Description

Technical Field

[0001] The present invention relates to the technical field of throttle processing, and in particular to a throttle bracket disassembly machine. Background Art

[0002] During the manufacturing process of electric bicycle throttles, defective products are inevitably produced. These defective products need to be disassembled and repaired, which involves separating the throttle bracket and the rotor assembly. Moreover, even for qualified products, when repair is required, the throttle bracket and the rotor assembly must be separated. However, the throttle bracket and the rotor assembly are tightly fitted together, making them difficult to separate. The reason is that there are claws on the throttle bracket and blocks that match the claws on the inner wall of the rotor assembly. During assembly, the throttle bracket is inserted into the rotor assembly, and the inclined surface of the claws undergoes elastic deformation. When the assembly is in place, the claws return to their original state. At this point, the claws and the block have achieved a limit fit, and the entire product cannot be separated, resulting in difficult disassembly.

[0003] Existing disassembly methods typically involve workers forcibly knocking the throttle bracket against a tabletop, causing the internal claws to elastically deform and separate the throttle bracket from the rotor assembly. This method has significant drawbacks. Firstly, the disassembly process relies heavily on the worker's experience, making it difficult. Secondly, forced disassembly can easily damage the product's appearance and break the claws, rendering the throttle bracket useless. This also reduces the lifespan of the repaired product.

[0030] Example 1

[0031] Combined with attachment Figure 1-7, this embodiment proposes a throttle bracket disassembly machine, including a base 100, on which a fixing plate 103, a first driving member 101 and a second driving member 102 are provided; the output end of the second driving member 102 is fixedly connected to a clamping shaft 110, and the clamping shaft 110 passes through the fixing plate 103; a chuck 120 is fixedly provided on the fixing plate 103, and the chuck 120 is sleeved on the outside of the clamping shaft 110, and a clamping nozzle 130 is provided at the end of the clamping shaft 110; the output end of the first driving member 101 is connected to a push plate 104, and the push plate 104 is located on one side of the fixing plate 103. The clamping shaft 110 and the clamping head 120 both pass through the push plate 104; a reducing bevel 111 is provided on the clamping shaft 110, and a reducing adapting bevel 121 is provided on the inner side of the clamping head 120, and the reducing bevel 111 is matched with the reducing adapting bevel 121; a retraction bevel 122 is provided at the end of the clamping head 120, and a retraction matching bevel 131 is provided on the clamping mouth 130, and the retraction matching bevel 122 is matched with the retraction matching bevel 131; a tightening bevel 123 is also provided at the end of the clamping head 120, and the tightening bevel 123 is used to cooperate with the claw 201 in the handle bracket 200.

[0032] The throttle bracket disassembly machine of this embodiment can conveniently and easily separate the throttle bracket 200 and the rotor assembly 202 without damaging the throttle bracket 200 and the rotor assembly 202, thereby improving the product repair efficiency.

[0033] In this embodiment, the first drive member 101 and the second drive member 102 are power mechanisms, which can be selected from pneumatic cylinders, hydraulic cylinders, electric push rods, or lead screws, etc., which can achieve reciprocating linear motion. The first drive member 101 and the second drive member 102 are preferably pneumatic cylinders. The output end of the first drive member 101 can drive the push plate 104 to achieve reciprocating motion, and the output end of the second drive member 102 can drive the clamping shaft 110 to achieve reciprocating motion. In a preferred embodiment, both the push plate 104 and the clamping shaft 110 can achieve horizontal reciprocating motion.

[0034] The present embodiment is a throttle bracket disassembly machine for disassembling the throttle, and further for disassembling the throttle bracket 200 and the rotor assembly 202. Figure 7 It can be seen that there is a claw 201 on the throttle bracket 200, and a block 203 adapted to the claw 201 is provided on the inner wall of the rotor assembly 202. During assembly, the throttle bracket 200 is inserted into the rotor assembly 202, and the claw 201 undergoes elastic deformation. When assembled in place, the claw 201 returns to its original state. At this time, the claw 201 and the block 203 have achieved limited cooperation, and the entire product cannot be separated, resulting in difficulty in disassembly.

[0035] Based on the structure of the throttle, the working method and principle of the throttle bracket disassembly machine of this embodiment are as follows:

[0036] like Figure 5 The operator first puts the handlebar to be disassembled into the structure composed of the chuck 120, the clamping shaft 110 and the clamping nozzle 130, and then starts the second driving member 102. The output end of the second driving member 102 drives the clamping shaft 110 to be pushed out, and the chuck 120 and the fixing plate 103 are fixed to each other. As a result, the clamping shaft 110 and the chuck 120 move relative to each other, and the reducing inclined surface 111 on the clamping shaft 110 and the reducing adapting surface on the chuck 120 slide relative to each other, thereby driving the chuck 120 to deform and expand. Figure 6 The end of the middle clamp 120 is deformed and expanded.

[0037] The chuck 120 keeps expanding, and then the first driving member 101 is started. The output end of the first driving member 101 drives the push plate 104 to move in the direction of the handle to be disassembled, ensuring that the inclined surface of the claw 201 inside the handle bracket 200 gradually approaches the tightening inclined surface 123 until it appears as shown in the figure. Figure 6 In the form of, that is, the inclined surface of the claw 201 inside the throttle bracket 200 abuts against the tightening inclined surface 123. In practice, in three-dimensional space, the claw 201 and the tightening inclined surface 123 form an annular structure arranged circumferentially. That is, at this time, the tightening inclined surface 123 cooperates with the inclined surface of the claw 201, and the tightening inclined surface 123 can apply a tightening force to the inclined surface of the claw 201 away from the inner stopper 203 of the rotor assembly 202.

[0038] When the push plate 104 is pushed out, the output end of the first drive member 101 begins to retract, driving the clamping shaft 110 and the clamping nozzle 130 toward the fixed plate 103. Driven by the second drive member 102, the clamping shaft 110 pulls the clamping nozzle 130 toward the chuck 120, causing the convergence matching bevel 131 on the clamping nozzle 130 to contact the convergence bevel 122 on the chuck 120, and relative movement occurs. Simultaneously, as the clamping shaft 110 pulls the clamping nozzle 130 toward the chuck 120, the reducing bevel 111 and the reducing matching bevel 121 gradually disengage, causing the diameter of the chuck 120 to continuously decrease. The above process causes the tightening inclined surface 123 to apply a tightening force to the inclined surface of the claw 201 away from the stop block 203 in the rotor assembly 202, thereby causing the claw 201 to disengage from the stop block 203. The operator manually pulls out the rotor assembly 202, thereby achieving the separation of the handlebar bracket 200 and the rotor assembly 202.

[0039] Example 2

[0040] Combined with attachment Figure 1-7This embodiment provides a throttle bracket disassembly machine. Based on the above embodiment, the following improvements can be made: the chuck 120 includes a plurality of clips 124 arranged in a surrounding array, with gaps between the clips 124. A guide block 125 is provided at the end of the clip 124. The tightening slope 123 is located on the side of the guide block 125 facing the clip 124, the gathering slope 122 is located on the side of the guide block 125 away from the clip 124, and the reducing adapter slope 121 is located on the side of the clip 124 facing the clamping shaft 110. In this embodiment, the chuck 120 is composed of a plurality of clips 124 arranged in a surrounding array, and the gaps between the clips 124 ensure that the chuck 120 has good elastic deformation ability, thereby ensuring the effectiveness of the throttle bracket disassembly machine.

[0041] Example 3

[0042] Combined with attachment Figure 1-7 This embodiment provides a throttle bracket disassembly machine. Based on the above embodiment, the following improvements are made: a positioning piece 126 is disposed between the clamping pieces 124. The end of the positioning piece 126 is located on the side of the variable diameter adapting surface close to the fixed plate 103. A limit block 127 is provided on the positioning piece 126. The limit block 127 is configured to abut against the inner wall of the throttle bracket 200. In this embodiment, a positioning piece 126 is further provided to support the limit block 127. Because the end of the positioning piece 126 is located on the side of the variable diameter adapting surface close to the fixed plate 103, the limit block 127 is located on the side of the variable diameter adapting surface and does not affect the tension of the chuck 120. The limit block 127 abuts against the inner wall of the throttle bracket 200, effectively providing a positioning and support function for the throttle bracket 200, thereby maintaining a fixed position relative to the structure formed by the chuck 120, the clamping shaft 110, and the clamping nozzle 130.

[0045] Example 5

[0046] Combined with attachment Figure 1-7This embodiment provides a throttle bracket disassembly machine. Based on the above embodiment, the following improvements can be made: the first drive member 101 and the second drive member 102 are arranged in opposite directions, the output end of the first drive member 101 is fixedly connected to the frame structure, and the push plate 104 is fixedly connected to the frame structure. This embodiment is a configuration of the first and second drive members 101, 102. In this embodiment, the output ends of the first and second drive members 101, 102 face opposite directions, and the first drive member 101 is connected to the push plate 104 via the frame structure. This configuration allows the first and second drive members 101, 102 to be placed at the same level, saving space.

[0047] Example 6

[0048] Combined with attachment Figure 1-7 This embodiment proposes a throttle bracket disassembly machine, which can be improved on the basis of the above embodiment as follows: the frame structure includes a frame plate 105, and at least one threaded rod 106 is provided on the frame plate 105. Through holes are provided on the frame plate 105 and the push plate 104, and the threaded rod 106 passes through the through holes. The threaded rod 106 is fixedly connected to the frame plate 105 and the push plate 104 through nuts. This embodiment is a setting method of the frame structure. In this embodiment, the frame structure includes at least one threaded rod 106. Since the screw rod passes through the through hole, the threaded rod 106 is fixedly connected to the frame plate 105 and the push plate 104 through a nut. Therefore, the relative position between the push plate 104 and the fixed plate 103 can be adjusted, thereby ensuring that the tightening part formed by the variable diameter adaptation bevel 121 on the chuck 120, and the part formed by the retracting bevel 122 and the tightening bevel 123 to give the bevel tightening force to the claw 201 can be adjusted to a suitable relative position with the claw 201 inside the handle bracket 200.

In this embodiment, the positioning block 107 is provided to adjust the relative position between the throttle and the push plate 104, thereby ensuring that the tensioning portion formed by the variable diameter adaptation inclined surface 121 on the chuck 120, as well as the portion formed by the retraction inclined surface 122 and the tightening inclined surface 123 that applies the inclined tightening force to the clamping claw 201, can be adjusted to a suitable relative position with the clamping claw 201 inside the throttle bracket 200.
