjustment component includes: A rectangular groove is formed at the center of one side of the base, and a drive motor is fixedly installed at the center of the interior of the rectangular groove. A connecting shaft is fixedly installed at the output end of the drive motor, and the connecting shaft passes through the base and connects to the placement plate; An annular groove is formed at the top center of the base; The annular groove is concentric with the drive motor and the electric push rod. Two arc-shaped support plates are fixedly installed on both sides of the bottom of the placement plate, and the arc-shaped support plates are movably installed inside the annular groove.

[0010] The technical effect of adopting the above-mentioned further solution is that: when the drive motor is turned on, it drives the placement plate to rotate through the connecting shaft. The rotation of the placement plate can drive the positioned rim to be adjusted, making it easier to process different positions of the rim. When the placement plate rotates, it drives the arc-shaped support plate to rotate inside the annular groove. The arc-shaped support plate can improve the stability of the placement plate when it rotates.

[0011] Preferably, the output end of the electric push rod is fixedly provided with a bushing, and a rotating shaft is movably provided inside the bushing.

[0012] The technical effect of adopting the above-mentioned further solution is that the rotating shaft can rotate inside the bushing, so when the placement plate drives the wheel rim to rotate, the positioning disc also rotates accordingly.

[0013] Preferably, a positioning disc is fixedly provided at the bottom of the rotating shaft.

[0014] The technical effect of adopting the above-mentioned further solution is that the positioning disc moves down to position the upper end of the rim, preventing the rim from moving up during processing, affecting the processing effect, and causing danger.

[0015] Preferably, one end of the bidirectional screw passes through the slide groove, and a turntable is fixedly provided at one end of the bidirectional screw.

[0016] The technical effect of adopting the above-mentioned further solution is that the bidirectional screw is rotated by a turntable.

[0017] Preferably, the opposing surfaces of the two sliders are fixedly provided with telescopic sleeves, which are movably disposed on the outer surface of the bidirectional screw.

[0018] The technical effect of adopting the above-mentioned further solution is that when the two sliders move relative to each other or in opposite directions, they can drive the telescopic sleeve to extend and retract. The telescopic sleeve can protect the bidirectional screw and prevent falling debris from affecting the rotation of the bidirectional screw.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the wheel rim to be processed is placed on a placement plate. A double-acting screw is rotated by a turntable. The double-acting screw drives an arc-shaped clamping plate through a slider to clamp and position the wheel rim on the placement plate. When the two sliders move relative to each other or away from each other, they can drive the telescopic sleeve to extend and retract. The telescopic sleeve can protect the double-acting screw and prevent falling debris from affecting its rotation. Then, the electric push rod is activated to drive the bushing, rotating shaft, and positioning disc to move down and position the upper end of the wheel rim, making it more stably positioned on the placement plate. The rotating shaft can rotate inside the bushing. Therefore, when the placement plate drives the wheel rim to rotate, the positioning disc also rotates, positioning the upper end of the wheel rim and preventing the wheel rim from moving upward.

[0020] 2. In this utility model, the drive motor drives the placement plate to rotate through the connecting shaft. The rotation of the placement plate can adjust the positioned rim, making it easier to process different positions of the rim. When the placement plate rotates, it drives the arc-shaped support plate to rotate inside the annular groove. The arc-shaped support plate can improve the stability of the placement plate when it rotates, and can also improve the load-bearing capacity of the placement plate, so as to better position and process the rim and improve the processing effect.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figure 1-4 As shown, this utility model provides a positioning fixture for forklift wheel rim production, including: a base 1, a positioning component, and an adjustment component; The positioning component includes: a placement plate 102 is movably installed at the top center of the base 1, a slide groove 103 is provided at the top center of the placement plate 102, a bidirectional screw 104 is movably arranged inside the slide groove 103, and a turntable 106 is fixedly installed on one side of the bidirectional screw 104 through the slide groove 103. Two sliders 117 are movably sleeved on the outer surface of the bidirectional screw 104, and an arc-shaped clamp 107 is fixedly installed on the top of the sliders 117; The turntable 106 drives the bidirectional screw 104 to rotate, and the slider 117 drives the arc-shaped clamp 107 to move relative to or away from each other, which is adjusted according to the size of the wheel rim. An L-shaped plate 108 is fixedly installed at the center of one side of the top of the base 1. An electric push rod 109 is fixedly installed on one side of the top of the L-shaped plate 108. The output end of the electric push rod 109 passes through the L-shaped plate 108. A bushing 110 is fixedly installed on the output end of the electric push rod 109. The internal bearing of the bushing 110 is fitted with a rotating shaft 111, and a positioning disc 112 is fixedly installed at the bottom of the rotating shaft 111. Telescopic sleeves 105 are fixedly installed on the opposite surfaces of the two sliders 117, and the telescopic sleeves 105 are movably sleeved on the outer surface of the bidirectional screw 104.

[0026] In this embodiment, the electric push rod 109 drives the rotating shaft 111 and the positioning disk 112 to move downward through the bushing 110, thereby positioning the upper end of the rim and preventing the rim from moving upward during processing, which would affect the processing effect and cause danger.

[0027] Example 2, as Figure 1-4 As shown, the adjustment assembly includes: a rectangular groove 101 is provided at the center of one side of the base 1, a drive motor 115 is fixedly installed at the center of the rectangular groove 101, a connecting shaft 116 is fixedly installed at the output end of the drive motor 115, and the connecting shaft 116 passes through the base 1 and connects to the placement plate 102. The drive motor 115 can drive the placement plate 102 to rotate through the connecting shaft 116, and the placement plate 102 can be used to adjust the rim for better processing. An annular groove 113 is provided at the top center of the base 1. Two arc-shaped support plates 114 are movably embedded inside the annular groove 113. The arc-shaped support plates 114 are fixedly installed at the bottom of the placement plate 102. The annular groove 113 is concentric with the drive motor 115 and the electric push rod 109.

[0028] In this embodiment, the arc-shaped support plate 114 can improve the stability of the placement plate 102 and can rotate with the placement plate 102 inside the annular groove 113.

[0029] Working principle: The wheel rim to be processed is placed on the placement plate 102. The double-acting screw 104 is rotated by the turntable 106. The double-acting screw 104 drives the arc-shaped clamping plate 107 through the slider 117 to clamp and position the wheel rim on the placement plate 102. When the two sliders 117 move relative to each other or away from each other, they can drive the telescopic sleeve 105 to extend and retract.

Then, the electric push rod 109 is turned on to drive the bushing 110, the rotating shaft 111 and the positioning disc 112 to move down and position the upper end of the wheel rim, making it more stably positioned on the placement plate 102. The rotating shaft 111 can rotate inside the bushing 110. Therefore, when the placement plate 102 drives the wheel rim to rotate, the positioning disc 112 also rotates, positioning the upper end of the wheel rim and preventing the wheel rim from moving up. The drive motor 115 is turned on, which drives the placement plate 102 to rotate through the connecting shaft 116. The rotation of the placement plate 102 can adjust the positioned rim, making it easier to process different positions of the rim.
