Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a linkage self-centering clamp for a cleaning machine. Background Art

[0002] In the field of modern industrial manufacturing, granulation molds, especially flat molds, are a key molding equipment widely used in many industries such as plastics, chemicals, food, and medicine to efficiently and accurately process raw materials into particles of specific shapes and sizes. However, during the manufacturing process of the mold, burrs will inevitably be generated on the mold surface due to process operations such as cutting and grinding. In addition, during use, dirt may accumulate inside the mold due to factors such as material residue and wear. These burrs and dirt not only affect the precision of the mold and reduce product quality, but also aggravate the wear of the mold, shorten its service life, and even cause safety production problems.

[0003] In response to the above problems, the industry usually uses professional deburring and cleaning machines to deal with them. This type of equipment effectively removes burrs and dirt on the surface and inside of the mold by physical or chemical means to ensure the cleanliness and processing quality of the mold. However, for granulation molds with a wide variety of models and sizes, especially flat molds, the clamping process often becomes a major challenge. Traditional clamping methods usually rely on manual positioning and fixing, which is not only inefficient, but also difficult to ensure clamping accuracy, and easily causes mold positioning deviation, affecting deburring and cleaning effects. In addition, frequent manual operations may also cause mold damage, increasing additional maintenance costs.

[0004] In view of this, the market urgently needs a special fixture that can adapt to various models and sizes of granulation molds, especially flat molds, to achieve fast and accurate clamping, and can effectively cooperate with the deburring and cleaning machine. Such a fixture should have good versatility and stability to overcome the defects of mold clamping difficulty, low efficiency, and poor precision in the existing technology, improve the overall efficiency and quality of the entire deburring and cleaning process, and reduce labor costs and mold losses. Utility Model Content

[0005] The purpose of the utility model is to provide a fast-linked self-centering clamp specially used for a granulation mold (flat mold) to solve the problem that the mold clamping process in the prior art usually relies on manual positioning and fixing, which is not only inefficient, but also difficult to ensure the clamping accuracy, easily causing mold positioning deviation, and affecting the deburring and cleaning effects.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A linkage self-centering fixture for a cleaning machine, comprising: a fixed plate and a rotating plate movably connected to the top of the fixed plate, a plurality of locking grooves are mirror-imaged near the edges of the fixed plate and the rotating plate, and a locking hand wheel for fixing the fixed plate and the rotating plate is movably connected in each locking groove;

[0008] A plurality of arc-shaped radiation grooves are mirror-imaged on the fixed plate and the rotating plate, and a columnar clamping claw for clamping a workpiece is movably arranged in each radiation groove, and the curvature of the locking groove is adapted to the curvature of the radiation groove.

[0009] Through the movable connection between the fixed plate and the rotating plate, and the locking handwheel, the entire fixture can be flexibly adjusted according to workpieces of different sizes and shapes, achieving self-centering positioning, ensuring that the workpiece remains stable and centered during the cleaning process, and improving the accuracy and consistency of the cleaning operation. The curved radiation grooves and the movable cylindrical clamping jaws can not only meet the clamping needs of workpieces of various shapes, but also evenly distribute the clamping force, reducing the risk of deformation caused by excessive local force on the workpiece.

[0010] Furthermore, the outside of the cylindrical clamping jaw is wrapped with a non-slip rubber sleeve.

[0011] Furthermore, a silicone support strip is provided between the cylindrical clamping jaws on the turntable to prevent the clamped workpiece from sliding.

[0012] Furthermore, the shape of the silicone support strip is a convex structure.

[0013] The convex-shaped silicone support strips on the turntable provide good support when clamping the workpiece, preventing the workpiece from sliding or swinging between adjacent jaws, and ensuring that the workpiece is firmly fixed on the fixture in all directions.

[0014] Furthermore, a plurality of operating handles are provided near the outer edge of the turntable for facilitating the rotation of the turntable.

[0015] Multiple operating handles make it easy for workers to rotate the turntable from different angles, making it easier and quicker to load and unload workpieces, improving work efficiency.

[0016] Furthermore, the outside of the operating handle is wrapped with a non-slip rubber sleeve.

[0017] The cylindrical clamping jaws and the anti-slip rubber sleeve on the operating handle increase the friction, effectively preventing the workpiece from slipping due to unstable force or slippery conditions during the clamping process. It also improves the operator's feel and safety when rotating the turntable.

[0018] Furthermore, the locking hand wheel has a curved pentagonal structure.

[0019] Furthermore, a core shaft for connecting the clamp to the cleaning machine is fixed to the step at the bottom of the fixed plate by screws.

[0020] Through the connection method of the core shaft and screw fixing, the clamp can be easily and quickly installed on the cleaning machine, achieving good adaptation and linkage with the cleaning equipment, and meeting the needs of the automated cleaning production line.

[0021] The utility model has the following beneficial effects:

[0022] The utility model flexibly connects the fixed plate and the rotating plate, and cooperates with the locking hand wheel, so that the entire clamp can be flexibly adjusted according to workpieces of different sizes and shapes, realizes self-centering positioning, ensures that the workpiece remains stable and centered during the cleaning process, and improves the accuracy and consistency of the cleaning operation. The multiple locking grooves and locking hand wheels on the fixed plate and the rotating plate can ensure that the clamp is firmly locked after clamping the workpiece, avoiding displacement or loosening of the workpiece under the impact of high-pressure water flow during the cleaning process, and enhancing the safety and stability of the cleaning process.

[0027] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] Please refer to Figure 1-2 The present embodiment provides a linkage self-centering fixture for a cleaning machine. The fixture has an ingenious design, a compact structure, and a high-efficiency and stable workpiece fixing capability. It is suitable for accurately positioning and firmly clamping various workpieces during the operation of the cleaning machine.

[0029] The fixture mainly includes a fixed plate 1 (hereinafter referred to as the main fixed plate) and a rotating plate 2 (hereinafter referred to as the auxiliary rotating plate) movably connected to the top thereof. The main fixed plate and the auxiliary rotating plate are symmetrically provided with multiple sets of locking grooves 6 near their respective edges, and each set of locking grooves 6 is equipped with a locking handwheel 3 that can flexibly adjust and lock the relative position of the two plates. This design allows the user to conveniently adjust the distance between the main fixed plate and the auxiliary rotating plate according to the size of the workpiece to be cleaned and the cleaning requirements, ensuring that the workpiece is in the best cleaning position when clamped.

[0030] Please refer to Figure 1-2 , there are multiple curved radiation grooves 4 symmetrically distributed on the main fixed plate and the auxiliary rotating plate, and cylindrical clamps 5 are movably embedded in these radiation grooves 4. The cylindrical clamps 5 can move radially in the radiation grooves 4 to adapt to workpieces of different diameters and shapes to achieve clamping of the workpieces. In order to enhance the friction during the clamping process and prevent the workpiece from slipping, the outside of the cylindrical clamps 5 are covered with wear-resistant rubber sleeves with good anti-slip properties. Silicone support strips 7 are specially added between the cylindrical clamps 5 on the auxiliary rotating plate. The silicone support strips 7 are convex-shaped structures, and their design is to increase the friction between the workpiece clamped between adjacent clamps, effectively prevent the clamped workpiece from sliding laterally due to water flow impact or other vibration factors during the cleaning process, and ensure that the workpiece maintains a stable posture during the entire cleaning cycle. In order to prevent the cylindrical clamps 5 from being stuck during the relative movement of the fixed plate 1 and the rotating plate 2, the curvature of the locking groove 6 and the curvature of the radiation groove 4 need to be adapted to each other.

[0031] In order to facilitate the operator to manually rotate the auxiliary turntable to adjust the position of the clamp relative to the spray system of the cleaning machine or load and unload the workpiece, a plurality of operating handles 8 are provided on the outer edge of the auxiliary turntable. These handles are also covered with non-slip rubber sleeves, which not only improves the grip comfort, but also ensures the safety and controllability when operating with wet hands. It is worth mentioning that the locking handwheel 3 adopts a curved pentagonal structure design. This innovative form not only provides a good hand grip, but also avoids the risk of the clamp loosening due to accidental rotation of the traditional circular handwheel, and enhances the overall stability of the clamp.

[0032] In addition, the step at the bottom of the main plate is firmly fixed with a mandrel 9 by a high-strength screw. The mandrel serves as a connecting component between the fixture and the external cleaning equipment, ensuring that the fixture can be accurately installed and stably rotated on the workbench of the cleaning machine, realizing linkage operation with the cleaning machine.

[0033] The working principle of this embodiment is:

[0034] S1. Place the workpiece flat on the silicone support strip 7;

[0035] S2, grasp the operating handle 8 and rotate the turntable 2 clockwise, and the cylindrical claws 5 are linked to clamp the workpiece;

[0036] S3, rotating the locking hand wheel 3 to lock the turntable 2, and performing the cleaning operation;

[0037] S4, release the locking hand wheel 3 to release the turntable 2;

[0038] S5. Grasp the operating handle 8 and rotate the turntable 2 counterclockwise, release the cylindrical claw 5, and remove the workpiece.

[0039] To summarize, the linked self-centering clamp for the cleaning machine provided in this embodiment achieves efficient clamping, precise positioning and stable fixation of the workpiece during the cleaning process through the adjustable docking of the main fixed plate and the auxiliary turntable, radial movement of the cylindrical jaws, anti-slip positioning of the silicone support strip, convenient control of the operating handle and innovative design of the curved pentagonal locking handwheel, which significantly improves the working efficiency and cleaning quality of the cleaning machine and is suitable for automated cleaning of a variety of workpieces.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
