Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a bushing processing device. Background Technology

[0002] In modern industrial production, bushings, as a key mechanical component, are widely used in various types of machinery and equipment, playing an important role in reducing friction, buffering vibration, and positioning. With the continuous development of industrial manufacturing technology, higher requirements are being placed on the machining accuracy and production efficiency of bushings.

[0003] In bushing machining, the bushing machining device is one of the core pieces of equipment ensuring machining quality and efficiency. The tooling used to clamp the bushing is a crucial component of this device. Currently, in practical applications, this tooling typically needs to work in conjunction with other equipment, such as lathes and grinding machines, to complete the bushing machining process. However, the connection method between the tooling and other equipment is mostly bolted. While bolted connections are a common and traditional method with a certain degree of versatility, they have revealed several problems in the actual use of bushing machining devices. On the one hand, when connecting the tooling to other equipment via bolts, slight differences in bolt tightening and installation position can easily lead to positional deviations between the tooling and the equipment. These positional deviations directly affect the machining accuracy of the bushing, increasing the dimensional error of the machined bushing and failing to meet the demands of high-precision industrial production. On the other hand, the bolted connection process is relatively cumbersome, requiring each bolt to be tightened or loosened individually. When the tooling needs frequent changes or adjustments, this significantly increases operating time and labor intensity, reduces production efficiency, and is detrimental to large-scale industrial production.

[0004] In summary, existing bushing machining equipment and tooling using bolt connections have significant shortcomings in terms of positional accuracy and ease of connection. Therefore, a bushing machining device is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by fitting a sleeve frame over the connector, ensuring precise alignment of the positioning hole and locking groove with a limiting plate, and then using an adjusting component to control the insertion of the locking rod to complete the connection. This avoids the positional deviation problems of traditional bolt connections and improves the bushing machining accuracy. For disassembly, the adjusting component is reversed to pull out the locking rod, and the second bolt is unscrewed to remove the sleeve frame. This eliminates the need to tighten each bolt individually, simplifying operation, saving time and manpower, and improving production efficiency.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problem that the existing bushing processing device tooling with bolt connection has obvious deficiencies in terms of positional accuracy and connection convenience through the following technical solution.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A bushing processing apparatus, comprising:

[0009] A bushing fixture, wherein a fixture support is provided on the bushing fixture;

[0010] Mounting base, located below tooling support;

[0011] Connectors are mounted on the tooling support;

[0012] A frame is installed on the mounting base;

[0013] Two sets of locking rods are provided. The connector has symmetrical positioning holes on both sides. The inner wall of the sleeve has locking grooves at both ends. The locking rod passes through the positioning hole and is inserted into the locking groove through the adjusting component.

[0014] The connector is connected to the tooling support via an adjustment and fixing assembly, and the sleeve frame is connected to the mounting base via a disassembly assembly.

[0015] Preferably, the adjusting and fixing components are symmetrically connected to the mounting columns on both sides of the tooling support, the connecting parts are provided with adjustment slots on both sides, and the threaded ends of the mounting columns extending to the outside of the adjustment slots are threadedly connected with fastening sleeves for fixing the connecting parts.

[0016] Preferably, a stabilizing protrusion is glued to one end of the fastening sleeve contacting the outer wall of the connector to enhance the fixing stability.

[0017] Preferably, a plurality of preset holes are evenly provided on both sides of the outer wall of the connector, and the preset holes are threadedly connected to the outer wall of the tooling support by the first bolt.

[0018] Preferably, the disassembly assembly includes a bottom frame connected to the bottom of the sleeve frame, and each of the four corners of the bottom frame is connected with a second bolt by a thread to fix the sleeve frame to the mounting base.

[0019] Preferably, the upper surface of the mounting base has an inner groove, and the bottom frame is inserted into the inner groove.

[0020] Preferably, the adjusting assembly includes a rotating rod movably mounted inside the rear end of the connector via a bearing. A first bevel gear is connected to the front end of the rotating rod. A reverse screw is horizontally mounted in the cavity at the bottom of the connector via a bearing. A second bevel gear is connected to the reverse screw and meshes with the first bevel gear. Both ends of the reverse screw are threadedly connected to a kit. The kit is connected to the locking rod via a movable plate. A stabilizing rod is provided at the front end of the cavity of the connector. The other end of the kit is slidably connected to the stabilizing rod.

[0021] Preferably, both ends of the outer wall of the connector are connected to limit plates to restrict the sleeve frame.

[0022] Preferably, the end of the movable plate that is in close contact with the inner wall of the connector is provided with a convex pad, and the convex pad is made of rubber.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The bushing processing device provided in this application, by fitting a sleeve frame over the connector and using a limiting plate to precisely align the positioning hole and locking groove, and then using an adjusting component to control the insertion of the locking rod to complete the connection, avoids the positional deviation problem of traditional bolt connections and improves the bushing processing accuracy. During disassembly, the adjusting component is operated in reverse to pull out the locking rod, and the second bolt is unscrewed to remove the sleeve frame. This eliminates the need to tighten each bolt individually, simplifying operation, saving time and manpower, and improving production efficiency.

[0025] This application designs an adjustment and disassembly assembly, which significantly improves the convenience of connection operations. In the adjustment assembly, the mounting posts on both sides of the tooling support cooperate with the adjustment slots of the connector, allowing for flexible adjustment of the installation height, and the fastening sleeve can quickly lock the position. In the disassembly assembly, the four corners of the bottom frame of the sleeve frame are connected to the mounting base by second bolts, and the bottom frame cooperates with the inner groove on the mounting base to achieve pre-positioning, making installation and disassembly simple and time-saving.

[0026] The stabilizing ring at one end of the outer wall of the fastening sleeve contact connector is made of rubber, which increases the friction of the contact surface, effectively preventing the fastening sleeve from loosening and slipping, and ensuring a stable connection between the connector and the tooling support; the stabilizing rod in the adjustment assembly provides stable support for the movement of the kit, ensures the precise movement of the locking rod, avoids shaking or deviation during the adjustment process, maintains the stability of the device during operation, and thus ensures the stability and consistency of the bushing processing.

[0027] The frame and mounting base of this application are connected by a disassembly assembly. When the equipment is not in use, the second bolt can be easily unscrewed to remove the frame from the mounting base, which facilitates the disassembly and storage of the equipment and saves storage space.

[0040] Please see Figure 1-6 A bushing processing apparatus, comprising:

[0041] Bushing fixture 1, with fixture support 2 provided on bushing fixture 1;

[0042] Mounting base 3 is located below tooling support 2;

[0043] Connector 4 is mounted on tooling support 2;

[0044] The frame 5 is mounted on the mounting base 3;

[0045] Two sets of locking rods 7, with positioning holes 401 symmetrically opened on both sides of the connector 4, and locking grooves 701 opened at both ends of the inner wall of the sleeve 5.

[0046] The bushing processing device of this application is mainly composed of bushing tooling 1, tooling support 2, mounting base 3, connecting piece 4, sleeve frame 5, locking rod 7, positioning hole 401 and locking groove 701 and other components. The following is a detailed description of its structure and working principle.

[0047] I. Detailed Structure and Connection Methods of Each Component

[0048] Connection between bushing fixture 1 and fixture support 2

[0049] Bushing fixture 1 is used to fix the bushing to be processed, and its bottom is fixedly connected to fixture support 2. Fixture support 2 has symmetrical mounting posts 201 on both sides. The mounting posts 201 pass through the adjustment slots 403 on both sides of the connector 4 and are fixed by fastening sleeves 404. The fastening sleeves 404 are threaded to the threaded ends of the mounting posts 201, and their inner sides are glued with stabilizing rings 405 to increase friction and fixation stability.

[0050] Installation of mounting base 3 and sleeve 5

[0051] Mounting base 3 is located below tooling support 2, and its upper surface has an inner groove 301. A bottom frame 501 is welded to the bottom of the sleeve frame 5, and the bottom frame 501 is fixed to the inner groove 301 of the mounting base 3 by a second bolt 502, enabling quick assembly and disassembly. During disassembly, loosening the second bolt 502 allows the sleeve frame 5 to be separated from the mounting base 3.

[0052] Linkage between connector 4 and locking rod 7

[0053] The connector 4 has symmetrical positioning holes 401 on both sides, and the inner wall of the sleeve 5 has locking grooves 701 at both ends.

[0054] The locking rod 7 passes through the positioning hole 401 and is inserted into the locking groove 701 via the adjusting component 6, achieving precise positioning of the tooling support 2 and the mounting base 3. Limiting plate 402: Limiting plates 402 are provided at both ends of the connecting piece 4 to limit the movement range of the sleeve 5.

[0055] Adjustment component 6 transmission mechanism

[0056] The rotating rod 601 is mounted to the rear end of the connector 4 via a bearing, and its front end is connected to the first bevel gear 602. The reverse screw 603 is horizontally mounted in the cavity at the bottom of the connector 4, with threads in opposite directions at both ends, and is connected to the second bevel gear 604, meshing with the first bevel gear 602. The assembly 605 is connected to the locking rod 7 via a moving plate 606. When the rotating rod 601 is rotated, the reverse screw 603 drives the assembly 605 to move synchronously, thereby controlling the insertion or withdrawal of the locking rod 7. The other end of the assembly 605 is slidably connected to the stabilizing rod 608 to ensure stability during movement.

[0057] Working principle

[0058] When installing the bushing processing device, the first step is to connect the tooling support 2 to the connector 4. The mounting posts 201 on both sides of the tooling support 2 are inserted into the adjustment slots 403 on both sides of the connector 4. This design allows the tooling support 2 to move up and down within a certain range to accommodate the installation height requirements of different equipment. After adjusting the height, the tooling support 2 is fixed to the connector 4 by tightening the fastening sleeves 404 on the mounting posts 201. The stabilizing ring 405 glued to one end of the fastening sleeve 404 fits tightly against the outer wall of the connector 4. Utilizing the high friction properties of the rubber material, the fastening sleeve 404 effectively prevents loosening, ensuring a stable connection between the tooling support 2 and the connector 4. Furthermore, a first bolt 407 can be passed through the pre-drilled hole 406 on the connector 4 and tightened onto the outer wall of the tooling support 2 to further enhance the reliability of the connection and provide a stable foundation for subsequent processing.

[0059] When connecting the installed bushing fixture 1 to the main body mounting base 3, the sleeve frame 5 is placed over the connector 4. The limiting plate 402 on the outer wall of the connector 4 restricts the upward movement of the sleeve frame 5, ensuring that the positioning hole 401 on the connector 4 is precisely aligned with the locking groove 701 on the inner wall of the sleeve frame 5, achieving initial positioning. At this point, the adjustment assembly 6 is operated to complete the final connection. The rotating rod 601 of the adjustment assembly 6 is mounted on the rear end of the connector 4 via a bearing. Rotating the handle of the rotating rod 601 drives the first bevel gear 602 at the front end to rotate. The first bevel gear 602 meshes with the second bevel gear 604 on the horizontally mounted reverse screw 603 in the bottom cavity of the connector 4, thereby driving the reverse screw 603 to rotate. Since the threads at both ends of the reverse screw 603 are opposite in direction, its rotation will drive the fittings 605 at both ends to move along the screw axis. The fittings 605 are connected to the locking rod 7 via the moving plate 606, so the movement of the fittings 605 will drive the locking rod 7 to move synchronously. When the kit 605 moves away from each other, the locking rod 7 slides in the positioning hole 401 and inserts into the locking groove 701 on the inner wall of the sleeve frame 5, achieving a tight connection between the tooling and the main body of the equipment. The connection position is highly accurate, avoiding the position deviation problem that is prone to occur in traditional bolt connections.

[0060] During the operation of the adjustment component 6, the stabilizing rod 608 located at the front end of the cavity of the connector 4 plays a crucial role in ensuring the smooth movement of the kit 605. The other end of the kit 605 is slidably connected to the stabilizing rod 608, which provides stable support and guidance for the kit 605, preventing it from shifting or wobbling during movement. This ensures that the locking rod 7 can be accurately inserted into the locking groove 701, maintaining the stability of the entire connection structure. Consequently, it ensures the stability of the tooling during bushing processing, which is beneficial for improving the bushing processing accuracy.

[0061] The movable plate 606 has a rubber protruding pad 607 at one end that is in close contact with the inner wall of the connector 4. This design aims to reduce frictional wear between components. When the adjusting assembly 6 is working, the movable plate 606 moves inside the connector 4 along with the kit 605. The protruding pad 607 acts as a buffer layer, reducing the friction between the movable plate 606 and the inner wall of the connector 4, avoiding wear caused by direct friction between the two, extending the service life of the movable plate 606 and the connector 4, reducing equipment maintenance costs and downtime, and ensuring the continuous and stable operation of the equipment.

[0062] When it is necessary to disassemble bushing fixture 1 or replace sleeve frame 5, the disassembly assembly can be operated. The four corners of the bottom frame 501 of sleeve frame 5 are threaded to the mounting base 3 via second bolts 502. The inner groove 301 on the upper surface of the mounting base 3 engages with the bottom frame 501, serving as a pre-positioning mechanism during installation and facilitating the installation of the second bolts 502. For disassembly, simply unscrew the second bolts 502 to remove sleeve frame 5 from the mounting base 3; the operation is simple and quick. This design facilitates disassembly and storage of the equipment when not in use, saving space.

[0063] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
