Description
Technical Field
[0001] The invention relates to the technical field of bearing processing equipment, and in particular to a tooling for loading and unloading truss bearings. Background Art
[0002] In modern industrial production, especially in the field of mechanical manufacturing, truss bearings are widely used. However, in the production and processing of truss bearings, loading and unloading has always been a more difficult problem. The traditional loading and unloading method of truss bearings usually relies on manual operation, which is not only inefficient, but also difficult to ensure accuracy, prone to errors, and increases production costs and time costs. In large-scale production lines, this inefficient operation method seriously affects the overall production progress and cannot respond quickly to market demand. At the same time, since different production tasks may require the processing of tapered bearings of various specifications, the outer raceway of the bearing is ground by grabbing the bearing with a claw or hooking the bearing with a tooling. When producing tapered roller bearings, because the bearing raceway is tapered and has a large diameter and heavy weight, it cannot be grabbed, and the existing loading and unloading tooling has poor versatility and applicability. It is often necessary to frequently replace the tooling for bearings of different specifications, which is not only cumbersome, but also greatly increases the tooling cost and time cost.
[0003] In addition, in complex working environments, the existing clamping devices lack stability and reliability in clamping bearings, which can easily cause bearings to slip or shift, affecting product quality and production safety. Moreover, the maintenance and upkeep of the clamping device is difficult, and the replacement of the clamping block is also extremely inconvenient, making it difficult to quickly adjust according to different processing requirements. In order to solve the above problems, improve the efficiency, accuracy, versatility and stability of loading and unloading truss bearings, while reducing costs and improving production flexibility, the present invention "a tooling for loading and unloading truss bearings" came into being. Summary of the invention
[0004] In view of the deficiencies in the prior art, the present invention adopts the following technical solution to solve the technical problems: a tool for loading and unloading truss bearings, comprising: a connecting frame; a driving device, the top of the driving device is fixedly connected to the top of the connecting frame; an adjusting device, the top of the adjusting device is rotatably connected to the bottom of the driving device; a clamping device, the top of the clamping device is fixedly connected to the bottom of the adjusting device; the driving device comprises a cross bar, the outer wall of the cross bar is symmetrically fixedly connected with a connecting plate, the bottom end of the cross bar is fixedly connected with a telescopic rod, the bottom end of the telescopic rod is fixedly connected with a connecting block, the outer wall of the connecting block is symmetrically and rotatably connected with a pull rod, and the inner wall of the connecting plate is rotatably connected with a clamping rod.
[0005] The present invention is further configured such that the top end of the crossbar is fixedly connected to the bottom end of the connecting frame, and the end of the pull rod away from the connecting block is rotatably connected to the outer wall of the clamping rod. The telescopic rod on the crossbar performs telescopic movement. When the telescopic rod is extended or shortened, it drives the connecting block to move, so that the pull rod rotatably connected thereto pulls or pushes the clamping rod to rotate around the connecting plate, thereby realizing the initial driving of the tooling.
[0006] The present invention is further configured such that the adjustment device comprises a sliding plate, the top end of the sliding plate is fixedly connected to a fixed plate, the inner wall of the fixed plate is rotatably connected to an adjustment screw, the outer wall of the fixed plate is fixedly connected to a motor via a frame, and the top end of the fixed plate is fixedly connected to a fixed block. The inner wall of the fixed block is rotatably connected to the bottom end of the clamping rod, the adjustment screw penetrates the fixed plate and extends to the outside of the fixed plate, and the output end of the motor is fixedly connected to the outer wall of the adjustment screw.
[0007] The present invention is further configured such that the inner wall of the sliding plate is slidably connected with a sliding block, the bottom end of the sliding block is fixedly connected to the outer wall of the clamping device, and the inner wall of the sliding block is threadedly connected to the outer wall of the adjusting screw. The inner wall of the sliding block is threadedly connected to the adjusting screw, and the rotation of the adjusting screw causes the sliding block to slide on the sliding plate between the fixed blocks, and the clamping device is driven to perform fine position adjustment through the connection of the connecting column, thereby facilitating the clamping and fixing of tapered bearings of different sizes.
[0008] The present invention is further configured such that the clamping device comprises a connecting column, the outer wall of the connecting column is fixedly connected to a limit block, the bottom end of the connecting column is fixedly connected to a fixed cone block, the outer wall of the connecting column is slidably connected to a sliding cone block, and a clamping block is arranged outside the connecting column. According to the outer taper of the clamping block, the outer ring raceway of the tapered bearing is fitted.
[0009] The present invention is further configured such that the bottom end of the fixed cone block is fixedly connected with a resisting rod, the inner wall of the clamping block is slidably connected with a sliding rod, the outer wall of the sliding rod is fixedly connected with a stopper, and the top end of the connecting column is fixedly connected with the bottom end of the sliding block.

The limiting screw is disengaged from the limiting groove, and the sliding cone block is pushed to slide downward on the outer wall of the stop rod under the action of the reset spring, and the sliding cone block squeezes the stopper downward to slide again, so that the fixed cone block is no longer restricted. At this time, without the limit of the stopper, the extrusion block can be directly removed.
[0011] The beneficial effects of the present invention are as follows: 1. The present invention provides a driving device, and through precise control of the driving device, it is possible to achieve preliminary positioning and movement of the tooling, so that the tooling can quickly approach the truss bearing to be operated, which greatly improves the work efficiency, facilitates rapid response on a large-scale production line, and reduces the preparation time for loading and unloading.
[0012] 2. The present invention provides an adjustment device that can perform fine position adjustment according to tapered bearings of different sizes, thereby enhancing the versatility and applicability of the tooling. Since the inner wall of the sliding block is threadedly connected to the adjusting screw, the rotation of the adjusting screw causes the sliding block to slide on the sliding plate between the fixed blocks.

Even in a complex working environment, it can effectively prevent the bearing from slipping or shifting during the clamping process.

Example
[0019] See also Figure 1 - Figure 8 The present invention provides a technical solution: a tool for loading and unloading truss bearings, comprising: a connecting frame 1; a driving device 2, the top of the driving device 2 is fixedly connected to the top of the connecting frame 1; an adjusting device 3, the top of the adjusting device 3 is rotatably connected to the bottom of the driving device 2; a clamping device 4, the top of the clamping device 4 is fixedly connected to the bottom of the adjusting device 3; the driving device 2 comprises a cross bar 21, the outer wall of the cross bar 21 is symmetrically fixedly connected with a connecting plate 23, the bottom end of the cross bar 21 is fixedly connected with a telescopic rod 22, the bottom end of the telescopic rod 22 is fixedly connected with a connecting block 26, the outer wall of the connecting block 26 is symmetrically rotatably connected with a pull rod 25, and the inner wall of the connecting plate 23 is rotatably connected with a clamping rod 24.
[0020] The top of the crossbar 21 is fixedly connected to the bottom of the connecting frame 1, and the end of the pull rod 25 away from the connecting block 26 is rotatably connected to the outer wall of the clamping rod 24. The telescopic rod 22 fixedly connected to the crossbar 21 performs telescopic movement. When the telescopic rod 22 is extended or shortened, the connecting block 26 fixedly connected thereto is driven to move, so that the pull rod 25 rotatably connected thereto pulls or pushes the clamping rod 24 to rotate around the connecting plate 23, thereby realizing the preliminary driving of the tooling.
[0021] The adjusting device 3 includes a sliding plate 35, the top of which is fixedly connected to a fixed plate 32, the inner wall of which is rotatably connected to an adjusting screw 33, the outer wall of which is fixedly connected to a motor 36 via a frame, and the top of which is fixedly connected to a fixing block 31. The inner wall of the fixing block 31 is rotatably connected to the bottom end of the clamping rod 24, the adjusting screw 33 penetrates the fixing plate 32 and extends to the outside of the fixing plate 32, and the output end of the motor 36 is fixedly connected to the outer wall of the adjusting screw 33.
[0022] The inner wall of the sliding plate 35 is slidably connected with a sliding block 34, the bottom end of the sliding block 34 is fixedly connected to the outer wall of the clamping device 4, and the inner wall of the sliding block 34 is threadedly connected to the outer wall of the adjusting screw 33. The motor 36 is started to drive the fixedly connected adjusting screw 33 to rotate. Since the inner wall of the sliding block 34 is threadedly connected to the adjusting screw 33, the rotation of the adjusting screw 33 causes the threaded sliding block 34 to slide the sliding plate 35 between the fixed blocks 31.
[0023] The clamping device 4 includes a connecting column 41, the outer wall of the connecting column 41 is fixedly connected to a limit block 42, the bottom end of the connecting column 41 is fixedly connected to a fixed cone block 44, the outer wall of the connecting column 41 is slidably connected to a sliding cone block 45, and a clamping block 43 is arranged outside the connecting column 41. According to the outer taper of the clamping block 43, the outer ring raceway of the tapered bearing is fitted.
[0024] The bottom end of the fixed cone block 44 is fixedly connected with a stopper rod 412, the inner wall of the clamping block 43 is slidably connected with a slide rod 47, the outer wall of the slide rod 47 is fixedly connected with a stopper 46, and the top of the connecting column 41 is fixedly connected with the bottom end of the sliding block 34. The outer wall of the stopper 46 is fixedly connected with a push spring 48, and one end of the push spring 48 away from the stopper 46 is fixedly connected with the inner wall of the fixed cone block 44, the outer wall of the stopper 46 is slidably connected with the inner wall of the fixed cone block 44, and the outer wall of the fixed cone block 44 is slidably connected with the inner wall of the clamping block 43. The fixed cone block 44 enters the interior of the clamping block 43 and squeezes the outer walls of the blocks 46 at both ends, so that the blocks 46 push the fixedly connected slide rod 47 to slide on the inner wall of the clamping block 43 until the fixed cone block 44 can slide into the interior of the clamping block 43. Under the action of the push spring 48, the block 46 is pushed to get stuck on the top of the clamping block 43, and the clamping block 43 is fixed through the action of the block 46 and the stop rod 412.
[0025] The outer wall of the connecting column 41 is provided with a limiting groove 410, the inner wall of the sliding cone block 45 is threadedly connected with a limiting screw 411, the top of the sliding cone block 45 is fixedly connected with a return spring 49, the outer wall of the limiting screw 411 is slidably connected with the inner wall of the limiting groove 410, and the end of the return spring 49 away from the sliding cone block 45 is fixedly connected with the outer wall of the limiting block 42. The limiting screw 411 on the inner wall of the sliding cone block 45 is rotated to make the limiting screw 411 disengage from the inner wall of the limiting groove 410, and the fixedly connected sliding cone block 45 is pushed to slide downward on the outer wall of the stop rod 412 under the action of the return spring 49, and the stop block 46 is pressed downward to slide again, so that the clamping block 43 can be directly removed without limiting the fixed cone block 44 and the stop block 46.
[0026] Working principle: When in use, the connecting frame 1 is connected to the external truss to provide support and connection foundation for the entire tooling. The telescopic rod 22 on the crossbar 21 is started to telescope through the driving device 2. When the telescopic rod 22 is extended or shortened, it drives the connecting block 26 to move, so that the pull rod 25 rotatably connected thereto pulls or pushes the clamping rod 24 to rotate around the connecting plate 23, thereby realizing the preliminary drive of the tooling. When the clamping rod 24 rotates, the adjustment device 3 is moved by driving the connection of the adjustment fixing block 31 at the bottom, and the clamping device 4 at the bottom of the adjustment device 3 is moved to clamp or release the tapered bearing; Through the adjusting device 3, according to the size of the tapered bearing, the motor 36 is started to drive the adjusting screw 33 to rotate. Since the inner wall of the sliding block 34 is threadedly connected with the adjusting screw 33, the rotation of the adjusting screw 33 causes the sliding block 34 to slide on the sliding plate 35 between the fixed block 31, and drives the clamping device 4 to perform fine adjustment of the position through the connection of the connecting column 41, so as to facilitate the clamping and fixing of tapered bearings of different sizes; When the clamping device 4 is working, according to the outer taper of the clamping block 43, the outer ring raceway of the tapered bearing is fitted, and the fixed cone block 44 is set. When the clamping block 43 needs to be installed, the clamping block 43 is inserted into the outside of the stop rod 412. As the fixed cone block 44 enters the inside of the clamping block 43, it squeezes the stoppers 46 at both ends, so that the stoppers 46 push the sliding rod 47 to slide on the inner wall of the clamping block 43 until the fixed cone block 44 can slide into the inside of the clamping block 43. As the stop rod 412 contacts the bottom end of the inner wall of the clamping block 43, under the action of the push spring 48, it pushes the stopper 46 to get stuck on the top of the clamping block 43. Through the action of the stopper 46 and the stop rod 412, the clamping block 43 is fixed, and the stopper 46 is limited to prevent the tapered bearing from rotating when it is fixed. When it is necessary to loosen the fixation of the clamping block 43, the limiting screw 411 on the inner wall of the sliding cone block 45 is rotated to make the limiting screw 411 disengage from the limiting groove 410, and the sliding cone block 45 is pushed to slide downward on the outer wall of the stop rod 412 under the action of the reset spring 49. As it moves downward, the sliding cone block 45 squeezes the stop block 46 downward and slides again, so that the fixed cone block 44 is no longer restricted until the sliding cone block 45 contacts the top of the fixed cone block 44. At this time, without the limitation of the stop block 46, the clamping block 43 can be directly removed, which is convenient for replacing the clamping block 43. During the loading and unloading process of the truss bearing, the driving device 2 first moves the tooling to the bearing position roughly, and the adjusting device 3 performs fine positioning. Finally, the clamping device 4 completes the clamping and loosening operations of the bearing, thereby realizing efficient and accurate loading and unloading work.
