Description

Technical Field

[0001] This utility model relates to the field of guide rail manufacturing technology, and in particular to an adaptive adjustable guide rail grinding machine fixture. Background Technology

[0002] A guideway grinding machine fixture is a device used to precisely position and fasten workpieces (mostly long and narrow parts such as machine tool guideways) during guideway grinding. Through reasonable positioning elements and clamping mechanisms, it ensures the stability of the workpiece position during grinding, reduces vibration and deformation, thereby ensuring the accuracy (such as straightness and parallelism) and surface quality of the guideway surface, and improving processing efficiency and consistency.

[0003] A search revealed that the document with publication number "CN217317562U" states that "this utility model relates to the field of grinding machine fixture technology, and in particular to a guide rail grinding machine fixture that facilitates adjustment of the processing position, including a base and a mounting table. A support seat is fixedly installed on one side of the mounting table, and a first motor is fixedly installed on one side of the support seat. A first lead screw is fixedly connected to the output end of the first motor, and a second lead screw is fixedly connected to the end of the first lead screw away from the first motor." The advantages of this utility model in use are: through the coordinated arrangement of the first motor, first lead screw, second lead screw, moving plate, moving connecting rod, clamping seat, movable block, knurled high-penetration screw, and clamping rod, the fixture structure can clamp and fix guide rails of different lengths and widths, expanding the applicability of the fixture structure, improving its practicality and structural flexibility, and simplifying the clamping operation of the guide rails, making it easy to clamp and fix guide rails of different lengths and widths.

[0004] However, in the machining industry, guide rail grinding is a common and important process. Traditional guide rail grinding machine fixtures usually adopt a fixed structural design, which cannot be adaptively adjusted according to guide rails of different widths. Some simple fixtures simply fix the guide rail by manually tightening bolts. This method is not only cumbersome to operate, but also makes it difficult to ensure that guide rails of different widths are in the optimal processing position. When processing guide rails of different specifications, it is necessary to frequently change or readjust the fixture, which seriously affects production efficiency and processing accuracy. In addition, some existing fixtures cannot effectively solve the problem of guide rail warping caused by uneven force during the grinding process, and cannot dynamically adjust according to changes in guide rail width in real time, making it difficult to guarantee grinding accuracy.

[0005] Therefore, we provide an adaptive adjustable guideway grinding machine fixture to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an adaptive adjustable guideway grinding machine fixture.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adaptive adjustable guideway grinding machine fixture includes a guideway grinding machine. An electric screw is installed on the inner side of the guideway grinding machine, and a guideway push plate is threaded onto the surface of the electric screw. A guideway body is installed on the upper left end of the guideway grinding machine, an upper grinding wheel is installed on the upper right end of the guideway grinding machine, a lower grinding wheel is installed on the right side of the guideway grinding machine, and a guideway grinding fixture fixing assembly is installed on the outer side of the guideway grinding machine. The guideway grinding fixture fixing assembly includes side frames installed at the front and rear ends of the guideway grinding machine. A fixing frame is installed on the right side of the side frames. A fixed hydraulic pump rod is installed on the upper side of each fixing frame. A pressure sensor is installed on the outer side of the fixed hydraulic pump rod. A fixed damper is connected to the outer side of the pressure sensor. A wheel frame is connected to the end of the fixed damper, and a side roller is installed on the inner side of the wheel frame.

[0009] As a further description of the above technical solution:

[0010] A driven shaft wheel is installed on the inner side of the side frame, and an adjusting clamp is connected to the right side of the driven shaft wheel. A clamp damper is installed on the rear side of the adjusting clamp. The adjusting clamp and the side frame form a rotating structure through the driven shaft wheel. The adjusting clamp adjusts the side position of the guide rail body through the clamp damper.

[0011] As a further description of the above technical solution:

[0012] The fixed hydraulic pump rod is welded to the fixed frame. The fixed hydraulic pump rod is arranged in two sets and is a proportional servo hydraulic valve.

[0013] As a further description of the above technical solution:

[0014] The pressure sensor and the fixed hydraulic pump rod are in one-to-one correspondence. The pressure sensor is electrically connected to an induction controller. The pressure sensor is a strain gauge pressure sensor. The fixed hydraulic pump rod and the pressure sensor are electrically connected in series through the induction controller.

[0015] As a further description of the above technical solution:

[0016] The fixed damper and the pressure sensor are welded together, and there is a one-to-one correspondence between the fixed damper and the pressure sensor.

[0017] As a further description of the above technical solution:

[0018] The side rollers are connected to the wheel frame by a shaft, and two sets of side rollers and wheel frames are arranged in groups. The surface of the side rollers is made of rubber.

[0020] The upper outer end of the lower grinding wheel is equipped with an upper hydraulic pump rod, the upper inner end of the upper hydraulic pump rod is equipped with an upper limiting damper, and the end of the upper limiting damper is equipped with an upper fixed roller.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model uses a guide rail grinding fixture fixing component. When needed, the operator moves the guide rail push plate via an electric screw, which in turn pushes the guide rail body to slide along the track direction of the guide rail grinding machine. During this process, the adjusting clamps on both sides clamp the guide rail body in the middle, while the width of the guide rail body itself pushes the adjusting clamps outward in the opposite direction. At this time, the adjusting clamps, constrained by the driven shaft wheel in the side frame, will push the clamp damping to adjust the extension and retraction, thereby limiting the guide rail body and ensuring that the guide rail body is located in the center position of the guide rail grinding machine as much as possible, providing convenience for subsequent fixing operations. After the guide rail body has been ground by the upper grinding wheel, the upper hydraulic pump rod, through proportional servo control, precisely adjusts the position of the upper fixing roller, thereby limiting and supporting the guide rail body from the top, preventing the lower grinding wheel from lifting up during the grinding of the lower surface of the guide rail body from the bottom, and ensuring the stability of the grinding position.

[0023] 2. This utility model uses a guide rail grinding fixture fixing component. As the guide rail body moves, the side rollers can smoothly pass through the guide rail body through their circular structure. The rubber material on the surface of the side rollers provides effective friction, helping to improve the conveying stability of the guide rail body. The fixed damping, through its own elasticity, buffers the guide rail body within a certain pressure range, effectively reducing vibration during the grinding process and providing a certain elastic support for the side rollers. It can automatically fine-tune within a certain range of extension and contraction. The pressure changes of the fixed damping are accurately captured by the pressure sensor and fed back to the fixed hydraulic pump rod in real time through the induction controller, so that it can quickly adjust the pressure output to adapt to guide rail bodies of different widths. This ensures that the guide rail body always maintains a balanced force during the grinding process and avoids grinding accuracy deviations caused by uneven pressure. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: an adaptive adjustable guideway grinding machine fixture, including a guideway grinding machine 1, an electric screw 2 disposed on the inner side of the guideway grinding machine 1, a guideway push plate 3 threadedly connected to the surface of the electric screw 2, a guideway body 4 mounted on the upper left end of the guideway grinding machine 1, an upper grinding wheel 5 mounted on the upper right end of the guideway grinding machine 1, a lower grinding wheel 6 disposed on the right side of the guideway grinding machine 1, and a guideway grinding fixture fixing assembly 7 disposed on the outer side of the guideway grinding machine 1. The grinding fixture fixing assembly 7 includes a side frame 701 installed at both ends of the guide rail grinding machine 1. A fixing frame 705 is provided on the right side of the side frame 701. A fixed hydraulic pump rod 706 is installed on the upper side of the fixing frame 705. A pressure sensor 707 is provided on the outer side of the fixed hydraulic pump rod 706. A fixed damper 709 is connected to the outer side of the pressure sensor 707. A wheel frame 710 is connected to the end of the fixed damper 709. A side roller 711 is installed on the inner side of the wheel frame 710.

[0033] Furthermore, a driven shaft wheel 702 is installed on the inner side of the side frame 701. An adjusting clamp 703 is connected to the right side of the driven shaft wheel 702. A clamp damper 704 is installed on the rear side of the adjusting clamp 703. The adjusting clamp 703 and the side frame 701 form a rotating structure through the driven shaft wheel 702. The adjusting clamp 703 adjusts the side position of the guide rail body 4 through the clamp damper 704. When needed, the operator drives the guide rail push plate 3 to move through the electric screw 2, and the guide rail push plate 3 pushes the guide rail body 4. The body 4 slides along the track direction of the guide rail grinding machine 1. During this process, the adjusting clamps 703 on both sides will clamp the guide rail body 4 in the middle, while the width of the guide rail body 4 itself will push the adjusting clamps 703 outward in the opposite direction. At this time, the adjusting clamps 703, constrained by the driven shaft wheel 702 in the side frame 701, will push the clamp damper 704 to extend and retract, thereby achieving the limit of the guide rail body 4 and ensuring that the guide rail body 4 is located in the center position of the guide rail grinding machine 1 as much as possible, which provides convenience for subsequent fixing operations.

[0034] Furthermore, the fixed hydraulic pump rod 706 is welded to the fixed frame 705. The fixed hydraulic pump rod 706 is arranged in two sets. The type of fixed hydraulic pump rod 706 is a proportional servo hydraulic valve. When the guide rail body 4 enters the middle of the side rollers 711 on both sides, the fixed hydraulic pump rod 706 adjusts the pressure through proportional servo control, thereby adapting to guide rail bodies 4 of different widths and ensuring its stability during the grinding process.

[0035] Furthermore, there is a one-to-one correspondence between the pressure sensor 707 and the fixed hydraulic pump rod 706. The pressure sensor 707 is electrically connected to the induction controller 708. The pressure sensor 707 is a strain gauge pressure sensor. The fixed hydraulic pump rod 706 and the pressure sensor 707 are electrically connected in series through the induction controller 708. When needed, the pressure change of the fixed damper 709 will be accurately captured by the pressure sensor 707 and fed back to the fixed hydraulic pump rod 706 in real time through the induction controller 708, so that it can quickly adjust the pressure output and ensure that the guide rail body 4 always maintains a balanced force during the grinding process, avoiding grinding accuracy deviation caused by uneven pressure.

[0036] Furthermore, the fixed damper 709 and the pressure sensor 707 are welded together, and there is a one-to-one correspondence between the fixed damper 709 and the pressure sensor 707. When needed, the fixed damper 709 uses its own elasticity to buffer the guide rail body 4 within a certain pressure range, effectively reducing the vibration during the grinding process, and providing a certain elastic support for the side roller 711, and automatically fine-tuning within a certain range of extension and contraction.

[0037] Furthermore, the side roller 711 is connected to the wheel frame 710 by a shaft. The side roller 711 and the wheel frame 710 are arranged in two sets. The surface of the side roller 711 is made of rubber. When it is needed, as the guide rail body 4 moves, the side roller 711 can allow the guide rail body 4 to pass smoothly through its own circular structure. The rubber material on the surface of the side roller 711 can provide effective friction and help improve the conveying stability of the guide rail body 4.

[0038] Furthermore, an upper hydraulic pump rod 712 is installed on the upper outer end of the lower grinding wheel 6, an upper limit damper 713 is installed on the upper inner end of the upper hydraulic pump rod 712, and an upper fixed roller 714 is installed at the end of the upper limit damper 713. After the guide rail body 4 is ground by the upper surface of the upper grinding wheel 5, the upper hydraulic pump rod 712 is precisely adjusted by proportional servo control to adjust the position of the upper fixed roller 714, thereby providing limit support for the guide rail body 4 from the top, avoiding the problem of the lower grinding wheel 6 lifting its head during the grinding process of the lower surface of the guide rail body 4 from the bottom, and ensuring the stability of the grinding position.

[0039] Working principle: When needed, first install the guide rail grinding machine 1 in the required position, then place the guide rail body 4 on the guide rail grinding machine 1. As the electric screw 2 starts, it drives the guide rail push plate 3 to move forward. At this time, the end of the guide rail body 4 will be engaged between the two sets of adjusting clamps 703. After being subjected to force, the adjusting clamp 703 is constrained by the driven shaft wheel 702 in the side frame 701, so only the end of the adjusting clamp 703 rotates. At this time, the clamp damping 704 outside the adjusting clamp 703 squeezes the adjusting clamp 703, thereby keeping the guide rail body 4 stable in the horizontal direction and in the middle position of the guide rail grinding machine 1, until it enters the middle of the side rollers 711 on the fixed frame 705. At this time, the side rollers 711 on both sides will squeeze the guide rail body 4. After being subjected to force, the side rollers 711 will squeeze the fixed damping 709 through the wheel frame 710. The fixed damping 709 The pressure is transmitted to the pressure sensor 707. When the pressure is greater than or less than the preset value, the sensor controller 708 controls the fixed hydraulic pump rod 706 to extend and retract to ensure that the pressure of the guide rail body 4 between the side rollers 711 is balanced. This achieves accurate positioning and stable operation of the guide rail body 4 during the grinding process, continuously feeding the guide rail body 4 into the upper grinding wheel 5 for grinding. After the upper grinding is completed, the moving guide rail body 4 will be fed above the lower grinding wheel 6. At this time, the upper hydraulic pump rod 712 will be adjusted according to the height of the guide rail body 4 to ensure that the upper fixed roller 714 will exert downward pressure on the guide rail body 4. The upper limit damper 713 will buffer and finely adjust the pressure to ensure that the guide rail body 4 will not tilt during the grinding process of the lower grinding wheel 6. This completes the use of an adaptive adjustment guide rail grinding machine fixture.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
