Description

Technical Field

[0001] The present invention relates to the technical field of bolster processing, and particularly relates to a positioning and processing tooling for a bolster. Background Art

[0002] With the continuous development of China's economy, the logistics market in China has been continuously promoted, and the demand for railway freight cars has become increasingly strong. Correspondingly, with the increase in the demand and usage of railway freight cars, new requirements have been put forward for the production and processing of some parts of railway freight cars, requiring lower processing costs and higher production efficiency for the parts.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: When processing the bolster, it is necessary to fix the bolster on the tooling. In this process, a fixture is required to fix the bolster. However, when processing the plane of the bolster, when the staff fixes the bolster, it is necessary to fix the bolster through the arc surface of the bolster. However, when the existing fixture fixes an object with an arc surface, the fixing difficulty is relatively large, and it is easy to shake during the processing, thereby reducing the fixing stability. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a positioning and processing tooling for a bolster.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A positioning and processing tooling for a bolster, including a base, two symmetrically arranged support members are fixedly provided on the upper surface of the base, placing grooves are respectively opened on the upper surfaces of the two support members, a bolster body is jointly placed in the two placing grooves, and a fixing device for fixing the bolster body is arranged on the base. The fixing device includes a fixing component and a driving component.

[0006] By adopting the above technical solutions, when the staff needs to process the bolster body, the staff needs to place the bolster body in the placing groove. Subsequently, the staff starts the fixing device to fix the bolster body. In this process, the fixing device can fix the bolster body through the arc surface on the bolster body, thereby reducing the probability of shaking during the processing of the bolster body, and thus improving the stability of the device.

[0007] Furthermore, the fixing component includes a support base fixedly arranged on the upper surface of the base, a fixing disk fixedly arranged on the side wall of the support base, and a rotating gear rotatably arranged on the side wall of the fixing disk away from the support base. A plurality of sliding grooves are formed in the side wall of the fixing disk away from the support base, and a plurality of driving grooves penetrate through the side wall of the rotating gear away from the fixing disk. The fixing component further includes a sliding rod slidably arranged in the sliding groove, a driving rod slidably arranged in the driving groove, and a fixing piece fixedly arranged on the side wall of the sliding rod. The driving rod is fixedly connected with the sliding rod.

[0008] Furthermore, a rotating groove penetrates through the side wall of one of the support pieces. The driving component includes a rotating rod rotatably arranged in the rotating groove, a worm fixedly arranged on the side wall of the rotating rod, a driving gear rotatably arranged on the side wall of the fixing disk away from the support base, and a turbine installed on the side wall of the driving gear away from the fixing disk. The driving gear meshes with the rotating gear, and the turbine meshes with the worm.

[0009] By adopting the above technical solution, when the staff needs to fix the carrying saddle body, the staff needs to rotate the rotating rod, so that the worm rotates under the action of the rotating rod, and then the turbine rotates under the action of the worm, and then the driving gear rotates synchronously with the turbine under the action of the turbine, so that the rotating gear meshing with the driving gear rotates under the action of the driving gear, and then the driving rod slidably connected with the driving groove rotates under the action of the rotating gear, so that the sliding rod slides along the sliding groove under the action of the driving rod, and then the fixing piece moves under the action of the sliding rod, so that a plurality of fixing pieces abut against the arc surface of the carrying saddle body, and then the carrying saddle body is fixed. During this process, the side of the fixing piece away from the sliding rod matches the arc surface of the carrying saddle body, thereby reducing the probability of shaking during the processing of the carrying saddle body, and improving the stability of the device.

[0010] Furthermore, a connecting frame with an L-shaped cross section is fixedly arranged on the upper surface of the base. A cylinder is fixedly arranged on the upper surface of the connecting frame. The piston rod of the cylinder penetrates through the connecting frame, and a fixing block is fixedly arranged at the end of the piston rod of the cylinder.

[0011] By adopting the above technical solution, before the staff needs to fix the carrying saddle body through the fixing device, the staff needs to start the cylinder, so that the piston rod of the cylinder moves downward, and then the fixing block moves downward under the action of the piston rod of the cylinder, and then the fixing block abuts against the upper surface of the carrying saddle body. Subsequently, the staff starts the fixing device to fix the carrying saddle body. During this process, the probability of shaking during the processing of the carrying saddle body is further reduced, and the stability of the device is improved.

[0012] Further, a motor is fixedly arranged on the side wall of one of the support members. The output shaft of the motor is fixedly connected to the rotating rod. A receiving groove is formed in the inner bottom wall of the placement groove. A limit switch is installed in the receiving groove. The limit switch is electrically connected to the motor through a controller.

[0013] By adopting the above technical solution, when the fixed block abuts against the upper surface of the bearing saddle body, the placement plate slides downward under the action of the bearing saddle body, and then the placement plate gradually approaches and finally abuts against the limit switch, so as to activate the limit switch by the bearing saddle body. At this time, the limit switch activates the motor through the controller, and then the output shaft of the motor rotates, so that the rotating rod rotates under the action of the output shaft of the motor. In this process, there is no need for the staff to manually activate the fixing device, thereby reducing the work difficulty of the staff.

[0014] Further, a placement plate is slidably arranged in the placement groove. Two symmetrically arranged first springs are fixedly arranged on the bottom surface of the placement plate. The other ends of the two first springs are fixedly arranged on the inner bottom wall of the placement groove.

[0015] By adopting the above technical solution, when the bearing saddle body is separated from the placement groove, the placement plate resets under the action of the first spring, and then the limit switch resets. In this process, the difficulty for the staff to reset the limit switch and the placement plate is reduced, thereby reducing the work difficulty of the staff.

[0016] Further, two symmetrically arranged limit holes are formed in the side wall of the fixed disk. Limit members are rotatably arranged in the two limit holes. The two limit members are respectively fixedly connected to the rotating gear and the driving gear.

[0017] By adopting the above technical solution, it can be seen that Figure 3 the diameter of one end of the limit rod close to the driving gear is smaller than that of the end far from the driving gear, so as to limit the driving gear and the rotating gear, thereby reducing the probability of the driving gear and the rotating gear being separated from the fixed disk, and further improving the stability of the device.

[0018] Further, an installation groove is formed in the arc surface of one of the fixing members. A pressure detector is installed in the installation groove. The pressure detector is electrically connected to the motor through a controller.

[0019] By adopting the above technical solution, when the fixing member abuts against the arc surface of the bearing saddle body, the pressure detector is activated, and then the pressure detector controls the motor to turn off through the controller, thereby reducing the probability of the bearing saddle body being damaged by the fixing member.

[0020] Further, a connecting rod is fixedly arranged on the side wall of the driving gear away from the fixed disk, the other end of the connecting rod is fixedly connected to the turbine, and the axes of the turbine, the connecting rod and the driving gear coincide with each other.

[0021] By adopting the above technical solution, the connecting rod increases the distance between the turbine and the driving gear, thereby reducing the probability of collision between the worm and the driving gear, and improving the stability of the device.

[0022] Further, a first rubber pad is fixedly arranged on the bottom surface of the fixed block, and second rubber pads are fixedly arranged on the arc surfaces of the plurality of fixing members.

[0023] By adopting the above technical solution, the first rubber pad and the second rubber pad reduce the probability of damage to the bearing saddle body caused by the fixing members and the fixed block.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. In the present application, when the staff needs to process the bearing saddle body, the staff needs to place the bearing saddle body in the placement groove. Subsequently, the staff starts the fixing device to fix the bearing saddle body. During this process, the fixing device can fix the bearing saddle body through the arc surface on the bearing saddle body, thereby reducing the probability of shaking during the processing of the bearing saddle body, and improving the stability of the device;

[0026] 2. In the present application, when the staff needs to fix the bearing saddle body, the staff needs to rotate the rotating rod, so that the worm rotates under the action of the rotating rod, so that the turbine rotates under the action of the worm, so that the driving gear rotates synchronously with the turbine under the action of the turbine, so that the rotation meshing with the driving gear rotates under the action of the driving gear, so that the driving rod slidably connected to the driving groove rotates under the action of the rotating gear, so that the sliding rod slides along the sliding groove under the action of the driving rod, so that the fixing member moves under the action of the sliding rod, so that the plurality of fixing members abut against the arc surface of the bearing saddle body, thereby fixing the bearing saddle body. During this process, the side of the fixing member away from the sliding rod matches the arc surface of the bearing saddle body, thereby reducing the probability of shaking during the processing of the bearing saddle body, and improving the stability of the device;

[0027] 3. In this application, before the staff needs to fix the carrier saddle body through the fixing device, the staff needs to start the cylinder, so that the piston rod of the cylinder moves downward, and then the fixing block moves downward under the action of the piston rod of the cylinder, and then the fixing block presses against the upper surface of the carrier saddle body. Subsequently, the staff starts the fixing device to fix the carrier saddle body. During this process, the probability of the carrier saddle body shaking during processing is further reduced, thereby improving the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0035] As Figures 1-5As shown in the figure, an embodiment of the present application discloses a positioning and machining tool for a bearing saddle, including a base 1, a support member 11, a bearing saddle body 12, a fixing assembly 3, a driving assembly 4, a connecting frame 5, a cylinder 51, a fixing block 52, a motor 6, a limit switch 61, a placing plate 7, a first spring 71, a limiting member 8, and a pressure detector 9. The base 1 is a rectangular plate-like structure, and the support member 11 is a cuboid structure. There are two support members 11, which are symmetrically arranged on the upper surface of the base 1. Placing grooves 2 are formed on the upper surfaces of the two support members 11, and the bearing saddle body 12 is placed in the two placing grooves 2. A fixing device is arranged on the base 1 for fixing the bearing saddle body 12, and the fixing device includes a fixing assembly 3 and a driving assembly 4.

[0036] When a worker needs to machine the bearing saddle body 12, the worker needs to place the bearing saddle body 12 in the placing groove 2. Subsequently, the worker starts the fixing device to fix the bearing saddle body 12. During this process, the fixing device can fix the bearing saddle body 12 through the arc surface on the bearing saddle body 12, thereby reducing the probability of shaking during the machining of the bearing saddle body 12 and improving the stability of the device.

[0037] The fixing assembly 3 includes a support base 31, a fixing disk 32, a rotating gear 33, a sliding rod 34, a driving rod 35, and a fixing member 36. The support base 31 is fixedly arranged on the upper surface of the base 1. The fixing disk 32 is a circular plate-like structure with a horizontal axis, and the fixing disk 32 is fixedly arranged on the side wall of the support base 31. A plurality of sliding grooves 21 are formed on the side wall of the fixing disk 32 away from the support base 31. The rotating gear 33 is rotatably arranged on the side wall of the fixing disk 32 away from the support base 31, and its axis coincides with the axis of the fixing disk 32. A plurality of driving grooves 22 penetrate through the side wall of the rotating gear 33 away from the fixing disk 32. A plurality of sliding rods 34 are respectively slidably arranged in the plurality of sliding grooves 21, and a plurality of driving rods 35 are respectively slidably arranged in the plurality of driving grooves 22. The driving rod 35 and the sliding rod 34 are fixedly connected to each other. A plurality of fixing members 36 are respectively fixedly arranged on the side walls of the sliding rods 34 for fixing the bearing saddle body 12.

[0038] A rotating groove 23 penetrates through the side wall of one of the support members 11. The driving assembly 4 includes a rotating rod 41, a worm 42, a driving gear 43, and a turbine 44. The rotating rod 41 is a circular rod-like structure with a horizontal axis, and the rotating rod 41 is rotatably arranged in the rotating groove 23. The worm is fixedly arranged on the side wall of the rotating rod 41, and its axis coincides with the axis of the rotating rod 41. The driving gear 43 is rotatably arranged on the side wall of the fixing disk 32 away from the support base 31, and its axis is horizontal. The driving gear 43 meshes with the rotating gear 33. The turbine 44 is installed on the side wall of the driving gear 43 away from the fixing disk 32, and its axis coincides with the axis of the driving gear 43. The turbine 44 meshes with the worm 42.

[0039] When the staff needs to fix the carrier saddle body 12, the staff needs to rotate the rotating rod 41, so that the worm 42 rotates under the action of the rotating rod 41, so that the turbine 44 rotates under the action of the worm 42, and then the driving gear 43 rotates synchronously with the turbine 44 under the action of the turbine 44. Thus, the rotating gear meshing with the driving gear 43 rotates under the action of the driving gear 43, and then the driving rod 35 slidably connected to the driving groove 22 rotates under the action of the rotating gear 33, so that the sliding rod 34 slides along the sliding groove 21 under the action of the driving rod 35, and then the fixing member 36 moves under the action of the sliding rod 34, so that a plurality of fixing members 36 abut against the arc surface of the carrier saddle body 12, and then the carrier saddle body 12 is fixed. During this process, the side of the fixing member 36 away from the sliding rod 34 matches the arc surface of the carrier saddle body 12, thereby reducing the probability of shaking during the processing of the carrier saddle body 12, and thus improving the stability of the device.

[0040] The cross-section of the connecting frame 5 is L-shaped, and the connecting frame 5 is fixedly arranged on the upper surface of the base 1. The air cylinder 51 is fixedly arranged on the upper surface of the connecting frame 5, and the axis of its piston rod is vertical, and the piston rod of the air cylinder 51 penetrates and is connected. The fixing block 52 is fixedly arranged at the end of the piston rod of the air cylinder 51, and it is used to fix the carrier saddle body 12.

[0041] Before the staff needs to fix the carrier saddle body 12 through the fixing device, the staff needs to start the air cylinder 51, so that the piston rod of the air cylinder 51 moves downward, so that the fixing block 52 moves downward under the action of the piston rod of the air cylinder 51, and then the fixing block 52 abuts against the upper surface of the carrier saddle body 12. Subsequently, the staff starts the fixing device to fix the carrier saddle body 12. During this process, the probability of shaking during the processing of the carrier saddle body 12 is further reduced, and thus the stability of the device is improved.

[0042] The motor 6 is fixedly arranged on the side wall of one of the support members 11, and the axis of its piston rod coincides with the axis of the rotating rod 41, and the output shaft of the motor 6 is fixedly connected to the rotating rod 41. A receiving groove 24 is opened on the inner bottom wall of the placing groove 2, and the limit switch 61 is installed in the receiving groove 24, and the limit switch 61 is electrically connected to the motor 6 through a controller.

[0043] When the fixing block 52 abuts against the upper surface of the carrier saddle body 12, the placing plate 7 slides downward under the action of the carrier saddle body 12, so that the placing plate 7 gradually approaches and finally abuts against the limit switch 61, so that the carrier saddle body 12 activates the limit switch 61. At this time, the limit switch 61 starts the motor 6 through the controller, so that the output shaft of the motor 6 rotates, so that the rotating rod 41 rotates under the action of the output shaft of the motor 6. During this process, there is no need for the staff to manually start the fixing device, thereby reducing the work difficulty of the staff.

[0044] The placing plate 7 is in a rectangular plate structure and is slidably arranged in the placing groove 2. There are two first springs 71. One ends of the two first springs 71 are symmetrically arranged on the bottom surface of the placing plate 7, and the other ends of the two first springs 71 are fixedly arranged on the inner bottom wall of the placing groove 2.

[0045] When the carrier saddle body 12 is separated from the placing groove 2, the placing plate 7 is reset under the action of the first spring 71, and then the limit switch 61 is reset. In this process, the difficulty for the staff to reset the limit switch 61 and the placing plate 7 is reduced, thus reducing the working difficulty of the staff.

[0046] Two symmetrically arranged limit holes 25 are formed on the side wall of the fixed disk 32. There are two limit members 8 which are respectively rotatably arranged in the two limit holes 25, and the two limit members 8 are respectively fixed to the rotating gear 33 and the driving gear 43.

[0047] From Figure 3 it can be obtained that the diameter of one end of the limit rod close to the driving gear 43 is smaller than that of the end far from the driving gear 43. Thus, the limit rod limits the driving gear 43 and the rotating gear 33, thereby reducing the probability that the driving gear 43 and the rotating gear 33 are separated from the fixed disk 32, and further improving the stability of the device.

[0048] An installation groove 26 is formed on the arc surface of one of the fixing members 36. The pressure detector 9 is installed in the installation groove 26, and the pressure detector 9 is electrically connected to the motor 6 through a controller.

[0049] When the fixing member 36 abuts against the arc surface of the carrier saddle body 12, the pressure detector 9 is activated, and then the pressure detector 9 controls the motor 6 to turn off through the controller, thereby reducing the probability that the fixing member 36 causes damage to the carrier saddle body 12.

[0050] To improve the stability of the device, a connecting rod 91 is fixedly arranged on the side wall of the driving gear 43 far from the fixed disk 32, and the other end of the connecting rod 91 is fixed to the turbine 44. The axes of the turbine 44, the connecting rod 91 and the driving gear 43 coincide with each other. The connecting rod 91 increases the distance between the turbine 44 and the driving gear 43, thereby reducing the probability that the worm 42 collides with the driving gear 43, and further improving the stability of the device.

[0051] To reduce the probability of damaging the carrier saddle body 12, a first rubber pad is fixedly arranged on the bottom surface of the fixed block 52, and second rubber pads are fixedly arranged on the arc surfaces of the plurality of fixing members 36. The first rubber pad and the second rubber pad reduce the probability that the fixing member 36 and the fixed block 52 cause damage to the carrier saddle body 12.

[0052] In this embodiment, the working principle of a positioning and machining tool for a bolster is as follows: When workers need to machine the bolster body 12, they need to place the bolster body 12 in the placement groove 2. Subsequently, the worker needs to rotate the rotating rod 41, so that the worm 42 rotates under the action of the rotating rod 41, and then the turbine 44 rotates under the action of the worm 42, and then the driving gear 43 rotates synchronously with the turbine 44 under the action of the turbine 44. Thus, the rotating gear meshing with the driving gear 43 rotates under the action of the driving gear 43, and then the driving rod 35 slidably connected to the driving groove 22 rotates under the action of the rotating gear 33, so that the sliding rod 34 slides along the sliding groove 21 under the action of the driving rod 35, and then the fixing member 36 moves under the action of the sliding rod 34, so that a plurality of fixing members 36 abut against the arc surface of the bolster body 12, and then the bolster body 12 is fixed. During this process, the side of the fixing member 36 away from the sliding rod 34 matches the arc surface of the bolster body 12, thereby reducing the probability of shaking during the machining of the bolster body 12, and thus improving the stability of the device.

[0053] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
