Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts processing equipment, and particularly relates to a clamp device for automobile calipers. BACKGROUND

[0002] With the rapid development of intelligentization and electrification of the automobile industry, the design iteration cycle of automobile calipers is greatly shortened, and higher requirements for the flexibility and efficiency of production and manufacturing are put forward. Automobile calipers are of various types and specifications, and in the process of production and detection, corresponding clamps need to be used for clamping and fixing them, and the clamps need to be inevitably disassembled and replaced.

[0003] A clamp for machining automobile brake caliper blanks is provided in Chinese Patent No. CN217668054U. Through the combined design of the base plate, the clamping assembly and the connecting plate, the functions of multi-workpiece clamping and overturning are realized. However, the following shortcomings exist in the actual application of this scheme:

[0004] 1. Insufficient safety and stability: The pressure arms driven by the air cylinders may fail when the air pressure fluctuates or the air cylinders malfunction, resulting in the risk of workpiece falling off. During the overturning process, the symmetry of the clamping assemblies on both sides of the base plate may be destroyed due to installation errors or wear, which may cause the center of gravity to deviate and affect the stability of the machining.

[0005] 2. Precision limitation: The positioning of the workpiece relies on three-point support and the bifurcated pressure of the pressure arms, but the uneven surface of the blank may easily lead to a decrease in positioning repeatability. Although the cooperation of the positioning key block and the pressure block can improve the positioning accuracy of the seat plate, the wear of the keyway after long-term use may introduce micron-level errors, affecting the high-precision machining requirements.

[0006] 3. Incomplete efficiency optimization: The four clamping assemblies need to be clamped twice (first on the top surface and then on the bottom surface after overturning), and the overturning and secondary clamping still occupy additional time, which does not realize the true meaning of "synchronous" clamping. The response speed of the air cylinder drive is affected by the air source pressure, which may become a bottleneck in the efficiency in continuous high-speed machining scenarios.

[0007] 4. Limited universality: The clamp is designed specifically for brake caliper blanks, and the structure of the support seat and the pressure arm is suitable for specific workpiece shapes, making it difficult to adapt to other irregular or significantly different size parts. The thickness of the base plate and the air cylinder embedding method limit the adjustment of the spacing of the clamping assemblies, and cannot flexibly adapt to different specifications of workpieces.

[0008] Therefore, how to provide a quick replacement device for an automobile caliper clamp system, which integrates a precise positioning and locking mechanism and a high-efficiency clamping and self-locking structure, realizes the quick replacement of caliper tooling of different models and types, and improves the clamping replacement efficiency, ensures the positioning accuracy and universal adaptability, has become a problem to be solved in the current automobile parts processing field.

[0047] Figure 6 FIG. 2 is a partial structure example diagram of a clamp device for a vehicle caliper according to an embodiment of the present application, Figure 7 FIG. 3 is another partial structure example diagram of a clamp device for a vehicle caliper according to an embodiment of the present application, as Figures 1 to 7 As shown, in this embodiment, the horizontal locking assembly E includes a plug-in mechanism E1 and a one-way stop mechanism E2 arranged on one side of the plug-in mechanism E1. The end of the plug-in mechanism E1 can be inserted into or pulled out of the locking groove C11 on the side of the clamp platform C1, and the one-way stop mechanism E2 can one-way lock and stop the end of the plug-in mechanism E1.

[0048] As an optional example, in this embodiment, the plug-in mechanism E1 includes a second hydraulic part E11 and a plug-in part E12 connected with the output part of the second hydraulic part E11. The plug-in part E12 includes an integral connected ratchet strip part E121 and a wedge block part E122. Under the action of the second hydraulic part E11, the plug-in part E12 can perform extension and retraction movement, so that the wedge block part E122 can be inserted into or pulled out of the locking groove C11 on the side of the clamp platform C1.

[0049] As an optional example, in this embodiment, the one-way stop mechanism E2 includes a stop bracket E21, a rotary motor E22 arranged on the upper part of the stop bracket E21, and a stop yoke E23 connected with the output end of the rotary motor E22. The yoke claw tip E231 at the bottom end of the stop yoke E23 is sawtooth-shaped and matches the tooth groove of the ratchet strip part E121. When the rotary motor E22 is powered on or powered off, the stop yoke E23 is driven to rotate, so that the yoke claw tip E231 at the bottom end of the stop yoke E23 engages or separates from the tooth groove of the ratchet strip part E121.

[0050] When the prong claw tip E231 at the bottom end of the stop prong E23 engages with the tooth groove of the ratchet bar portion E121, if the insertion and extraction portion E12 moves toward the direction of the clamp assembly C, the prong claw tip E231 slides along the tooth surface of the ratchet bar portion E121, and if the insertion and extraction portion E12 moves away from the direction of the clamp assembly C, the prong claw tip E231 is clamped into the tooth groove of the ratchet bar portion E121 to limit and lock the ratchet bar portion E121 and the wedge block portion E122. That is, after the prong claw tip E231 engages with the tooth groove of the ratchet bar portion E121, the one-way movement of the wedge block portion E122 is realized, and only the movement of the wedge block portion E122 in the locking direction is allowed, and the mechanical self-locking is formed when moving in the opposite direction, so that the stable locking of the clamp assembly C is realized.

[0051] In the one-way stop mechanism E2 of the embodiment, the prong claw tip E231 of the stop prong E23 and the ratchet bar portion E121 of the insertion and extraction portion E12 are mechanically engaged by the tooth shape to realize one-way constraint. When the insertion and extraction portion E12 completes the locking action, the prong claw tip E231 is clamped into the tooth groove of the ratchet bar portion E121. Even if the motor is stopped due to power failure, the physical structure of the mechanical tooth engagement can still maintain the self-locking state, realizing “power failure without losing lock”.

[0052] The application principle of the automobile caliper clamp device of the embodiment is as follows:

[0053] In actual application, different clamp assemblies C are selected according to different types and categories of automobile caliper clamps.

[0054] When it is necessary to disassemble and replace the clamp assembly C, the rotary motor E22 of the horizontal locking assembly E is powered on, the stop prong E23 is rotated by the output end of the rotary motor E22, the prong claw tip E231 is separated from the tooth groove of the ratchet bar portion E121, and the mechanical self-locking is released; then, the second hydraulic portion E11 drives the insertion and extraction portion E12 to retract, the wedge block portion E122 is driven to exit the locking slot C11 of the clamp platform C1, and the horizontal locking force is released. At the same time, the locker body D1 of the longitudinal locking assembly D receives the air release signal through the gas interface D2, the locking hole D4 is retracted in the radial direction, and the locking protrusion C21 of the positioning boss C2 is separated, and the longitudinal locking state is released.

[0055] Then, the clamp assembly C is lifted upward, the positioning boss C2 at the bottom thereof is separated from the positioning slot B1 of the positioning seat B, the locking protrusion C21 completely exits the locking hole D4, and the clamp assembly C to be disassembled is removed from the positioning seat B.

[0056] In the installation of the replaced clamp assembly C, the clamp assembly C is aligned with the positioning seat B, the bottom positioning boss C2 is embedded in the positioning groove B1 of the positioning seat B, and the locking protrusion C21 is inserted into the assembly hole B3, so that the preliminary positioning is completed. The locker body D1 of the longitudinal locking assembly D receives the inflation signal through the gas interface D2, the locking hole D4 extends radially and tightly fits the outer wall of the locking protrusion C21, so that the central position of the clamp assembly C is locked and the radial displacement is limited. The second hydraulic part E11 of the horizontal locking assembly E drives the plug-in part E12 to extend and push the wedge-shaped block part E122 to move horizontally along the positioning seat B and make it inserted into the locking groove C11 of the clamp platform C1. By using the slope effect of the wedge surface of the wedge-shaped block part E122, the horizontal thrust is converted into the vertical downward clamping force, so that the clamp assembly C is pressed tightly on the top surface of the positioning seat B. At the same time, the rotary motor E22 is electrified, the stopper pull fork E23 is rotated through the output end of the rotary motor E22, the pull fork jaw tip E231 is embedded in the tooth groove of the ratchet bar part E121, the one-way tooth shape of the ratchet bar part E121 cooperates with the sawtooth-shaped profile of the pull fork jaw tip E231, and only the wedge-shaped block part E122 is allowed to move in the clamping direction, and is automatically locked when moving in the reverse direction, so that the mechanical self-locking is formed, and the stable clamping state is ensured. After the clamp assembly C is clamped, the hydraulic clamping assembly C3 on the clamp platform C1 is started, and the positioning block C4 is matched to realize accurate positioning and clamping of the automobile caliper workpiece placed thereon, and the device enters the working state.

[0057] In practical application, the automobile caliper clamp device of the embodiment of the present application has the following beneficial technical effects through comprehensive structural design:

[0058] 1. Safe and reliable locking mechanism

[0059] The longitudinal pneumatic locking and horizontal hydraulic-mechanical self-locking double-restraint structure is constructed by the longitudinal locking assembly D and the horizontal locking assembly E, and the three-dimensional restraint of "longitudinal anti-movement + horizontal anti-deviation" is formed. Even if a single locking mechanism fails, the other mechanism can still maintain the locking state, avoiding the risk of workpiece falling off.

[0063] In the disassembly process, the longitudinal locking assembly D and the horizontal locking assembly E can quickly switch from the locked state to the disengaged state, realizing tool-free quick unlocking and significantly improving the disassembly efficiency.

[0064] 4. Enhance universal adaptability

[0065] Through the modular design of the "universal base part + replaceable tool plate", only the hydraulic clamping assembly C3 and the positioning block C4 of the clamp assembly C are adjusted according to the specific specifications and types of the automobile caliper, and the remaining parts do not need to be replaced, so that different types of workpieces such as new energy automobile calipers and traditional fuel automobile calipers can be adapted, the repeated design and manufacturing links of special fixtures are saved, and the universal adaptability of the device is significantly improved.
