Description

Technical Field

[0001] The present application relates to the field of mechanical engineering technology, and in particular to a ring-shaped arm side plate fixing tool. Background Art

[0002] As an indispensable component of the automobile structure, the ring arm bears the important responsibility of supporting, connecting and protecting the key parts of the automobile. Therefore, its manufacturing precision and quality requirements are extremely high.

[0003] The production of this precision part requires a series of rigorous and meticulous processing steps. First, the raw material of the ring arm undergoes preliminary cutting and forming to complete the rough processing stage. The main purpose of this stage is to remove excess material and roughly form the basic outline of the ring arm. Subsequently, in order to further improve the dimensional accuracy and surface finish of the part and meet specific mechanical performance requirements, the ring arm will be sent to a high-precision machine tool for finishing.

[0004] In order to effectively improve processing efficiency and ensure stability and safety during the processing, workers need to fix the ring arm on a special fixing frame, and then install the fixing frame on the machine tool for subsequent processing.

[0005] The existing fixing frame system used for the ring arm consists of a main frame and multiple rotatable positioning frames installed on its side walls. The rotation of these positioning frames is achieved by hydraulic cylinders. When in use, the staff will first place the ring arm on the main frame, and then drive the positioning frames to rotate so as to firmly fix the ring arm. This design enables the machine tool to maintain higher stability when processing the ring arm.

[0006] However, each fixed frame is equipped with multiple positioning frames, so multiple hydraulic cylinders are needed to drive them to rotate, which requires a large number of pipes to connect these hydraulic cylinders. These pipes are prone to leakage during use, greatly increasing the difficulty of subsequent maintenance. Utility Model Content

[0007] In order to solve the above problems, the present application provides a ring-shaped arm side panel fixing tool, which is intended to

[0008] By optimizing the structural design, simplifying the drive mechanism, and enhancing the reliability and maintainability of the system, the processing efficiency of the ring arm is effectively improved.

[0009] The present application provides a ring-shaped arm side panel fixing tool, which adopts the following technical solution:

[0010] A ring-shaped arm side plate fixing tool comprises a main frame, a hydraulic cylinder arranged on the main frame, a pressing frame is provided at the driving end of the hydraulic cylinder, and the pressing frame can rotate with the driving end of the hydraulic cylinder as a rotation axis;

[0011] The compression frame includes a main crossbar and a plurality of brackets arranged on the main crossbar, wherein the brackets are provided with a plurality of compression blocks for fixing the side plates of the ring-shaped arms;

[0012] The outer side wall of the hydraulic cylinder is provided with a guide plate, a guide groove is opened on the guide plate, and a sliding rod is provided on the main cross bar. The end of the sliding rod close to the guide groove is slidably connected to the inner wall of the guide groove.

[0013] By adopting the above technical solution: using a single hydraulic cylinder to drive the pressing frame to rotate, compared with the traditional method of multiple hydraulic cylinders driving multiple positioning frames, the driving mechanism is greatly simplified. This not only reduces the number of hydraulic cylinders and corresponding pipelines, reducing the complexity of the system, but also helps to reduce the occurrence of potential problems such as leakage, thereby improving the reliability and maintainability of the system;

[0014] In addition, a guide plate is provided on the outer wall of the hydraulic cylinder, and a guide groove is opened on the guide plate. At the same time, a sliding rod is provided on the main cross bar and is slidingly connected to the guide groove. This not only provides guidance and limiting functions for the rotation of the pressing frame, but also enhances the stability of the pressing frame during the rotation process, and reduces the possibility of damage to the hydraulic cylinder body during rotation.

[0015] Preferably, the main crossbar is provided with a cavity for mounting the bracket, a first through hole, and a second through hole. The cavity passes through the upper and lower surfaces of the main crossbar, and the first through hole and the second through hole are connected to the cavity.

[0016] The bracket is provided with a mounting block adapted to be mounted in the cavity, the mounting block is provided with a third through hole, the aperture of the third through hole is the same as the aperture of the first through hole and the second through hole, the first through hole, the second through hole and the third through hole are provided with studs, and nuts are provided at both ends of the studs;

[0017] The lower end of the side arm of the bracket is provided with an installation groove for installing the pressure block, a fourth through hole and a fifth through hole, the installation groove passes through the front and back surfaces of the lower end of the side arm of the bracket, and the fourth through hole and the fifth through hole are connected to the installation groove;

[0018] A sixth through hole is provided on the pressing block, and the aperture of the sixth through hole is the same as that of the fourth through hole and the fifth through hole. Studs are provided in the fourth through hole, the fifth through hole and the sixth through hole, and nuts are provided at both ends of the studs.

[0019] By adopting the above technical solution: opening multiple through holes on the main cross bar and the bracket, and fixing them with double-headed studs and nuts, the installation process is simplified, while the overall structural strength of the tooling is enhanced, and the stability, flexibility and maintainability of the tooling are improved.

[0020] Preferably, the main crossbar is composed of a main section and sections rotatably arranged at both ends of the main section, and the main section is provided with a lifting mechanism for controlling the lifting of the bracket.

[0021] By adopting the above technical solution: during the processing, the height of the bracket is adjusted using the lifting mechanism, and then the annular arm side plate is placed in the appropriate position, and then the height of the bracket is lowered, and the hydraulic cylinder drives the pressing block to be pressed against the annular arm side plate to achieve fixation.

[0022] Preferably, the lifting mechanism includes a supporting frame, a movable arm, a single-headed bolt vertically penetrating the supporting frame, and a ring threadedly connected to the single-headed bolt; through grooves are provided on both sides of the supporting frame, and the movable arm passes through the through grooves, and its two ends are respectively hinged to the ring and the segment.

[0023] By adopting the above technical solution, the position of the collar on the bolt can be precisely adjusted by rotating the single-head bolt, thereby driving the movable arm to move up and down. This design not only achieves precise control of the lifting action, but also ensures stability and reliability during the lifting process.

[0024] Preferably, a pressure relief assembly is provided between the bracket and the pressing block.

[0025] By adopting the above technical solution: the service life of the bracket and the pressing block can be extended. During the long-term processing process, the bracket and the pressing block will be subjected to continuous wear and impact. The addition of the pressure-reducing component can reduce such wear and impact, thereby extending the service life of the bracket and the pressing block and reducing production costs;

[0028] By adopting the above technical solution: the combination of the stud, spring and nut constitutes a simple and effective pressure regulation and buffering system. When the pressure block applies pressure to the stud, the spring will be compressed, thereby absorbing and dissipating part of the pressure. This design can effectively reduce the direct impact of the pressure block on the bracket, protecting the bracket from damage. At the same time, by adjusting the position of the nut, the preload force of the spring can be easily adjusted, thereby achieving precise control of the pressure.

[0029] This allows the tooling to be fine-tuned according to different processing requirements and the material properties of the ring arm side panels, ensuring stability and precision during the processing.

[0030] Preferably, a flexible gasket is provided at the point where the stud abuts against the pressing block.

[0031] By adopting the above technical solution: the flexible gasket has a certain elasticity and deformation ability.

This design makes the pressure distribution more uniform, reducing the risk of processing errors and workpiece damage caused by excessive local pressure.

[0032] Preferably, the hydraulic cylinder and the guide plate are both detachably arranged on the main frame.

[0033] By adopting the above technical solution: During the processing, the tooling may accumulate some debris, oil stains and other impurities.

The hydraulic cylinder and guide plate are set to be detachable, which can facilitate the cleaning and maintenance of these components to ensure that they are always in good working condition.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. This application uses a single hydraulic cylinder to drive the compression frame to rotate, greatly simplifying the use of multiple hydraulic cylinders and corresponding pipes in traditional fixed frame systems, reducing system complexity.

[0045] The following is combined with Figure 1-6 This application is described in further detail.

[0046] Example 1

[0047] Example 1 of the present application discloses a ring-shaped arm side plate fixing tool, referring to Figure 1 , including a main frame 1, on which two hydraulic cylinders 2 are symmetrically installed, and the driving output ends of the hydraulic cylinders 2 are each equipped with a pressing frame 3, which can rotate with the driving end of the hydraulic cylinder 2 as the rotation axis, and at the same time, the driving end of the hydraulic cylinder 2 can drive the pressing frame 3 to perform linear motion along the movement direction of the piston rod;

[0048] The compression frame 3 consists of a main crossbar 31 and two brackets 32 symmetrically mounted at both ends of the main crossbar 31. Two pressure blocks 33 are symmetrically mounted on each bracket 32 ​​to compress and fix the annular arm side plates. The center of the main crossbar 31 is connected to the driving end of the hydraulic cylinder 2.

[0049] A guide plate 4 is mounted on the outer periphery of the hydraulic cylinder 2. The guide plate 4 is annular in structure. The hydraulic cylinder 2 is mounted inside the guide plate 4. Two arc-shaped guide grooves 41 are symmetrically formed on the guide plate 4. The angle of the arc corresponding to the center of the circle is 90 degrees. Two sliding rods 35 are vertically mounted on the main crossbar 31. The end of the sliding rod 35 away from the main crossbar 31 is slidably connected to the inner wall of the guide groove 41.

[0050] The hydraulic cylinder 2 and the guide plate 4 are both detachably mounted on the main frame 1 .

[0051] A single hydraulic cylinder 2 can drive the clamping frame 3 to fix the eight annular arm side plates, reducing the number of hydraulic cylinders 2 and pipelines, thereby reducing maintenance costs; at the same time, the guide groove 41 opened on the guide plate 4 is slidably adapted to be connected with the sliding rod 35 installed on the clamping frame 3, thereby providing guidance and limiting effects for the rotation of the clamping frame 3, enhancing the stability of the clamping frame 3 during the rotation process, and reducing the possibility of damage to the hydraulic cylinder 2 body during rotation, thereby ensuring safety and stability during the processing process.

[0052] Reference Figure 2 and Figure 3 A cavity 311 is vertically formed at both ends of the main crossbar 31, and a first through hole 312 and a second through hole 313 are formed. The opening direction of the first through hole 312 and the second through hole 313 is perpendicular to the opening direction of the cavity 311, and the first through hole 312 and the second through hole 313 are connected to the cavity 311;

[0053] The bracket 32 ​​connected to both ends of the main crossbar 31 has a mounting block 321 at its upper end, which can be inserted into the cavity 311 and adapted to the cavity 311. A third through hole 322 is formed through the mounting block 321. The aperture of the third through hole 322 is the same as the aperture of the first through hole 312 and the second through hole 313. The first through hole 312, the second through hole 313 and the third through hole 322 are aligned, and the stud 323 is inserted at the same time. The two ends of the stud 323 are tightened with the nut 113 to install the bracket 32 ​​on the main crossbar 31.

[0054] A mounting groove 324 is formed at the connection between the lower end of the side arm of the bracket 32 ​​and the pressure block 33. A fourth through hole 325 and a fifth through hole 326 are also formed. The mounting groove 324 passes through the front and back surfaces of the lower end of the side arm of the bracket 32, and the fourth through hole 325 and the fifth through hole 326 are connected to the mounting groove 324.

[0055] A sixth through hole 327 is formed through the pressing block 33 connected to the lower end of the bracket 32. The diameter of the sixth through hole 327 is the same as the diameter of the fourth through hole 325 and the fifth through hole 326. The fourth through hole 325, the fifth through hole 326 and the sixth through hole 327 are aligned, and the stud 323 is inserted at the same time. The two ends of the stud 323 are tightened with the nut 113 to install the pressing block 33 on the upper bracket 32.

[0056] A plurality of through holes are provided on the main cross bar 31 and the bracket 32 ​​and fixed with studs 323 and nuts 113, which can simplify the installation process, enhance the overall structural strength of the tooling, and improve the stability, flexibility and maintainability of the tooling.

[0057] The working process and implementation principle of Example 1 are as follows:

[0058] First, the operator manually adjusts the position of the main crossbar 31 by slightly rotating it approximately 90 degrees to the preset working state. This rotation process is due to the precise guide groove 41 design on the guide plate 4 and the sliding rod 35 cleverly installed on the main crossbar 31. The tight sliding fit between the sliding rod 35 and the guide groove 41 not only ensures the accuracy of the rotation direction of the main crossbar 31, but also significantly improves the stability of the pressing frame 3 during the rotation process, effectively avoiding potential damage to the hydraulic cylinder 2 due to improper operation.

[0059] Next, the annular arm side panels to be processed are properly placed on the main frame 1, specifically on both sides of the guide plate 4. Subsequently, the main crossbar 31 is rotated in the opposite direction to restore it to its initial state, in preparation for the subsequent pressing operation.

[0060] Subsequently, the hydraulic cylinder 2 is started, and its powerful driving force is used to push the clamping frame 3 to move linearly along the direction of the piston rod. During this process, the clamping block 33 on the clamping frame 3 gradually approaches and fits tightly against the annular arm side plate, thereby achieving effective compression and fixation of the annular arm side plate.

[0061] Example 2

[0062] Example 2 of the present application discloses a ring-shaped arm side plate fixing tool, referring to Figure 4 and Figure 5 , which is different from Example 1 in that the main crossbar 31 is no longer an integral structure, but is composed of a main section 5 and two subsections 6 rotatably arranged at both ends of the main section 5, and a lifting mechanism is installed on the main section 5 to control the rotation of the subsections 6 to achieve the lifting of the bracket 32;

[0063] The lifting mechanism consists of a carrier frame 7 installed above the center of the main section 5, a single-headed bolt 9 vertically penetrating the carrier frame 7, a collar 10 threadedly connected to the single-headed bolt 9, and a movable arm 8. Through slots 71 are provided on both sides of the carrier frame 7, and the movable arm 8 passes through the through slots 71, so that the collars 10 and the segment 6 at both ends are hingedly connected. When it is necessary to lift the bracket 32, it is only necessary to simply rotate the single-headed bolt 9 to drive the collar 10 to move up and down on the bolt. The movement of the collar 10 will further drive the movable arm 8 to rotate, thereby realizing the lifting operation of the segment 6. During this process, the segment 6 will rotate around its rotation connection point with the main section 5, thereby driving the entire bracket 32 ​​to be lifted.

[0064] In order to extend the service life of the bracket 32 ​​and the pressing block 33 and enable the tooling to be fine-tuned according to different processing requirements and the thickness characteristics of the ring arm side plate, refer to Figure 6 A pressure-reducing assembly 11 is installed between the bracket 32 ​​and the pressure block 33, which consists of a stud 111 abutting the pressure block 33, a spring 112 sleeved on the stud 111, and a nut 113. A vertical hole 12 is opened above the support arm for the stud 111 to pass through, and the nut 113 is installed above the spring 112 to adjust the compression amount of the spring 112. At the same time, a flexible gasket 13 is also installed at the point where the stud 111 abuts the pressure block 33, so that the pressure distribution is more uniform, reducing the risk of processing errors and workpiece damage caused by excessive local pressure.

[0065] The working process and implementation principle of Example 2 are as follows:

[0066] Manually adjust the position of the main crossbar 31 by slightly rotating it about 90 degrees to position it in the preset working state. At this time, the segment 6 of the main crossbar 31 is in the initial state, that is, it is parallel or nearly parallel to the main segment 5;

[0067] Rotate the single-head bolt 9. The rotation of the single-head bolt 9 drives the collar 10 to move on the bolt. The movement of the collar 10 further drives the movable arm 8 to rotate. The rotation of the movable arm 8 drives the segment 6 to rotate around its rotation connection point with the main segment 5, thereby achieving the lifting operation of the bracket 32. During the lifting process, the segment 6 will rise smoothly, driving the entire bracket 32 ​​to lift until it reaches the preset height.

[0068] Place the annular arm side panels to be processed properly on the main frame 1, on both sides of the guide plate 4.

[0069] Subsequently, the main cross bar 31 is rotated in the opposite direction to restore it to its initial state, and the single-head bolt 9 is rotated at the same time to lower the bracket 32. Finally, the hydraulic cylinder 2 is started to push the clamping frame 3 to move linearly along the direction of the piston rod, so that the clamping block 33 on the clamping frame 3 gradually approaches and fits tightly against the side plate of the annular arm, thereby realizing the clamping and fixing operation.

[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
