Caliper casting slitting apparatus and method

Abstract

This invention discloses a caliper casting slitting device and method. The device includes a mounting bracket and an external cutting component. The mounting bracket has multiple clamping modules and a pull rod assembly on its top. Each clamping module includes a fixed clamping block and a movable clamping block, with a limit rod between the fixed and movable clamping blocks. Multiple clamping modules are used to clamp multiple calipers without obstructing the casting gate position. The pull rod assembly allows simultaneous operation and fixation of multiple clamping modules. When one or more calipers are slid, the remaining uncut calipers are still clamped and fixed, preventing them from falling and causing damage. Simultaneously, the movable assembly moves the clamping modules to ensure equal distances between them, enabling the clamping and fixing of multiple calipers with different casting gate lengths after molding, even with different caliper models. This makes the device more versatile and easier for operators to adjust.

Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, and particularly relates to a caliper casting and cutting device, and a cutting method for the caliper casting and cutting device. Background Technology

[0002] A car brake caliper is a component attached to the front and rear of the brake disc. The brake caliper contains one or more pistons. When the brake pedal is pressed, pressure is generated, which forces the brake fluid to push the pistons, which in turn pushes the brake pads inward to clamp the brake disc, thereby achieving the effect of braking and deceleration.

[0003] There are two methods for manufacturing automotive brake calipers: casting and forging. After the caliper is cast, the casting gate needs to be cut. In the existing technology, if a single tooling fixture clamps multiple connected calipers at the same time, it will block the casting gate. If each caliper is fixed individually, after the fixed caliper is cut, the other calipers will fall due to loss of fixation, making it inconvenient to clamp and fix multiple connected calipers. Summary of the Invention

[0004] This invention addresses the problem in existing technologies where it is inconvenient to clamp and secure multiple connected calipers, and proposes the following technical solution:

[0005] The mounting bracket and external cutting components are provided. One end of the mounting bracket is provided with a driving component. The top of the mounting bracket is provided with multiple clamping modules and a pull rod assembly. The clamping module includes a fixed clamping block and a movable clamping block. A limit rod is provided between the fixed clamping block and the movable clamping block. A spring is sleeved on the surface of the limit rod.

[0006] The drive unit drives the pull rod assembly to move back and forth, and multiple moving clamping blocks move in the opposite or opposite direction to the fixed clamping block. When the moving clamping blocks move relative to the fixed clamping block, multiple clamping modules simultaneously clamp and fix the caliper.

[0007] As a preferred embodiment of the above technical solution, the bottom of the mounting bracket is provided with a movable component, the movable component including a second driving component and a telescopic bracket, the top of multiple hinge centers of the telescopic bracket is fixedly connected to a fixed clamping block, and the hinge centers at both ends of the telescopic bracket are fixedly connected to a connecting block, one of the connecting blocks is fixedly connected to the mounting bracket, and a lead screw is rotatably inserted into the middle of the other connecting block, one end of the lead screw being fixedly connected to the output end of the second driving component.

[0008] As a preferred embodiment of the above technical solution, the pull rod assembly includes a moving rod and multiple different adjustment parts. Each adjustment part includes a rotating cylinder and a screw. One end of the screw is rotatably inserted into the interior of the rotating cylinder, and the other end of the screw is rotatably inserted into the end of the moving rod or the rotating cylinder. A steering bevel gear is provided on the surface of the rotating cylinder. A driven bevel gear is meshed with the bottom of the steering bevel gear. A spur gear is fixedly connected to the bottom of the driven bevel gear. A rack is meshed with one side of the spur gear, and the rack is fixedly connected to the mounting bracket.

[0009] As a preferred embodiment of the above technical solution, the adjustment part further includes a limiting block, which is fixedly connected to the surface of the screw, and one end of the limiting block is movably inserted into the inside of the fixing block.

[0010] As a preferred embodiment of the above technical solution, the middle part of the steering bevel gear is keyed, and the surface of the rotating cylinder at the keyway position is raised.

[0011] The cutting method of the caliper casting cutting device includes the following steps.

[0012] S1. Once the drive unit is activated, it moves the pull rod assembly, and multiple moving clamping blocks move in the opposite direction to the fixed clamping block to open the clamping module.

[0013] S2. The external feeding mechanism or the operator manually places the connected multiple calipers on the top of the mounting bracket. The drive unit drives the pull rod assembly to reset, so that the clamping module clamps and fixes the calipers at the corresponding positions.

[0014] S3. The external cutting component cuts off the casting port connecting the calipers one by one. Then the clamping module opens to remove the calipers after cutting, waiting for the next operation to begin.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. Multiple clamping modules are used to grip multiple calipers without obstructing the casting gate. The pull rod assembly allows simultaneous operation of multiple clamping modules for fixation. When one or more calipers are cut off, the remaining uncutable calipers are still clamped and fixed, preventing calipers from falling and injuring operators.

[0017] 2. By using the moving components to move the clamping modules simultaneously and make the distance between each clamping module the same, it can meet the clamping and fixing of multiple calipers with different caliper models and different casting gate lengths after molding, making the device more versatile and easier for operators to adjust.

[0018] 3. By utilizing the differences in each adjustment part, the pull rod assembly can automatically change its length, and the extension or retraction distance of each adjustment part is different. This allows the pull rod assembly to still operate multiple clamping modules for fixation even after each clamping module has moved a different distance. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] Figure 1 and Figure 3 In the middle, the mounting bracket 1 and the external cutting part are installed. One end of the mounting bracket 1 is provided with a driving component 2, which is a cylinder. The top of the mounting bracket 1 is provided with multiple clamping modules and a pull rod assembly. The clamping module includes a fixed clamping block 31 and a movable clamping block 32. A limit rod 33 is provided between the fixed clamping block 31 and the movable clamping block 32. A spring 34 is sleeved on the surface of the limit rod 33.

[0027] The drive component 2 drives the pull rod assembly to move back and forth, and the multiple moving clamping blocks 32 move toward the fixed clamping block 31 in the opposite or opposite direction. When the moving clamping blocks 32 move toward the fixed clamping block 31, the multiple clamping modules simultaneously clamp and fix the caliper.

[0028] When multiple calipers need to be clamped, the drive unit is activated to move the pull rod assembly. The pull rod assembly simultaneously moves multiple moving clamping blocks 32 toward the fixed clamping block 31. Under the restriction of the limit rod 33, the moving clamping blocks 32 move smoothly to clamp the calipers. Multiple calipers are clamped and fixed at the same time. Then, the external cutting component cuts off the casting port of the calipers, while the calipers that are not cut are still clamped and fixed to prevent the calipers from falling off and injuring the operator.

[0029] Multiple clamping modules are used to clamp multiple calipers without obstructing the casting gate position. The set pull rod assembly can operate multiple clamping modules simultaneously for fixation. When one or more calipers are cut off, the other uncutable calipers are still clamped and fixed to prevent the calipers from falling off and injuring the operator.

[0030] The cutting method of this caliper casting cutting device includes the following steps.

[0031] S1. The start of the drive unit 2 drives the pull rod assembly to move, and the multiple moving clamping blocks 32 move in the opposite direction to the fixed clamping block 31 to open the clamping module.

[0032] S2. The external feeding mechanism or the operator manually places the connected multiple calipers on the top of the mounting bracket 1. The drive component 2 drives the pull rod assembly to reset so that the clamping module clamps and fixes the calipers at the corresponding positions.

[0033] S3. The external cutting component cuts off the casting port connecting the calipers one by one. Then the clamping module opens to remove the calipers after cutting, waiting for the next operation to begin.

[0034] In the cutting method of this caliper casting cutting device, multiple clamping modules are used to clamp multiple calipers, while other uncut calipers are still clamped and fixed and will not fall off. In addition, the set pull rod assembly can operate multiple clamping modules at the same time for fixing, which makes it more convenient for operators to use.

[0035] Figure 2 In the mounting bracket 1, a movable component is provided at the bottom. The movable component includes a second driving component 51 and a telescopic bracket 52. The second driving component 51 is a motor. The top of multiple hinge centers of the telescopic bracket 52 is fixedly connected to a fixed clamping block 31. Connecting blocks 53 are fixedly connected to the hinge centers at both ends of the telescopic bracket 52. One of the connecting blocks 53 is fixedly connected to the mounting bracket 1, and a lead screw 54 is rotatably inserted into the middle of the other connecting block 53. One end of the lead screw 54 is fixedly connected to the output end of the second driving component 51.

[0036] Before cutting calipers with different spacing, start the second drive unit 51 to make it rotate the lead screw 54. The connecting block 53 that meshes with it will then move the telescopic bracket 52. During the telescopic bracket 52's extension or expansion, its multiple hinge centers will move, and the clamping module can move the corresponding distance to satisfy the clamping and fixing of calipers with different spacing.

[0037] By using a moving component to move the clamping modules simultaneously and ensuring that the distance between each clamping module is the same, it can meet the clamping and fixing of multiple calipers with different caliper models and different casting gate lengths after molding. This makes the device more versatile and easier for operators to adjust.

[0038] Figures 3-4 In this assembly, the pull rod includes a moving rod 41 and multiple different adjustment parts. Each adjustment part includes a rotating cylinder 42 and a screw 43. One end of the screw 43 is rotatably inserted into the rotating cylinder 42, and the other end of the screw 43 is rotatably inserted into the end of the moving rod 41 or the rotating cylinder 42. A steering bevel gear 44 is provided on the surface of the rotating cylinder 42. The steering bevel gear 44 has a keyway in the middle, and the surface of the rotating cylinder 42 is raised at the keyway position. A driven bevel gear 45 is meshed with the bottom of the steering bevel gear 44. A spur gear 46 is fixedly connected to the bottom of the driven bevel gear 45. A rack 47 is meshed with one side of the spur gear 46. The rack 47 is fixedly connected to the mounting bracket 1. The transmission ratio of the driven bevel gear 45 and the steering bevel gear 44 in each set of adjustment parts is different, and the lengths of the rotating cylinder 42 and the screw 43 in each set are different.

[0039] The adjustment part also includes a limiting block 48, which is fixedly connected to the surface of the screw 43, and one part of the limiting block 48 is movably inserted into the fixed clamping block 31.

[0040] Before adjusting the position of the clamping module using the moving component, obstructions are placed on the fixed clamping block 31 and the moving clamping block 32, so that the moving clamping block 32 is fixed relative to the fixed clamping block 31. Then, the moving component is used to drive the clamping module to move, and the driven bevel gear 45 drives the spur gear 46 to move. The spur gear 46 rotates along the surface of the rack 47, driving the driven bevel gear 45 to rotate. The steering bevel gear 44 then drives the rotating cylinder 42 to rotate. Since the limiting block 48 is fixedly connected to the surface of the screw 43, the limiting block 48 restricts the screw 43 to prevent it from rotating, so that the end of the screw 43 retracts into the rotating cylinder 42 or extends outward, so that the pull rod assembly automatically changes its length to meet the pushing work of multiple moving clamping blocks 32.

[0041] By utilizing the differences in each adjustment part, the pull rod assembly automatically changes its length, and each adjustment part extends or retracts by a different distance. This allows the pull rod assembly to still operate multiple clamping modules for fixation even after each clamping module has moved a different distance.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
