Description

Technical Field

[0001] This utility model belongs to the field of laser cladding equipment, specifically relating to a positioning and calibration fixture for laser cladding of jacks. Background Technology

[0002] Laser cladding is a process in which a cladding material is added to the surface of a substrate, and then a high-energy-density laser beam is used to fuse the material with a thin layer on the substrate surface. When cladding shaft-type workpieces, one end of the roller is typically clamped and fixed, while two support wheels support the roller in the middle. Different roller models have different diameters, requiring adjustment of the support wheels. Existing positioning and calibration fixtures can only adjust the spacing between the support wheels and the overall height. However, after prolonged operation, due to equipment wear and loose parts, slight height differences may still exist between the different support wheels even after overall height adjustment. Existing calibration fixtures cannot adjust individual support wheels, easily leading to an imbalance in the support height on both sides of the roller, affecting the cladding quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model aims to provide a positioning and calibration fixture for laser cladding of jacks. This device can stably support and position the roller body, and can not only adjust the height and spacing of the support wheels on both sides of the roller body synchronously, but also fine-tune individual support wheels, thereby significantly improving the cladding quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A positioning and calibration fixture for laser cladding of a jack includes a cladding platform, a clamping assembly, and a positioning assembly. The clamping assembly is installed on the left side of the cladding platform, and the positioning assembly is installed on the right side of the cladding platform. The end of the roller is fixed to the clamping assembly, and the middle of the roller is supported on the positioning assembly. The positioning assembly includes a bracket, a lifting platform, and multiple sets of support wheels. The lifting platform is slidably mounted on the bracket and connected to a lifting drive assembly on the bracket. The support wheels are mounted on the lifting platform along the length of the roller. Each support wheel includes two rollers symmetrically arranged on both sides of the roller below. The rollers are mounted on wheel seats, and the bottom of the wheel seats is mounted on the actuating end of a corresponding fine-tuning assembly via a pressure sensor. The fine-tuning assembly is fixed to a corresponding sliding plate. Two transverse plates are movably arranged on the lifting plates parallel to the roller on both sides. The two transverse plates are slidably mounted on the lifting platform and driven synchronously to move away from or towards each other by a synchronous adjustment assembly. The sliding plates are horizontally mounted on the corresponding transverse plates and can be adjusted left and right.

[0006] Preferably, the lifting drive assembly includes a first screw and a first motor. The first screw is vertically mounted on the bracket and its end is poweredly connected to the first motor. The lifting platform is threaded onto the first screw.

[0007] Preferably, the synchronous adjustment assembly includes a second screw and two connecting rod assemblies. The second screw is mounted on a lifting platform between two transverse plates with parallel rollers. A rotating handwheel is installed at the end of the second screw. A first sliding groove is opened in the front-back direction on the lifting platform. The bottom of the transverse plate is slidably installed in the first sliding groove. The two connecting rod assemblies are symmetrically installed on the positive and negative threads on both sides of the second screw. The connecting rod assembly includes a first connecting rod and a second connecting rod. A moving block is threaded on the second screw. The two connecting rods are arranged in an "eight" shape on both sides of the second screw. One end of the two connecting rods is rotatably connected to the moving block, and the other end is rotatably connected to the corresponding transverse plate.

[0008] Preferably, the transverse sliding plate has a second sliding groove horizontally opened on the left and right, the bottom of the sliding plate is slidably locked in the second sliding groove, and a locking bolt is vertically installed on the sliding plate, with the end of the locking bolt abutting against the transverse sliding plate.

[0009] Preferably, the fine-tuning assembly includes a fine-tuning seat and a vertical moving block. The fine-tuning seat is fixedly mounted on a sliding plate, and the vertical moving block is vertically slidably mounted on the fine-tuning seat. The vertical moving block has a mounting groove in the middle, and a pressure sensor is installed inside the mounting groove. The wheel seat is vertically movably mounted in the mounting groove and its bottom is connected to the pressure sensor. A third screw is vertically mounted on the fine-tuning seat, and a connecting block fixed on one side of the vertical moving block is threaded onto the third screw. An adjustment part is provided at the upper end of the third screw.

[0010] Preferably, the adjusting part is a bolt adjusting head.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When the first screw is driven to rotate by the first motor, the lifting platform can be driven to slide up and down, thereby adjusting the overall height of the positioning component to adapt to the rapid installation of rollers of different sizes.

[0013] 2. When the second screw is rotated by rotating the handwheel, the two moving blocks on the positive and negative threads of the second screw can move away or move closer simultaneously. Then, the rotation and swing of the first and second connecting rods on both sides can drive the two transverse plates to move away or move closer simultaneously, thereby adjusting the horizontal distance between the corresponding rollers on both sides of the roller body to adapt to the support of rollers with different diameters.

[0014] 3. Since the axial lengths of different rollers are different, this application can adjust the support position of the rollers below the roller by sliding the sliding plate left and right on the transverse plate, thereby enabling this application to be used for support and positioning of rollers of different lengths.

[0015] 4. After the roller body support is placed on the roller of this application, the pressure sensor will detect the pressure from the upper roller seat. When the pressure of the two corresponding rollers in front and behind the roller body is unbalanced, the third screw can be rotated by rotating the adjustment part, and then the vertical moving block can be moved up and down in the fine adjustment seat through the connecting block, thereby adjusting the height of the upper roller until the pressure detected by the two pressure sensors in front and behind is consistent, proving that the height of the two rollers in front and behind is adjusted in place, thereby realizing the fine adjustment of the roller height and effectively improving the cladding quality.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0020] like Figure 1-3 As shown, this utility model proposes a positioning and calibration fixture for laser cladding of a jack, including a cladding platform 1, a clamping assembly 2, and a positioning assembly. The clamping assembly 2 is installed on the left side of the cladding platform 1, and the positioning assembly is installed on the right side of the cladding platform 1. The left end of the roller is fixed to the clamping assembly 2, and the middle part of the roller is supported on the positioning assembly. The clamping assembly 2 adopts existing technology. The positioning assembly includes a bracket 3, a lifting platform 4, and multiple sets of support wheels. The support wheels are installed on the lifting platform 4 along the length of the roller. The lifting platform 4 is slidably mounted on the bracket 3 and connected to a lifting drive assembly on the bracket 3. Specifically, a slide rail can be installed on the bracket 3, and the lifting platform 4 is slidably mounted on the slide rail. The lifting drive assembly includes a first screw 31 and a first motor 32. The first screw 31 is vertically mounted on the bracket 3, and its end is poweredly connected to the first motor 32. The lifting platform 4 is threaded onto the first screw 31.

[0021] When the first screw 31 is rotated by the first motor 32, the lifting platform 4 can be driven to slide up and down, thereby adjusting the overall height of the positioning assembly to accommodate the rapid installation of rollers of different sizes.

[0022] Two transverse plates 5 are movably mounted on the lifting plates on both sides of the roller body. These two transverse plates 5 are slidably mounted on the lifting platform 4 and driven synchronously to move away from or towards each other by a synchronization adjustment assembly 52. ​​Specifically, the synchronization adjustment assembly 52 includes a second screw 522 and two connecting rod assemblies. The second screw 522 is mounted parallel to the roller body on the lifting platform 4 between the two transverse plates 5, and a rotating handwheel 521 is mounted at the end of the second screw 522. A first sliding groove 41 is horizontally formed on the upper surface of the lifting platform 4 in the front-to-back direction, and the bottom of the transverse plates 5 is slidably mounted in the first sliding groove 41. The two connecting rod assemblies are symmetrically mounted on the positive and negative threads on both sides of the second screw 522. The connecting rod assemblies include a first connecting rod 524 and a second connecting rod 523. A moving block 525 is threaded onto the second screw 522. The two connecting rods are arranged in an "eight" shape on both sides of the second screw 522, with one end rotatably connected to the moving block 525 and the other end rotatably connected to the corresponding transverse plate 5.

[0023] When the handwheel 521 drives the second screw 522 to rotate, the two moving blocks 525 on the positive and negative threads of the second screw 522 can move away or move closer simultaneously. Then, through the rotation and swing of the first connecting rod 524 and the second connecting rod 523 on both sides, the two transverse plates 5 can move away or move closer simultaneously, thereby adjusting the horizontal distance between the corresponding rollers 6 on both sides of the roller body to adapt to the support of rollers with different diameters.

[0024] The sliding plate 51 is horizontally mounted on the corresponding transverse plate 5 in an adjustable manner. Specifically, the transverse plate 5 has a second sliding groove 50 horizontally opened on the left and right, the bottom of the sliding plate 51 is slidably locked in the second sliding groove 50, and a locking bolt 511 is vertically mounted on the sliding plate 51, with the end of the locking bolt 511 abutting against the transverse plate 5.

[0025] Since different rollers have different axial lengths, this application can adjust the support position of the roller 6 below the roller by sliding the sliding plate 51 left and right on the transverse plate 5, thereby enabling this application to adapt to the support and positioning of rollers of different lengths.

[0026] Each set of support wheels includes two rollers 6 symmetrically positioned on both sides below the roller body. The rollers 6 are mounted on wheel seats 61. The bottom of the wheel seats 61 is mounted on the actuating end of the corresponding fine-tuning component via a pressure sensor 8. The fine-tuning component is fixed to the sliding plate 51. Specifically, the fine-tuning component includes a fine-tuning seat 71 and a vertical moving block 72. The bottom of the fine-tuning seat 71 is fixedly mounted on the sliding plate 51. The vertical moving block 72 is vertically slidably mounted within the fine-tuning seat 71. A mounting groove is provided in the middle of the vertical moving block 72, and the pressure sensor 8 is installed at the bottom of the mounting groove. The wheel seat 61 is vertically slidably mounted in the mounting groove, and its bottom is connected to the pressure sensor 8. A third screw 74 is vertically mounted on one side of the mounting groove on the fine-tuning seat 71. A connecting block 73 fixed on one side of the vertical moving block 72 is threaded onto the third screw 74. An adjusting part 741 is provided at the upper end of the third screw 74. The adjusting part 741 can be a bolt adjusting head.

[0027] After the roller body is supported on the roller 6 of this application, the pressure sensor 8 will detect the pressure from the upper wheel seat 61. When the pressure of the two corresponding rollers 6 at the front and rear of the roller body is unbalanced, the third screw 74 can be rotated by the rotation adjustment part 741, and then the vertical moving block 72 can be moved up and down in the fine adjustment seat 71 through the connecting block 73, thereby adjusting the height of the upper roller 6 until the pressure detected by the two pressure sensors 8 at the front and rear are consistent, proving that the height of the two rollers 6 at the front and rear is adjusted in place, thereby realizing the fine adjustment of the height of the roller 6, and thus effectively improving the cladding quality.

[0028] When using this invention, first adjust the overall height of the lifting platform 4, the distance between the two transverse plates 5, and the position of each sliding plate 51 on the transverse plate 5 according to the diameter and length of the roller body. After the roller body is installed in place on the clamping assembly 2 and the support wheel group, determine whether the support of the corresponding front and rear rollers 6 is balanced according to the pressure detected by the pressure sensor 8. If it is not balanced, the height of the roller 6 can be finely adjusted by rotating the adjustment part 741 corresponding to the roller 6 and using the rotation of the third screw 74, thereby significantly improving the cladding quality.
