Description

Technical Field

[0001] This invention relates to the field of handle processing technology, and more specifically, to a tooling for grinding and machining the arc of an automotive gear shift handle. Background Technology

[0002] Because the gear shift lever is injection molded by two molds during the production process, waste material will be generated in the part where the two molds meet. That is, excess waste material will be generated at the outer edge of the lever. To improve the feel, the lever needs to be further processed and polished.

[0003] The existing handle has a structure with a round top and a conical bottom, and is fixedly connected to a stop bar. When grinding the rounded shape of the handle, the stop bar is inserted into the handle, and the handle is held so that the outer edge of the waste material comes into contact with the grinding belt for grinding. However, when grinding the waste material on the conical bottom edge, the rotation angle of the stop bar is restricted by the grinding belt, causing a gap between the conical bottom edge of the handle and the grinding belt, preventing a tight fit. This results in incomplete grinding of the waste material on the outer edge of the handle, affecting the grinding quality and effect. Summary of the Invention

[0004] This invention provides a grinding fixture for machining the arc of an automotive gear shift lever. It utilizes a rotating support wheel to press the grinding belt firmly against the area to be ground, thereby solving the problem mentioned in the background art: a gap exists between the bottom conical outer edge of the lever and the grinding belt, preventing a tight fit.

[0005] To achieve the above objectives, a grinding arc machining fixture for an automotive gear shift lever includes a support plate, a bracket plate, a side plate fixedly mounted on the support plate, and a support stop bar located on the bracket plate for fixing the lever. A grinding strip is provided on the side plate, forming a grinding area at the tapered outer edge of the lever. Two sets of adjustment mechanisms are arranged vertically on the inner side of the side plate. The upper adjustment mechanism is located outside the grinding strip, and the lower adjustment mechanism is located inside the grinding strip. The grinding area is located between the upper and lower adjustment mechanisms, so that the angle of the grinding strip on one side of the grinding area can be adjusted by lateral movement, so that the angle of the grinding strip in that area matches the angle of the grinding area.

[0006] When processing waste material in the grinding area, a support mechanism located inside the handle is also provided on the side plate between the upper and lower adjustment mechanisms. The support mechanism rotates and rolls along the grinding belt close to the grinding area to drive the grinding belt to contact the waste material in the grinding area.

[0007] The adjustment mechanism includes a roller that fits against the grinding belt and a first arched frame that rotates with the roller. The upper roller is located outside the grinding belt, and the lower roller is located inside the grinding belt. The upper roller is horizontally higher than the arc connection between the area to be ground and the handle, and the lower roller is lower than the area to be ground.

[0008] One end of the first arched frame is fixedly provided with the telescopic end of a cylinder, and the cylinder is fixedly provided with the side plate.

[0009] Under normal conditions, an inward-shrinking zone is formed between the area to be polished and the polishing belt, which is used to receive the outward-extending polishing belt.

[0010] When grinding waste material in the area to be ground, the upper roller retracts inward and the lower roller extends outward to stretch the grinding belt between the upper and lower rollers into an inclined shape, thereby reducing the distance between the grinding belt and the area to be ground.

[0011] The support mechanism includes a bearing wheel located between the upper and lower rollers and in contact with the inner side of the grinding belt. The bearing wheel is close to the area to be ground in the horizontal direction and pushes the inclined grinding belt toward the area to be ground by lateral movement, so as to achieve contact between the grinding belt and the area to be ground.

[0012] The length of the load-bearing wheel is less than the length of the roller.

[0013] A second arched frame is rotatably mounted on the bearing wheel. A sliding rod is fixedly mounted on one end of the second arched frame. A retaining ring is slidably mounted on the sliding rod. A drive shaft of a drive motor is fixedly mounted on the retaining ring. The drive motor is fixed on the bracket, and the bracket is fixed to the side plate.

[0014] An outer baffle is fixedly installed at one end of the slide rod away from the second arched frame. A compression spring is sleeved on the slide rod between the outer baffle and the retaining ring. Under normal conditions, the compression spring is in a stretched state and connects the retaining ring and the outer baffle.

[0015] An electromagnet is fixedly installed on the retaining ring, and a slide rod passes through the electromagnet. An inner baffle is fixedly installed on the slide rod located on one side of the electromagnet.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In this automotive gear shift lever grinding arc machining fixture, the upper and lower rollers move in opposite directions to adjust the tilt angle of the grinding belt, so that the tilt angle of the grinding belt is close to that of the area to be ground. Then, the bearing wheel rotates to press the grinding belt against the area to be ground, thereby realizing the treatment of waste material in the area to be ground and improving the grinding effect.

[0029] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0030] To address the issue of a gap between the tapered outer edge of the gear shift lever and the grinding belt, preventing a tight fit, this invention provides a grinding fixture for the arc-shaped gear shift lever in automobiles. (Refer to...) Figures 1-2 As shown, the device includes a support plate 100, a bracket plate 101, a side plate 102 fixedly mounted to the support plate 100, and a support stop bar 103 located on the bracket plate 101 for fixing the handle 104. A grinding mechanism is provided on the side plate 102, wherein the grinding mechanism includes a grinding belt 105 and a power unit (e.g., a motor) for driving the grinding belt 105 to rotate. A grinding area 131 is formed at the tapered outer edge of the handle 104 (see reference). Figure 6 As shown, the area to be polished 131 is the region a1-a2. When polishing the handle 104, first fix the handle 104 to the support rod 103, so that the handle 104 is in a certain position. Figure 4In the state shown, the power unit is then activated to drive the grinding belt 105 to rotate, so that the waste material on the outer edge of the conical part of the handle 104 can be ground. The specific process is as follows:

[0031] First, combined Figure 3 , Figure 4 As shown, there are two sets of adjustment mechanisms 110 arranged vertically on the inner side of the side plate 102. The upper adjustment mechanism 110 is located outside the grinding belt 105, and the lower adjustment mechanism 110 is located inside the grinding belt 105. The area to be ground 131 is located between the upper and lower adjustment mechanisms 110. The angle of the grinding belt 105 on one side of the area to be ground 131 can be adjusted by lateral movement, so that the angle of the grinding belt 105 in this area matches the angle of the area to be ground 131. In addition, when the waste material in the area to be ground 131 is processed, a support mechanism 120 located inside the handle 104 is also provided on the side plate 102 between the upper and lower adjustment mechanisms 110. The support mechanism 120 rotates and rolls along the grinding belt 105 close to the area to be ground 131 to drive the grinding belt 105 to contact the waste material in the area to be ground 131.

[0032] Then, the adjusting mechanism 110 includes a roller 111 that fits against the polishing belt 105, and a first arched frame 112 that is rotatably configured with the roller 111, wherein the upper roller 111 is located outside the polishing belt 105, and the lower roller 111 is located inside the polishing belt 105, that is... Figure 4 As shown in the diagram, the upper roller 111 is horizontally lower than the arc connection between the area to be polished 131 and the handle 104, while the lower roller 111 is lower than the area to be polished 131.

[0033] On the other hand, one end of the first arched frame 112 is fixedly provided with the telescopic end of the cylinder 113, and the cylinder 113 is fixedly provided with the side plate 102; the cylinder 113 serves as a power source to provide driving force for the movement of the roller 111; before grinding the waste material in the grinding area 131, the roller 111 is pushed out and retracted by the telescopic movement of the telescopic end of the cylinder 113. For the upper roller 111, the cylinder 113 pulls the roller 111 inward, causing the roller 111 to drive the grinding belt 105 to bend inward; for the lower roller 111, the cylinder 113 pushes the roller 111 outward, causing the roller 111 to drive the grinding belt 105 to bend inward and outward.

[0034] That is, when grinding the waste material in the area to be ground 131, the upper roller 111 retracts inward and the lower roller 111 extends outward, so as to stretch the grinding belt 105 between the upper and lower rollers 111 into an inclined shape, thereby reducing the distance between the grinding belt 105 and the area to be ground 131; that is, the upper and lower rollers 111 move in opposite directions, causing the grinding belt 105 between the upper and lower rollers 111 to gradually tilt, forming Figure 6As shown, this allows for adjustment of the 105-degree tilt angle of the grinding belt.

[0035] When the grinding belt is 105 Figure 4 In the normal operating state, the polishing belt 105 is in a relatively natural and relaxed state, the upper and lower rollers 111 are in the initial set position, and a certain distance is maintained between the polishing belt 105 and the area to be polished 131. This not only provides space for subsequent adjustments based on the angle of the area to be polished 131, but also avoids unnecessary friction and wear between the polishing belt 105 and the handle 104 when not polishing, thus extending the service life of the polishing belt 105.

[0036] Secondly, under normal conditions, an inward-shrinking area 130 is formed between the area to be polished 131 and the polishing belt 105. During the above process, that is, during the tilting of the polishing belt 105, the polishing belt 105 moves towards the inward-shrinking area 130. The inward-shrinking area 130 is used to receive the outwardly extending polishing belt 105, thereby reducing the area of ​​the inward-shrinking area 130, so that the polishing belt 105 is close to the area to be polished 131, and the tilted polishing belt 105 is adapted to the area to be polished 131, so as to polish the waste in the area to be polished 131.

[0037] refer to Figure 4 As shown, the support mechanism 120 includes a bearing wheel 121 located between the upper and lower rollers 111 and in contact with the inner side of the polishing belt 105. The bearing wheel 121 is close to the polishing area 131 in the horizontal direction and pushes the inclined polishing belt 105 towards the polishing area 131 by lateral movement, so as to achieve contact between the polishing belt 105 and the polishing area 131. After the upper and lower rollers 111 stretch the polishing belt 105 between them to form an inclined shape, the bearing wheel 121 pushes the inclined polishing belt 105 towards the polishing area 131 by lateral movement, so that the polishing belt 105, which was originally a certain distance from the polishing area 131, can come close to it, which is a necessary condition for subsequent polishing.

[0038] It is worth noting that the length of the bearing wheel 121 is less than the length of the roller 111. This reduces the contact area between the bearing wheel 121 and the grinding belt 105, resulting in less friction between them and reducing the impact on the rotation of the grinding belt 105.

[0039] Combination Figure 5As shown, a second arched frame 122 is rotatably mounted on the bearing wheel 121. A slide rod 123 is fixedly mounted at one end of the second arched frame 122. A retaining ring 125 is slidably mounted on the slide rod 123. A drive shaft of a drive motor 129 is fixedly mounted on the retaining ring 125. The drive motor 129 is fixed on the bracket, and the bracket is fixed to the side plate 102. Thus, the retaining ring 125 can move relative to the slide rod 123. In the initial state, during the process of pushing the grinding belt 105 outward, the drive motor 129 drives the retaining ring 125 to rotate clockwise through the drive shaft. At the same time, the slide rod 123, the bearing wheel 121, and the retaining ring 125 rotate synchronously, so that the grinding belt 105 is pushed outward by the rotation of the bearing wheel 121, so that the waste material of a1-a2 (that is, the waste material in the grinding area 131) is carried away by the grinding belt 105.

[0040] Furthermore, an outer baffle 124 is fixedly installed at one end of the slide rod 123 away from the second arched frame 122. A compression spring 126 is sleeved on the slide rod 123 between the outer baffle 124 and the retaining ring 125. Under normal conditions, the compression spring 126 is in a stretched state and connects the retaining ring 125 to the outer baffle 124. In addition, an electromagnet 127 is fixedly installed on the retaining ring 125. The slide rod 123 passes through the electromagnet 127. An inner baffle 128 is fixedly installed on the slide rod 123 on one side of the electromagnet 127.

[0041] Working principle: In the initial state, the electromagnet 127 is energized and attracts the inner baffle 128. At this time, the bearing wheel 121 is close to but not in contact with the grinding belt 105, and the compression spring 126 is in the extended state. When the grinding belt 105 is adjusted to the inclined state, the electromagnet 127 is de-energized and the inner baffle 128 is released. Under the elastic action of the compression spring 126, the outer baffle 124 is pulled closer to the retaining ring 125. During this process, the bearing wheel 121 applies pressure to the inclined grinding belt 105, forcing the grinding belt 105 to extend outward and contact the waste in the grinding area 131. Then, the rotating grinding belt 105 carries away the waste in the grinding area 131.

[0042] At the same time, the bearing wheel 121 rotates clockwise around the drive shaft and rolls on the grinding belt 105, so that the grinding belt 105 is pressed against and comes into contact with the waste material in the area to be ground 131 along the rolling path of the bearing wheel 121, thereby grinding the waste material in the area.

[0043] In other words, by using the upper and lower rollers 111 to move in opposite directions, the tilt angle of the grinding belt 105 is adjusted so that the grinding belt 105 is close to the tilt angle of the area to be ground 131. Then, the bearing wheel 121 is rotated to press the grinding belt 105 against the area to be ground 131, thereby realizing the treatment of waste material in the area to be ground 131 and improving the grinding effect.

[0044] After polishing is completed, the inner baffle 128 is manually reversed and moved closer to the electromagnet 127. Then, the electromagnet 127 is energized and attracts the inner baffle 128 a second time. Then, the next handle 104 is polished.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
