Description
Technical Field
[0001] This utility model relates to the field of roll grinding machine technology, specifically to a parallel grinding wheel transfer carriage for roll grinding machines. Background Technology
[0002] The main function of parallel grinding wheels in roll grinding machines is to grind and polish the surface of workpieces, improving their flatness and precision. The parallel grinding wheel smooths out the uneven parts of the workpiece surface through friction with the workpiece surface, thereby achieving the required precision and smoothness.
[0003] The parallel grinding wheels used in existing roll grinding machines have a large diameter and heavy weight, which makes it inconvenient to transfer the parallel grinding wheels when changing them. When changing parallel grinding wheels, the parallel grinding wheels need to be placed vertically for lifting. However, during the process of transferring the parallel grinding wheels from the placement area to the replacement area, the outer circle of the grinding wheel is usually used for rolling. It is difficult to maintain the balance during the rolling of the parallel grinding wheel, which can easily cause it to tip over, resulting in damage to the parallel grinding wheel or injury to personnel, posing a safety hazard. Summary of the Invention
[0004] This invention addresses the problem of inconvenient parallel grinding wheel transfer during replacement in existing roll grinding machines by providing a parallel grinding wheel transfer cart for roll grinding machines. This cart facilitates the transfer of parallel grinding wheels and allows them to be transferred vertically from the placement area to the replacement area. This facilitates the hoisting of parallel grinding wheels during replacement in roll grinding machines and prevents them from tipping over during transfer.
[0005] To achieve the above objectives, the technical solution of this utility model is: a parallel grinding wheel transfer carriage for a roll grinding machine, comprising a transfer frame and a transfer wheel disposed at the bottom of the transfer frame. A bridge plate is disposed at the top front end of the transfer frame. A grinding wheel support seat is disposed on the transfer frame at an angle downwards away from the bridge plate. A groove is formed on the top of the grinding wheel support seat, corresponding to the bridge plate. A rear stop and a front stop are disposed inside the groove. The grinding wheel support seat supports the parallel grinding wheel. The bridge plate can be connected to a grinding wheel holder for storing parallel grinding wheels, facilitating the rolling of the parallel grinding wheel into the groove. The groove allows the parallel grinding wheel to be transferred vertically, while preventing it from tipping over. The rear stop and front stop limit the movement of the parallel grinding wheel within the groove.
[0006] A horizontal support rod is fixedly installed at the bottom of the transfer frame, and symmetrically arranged at the top of the horizontal support rod are limiting stops for restricting the position of the grinding wheel support. The limiting stops are located inside the transfer frame and connected to it. The limiting stops can restrict the position of the grinding wheel support to prevent the grinding wheel support from sliding on the transfer frame.
[0007] Furthermore, transfer wheels are provided at the bottom corners of the transfer frame, and a handrail is fixedly installed at the top rear end of the transfer frame. The top of the transfer frame also has symmetrically arranged diagonal braces connected to the handrail. The transfer wheels facilitate the movement of the transfer cart to transfer the parallel grinding wheel, and the handrail allows workers to push and pull the transfer cart.
[0008] Furthermore, the front end of the groove has an "eight" shaped structure, and one end of the bridge plate is located inside the groove, while the other end extends to the outside of the groove. The purpose of this is to allow the parallel grinding wheel to roll into the groove through the bridge plate.
[0009] Furthermore, the rear stop block has a rearward tilting portion at one end near the front stop block, and the front stop block has a frontward tilting portion at one end near the rear stop block. Both the rear stop block and the front stop block have lifting lugs at their tops. The rearward tilting portion of the rear stop block is used to limit the parallel grinding wheel, and the frontward tilting portion of the front stop block is used to limit the parallel grinding wheel. The lifting lugs are used to remove the front stop block and the rear stop block from the groove.
[0010] Furthermore, limit blocks are symmetrically arranged on both sides of the rear stop block, and multiple limit grooves matching the limit blocks are arranged at intervals on both sides of the groove. Through the cooperation of the limit blocks and the limit grooves, the rear stop block is prevented from sliding downward in the groove due to the weight of the parallel grinding wheel.
[0011] Furthermore, a concave groove is provided at the bottom of the front end of the grinding wheel support, and the front end of the grinding wheel support is engaged on the transfer frame through the concave groove; symmetrical limit stop grooves are provided on both sides of the middle part of the grinding wheel support, and the grinding wheel support is engaged on the limit stop bar through the limit stop groove. Through the cooperation of the concave groove and the transfer frame, and the limit stop groove and the limit stop block, the purpose of installing the grinding wheel support on the transfer frame is achieved.
[0012] Furthermore, a central support rod is provided at the position corresponding to the groove below the grinding wheel support base. Longitudinal support rods are symmetrically arranged on both sides of the central support rod. Both the central support rod and the longitudinal support rods are inclined downward and connected to the transverse support rods. Both ends of the central support rod and the longitudinal support rods are connected to the transfer frame. The central support rod and the longitudinal support rods provide support for the grinding wheel support base.
[0013] The beneficial effects of this utility model through the above technical solution are as follows:
[0014] This utility model has a reasonable structure and good performance. It can transfer parallel grinding wheels, replacing the method of rolling and shifting parallel grinding wheels. It can transfer parallel grinding wheels vertically from the placement area to the replacement area, so as to facilitate the hoisting of parallel grinding wheels when changing parallel grinding wheels on the roll grinding machine. It can also avoid the phenomenon of parallel grinding wheels tipping over during the transfer process, thereby avoiding damage to parallel grinding wheels or injury to personnel.
[0015] This utility model provides support for parallel grinding wheels. The bridge plate can be connected to the grinding wheel rack that stores the parallel grinding wheels, making it easy to roll the parallel grinding wheels into the groove. The inner sides of the groove block the parallel grinding wheels located in the groove, which can achieve the effect of transferring the parallel grinding wheels vertically from the placement area to the changing area, and at the same time, it can also prevent the parallel grinding wheels from tipping over during the transfer process.
[0016] The grinding wheel support of this utility model is inclined downwards, so that the groove on the grinding wheel support is also in an inclined state. The purpose is to prevent the parallel grinding wheel located in the groove from rolling out of the groove during transportation. At the same time, the rear stop and the front stop limit the parallel grinding wheel to prevent it from moving in the groove. The limiting blocks on both sides of the rear stop cooperate with the limiting groove to prevent the rear stop from sliding downwards in the groove under the weight of the parallel grinding wheel, thus ensuring that the rear stop limits the parallel grinding wheel.

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0025] like Figures 1-6 As shown, a parallel grinding wheel transfer carriage for a roll grinding machine includes a transfer frame 1 and a transfer wheel 2 disposed at the bottom of the transfer frame 1. A bridge plate 11 is provided at the top front end of the transfer frame 1. A grinding wheel support seat 9 is provided on the transfer frame 1 at an angle downward away from the bridge plate 11. A groove 10 is formed on the top of the grinding wheel support seat 9, and the groove 10 corresponds to the bridge plate 11. A rear stop block 12 and a front stop block 17 are provided inside the groove 10. In this embodiment, the bridge plate 11 is welded and fixed at the middle position of the top of the transfer frame 1. The bridge plate 11 is used to connect with the grinding wheel frame that stores the parallel grinding wheel. The front end of the bridge plate 11 has a trapezoidal structure to facilitate the connection between the bridge plate 11 and the grinding wheel frame, so that the parallel grinding wheel can roll from the grinding wheel frame through the bridge plate 11 into the groove 10. The grinding wheel support 9 is made of wood and is installed on the transfer frame 1 at a downward inclination, so that the groove 10 is also in an inclined state. The purpose is to prevent the parallel grinding wheel located in the groove 10 from rolling out of the groove 10 during the transfer of the parallel grinding wheel. The rear stop 12 and the front stop 17 can be removed from the groove 10. When the parallel grinding wheel is rolled from the grinding wheel frame into the groove 10, the front stop 17 is removed from the groove 10 first.
[0026] A transverse support rod 5 is fixedly installed at the bottom of the transfer frame 1. A limiting stop rod 8, used to restrict the position of the grinding wheel support seat 9, is symmetrically installed at the top of the transverse support rod 5. The limiting stop rod 8 is located inside the transfer frame 1 and connected to it. In this embodiment, the transverse support rod 5 is welded and fixed at the middle position of the bottom of the transfer frame 1. The limiting stop rod 8 is welded and fixed to both the transverse support rod 5 and the transfer frame 1. The cross-sections of the limiting stop rod 8 and the transverse support rod 5 are square. The limiting stop rod 8 restricts the position of the grinding wheel support seat 9 to prevent it from sliding on the transfer frame 1.
[0027] The transfer frame 1 is equipped with transfer wheels 2 at its bottom corners, and a handrail 3 is fixedly installed at the top rear end of the transfer frame 1. The top of the transfer frame 1 is also symmetrically equipped with diagonal braces 4 connected to the handrail 3. In this embodiment, there are four transfer wheels 2, with the two at the rear end of the transfer frame 1 being omnidirectional wheels and the two at the front end being directional wheels. The transfer wheels 2 facilitate the movement of the transfer vehicle. The handrail 3 is welded and fixed to the top of the transfer frame 1, facilitating the pushing and pulling of the transfer vehicle by the staff. The diagonal braces 4 are inclined, with both ends welded and fixed to the transfer frame 1 and the handrail 3, respectively.
[0028] The front end of the groove 10 has an "eight" shape, and one end of the bridge plate 11 is located inside the groove 10, while the other end extends to the outside of the groove 10. In this embodiment, the front end of the groove 10 has an "eight" shape, which is intended to facilitate the parallel grinding wheel to roll from the grinding wheel holder through the bridge plate 11 into the groove 10. One end of the bridge plate 11 extends to the outside of the groove 10 to facilitate the connection between the bridge plate 11 and the grinding wheel holder.
[0029] The rear stop 12 has a rearward tilting portion 13 at one end near the front stop 17, and the front stop 17 has a frontward tilting portion 18 at one end near the rear stop 12. Both the rear stop 12 and the front stop 17 have lifting lugs 15 at their tops. In this embodiment, the rearward tilting portion 13 of the rear stop 12 is used to limit the parallel grinding wheel, and the frontward tilting portion 18 of the front stop 17 is used to limit the parallel grinding wheel. The lifting lugs 15 are used to remove the front stop 17 and the rear stop 12 from the groove 10. Both the front stop 17 and the rear stop 12 are made of wood.
[0030] The rear stop 12 is symmetrically provided with limiting blocks 14 on both sides, and the groove 10 is provided with multiple limiting grooves 16 that match the limiting blocks 14 on both sides at intervals. In this embodiment, the cooperation between the limiting blocks 14 and the limiting grooves 16 prevents the rear stop 12 from sliding downward in the groove 10 due to the weight of the parallel grinding wheel. There are eight limiting grooves 16 on both sides of the groove 10. The position of the rear stop 12 can be adjusted by adjusting the insertion of the limiting blocks 14 into the limiting grooves 16 at different positions, thereby adjusting the position of the parallel grinding wheel in the groove 10.
[0031] The front end of the grinding wheel support 9 has a concave groove at its bottom, and the front end of the grinding wheel support 9 is engaged with the transfer frame 1 through the concave groove. The grinding wheel support 9 has symmetrical limit grooves on both sides of its middle portion, and the grinding wheel support 9 is engaged with the limit stop 8 through the limit stop grooves. In this embodiment, the grinding wheel support 9 is installed onto the transfer frame 1 by the cooperation of the concave groove with the transfer frame 1 and the limit stop grooves with the limit stop 8.
[0032] A central support rod 6 is provided below the grinding wheel support base 9 at the position corresponding to the groove 10. Longitudinal support rods 7 are symmetrically arranged on both sides of the central support rod 6. Both the central support rod 6 and the longitudinal support rods 7 are inclined downwards and connected to the transverse support rod 5. Both ends of the central support rod 6 and the longitudinal support rods 7 are connected to the transfer frame 1. In this embodiment, both the central support rod 6 and the longitudinal support rods 7 provide support for the grinding wheel support base 9. The central support rod 6, at the position corresponding to the groove 10, supports the grinding wheel support base 9, thus preventing damage to the grinding wheel support base 9 due to excessive weight of the parallel grinding wheel.
[0033] The working principle of this utility model is as follows: When the parallel grinding wheel of the roll grinding machine needs to be replaced and the parallel grinding wheel needs to be transferred from the placement area to the changing area, the operator can hold the handle 3 and push the transfer cart to the grinding wheel frame where the parallel grinding wheel is stored. Then, the front stop 17 is taken out of the groove 10 through the lifting lug 15. Then, the bridge plate 11 is aligned with the grinding wheel frame and the parallel grinding wheel. When the bridge plate 11 moves into the gap on the grinding wheel frame and is located at the top of the grinding wheel frame, the parallel grinding wheel can be rolled. The parallel grinding wheel is rolled through the bridge plate 11 into the groove 10. Then, the parallel grinding wheel is rolled downward in the groove 10 until it contacts the rear inclined part 13 of the rear stop 12. Finally, the front stop 17 is put into the groove 10, and the front inclined part 18 on the front stop 17 corresponds to the rear inclined part 13 of the rear stop 12. The parallel grinding wheel is placed in the groove 10. The two sides of the groove 10 limit the parallel grinding wheel to keep it in a vertical position. Then, the workers can push and pull the transfer cart through the handrail 3 to transfer the parallel grinding wheel from the placement area to the changing area in a vertical position. After the transfer cart moves to the changing area, the overhead crane can be used to lift the parallel grinding wheel.
