Description

Technical Field

[0001] This utility model relates to the field of fixed plate processing technology, specifically a truck axle fixed plate quick positioning device. Background Technology

[0002] The axle mounting plate is a key component of the vehicle chassis system. It is typically installed between the axle and the suspension or frame to fix and support the axle, transfer loads, and maintain wheel positioning. It generally adopts a ring-shaped or disc-shaped structure, featuring high strength and rigidity, capable of withstanding various forces and torques during vehicle operation, while also being easy to install and maintain, ensuring vehicle stability and safety.

[0003] The axle mounting plate needs to be connected to the axle, suspension, or frame via bolts. Therefore, precise bolt holes need to be machined on the mounting plate. However, the existing mounting plate fixing device is not convenient for quick positioning of the mounting plate during use, which requires additional time for position adjustment, thus affecting the processing efficiency of the mounting plate. Furthermore, the drilling process generates debris, which is troublesome for workers to clean up, further affecting the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick positioning device for truck axle mounting plates, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A truck axle mounting plate quick positioning device includes a housing. A rotating column is rotatably mounted inside the housing, and a support ring is fixedly mounted on the outer surface of the rotating column near its upper side. An inner groove is formed inside the rotating column, and multiple through slots extending to the outer surface of the rotating column are arranged in a circular array on the inner wall of the inner groove, with the through slots positioned above the support ring. An abutment block is slidably mounted inside the through slot, and a drive mechanism is provided inside the inner groove to simultaneously move the multiple abutment blocks outwards. A servo motor is mounted at the bottom of the housing, and the end of the servo motor's output shaft is connected to the bottom of the rotating column. A discharge port is formed on the bottom wall of the housing, and a scraper is mounted on the outer surface of the rotating column, with the lower surface of the scraper contacting the inner bottom wall of the housing.

[0007] Furthermore, the drive mechanism includes a conical block disposed inside the inner groove. Limiting grooves are formed on both sides of the inner wall of the inner groove, and limiting blocks are installed on both sides of the outer surface of the conical block, with each limiting block positioned within one of the two limiting grooves. A screw is rotatably mounted inside the inner groove, penetrating the interior of the conical block and threadedly connected thereto, with the top of the screw extending to the outer side of the rotating column. An inclined surface is provided at the end of the abutment block facing the conical block, engaging with the conical block.

[0008] Furthermore, a fixing block is installed on the top wall of the inner groove, and multiple sliding rods are installed in a circular array on the outer surface of the fixing block. The ends of the sliding rods are connected to the inner wall of the inner groove, and a sliding sleeve is slidably installed on the outer surface of the sliding rod. The bottom of the sliding sleeve is connected to the upper surface of the abutment block, and a spring is sleeved on the outer surface of the sliding rod. The two ends of the spring abut against the inner wall of the inner groove and the sliding sleeve, respectively.

[0009] Furthermore, multiple fixing plates are installed on the top of the cover, and a bearing roller is rotatably installed on the side of the fixing plate facing the axis of the cover. The highest point of the bearing roller is flush with the upper surface of the support ring.

[0010] Furthermore, a bracket is installed at the bottom of the cover corresponding to the material inlet, and a receiving box is provided on the upper surface of the bracket.

[0011] Furthermore, a handle is installed on the outer surface of the receiving box, and a rubber pad is provided on the outer surface of the handle.

[0012] Furthermore, a torsion bar is installed at the upper end of the screw.

[0013] Furthermore, multiple support columns are installed at the bottom of the cover, and anti-slip pads are provided at the bottom of the support columns.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model achieves the purpose of fixing by placing a fixed plate on the outside of the rotating column and placing it on the support ring, and then using a drive mechanism to simultaneously drive multiple abutment blocks to extend outward and abut against the inner side of the fixed plate. Furthermore, since the multiple abutment blocks move synchronously, the fixed plate achieves positioning while completing the fixing, eliminating the need for additional time for position adjustment, thereby improving the processing efficiency of the fixed plate.

[0016] 2. In this invention, the diameter of the support ring is much smaller than that of the fixed plate, which makes the processing area of ​​the fixed plate suspended. This allows some of the debris generated during drilling to fall directly into the housing. The debris remaining on the surface of the fixed plate can be poured directly into the housing when the fixed plate is removed after processing. When the servo motor drives the rotating column to rotate and adjust the drilling position of the fixed plate, it can simultaneously drive the scraper to clean the debris inside the housing and collect the debris from the discharge port. This reduces the difficulty of cleaning debris for workers and further improves processing efficiency. The adjustment of the drilling position of the fixed plate and the cleaning of debris share a single drive source and are carried out synchronously, thereby simplifying the overall mechanism and reducing costs.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-5 This utility model provides a quick positioning device for a truck axle mounting plate, including a cover 100. A rotating column 101 is rotatably mounted inside the cover 100, and a support ring 102 is fixedly mounted on the outer surface of the rotating column 101 near its upper side. An inner groove 103 is formed inside the rotating column 101, and multiple through slots 104 extending to the outer surface of the rotating column 101 are arranged in a circular array on the inner wall of the inner groove 103, with the through slots 104 positioned above the support ring 102. An abutment block 105 is slidably mounted inside the through slot 104, and a drive mechanism 200 is provided inside the inner groove 103 to simultaneously move the multiple abutment blocks 105 outwards. A servo motor 106 is mounted at the bottom of the cover 100, and the end of the output shaft of the servo motor 106 is connected to the bottom of the rotating column 101. The bottom wall of the cover 100 is provided with a discharge port 107, and a scraper 108 is installed on the outer surface of the rotating column 101. The lower surface of the scraper 108 is in contact with the inner bottom wall of the cover 100.

[0027] In use, the worker places the fixing plate on the outside of the rotating column 101 and on the surface of the support ring 102 to support the fixing plate. Then, the drive mechanism 200 simultaneously drives multiple abutment blocks 105 to extend outward and abut against the inner side of the fixing plate, thereby achieving the purpose of fixing. Since the multiple abutment blocks 105 move synchronously, the fixing plate is positioned at the same time as it is fixed, eliminating the need for additional time to adjust the position, thus improving the processing efficiency of the fixing plate.

[0028] At this time, the processing area of ​​the fixed plate is suspended, allowing some of the drilling debris to fall directly into the housing 100. The debris remaining on the surface of the fixed plate can be poured directly into the housing 100 when the fixed plate is removed after processing. When the servo motor 106 drives the rotating column 101 to rotate and adjust the drilling position of the fixed plate, it can simultaneously drive the scraper 108 to clean the debris inside the housing 100 and collect the debris from the discharge port 107. This reduces the difficulty of cleaning debris for workers and further improves processing efficiency. The adjustment of the drilling position of the fixed plate and the cleaning of debris share a single drive source and are carried out synchronously, thereby simplifying the overall mechanism and reducing costs.

[0029] Preferably, the drive mechanism 200 includes a conical block 201 disposed inside the inner groove 103. Limiting grooves 202 are formed on both sides of the inner wall of the inner groove 103, and limiting blocks 203 are installed on both sides of the outer surface of the conical block 201. The two limiting blocks 203 are respectively disposed within the two limiting grooves 202. A screw 204 is rotatably mounted inside the inner groove 103. The screw 204 passes through the interior of the conical block 201 and is threadedly connected to it. The top of the screw 204 extends to the outside of the rotating column 101. An inclined surface 205 is provided at the end of the abutment block 105 facing the conical block 201 to engage with the conical block 201.

[0030] The conical block 201 is limited by the limiting groove 202 and the limiting block 203, so that it can only slide in the vertical direction and cannot rotate. Therefore, when the screw 204 is rotated, the conical block 201 can be driven to rise and fall vertically under the drive of the threaded connection. When the conical block 201 contacts and presses against the inclined surface 205 of the abutment block 105, the abutment block 105 can be driven to move outward and abut against the inner side of the fixed plate to achieve the purpose of fixing.

[0031] Preferably, a fixing block 300 is installed on the top wall of the inner groove 103, and a plurality of sliding rods 301 are installed in a circular array on the outer surface of the fixing block 300. The ends of the sliding rods 301 are connected to the inner wall of the inner groove 103. A sliding sleeve 302 is slidably installed on the outer surface of the sliding rods 301. The bottom of the sliding sleeve 302 is connected to the upper surface of the abutment block 105. A spring 303 is sleeved on the outer surface of the sliding rods 301. The two ends of the spring 303 abut against the inner wall of the inner groove 103 and the sliding sleeve 302, respectively.

[0032] When the abutment block 105 is squeezed and moves outward, it causes the sliding sleeve 302 to slide on the sliding rod 301. During the sliding process, the sliding sleeve 302 compresses the spring 303 to store force. After the fixed plate is processed, the screw 204 is turned in the opposite direction to drive the conical block 201 to descend. At this time, the compressed spring 303 releases its elastic force to push the sliding sleeve 302 to slide on the sliding rod 301, and causes the abutment block 105 to retract and reset inward, separating it from the fixed plate, so that the fixed plate can be removed from the rotating column 101.

[0033] Preferably, a plurality of fixing plates 400 are installed on the top of the cover 100, and a bearing roller 401 is rotatably installed on the side of the fixing plate 400 facing the axis of the cover 100. The highest point of the bearing roller 401 is flush with the upper surface of the support ring 102.

[0034] Since the processing area of ​​the fixed disk is suspended, and drilling will exert downward pressure on the fixed disk, the support roller 401 can provide support for the bottom of the fixed disk, avoiding slight deformation caused by pressure. When the servo motor 106 drives the fixed disk to rotate and adjust the processing position, the support roller 401 can rotate with the fixed disk, thereby reducing the friction force generated on the bottom of the fixed disk and ensuring the structural integrity of the fixed disk.

[0035] Preferably, a bracket 500 is installed at the bottom of the cover 100 corresponding to the discharge port 107, and a receiving box 501 is provided on the upper surface of the bracket 500.

[0036] The debris swept off from the discharge port 107 can fall directly into the receiving box 501. When the receiving box 501 has collected a certain amount of debris, it can be removed and processed.

[0037] Preferably, a handle 600 is installed on the outer surface of the receiving box 501, and a rubber pad is provided on the outer surface of the handle 600.

[0038] The handle 600 facilitates the pulling of the receiving box 501 out of the bracket 500, and the rubber pad on its surface prevents slippage.

[0039] Preferably, a torsion bar 700 is installed at the upper end of the screw 204.

[0040] The torsion bar 700 provides a hand support point, facilitating the rotation of the screw 204.

[0041] Preferably, the bottom of the cover 100 is provided with a plurality of support columns 800, and the bottom of the support columns 800 is provided with anti-slip pads 801.

[0042] The support column 800 provides support for the housing 100, provides installation space for the servo motor 106 and the bracket 500, and the anti-slip pad 801 can prevent slipping and improve the stability of the overall structure.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
