Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting cleaning, and more specifically, to a multi-functional hanging shot blasting tooling. Background Art

[0002] In industrial production, in order to improve the surface quality of metal products, remove oxide scales, rust and other impurities on the surface, the shot blasting treatment process has been widely used. In order to ensure that the surface of the workpiece can be fully treated, the workpiece is usually hung on a rack and then put into a shot blasting machine for shot blasting treatment. However, the number of workpieces that can be placed by the hanging tooling in the prior art is fixed, and the number of workpieces placed each time cannot be increased. When dealing with a large number of workpieces, the efficiency is low.

[0003] Regarding the above problems, for the technical problem that the existing multi-functional hanging shot blasting tooling cannot increase the number of workpieces placed each time and has low efficiency when dealing with a large number of workpieces, after a large number of searches, a multi-functional hanging shot blasting tooling with the patent publication number CN218613527U was found, which includes a hanging ring and a connecting frame. A plurality of connecting frames are arranged in sequence from top to bottom. The connecting frame includes a connecting ring in a circular ring shape. A plurality of connecting rods are vertically arranged on the connecting ring. The middle parts of the connecting ring and the connecting rods are connected. A connecting cavity is opened at the bottom of the connecting rod, and the opening of the connecting cavity faces downward. A connecting block matching with the connecting cavity is arranged at the top of the connecting rod. A plurality of force dividing rods are radially arranged on the inner wall of the connecting ring. A lifting rod is vertically arranged at the center of the connecting ring. A plurality of force dividing rods are connected to the same lifting rod. The top of the lifting rod is detachably connected to the hanging ring. A plurality of hooks are arranged on both the connecting ring and the force dividing rods. A fixing device for fixing the connecting block and the connecting cavity is also arranged on the connecting rod. The utility model can adjust the number of connecting frames according to different numbers of workpieces, has a simple structure, is convenient for connection and disassembly operations, and can process a large number of workpieces at one time. However, the technical solution provided by this patent has the following problems:

[0004] (1) According to the disclosed patent CN218613527U, the connecting rod has a fixed length. This design of the connecting rod with a fixed length has obvious limitations in actual production. For relatively tall workpieces, due to the too small distance between the hanging rods, the workpiece may not be fully suspended, and some areas may contact or collide with other components, affecting the shot blasting treatment effect and even damaging the workpiece. For relatively short workpieces, the too large distance between the hanging rods will cause waste of space and reduce production efficiency.

[0005] (2) The hanging rods on the hanging shot blasting tooling are generally fixed to the device by welding. This welding fixation method makes it inconvenient to disassemble the hanging rods. However, in actual production, when shot blasting workpieces of different specifications are required and thus different specifications of hanging rods need to be replaced, due to the difficulty of disassembling the existing hanging rods, the flexible change requirements cannot be met, which greatly limits the scope of use of the tooling.

[0006] The utility model facilitates the processing of workpieces at different heights, meets the production requirements, and improves work efficiency; moreover, it can quickly disassemble and assemble the hanging rods, flexibly meet the change requirements of workpieces of different specifications, and thus greatly expands the scope of use of the tooling. Summary of the Utility Model

By means of the adjustment component, it facilitates the processing of workpieces at different heights, meets the production requirements, and improves work efficiency; by means of the disassembly and assembly component, the hanging rods can be quickly disassembled and assembled, flexibly meet the change requirements of workpieces of different specifications, and thus greatly expands the scope of use of the tooling.

[0008] To achieve the above object, the utility model provides the following technical solution: a multifunctional hanging shot blasting tooling, comprising: a mounting ring, an outer ring of the mounting ring is provided with a plurality of hanging rods, a disassembly and assembly component is arranged between the hanging rods and the mounting ring, a connecting rod is arranged inside the mounting ring, there are three connecting rods, and adjustment components are respectively arranged between the connecting rods and the mounting ring; the disassembly and assembly component includes a limiting ring, an internal thread ring arranged on the outer side of the limiting ring, an external thread ring arranged on the outer surface of the internal thread ring, a thread piece fixed on the outer side of the external thread ring, and a tightening ring tightened on the outer ring of the thread piece; the adjustment component includes a connecting block, an internal groove opened inside the connecting block, a spring arranged inside the internal groove, a limiting block slidably connected inside the internal groove, a pin fixed to the limiting block, a pull rod connected to the outside of the pin, a slider arranged inside the mounting ring, a card slot opened at both ends of the slider, and a sliding groove opened on the surface of the connecting rod.

[0009] Further preferred scheme: The limiting ring is fixedly connected to the outer surface of the mounting ring respectively. An internal thread ring is fixedly connected to the outer side of the limiting ring. Threads are arranged on the outer surface of the internal thread ring. The outer surface of the internal thread ring is threadedly connected with an external thread ring, and threads matching the internal thread ring are arranged inside the external thread ring.

[0010] Further preferred scheme: The external thread ring is fixedly connected to the thread piece. The thread piece is conical. The outer surface of the thread piece is threadedly connected with a tightening ring. Matching threads are arranged on the inner surface of the tightening ring and the outer surface of the thread piece. A rubber pad is fixedly connected inside the tightening ring.

[0011] Further preferred solution: A chute is provided on the surface of the connecting rod that contacts the mounting ring. A slider is slidably connected inside the chute. The slider is fixedly connected to the mounting ring. Card slots are respectively provided at both ends of the slider, and a retaining pin is snap-fitted inside the card slots.

[0012] Further preferred solution: Connecting blocks are respectively fixedly connected to both ends of the connecting rod. An inner groove is provided inside the connecting block. A spring is telescopically arranged inside the inner groove, and the spring is wound around the outer surface of the retaining pin.

[0013] Further preferred solution: The retaining pin penetrates through the outside of the inner groove and is fixedly connected to a pull rod.

[0015] Beneficial effects:

[0016] 1. By configuring the adjustment component, for workpieces of different heights, pull the pull rod outwards, so that the retaining pin is separated from the card slot. At this time, the spring is in a compressed state. Then, pull the mounting ring up and down to make the slider slide up and down inside the chute, thereby driving the hanging rod to move up and down. When the hanging rod is adjusted to the appropriate position, release the pull rod. With the resilience of the spring, the retaining pin can be inserted into the card slot again. When the retaining pin is inserted into the card slot, a firm connection can be provided to fix the mounting ring, thereby achieving the adjustment of the height of the hanging rod.

[0017] 2. By setting the disassembly and assembly component, when it is necessary to replace the hanging rod of different specifications, rotate the tightening ring so that it no longer squeezes the threaded piece. Then the threaded piece releases the squeezing and fixing of the hanging rod, and thus the hanging rod can be removed. When it is necessary to install the hanging rod, pass one end of the hanging rod through the threaded piece, the external thread ring, the tightening ring, the internal thread ring and the limiting ring in sequence. Then rotate the tightening ring in the reverse direction to make the threaded piece gradually parallel to the limiting ring. At this time, the inside of the threaded piece will be in close contact with the outer surface of the hanging rod, thereby achieving the squeezing and fixing of the hanging rod. The rubber pad inside the threaded piece has a large friction force, which can enhance the friction force between the threaded piece and the outer surface of the hanging rod, making the fixing of the hanging rod more stable and reducing the possibility of the hanging rod loosening or displacing during the work process. Through this rapid disassembly and assembly method of the hanging rod, the changing requirements of workpieces of different specifications are flexibly met, and thus the use range of the tooling is greatly expanded.

[0018] 3.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Figures 1-6 Please refer to

[0027] Please refer to Figure 1-6, in the embodiment of the present utility model, a multi-functional hanging shot blasting tooling includes: an installation ring 3, which serves as the core connecting component, provides an installation basis for the hanging rod 4 and the connecting rod 5, integrates and supports the entire tooling structure. The hanging rod 4 is arranged on the outer ring of the installation ring 3, and several hanging rods 4 are provided, which are used to mount workpieces. The setting of multiple hanging rods 4 can process multiple workpieces simultaneously, improving production efficiency. A disassembly and assembly component is arranged between the hanging rod 4 and the installation ring 3. The connecting rod 5 is arranged inside the installation ring 3, and three connecting rods 5 are provided. The connecting rod 5 is located inside the installation ring 3 to enhance the structural stability, and the height adjustment of the installation ring 3 is realized through an adjustment component. Adjustment components are respectively arranged between the connecting rod 5 and the installation ring 3; The disassembly and assembly component includes a limit ring 17, which limits the insertion depth of the hanging rod 4 to ensure accurate installation position. An internal thread ring 19 arranged on the outer side of the limit ring 17 is matched with an external thread ring 20 to achieve threaded connection, providing a basis for fixation and adjustment. An external thread ring 20 arranged on the outer surface of the internal thread ring 19 is matched with the internal thread ring 19 to realize the relative position fixation and adjustment between components. A thread piece 16 fixed on the outer side of the external thread ring 20 realizes the extrusion fixation or release of the hanging rod 4 by tightening or loosening the tightening ring 15, facilitating the disassembly, replacement of the hanging rod 4. The tightening ring 15 tightened around the outer ring of the thread piece 16 controls the tightening degree of the thread piece 16, thereby fixing or loosening the hanging rod 4; The adjustment component includes a connection block 8, which provides a basis for installing and connecting other components. An internal groove 11 opened inside the connection block 8 provides an installation space for components such as a spring 12 and a limit block 14. A spring 12 arranged inside the internal groove 11 provides a resilience force, enabling the pin 13 to automatically reset and insert into the card slot 7 after the pull rod 9 is released. A limit block 14 slidably connected inside the internal groove 11 limits the movement range of the pin 13 to prevent its excessive movement. The pin 13 fixedly connected to the limit block 14 is matched with the card slot 7 to realize the fixation and height adjustment of the installation ring 3. The pull rod 9 connected to the outside of the pin 13 is used to pull the pin 13 to realize the separation of the pin 13 from the card slot 7. A slider 6 arranged inside the installation ring 3 slides in the chute 10 to realize the up and down movement of the installation ring 3. Card slots 7 opened at both ends of the slider 6 are matched with the pin 13 to fix the position of the installation ring 3. A chute 10 opened on the surface of the connecting rod 5 provides a track for the sliding of the slider 6.

[0028] In the embodiment of the present utility model, the limiting ring 17 is fixedly connected to the outer surface of the mounting ring 3 respectively, providing a stable mounting foundation for the internal thread ring 19, ensuring that the position of the internal thread ring 19 is fixed during operation without deviation or shaking. The internal thread ring 19 is fixedly connected to the outside of the limiting ring 17, providing an internal thread structure to cooperate with the external thread ring 20 to achieve threaded connection and adjustment and fixation of the relative position. Threads are provided on the outer surface of the internal thread ring 19. The external thread ring 20 is threadedly connected to the outer surface of the internal thread ring 19. Through the threaded connection, the external thread ring 20 can rotate and move along the internal thread ring 19, thereby adjusting the position of the external thread ring 20 relative to the internal thread ring 19. Threads matching those of the internal thread ring 19 are provided inside the external thread ring 20 to ensure that the external thread ring 20 can closely cooperate with the internal thread ring 19 to achieve precise threaded connection, thus realizing stable connection and position adjustment functions.

[0029] In the embodiment of the present utility model, the external thread ring 20 is fixedly connected to the threaded piece 16, enabling the threaded piece 16 to move and rotate together with the external thread ring 20, ensuring consistent movement during adjustment. The threaded piece 16 is conical in shape. When the tightening ring 15 moves along the threaded piece 16, due to the conical structure of the threaded piece 16, its diameter changes, thereby realizing the extrusion fixation or relaxation of the hanging rod. The tightening ring 15 is threadedly connected to the outer surface of the threaded piece 16. By rotating the tightening ring 15, it moves on the threaded piece 16, changing the opening degree of the threaded piece 16 to achieve the purpose of fixing or loosening the hanging rod. Threads matching each other are provided on the inner surface of the tightening ring 15 and the outer surface of the threaded piece 16 to ensure that the tightening ring 15 can move smoothly and precisely along the threaded piece 16 to achieve effective adjustment functions. The rubber pad 18 is fixedly connected inside the tightening ring 15, increasing the friction when contacting the hanging rod 4, improving the stability of fixation, and at the same time playing a certain protective role for the hanging rod 4, reducing wear and extrusion damage.

[0030] In the embodiment of the present utility model, the sliding groove 10 is opened on the surface where the connecting rod 5 contacts the mounting ring 3, providing a track and space for the sliding of the slider 6, restricting its sliding direction and range. The slider 6 is slidably connected inside the sliding groove 10, and the slider 6 can smoothly move up and down inside the sliding groove 10, thereby driving the mounting ring 3 fixedly connected thereto to achieve height adjustment. The slider 6 is fixedly connected to the mounting ring 3, transmitting the movement of the mounting ring 3 to the slider 6 to ensure that the movement of the mounting ring 3 can be realized through the sliding of the slider 6 inside the sliding groove 10. Card slots 7 are respectively opened at both ends of the slider 6, providing a position for the snap pin 13 to be snapped, realizing the fixation of the position of the slider 6, and further fixing the height of the mounting ring 3. The snap pin 13 is snap-connected inside the card slot 7. When the snap pin 13 is snapped into the card slot 7, it can prevent the movement of the slider 6, thereby fixing the mounting ring 3 at a specific height position.

[0031] In the embodiment of the present utility model, the connecting blocks 8 are respectively fixedly connected to both ends of the connecting rod 5, providing an installation position for internal structures such as the inner groove 11, and at the same time enhancing the stability and integrity of the connection between the connecting rod 5 and other components. An inner groove 11 is provided inside the connecting block 8, providing a receiving space for components such as the spring 12 and the pin 13, ensuring a suitable environment for the installation and operation of these components. A spring 12 is telescopically arranged inside the inner groove 11, and the spring 12 can provide an elastic restoring force. When the pin 13 is pulled outwards to separate it from the card slot 7, the spring 12 is compressed. After releasing the pin 13, the elastic force of the spring 12 can prompt the pin 13 to reset and re-engage with the card slot 7 to achieve the fixing function. The spring 12 is coiled around the outer surface of the pin 13. On the one hand, it provides a certain limitation and guidance for the position of the spring 12, making its telescopic movement more stable; on the other hand, it enables the elastic force of the spring 12 to effectively act on the pin 13, ensuring the coordinated cooperation between the movement of the pin 13 and the telescopic movement of the spring 12.

[0032] In the embodiment of the present utility model, a pull rod 9 is fixedly connected to the outside of the inner groove 11 through the pin 13. The pull rod 9 provides a force application point for manual operation. By pulling the pull rod 9, the pin 13 can be driven to move, realizing the separation of the pin 13 from the card slot 7, and thus performing the height adjustment operation of the mounting ring 3. A limiting block 14 is fixedly connected to the outer surface of the pin 13, restricting the moving range of the pin 13 during the telescopic process of the spring 12, preventing the pin 13 from moving excessively and detaching from the inner groove 11 or the spring 12, and ensuring the stability and reliability of the movement of the pin 13. The limiting block 14 is fixedly connected to the inner side of the spring 12, and the limiting block 14 is slidably connected to the inner wall of the inner groove 11, providing guidance and support for the movement of the limiting block 14, enabling the limiting block 14 and the pin 13 connected thereto to move smoothly along a predetermined direction, and at the same time ensuring the accuracy and stability of the telescopic movement of the pin 13.

[0033] In the embodiment of the present utility model, the support rods 2 are respectively fixedly connected to the inside of the connecting rod 5, enhancing the connection stability between the connecting rods 5 and improving the strength and rigidity of the overall structure. The support rods 2 are evenly distributed in a triangular shape at the upper end inside the mounting ring 3. The triangular distribution has good stability and can evenly bear the tensile and compressive forces from above, making the entire structure more stable when bearing the weight of the mounted workpiece. A hook 1 is fixedly connected to the upper end of the intersection of the support rods 2, providing a mounting point for connecting with external equipment and facilitating the suspension of the entire tooling inside the shot blasting equipment. The hook 1 is perpendicular to the support rod 2, ensuring that the tensile force borne by the hook 1 can be directly transmitted to the support rod 2, reducing the dispersion and loss of force, and enabling the tensile force to be more effectively borne by the support rod 2 and the entire structure, thereby ensuring the stability and reliability of the tooling during suspension.

[0034] Working principle: First, according to workpieces of different heights, pull the pull rod 9 outwards, so that the pin 13 is separated from the card slot 7. At this time, the spring 12 is in a compressed state. Then, pull the mounting ring 3 up and down, causing the slider 6 to slide up and down inside the chute 10, thereby driving the hanging rod 4 to move up and down. When the hanging rod 4 is adjusted to the appropriate position, release the pull rod 9. With the resilience of the spring 12, the pin 13 can be inserted into the card slot 7 again. When the pin 13 is inserted into the card slot 7, it can provide a firm connection to fix the mounting ring 3, thus achieving the adjustment of the height of the hanging rod 4. This adjustment method facilitates the processing of workpieces of different heights, meets the production requirements, improves work efficiency. After adjusting the height distance between the hanging rods 4, hang the workpiece on the hanging rod 4. Finally, hang the entire tooling at a specific position inside the shot blasting equipment through the hook 1 to ensure the stability of the tooling during the shot blasting process. When it is necessary to replace the hanging rod 4 of different specifications, rotate the tightening ring 15 so that it no longer squeezes the threaded piece 16. Then the threaded piece 16 releases the squeezing and fixing of the hanging rod 4, and thus the hanging rod 4 can be removed. When it is necessary to install the hanging rod 4, pass one end of the hanging rod through the threaded piece 16, the external thread ring 20, the tightening ring 15, the internal thread ring 19 and the limit ring 17 in sequence. Then rotate the tightening ring 15 in the reverse direction to make the threaded piece 16 gradually parallel to the limit ring 17. At this time, the inside of the threaded piece 16 will be in close contact with the outer surface of the hanging rod 4, thereby realizing the squeezing and fixing of the hanging rod 4. The rubber pad 18 inside the threaded piece 16 has a large friction force, which can enhance the friction force between the threaded piece 16 and the outer surface of the hanging rod 4, making the fixing of the hanging rod 4 more stable and reducing the possibility of loosening or displacement of the hanging rod 4 during the working process. Through this quick disassembly and assembly method of the hanging rod 4, it flexibly meets the changing requirements of workpieces of different specifications, and thus greatly expands the use range of the tooling.
