Technical Field

[0001] This invention relates to the fields of machining and surface treatment technology, and in particular to a planar polishing fixture suitable for efficient clamping and surface polishing of rectangular and other planar workpieces. Background Technology

[0002] When polishing or grinding various planar workpieces (such as rectangular, square, or other planar shapes), specialized fixtures are typically used to fix and position the workpieces to facilitate efficient and uniform surface treatment with the polishing machine. However, existing fixtures often suffer from problems such as complex structure, cumbersome operation, insufficient positioning accuracy, easy workpiece damage, and poor versatility, leading to decreased production efficiency, increased workpiece scrap rates, and higher rework costs. Therefore, there is an urgent need for a planar polishing fixture with a simple structure, accurate positioning, good versatility, and effective protection of the workpiece during clamping to meet the modern industrial demands for mass production, high precision, and high efficiency in surface treatment. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing planar polishing fixtures in terms of structure, operation, positioning, and workpiece protection, and to provide a planar polishing jig. This jig consists of a heightening block, a positioning block, a mechanical quick clamp, a pressure block, urethane adhesive, a slider, and a guide rail. The positioning block has at least one stop edge for reference positioning of the side of the product to be polished; the mechanical quick clamp is connected to the pressure block and, with the cooperation of the slider and guide rail, causes the pressure block to reciprocate, thereby achieving rapid clamping or releasing of the product to be polished; urethane adhesive is attached to the side of the pressure block facing the product to be polished, reducing surface scratches and pressure marks during clamping; the heightening block is used to fix the invention on the polishing machine table and adjust the overall height.

[0004] Preferably, the positioning block is detachably mounted on the heightening block, and can be adapted to products of different sizes and shapes by replacing positioning blocks of different specifications or sizes.

[0005] Preferably, the height of the retaining edge matches or exceeds the thickness of the product to be polished, thereby preventing the product from shaking or shifting position during the polishing process.

[0006] Preferably, the mechanical quick clamp includes a clamping arm and a linkage mechanism. The clamping arm is hinged to the pressure block via a pivot, and the linkage mechanism is linked to the slider to realize the rapid opening and closing of the clamping arm, thereby quickly clamping or releasing the product to be polished.

[0007] Preferably, the urethane adhesive is fixedly or detachably installed on the bottom of the pressure block, and the thickness of the urethane adhesive can be adjusted according to the material of the product to be polished and the clamping requirements to enhance the protection of the product to be polished.

[0008] Preferably, the slider slides on the guide rail and is connected to the pressure block by screws or other fasteners to allow for fine-tuning according to the size and position of the product to be polished and to maintain precise positioning.

[0009] Preferably, the heightening block is provided with several mounting holes for installation in conjunction with the fixing components of the polishing machine table, so as to ensure that the flat polishing fixture is firmly installed on the polishing machine table and its height is adjustable.

[0010] Preferably, a reserved space is provided between the positioning block and the pressure block so that the product to be polished can be loaded and unloaded after the mechanical quick clamp is released, so as to realize quick workpiece change or automated production.

[0011] Preferably, a number of positioning pins or positioning grooves are added to the positioning block or the pressure block for error-proof positioning or to further achieve precise positioning of workpieces with special shapes.

[0012] The beneficial effects of this invention are as follows:

[0013] Firstly, using the stop edge on the positioning block as the reference positioning surface of the workpiece can effectively improve positioning accuracy and reduce the risk of workpiece displacement during polishing. Secondly, the mechanical quick clamp drives the pressure block to quickly clamp or release, greatly reducing the difficulty of operation and the loading and unloading time, thus improving production efficiency. Thirdly, the cushioning effect of the urethane rubber protects the workpiece surface to a certain extent, preventing damage caused by excessive clamping force or improper positioning. Fourthly, the heightening block design allows the fixture to be flexibly matched with polishing machines of different heights or types, and can be easily modified to adapt to flat workpieces of different sizes, thicknesses, and shapes. Fifthly, the overall structure is simple, inexpensive, and easy to maintain, making it suitable for widespread use in multi-variety or high-volume production environments.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To make the technical solution and outstanding advantages of the present invention clearer, its embodiments are described in detail below with reference to the accompanying drawings. It should be understood that those skilled in the art can make equivalent or modified improvements to its structure, shape, and component combination without departing from the concept of the present invention, and these improvements should be considered to fall within the protection scope of the present invention.

[0023] like Figures 1 to 4 As shown, the planar polishing fixture of the present invention includes a heightening block 1, a positioning block 2, a mechanical quick clamp 3, a pressure block 4, urethane adhesive 5, a slider 7, and a guide rail 8. The positioning block 2 is provided with at least one retaining edge 21 for reference positioning of the side of the product 6 to be polished. The mechanical quick clamp 3 is connected to the pressure block 4 and works with the slider 7 and the guide rail 8 to realize the reciprocating movement of the pressure block 4. The urethane adhesive 5 is attached to the side of the pressure block 4 facing the product 6 to be polished to reduce the impact and squeezing of the product 6 to be polished during clamping. The heightening block 1 is connected to the polishing machine table and is used for height adjustment so that the product 6 to be polished is in a suitable polishing position. When the mechanical quick clamp 3 drives the pressure block 4 to slide, the product 6 to be polished is pressed on the positioning block 2 and the retaining edge 21, thereby realizing fast and accurate polishing positioning and clamping of planar workpieces of different shapes and sizes.

[0024] The positioning block 2 is detachably mounted on the raising block 1, and can be adapted to polishing products 6 of different sizes and shapes by replacing the positioning block 2 with different specifications or sizes.

[0025] The height of the retaining edge 21 is matched with or greater than the thickness of the product 6 to be polished, thereby preventing the product 6 to be polished from shaking or shifting position during the polishing process.

[0026] The mechanical quick clamp 3 includes a clamping arm and a linkage mechanism. The clamping arm is hinged to the pressure block 4 via a pivot, and the linkage mechanism is linked with the slider 7 to realize the rapid opening and closing of the clamping arm, thereby quickly clamping or releasing the product 6 to be polished.

[0027] The bottom of the pressure block 4 is fixedly or detachably fitted with urethane 5, and the thickness of the urethane 5 can be adjusted according to the material of the product 6 to be polished and the clamping requirements to enhance the protection of the product 6 to be polished.

[0028] The slider 7 slides on the guide rail 8 and is connected to the pressure block 4 by screws or other fasteners so as to fine-tune the position according to the size of the product 6 to be polished and maintain precise positioning.

[0029] The heightening block 1 is provided with several mounting holes for installation with the fixed parts of the polishing machine table, so as to ensure that the flat polishing fixture is firmly installed on the polishing machine table and its height is adjustable.

[0030] A reserved space is provided between the positioning block 2 and the pressure block 4 so that after the mechanical quick clamp 3 is released, the product to be polished 6 can be loaded and unloaded, so as to realize quick workpiece change or automated production.

[0031] Several positioning pins or positioning grooves are added to the positioning block 2 or the pressure block 4 to prevent mistaken positioning or to further achieve precise positioning of workpieces with special shapes.

[0032] Before use, the lifting block 1 can be fixed to the polishing machine table with screws or other fasteners, and the height or installation position of the lifting block 1 can be adjusted appropriately according to actual production needs. The positioning block 2 is fixed on the lifting block 1. The positioning block 2 has at least one retaining edge 21, and its height can be equal to or slightly higher than the thickness of the product 6 to be polished, which is used to provide a reference positioning for the side of the product 6 to be polished. If the specifications or shape of the product 6 to be polished changes, the positioning block 2 can be replaced or finely adjusted to adapt to the size and shape of different products.

[0033] The mechanical quick clamp 3 is connected to the pressure block 4 via clamping arms and connecting rods, and works with the slider 7 and guide rail 8 to reciprocate the pressure block 4 along the horizontal plane. When the mechanical quick clamp 3 is operated to the clamping position, the pressure block 4 is pushed towards the positioning block 2 under the guidance of the slider 7 and guide rail 8; at this time, the urethane adhesive 5 attached to the bottom of the pressure block 4 or the side facing the product 6 to be polished will contact the product 6 to be polished and form a stable clamping force. Because of its elasticity, the urethane adhesive 5 can effectively reduce indentations or damage to the workpiece surface during positioning and clamping.

[0034] When clamping the workpiece, the operator can first release the mechanical quick clamp 3, so that the pressure block 4 is in a position away from the positioning block 2. Then, place the product 6 to be polished near the stop edge 21 of the positioning block 2, ensuring that one side is in close contact with the stop edge 21. Subsequently, the operator uses the mechanical quick clamp 3 to push the pressure block 4 toward the product 6 to be polished, achieving a stable clamping effect with the cushioning of the urethane rubber 5. For higher precision or foolproof positioning, positioning pins or positioning grooves can be added to the positioning block 2 or the pressure block 4 to constrain the product 6 to be polished to the correct assembly direction and position. If the height or size of the workpiece varies greatly, the height can be finely adjusted by adding or removing the heightening block 1 or adding shims to ensure that the product 6 to be polished is within the appropriate polishing range.

[0035] During operation, the clamping block 4 keeps the product 6 to be polished stably clamped, while the polishing machine polishes or grinds the surface of the product. After polishing is completed, the operator releases the mechanical quick clamp 3 again to quickly remove the finished product 6, completing one work cycle. Compared with the traditional complex multi-point clamping or fixed bolt clamping method, this invention greatly simplifies the operation process, reduces labor costs and improves work efficiency. At the same time, the urethane adhesive 5 effectively protects the appearance quality of the product 6 to be polished, further reducing the defect rate and subsequent rework.

[0036] In summary, this invention, through the ingenious combination of components such as the heightening block 1, positioning block 2, edge guard 21, mechanical quick clamp 3, pressure block 4, urethane adhesive 5, slider 7, and guide rail 8, achieves a simple structure, convenient operation, excellent protective capabilities, and wide applicability for a flat polishing fixture. While ensuring efficient production and polishing quality, it also significantly reduces problems such as workpiece damage or unstable clamping, making it suitable for widespread application in machining and surface treatment fields requiring high precision and efficiency. Those skilled in the art can adjust or improve the structural form and component combination of this invention according to actual production needs, but such adjustments or improvements do not affect the technical effects to be achieved by this invention, nor do they exceed the spirit and scope of this invention.

[0037] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
