Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to a grinding machine for hydraulic valve blocks. Background Technology

[0002] A surface grinder is a metalworking machine that uses a rotating grinding wheel to grind workpieces to achieve the required flatness. Surface grinders are mainly used for surface treatment of metal parts, such as achieving surface flatness, precision, and smoothness, and can also handle workpiece dimensions. Furthermore, its machining accuracy is extremely high, reaching 0.000025 mm, therefore it is often used for precision machining.

[0003] When machining hydraulic valve blocks on a surface grinder, several aspects need to be considered to ensure machining quality and valve block performance. The operator needs to position and clamp the hydraulic valve block to prevent slippage during machining. During the machining process, the manufacturing environment must be kept clean, and debris must be removed promptly. This helps prevent surface damage caused by debris entering the hydraulic valve block or tool malfunctions during cutting. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 6 As shown, a grinding machine for hydraulic valve blocks includes a grinding machine body 1, on which a worktable 2 is provided. A hydraulic valve block clamping mechanism is fixedly connected to the worktable. By setting the hydraulic valve block clamping mechanism on the worktable, stable clamping of the hydraulic valve block is achieved, ensuring subsequent precise machining. The hydraulic valve block clamping mechanism includes a sliding frame 3, with a sliding groove 31 in the middle of the sliding frame. A bidirectional lead screw 4 is rotatably connected in the sliding groove. The end of the bidirectional lead screw passes through the sliding frame and is connected to a rotating wheel 5. A clamping plate 7 is installed on the bidirectional lead screw. The rotation of the rotating wheel allows the two clamping plates to move closer or further apart. The design of the bidirectional lead screw and the rotating wheel makes the adjustment of the clamping plates simple and quick, improving the adaptability and ease of operation of the equipment. A slag baffle 81 is installed in the sliding groove, directly above the bidirectional lead screw. By setting the slag baffle, the bidirectional lead screw is protected from interference by waste chips, improving the reliability and durability of the equipment.

[0015] In at least one embodiment, the bidirectional lead screw includes a clockwise threaded rod 41 and a counterclockwise threaded rod 42, which are connected together. The end of the clockwise threaded rod passes through the sliding frame and is connected to a rotating wheel. This structure allows the left and right clamping plates to move closer to or further away from each other simultaneously and at the same speed, ensuring the uniformity and stability of the clamping. The clamping plates include a left clamping plate 71 and a right clamping plate 72. A left threaded sleeve 61 is threaded onto the clockwise threaded rod, and a left clamping plate is fixedly connected to the left threaded sleeve. A right threaded sleeve 62 is threaded onto the counterclockwise threaded rod, and a right clamping plate is fixedly connected to the right threaded sleeve. The left and right threaded sleeves cooperate with the sliding groove. The independent movement design of the left and right clamping plates improves the flexibility and convenience of the clamping operation.

[0016] The solution is refined so that the rotation of the wheel can make the left and right threaded sleeves move along the sliding groove while the left and right clamping plates move closer or further apart.

[0017] In at least one embodiment, the bottom of the sliding frame is provided with a guide slider 32, and correspondingly, the worktable is provided with an insertion groove 21 that mates with the guide slider. The cooperation of the guide slider and the insertion groove allows the sliding frame to move smoothly along the worktable, ensuring the accuracy of the clamping position.

[0018] Furthermore, a locking knob is threaded onto the sliding groove, which allows the sliding frame to move along the worktable and be positioned at a certain point on the worktable. The locking knob design enables rapid positioning and locking of the sliding frame, improving the stability and safety of the equipment.

[0019] In at least one embodiment, both the left and right threaded sleeves are provided with an arc-shaped groove 82, and a slag-blocking plate is installed in the arc-shaped groove. The two ends of the slag-blocking plate are fixedly connected to the inner wall of the sliding groove. The cooperation between the arc-shaped groove and the slag-blocking plate can effectively prevent waste chips from falling onto the bidirectional lead screw, further protecting the normal operation of the bidirectional lead screw.

[0020] Furthermore, the arc-shaped groove is located directly above the bidirectional lead screw, and thus the slag baffle is also located directly above the bidirectional lead screw. This can be used to prevent the waste generated during the processing of the hydraulic valve block from falling onto the bidirectional lead screw and affecting the normal operation of the hydraulic valve block clamping mechanism.

[0021] The steps for using this grinding machine are as follows: I. Preparation Stage: Place the hydraulic valve block on the grinding machine in a suitable working area and ensure the equipment is stable. Inspect the grinding machine body, worktable, hydraulic valve block clamping mechanism, and other components for damage. Repair or replace any damaged parts promptly. Clean the worktable, ensuring it is free of debris and oil.

[0022] II. Clamping the hydraulic valve block: Place the hydraulic valve block to be processed on the worktable and adjust its position to align it with the clamping mechanism. Rotate the rotary wheel, driving the left and right clamping plates closer together via the double-acting screw, firmly clamping the hydraulic valve block between the clamping plates. Ensure the hydraulic valve block is stable and does not wobble. The position of the clamping mechanism can be adjusted using the sliding frame as needed to better accommodate hydraulic valve blocks of different sizes. During adjustment, loosen the locking knob, move the sliding frame to the appropriate position, and then tighten the locking knob to secure the sliding frame.

[0023] III. Machining the hydraulic valve block: Start the grinding machine body to allow the grinding wheel to begin rotating. Align the surface of the hydraulic valve block to be machined with the grinding wheel by adjusting the position and angle of the worktable. Slowly feed the worktable until the grinding wheel contacts the surface of the hydraulic valve block and begins grinding. Control the feed rate and grinding depth according to the machining requirements. During machining, continuously observe the surface quality of the hydraulic valve block and adjust the grinding parameters as needed. After machining is complete, stop feeding the worktable and shut down the grinding machine body.

[0024] IV. Cleaning and Maintenance: After processing, promptly clean up waste chips and debris on the worktable to maintain a clean working environment. Inspect the wear of the grinding wheel and clamping mechanism, and replace or repair them promptly if necessary. Perform routine maintenance and upkeep on the grinding machine body to ensure normal operation and extend the service life of the equipment.

[0025] Precautions: During operation, pay attention to safety precautions to avoid accidents. Personnel without professional training must not operate this equipment. If any abnormalities or malfunctions occur during use, stop the machine immediately, inspect and troubleshoot the problem before continuing use.
