Description

Technical Field

[0001] This utility model relates to the field of electric bicycle parts processing and manufacturing, specifically to a rear pedal clamp. Background Technology

[0002] The rear pedal of an electric bicycle is a key component that bears the load of the rider's feet. Its structure is usually made of metal, such as aluminum alloy, steel, or high-strength composite materials, and it needs to have characteristics such as lightweight, high rigidity, and fatigue resistance. In the mass production process, the processing of the rear pedal involves multiple processes such as drilling, milling, and tapping. Its precision and consistency directly affect the overall assembly quality of the vehicle and riding safety.

[0003] However, traditional processing methods face the problem of low assembly efficiency. Specifically, the rear pedals are mostly irregular curved surfaces or structures with complex contours. General-purpose fixtures need to be repeatedly adjusted to adjust the positioning reference, resulting in excessively long clamping time for a single piece, which makes it difficult to meet the needs of large-scale production. Utility Model Content

[0004] The purpose of this invention is to provide a rear pedal to solve one of the problems raised in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A rear pedal clamp includes a base with a sloping groove and a recessed groove. The bottom surface of the sloping groove extends from its base to the surface of the base. A first inclined surface is provided on the base and connects to the sloping groove. Two defects are formed downward on the first inclined surface. Two arcuate grooves are provided on the bottom surface of the sloping groove, and rib grooves are respectively connected between the two arcuate grooves and the two defects. A first locking block is provided in the sloping groove, and a second locking block is provided in the recessed groove. The first locking block and the second locking block are detachably connected to the base.

[0007] Preferably, there are two first locking blocks, which are respectively located on both sides above the inclined groove.

[0008] Preferably, the bottom of the first locking block is provided with a clearance groove.

[0009] Preferably, the first locking block and the second locking block are respectively provided with threaded holes, and the base is provided with corresponding threaded holes, and the first locking block and the second locking block are respectively bolted to the base.

[0010] The rear pedal clamp of this utility model has the following advantages compared with the prior art:

[0011] This invention, by setting inclined grooves and countersunk grooves, and cooperating with a first locking block and a second locking block, can stably clamp the rear pedal in different states, preventing displacement during processing or assembly. Furthermore, the fixture of this invention only requires placing the rear pedal into the inclined groove or countersunk groove, and then connecting the locking block to the base to complete the clamping. This solves the problem in existing technologies where general-purpose fixtures require repeated adjustments to the positioning reference, resulting in excessively long clamping times for single parts.

[0012] The design of the first inclined surface, the defect, the arc groove, and the rib groove enhances the fit between the shape of the clamp and the shape of the rear pedal, thereby improving the clamping accuracy.

[0013] The first and second locking blocks are detachably connected, which facilitates replacement or adjustment and reduces maintenance costs.

[0014] The clearance groove at the bottom of the first locking block can reduce interference with the workpiece and improve clamping efficiency.

[0015] The rib groove between the arc groove and the defect can enhance the structural strength, while ensuring accurate workpiece positioning and reducing machining errors. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: base 1, inclined groove 2, countersunk groove 3, first inclined surface 4, defect 5, arc groove 6, rib groove 7, first locking block 8, second locking block 9, clearance groove 10, and threaded hole 11.

[0022] As attached Figure 1-4 As shown in the figure, this embodiment illustrates a rear pedal clamp, mainly used for stable clamping of the rear pedal during mechanical assembly or processing. The clamp adopts a modular design, achieving efficient clamping of the rear pedal through the combination of a base 1, a slanted groove 2, a countersunk groove 3, and a detachable locking block, exhibiting high stability and flexibility.

[0023] Specifically, the rear pedal clamp includes a base 1, which serves as the core support component of the clamp and is made of high-strength metal materials, such as cast iron or aluminum alloy, to ensure structural rigidity and durability.

[0024] Furthermore, the base 1 is provided with a sloping groove 2 and a countersunk groove 3. The bottom surface of the sloping groove 2 extends from the bottom of the sloping groove 2 to the surface of the base 1, forming a smooth transition, which facilitates the installation and positioning of the workpiece. The base 1 is provided with a first inclined surface 4, which is connected to the sloping groove 2. Two defective parts 5 are formed downward on the first inclined surface 4. The function of the defective parts 5 is to adapt and match the shape of the rear pedal.

[0025] The inclined groove 2 has two arc-shaped grooves 6 on its bottom surface, and each of these grooves 6 connects to a rib groove 7 at one of the two defect sections 5. The rib groove 7 is designed to fit the shape of the rear pedal. The inclined groove 2 is equipped with a first locking block 8, and the recessed groove 3 is equipped with a second locking block 9. Both the first locking block 8 and the second locking block 9 are detachably connected to the base 1. Both are detachably connected for easy adjustment and maintenance.

[0026] Two first locking blocks 8 are provided, one on each side above the inclined groove 2, forming a symmetrical clamping structure to improve clamping stability. The bottom of the first locking block 8 is provided with an avoidance groove 10 to prevent interference with the workpiece during the locking process and ensure that the clamping surfaces fit tightly.

[0027] The first locking block 8 and the second locking block 9 are respectively provided with threaded holes 11, and the base 1 is provided with corresponding threaded holes 11. The first locking block 8 and the second locking block 9 are respectively bolted to the base 1 to ensure reliable connection and easy disassembly and adjustment.

[0028] Work process:

[0029] Place the rear pedal in the inclined groove 2 and recess 3 of the base 1, ensuring it aligns with the bottom surfaces of both grooves. Adjust the position of the rear pedal to match the corresponding structures of the arc groove 6 and rib groove 7, ensuring accurate positioning. Then, install the first locking block 8 and the second locking block 9 onto the inclined groove 2 and recess 3 respectively, and tighten them with bolts to press the locking blocks firmly against the workpiece, preventing loosening. After fixing, subsequent processing, welding, or assembly operations can be performed.

[0030] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
