Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology, specifically to an automatic installation device for brake chamber clamps. Background Technology

[0002] The spring brake chamber is a crucial component of the air pressure braking system in commercial vehicles, typically comprising a front body, a middle body, and a rear body connected as a single unit. For example, a disc spring brake chamber disclosed in Chinese invention patent CN105485218A has its front body and middle body tightly connected by an external clamp, which is equipped with locking bolts and locking nuts. In existing assembly processes, the installation of the clamp largely relies on manual operation. Specifically, operators must manually fit the clamp onto the rolled edges of the front and middle bodies and pre-tighten the locking bolts. This process is not only inefficient and labor-intensive, but also makes it difficult to ensure uniform force on the clamp, posing a risk of inconsistent tightening torque. This could lead to the chamber loosening due to vibration during long-term use, affecting sealing performance and driving safety.

[0003] Currently, although some automated assembly equipment exists on the market, it generally has limited adaptability and is difficult to adapt to air chamber products with different models and different mounting bolt phase angles. For the specific process of clamp installation, there is a lack of dedicated automated equipment that can integrate positioning, clamping, and bolt tightening. Utility Model Content

[0004] In order to enable automatic, accurate and reliable installation of brake clamps, this utility model provides an automatic installation device for brake clamps in brake chambers.

[0005] The technical solution adopted by this utility model is as follows: An automatic installation device for brake chamber clamps, comprising: a workbench; an annular fixed base, fixedly installed on the workbench, with a movable base detachably embedded inside, the internal shape of which is adapted to the rear body shape of the brake chamber, and a coaxial through hole provided at the center of the fixed base and the movable base for the release bolt and release nut of the brake chamber to pass through; three clamp clamping mechanisms, distributed circumferentially on the left, right and rear sides of the fixed base, each clamp clamping mechanism including a horizontally arranged clamping block, a horizontal cylinder for driving the clamping block to move horizontally, and a guide rod-guide sleeve mechanism for guiding the clamping block; a top clamping mechanism, disposed above the workbench, including a clamping assembly, a clamping cylinder for driving the clamping assembly to move vertically, and a slider-guide rail structure for guiding the clamping assembly; and a wrench for tightening the clamp locking bolt.

[0006] Preferably, the movable base is a replaceable part, and the rear body of the brake chamber of different specifications and sizes can be adapted by replacing the movable base with different internal contours.

[0007] Preferably, the clamping assembly includes: a cylindrical body with a flange at its upper end; a fixed end cap, which is fixed to the lower side of the slider of the slider-guide rail structure by fasteners, the fixed end cap having a central hole, the upper end of the cylindrical body passing through the central hole and forming a rotatable connection structure with the fixed end cap through the flange; an upper clamping block, which is integrally formed with the lower end of the cylindrical body; and a lower clamping block, which is detachably connected to the upper clamping block, and its lower surface is used to clamp the front of the brake chamber.

[0008] Preferably, the lower clamping block is made of engineering plastic.

[0009] Preferably, the upper clamping block and the lower clamping block are respectively provided with a central clearance hole and multiple edge clearance holes. The central clearance hole is used to avoid the top rod of the brake chamber, and the edge clearance holes are used to avoid the mounting bolts of the brake chamber.

[0010] Preferably, the guide rod-guide sleeve mechanism includes a guide rod fixedly connected to the pressure block and a guide sleeve fixed to the bracket of the horizontal cylinder.

[0011] Preferably, the piston rod end of the clamping cylinder is connected to the upper side of the slider of the slider-guide rail structure.

[0012] Preferably, the wrench is an electric torque wrench.

[0013] This utility model has the following beneficial effects: 1. Automation and consistency of clamp installation: The equipment integrates multiple clamp clamping mechanisms distributed circumferentially and an overall clamping mechanism at the top. Through pneumatic drive and precision guidance, it replaces the traditional manual fitting and pre-tightening operation that relies on manual labor, improves assembly efficiency, reduces labor intensity, ensures uniform force on the clamp in the circumferential direction, avoids the problem of inconsistent locking force caused by manual operation, and ensures the reliability of product sealing performance and driving safety. 2. Versatility and adaptability: The replaceable movable base can be quickly adapted to brake chamber rear bodies of different specifications and sizes, improving the equipment's adaptability to different models of products and reducing the investment and management costs of special tooling. 3. Adaptive installation phase angle: The top clamping assembly adopts a rotatable connection structure, which allows the clamping block to rotate and adjust according to the actual angle of the mounting bolt after contacting the front body of the air chamber. This solves the problem of changes in the phase angle of the mounting bolt caused by differences in air chamber model or placement angle, and achieves precise coordination of clamping and avoidance, thereby improving the success rate and reliability of automated assembly. 4. Protective function: The clamping block adopts a split design, with the lower clamping block made of engineering plastic, which not only ensures sufficient clamping force, but also effectively prevents scratches or bumps on the surface of the air chamber parts during the clamping process, thus ensuring the appearance quality of the product.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0020] In the embodiments, such as Figures 1-4The diagram shows an automatic installation device for brake chamber clamps, comprising: a workbench 1; an annular fixed base 2, fixedly installed on the workbench 1, with a detachable movable base 3 embedded inside, the internal shape of which is adapted to the external shape of the rear body 3a of the brake chamber, and a coaxial through hole 4 at the center of the fixed base 2 and the movable base 3 for the release bolt 5a and release nut 6a of the brake chamber to pass through; three clamping mechanisms, distributed circumferentially on the left, right and rear sides of the fixed base 2, each clamping mechanism including a horizontally arranged pressure block 5, a horizontal cylinder 6 for driving the pressure block 5 to move horizontally, and a guide rod-guide sleeve mechanism 7 for guiding the pressure block 5; a top clamping mechanism, located above the workbench 1, including a clamping assembly 8, a clamping cylinder 9 for driving the clamping assembly 8 to move vertically, and a slider-guide rail structure 10 for guiding the clamping assembly 8; and a wrench 11 for tightening the locking bolts of the clamp 4a. The workbench 1 provides a stable foundation for the equipment. The annular fixed base 2 and the replaceable movable base 3 together form a modular positioning unit. By replacing the movable base 3, different specifications of the rear body 3a can be quickly adapted, greatly improving the versatility of the equipment. The central through hole 4 ensures compatibility with the protruding parts at the rear end of the brake chamber, achieving unobstructed positioning. The clamping mechanisms in three directions can move simultaneously from the circumference to the center. The clamping block 5 ensures that the clamping block 4a is evenly pressed into the rolled edge grooves of the front body 1a and the middle body 2a, avoiding deformation or jamming of the clamping block 4a due to unilateral force. The guide rod-guide sleeve mechanism 7 ensures the accuracy and smoothness of the movement trajectory of the clamping block 5, improving the reliability of the operation. The top clamping mechanism applies a stable downward pressure to the front body 1a of the brake chamber from above. In cooperation with the positioning base below, it firmly presses the entire chamber into the working position, preventing the chamber from moving or tilting during clamping and bolt tightening, ensuring the stability and accuracy of the assembly process.

[0021] In the embodiments, such as Figure 2 As shown, the movable base 3 is a replaceable part. By replacing the movable base 3 with different internal contours, it can be adapted to the rear body 3a of the brake chamber of different specifications and sizes. The movable base 3 improves the flexibility and versatility of the equipment, enabling a production line to cope with the production of multiple product models by quickly replacing the low-cost movable base 3, significantly reducing equipment investment and tooling management costs.

[0022] In the embodiments, such as Figure 2 , Figure 4As shown, the clamping assembly 8 includes: a cylindrical body 8.1 with a flange 8.2 at its upper end; a fixed end cap 8.3, which is fixed to the lower side of the slider of the slider-guide structure 10 by fasteners, and the fixed end cap 8.3 has a central hole 8.4. The upper end of the cylindrical body 8.1 passes through the central hole 8.4 and forms a rotatable connection structure with the fixed end cap 8.3 through the flange 8.2; an upper clamping block 8.5, which is an integral structure with the lower end of the cylindrical body 8.1; and a lower clamping block 8.6, which is detachably connected to the upper clamping block 8.5, and its lower surface is used to clamp the front body 1a of the brake chamber. The unique design of the clamping assembly 8, especially the rotatable connection structure formed by the flange 8.2 and the fixed end cap 8.3, allows the entire clamping assembly 8 to have freedom of movement around its axis while clamping vertically. This allows the clamping assembly 8 to be rotated and adjusted when there is a slight angular deviation between the clearance hole on the clamping block and the position of the air chamber mounting bolt 8a, thereby ensuring that the clearance hole can be accurately fitted into the bolt. This achieves perfect coordination between the "clamping" and "clearance" functions and solves the automation problem caused by product phase angle differences.

[0023] In this embodiment, the lower clamping block 8.6 is made of engineering plastic. The lower clamping block 8.6, which is in direct contact with the product surface, is made of engineering plastic, which not only ensures the required strength and clamping force, but also effectively prevents scratches or bumps on the machined surface of the brake chamber front body 1a during the clamping process due to its softer material, thus providing good protection for the product and ensuring the appearance quality of the finished product.

[0024] In the embodiments, such as Figure 4 As shown, the upper clamping block 8.5 and the lower clamping block 8.6 are respectively provided with a central clearance hole 8.7 and multiple edge clearance holes 8.8. The central clearance hole 8.7 is used to avoid the push rod 7a of the brake chamber, and the edge clearance holes 8.8 are used to avoid the mounting bolt 8a of the brake chamber. The design of the central clearance hole 8.7 and the edge clearance holes 8.8 avoids all protruding parts (push rod 7a and mounting bolt 8a) on the front body 1a of the brake chamber, so that the clamping assembly 8 can be smoothly pressed down to the end face of the front body 1a without interfering with any parts, ensuring the smooth execution of the clamping action and the safety of the equipment. The edge clearance holes 8.8 here are elongated holes to improve their adaptability.

[0025] In the embodiments, such as Figure 3 As shown, the guide rod-guide sleeve mechanism 7 includes a guide rod 7.1 fixedly connected to the pressure block 5 and a guide sleeve 7.2 fixed to the bracket of the horizontal cylinder 6. The guide rod-guide sleeve mechanism 7 provides high-precision linear guidance for the horizontal movement of the pressure block 5, effectively resists the lateral force generated when clamping the clamp, prevents the cylinder piston rod from bearing radial load, thereby extending the service life of the cylinder and ensuring the repeatability and positioning accuracy of the pressure block 5.

[0026] In the embodiments, such as Figure 2 As shown, the piston rod end of the clamping cylinder 9 is connected to the upper side of the slider of the slider-guide structure 10. This direct connection efficiently transmits the output force of the clamping cylinder 9 to the slider-guide structure 10, driving the entire clamping assembly 8 to perform stable vertical movement. The slider-guide structure 10 has strong load-bearing capacity and high guiding accuracy, ensuring that the clamping assembly 8 will not wobble under heavy loads, thus ensuring the verticality and uniformity of the clamping force.

[0027] In this embodiment, an electric torque wrench is used, which can automatically complete the final tightening of the locking bolt and ensure that its tightening torque reaches the preset value. This realizes the automation and standardization of the tightening process, eliminates the problem of inconsistent torque caused by human factors, and ensures the uniformity and reliability of product quality.

[0028] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
