Abstract
Description
Technical Field
[0001] This utility model relates to the field of bar stock processing equipment technology, and in particular to a pressure plate adjustment structure that eliminates gaps. Background Technology
[0002] Bar stock processing is the process of processing metal, wood, stone and other bar stock into products that meet design requirements through various processes. Its core process involves multiple steps such as cutting, forming and surface treatment.
[0003] When machining the surface or end face of bar stock, the bar stock needs to be pressed onto the worktable for surface treatment. Since the outer surface of the bar stock is arc-shaped and uneven before processing, when the pressure plate is pressed tightly against the bar stock for surface treatment, there is a gap between the pressure plate and the bar stock, resulting in insufficient force acting on the surface of the bar stock. This leads to displacement of the bar stock during surface processing, increasing the difficulty and accuracy of bar stock surface processing.
[0004] Therefore, those skilled in the art are dedicated to developing a pressure plate adjustment structure that eliminates gaps, which facilitates the lower pressure plate to tightly press the bar stock and reduce slippage. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a pressure plate adjustment structure with gap elimination, which is conducive to the lower pressure plate pressing the bar material tightly and reducing slippage.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] A pressure plate adjustment structure with gap elimination, comprising:
[0008] The lower pressure plate has a support column assembly connected to its upper end via an elastic component. The lower pressure plate has a pressing surface with an installation groove on it, and multiple elastic pressure block assemblies are installed in the installation groove.
[0009] The beneficial effects of adopting the above solution are: by cooperating with the upper end of the lower pressure plate and the elastic component and the support column component, and by setting multiple elastic pressure block components in the mounting groove on the pressing plane of the lower pressure plate, the problem of gap between the lower end face of the lower pressure plate and the bar can be effectively solved, so that multiple elastic pressure block components can be tightly fitted to the bar respectively, so that the force can be evenly and fully applied to the surface of the bar during surface treatment, avoiding the uneven force caused by the gap preventing some force from being transmitted to the bar.
[0010] The tightly fitting pressure plate can firmly fix the bar stock on the operating table, greatly reducing the possibility of bar stock slippage during bar stock surface processing, thereby reducing the difficulty of bar stock surface processing, helping to improve processing accuracy and quality, ensuring product consistency and stability, and effectively meeting the needs of the bar stock processing field for pressure plate adjustment structure.
[0011] Based on the above technical solution, the present invention can be further improved as follows.
[0012] Furthermore, the elastic pressure block assembly includes an elastic pressure block located within the mounting groove. The elastic pressure block is connected to the lower pressure plate via connecting screws, and an elastic component is installed between the lower pressure plate and the elastic pressure block.
[0013] The beneficial effects of adopting the above-mentioned further solution are: the elastic pressure block is located in the mounting groove and is connected to the lower pressure plate by connecting screws, and an elastic component is installed between the two, so that the elastic pressure block can flexibly adapt to the unevenness of the bar material surface and fit tightly against the bar material, thereby more effectively eliminating gaps. At the same time, during the pressing process, the elastic component can provide a stable elastic force to ensure the pressing effect of the elastic pressure block on the bar material and improve the stability of the bar material during the processing.
[0014] Furthermore, the elastic component includes a compression spring, a fixing groove is provided on the lower pressure plate, the compression spring is disposed in the fixing groove, the two ends of the compression spring abut against the bottom of the fixing groove and the elastic pressure block respectively, and a locking component is also installed between the elastic pressure block and the fixing groove.
[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the elastic component uses a compression spring and is set in the fixed groove on the lower pressure plate. The two ends of the compression spring abut against the bottom of the fixed groove and the elastic pressure block, respectively. This allows for more precise control of the force on the elastic pressure block, making the pressure of the elastic pressure block on the bar stock more uniform and adjustable. Furthermore, the locking component installed between the elastic pressure block and the fixed groove can securely lock the elastic pressure block after it reaches the appropriate position, further enhancing the stability of the elastic pressure block during operation and preventing it from shifting or loosening under pressure.
[0016] Furthermore, the locking assembly includes a countersunk hole provided on the elastic pressure block, through which a countersunk screw passes and is threaded to the bottom of the fixing groove.
[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: The locking assembly adopts a countersunk hole and countersunk screw structure. The countersunk screw passes through the countersunk hole on the elastic pressure block and is threaded to the bottom of the fixing groove. This not only enables a stable and reliable connection between the elastic pressure block and the lower pressure plate, ensuring that there will be no loosening during the clamping of the bar, but also makes the connection part flush with the surface of the lower pressure plate, which is conducive to maintaining the overall flatness and aesthetics of the equipment, and also facilitates subsequent disassembly and maintenance.
[0018] Furthermore, the elastic component includes a guide post and a connecting plate. One end of the guide post is fixedly connected to the lower pressure plate, and the connecting plate is provided with a guide hole. The other end of the guide post passes through the guide hole and is connected to a fixing bolt.
[0019] The guide post is fitted with a compression spring, and the two ends of the compression spring abut against the upper side of the lower pressure plate and the lower side of the connecting plate, respectively.
[0020] The beneficial effects of adopting the above-mentioned further solution are as follows: The elastic component consists of a guide post, a connecting plate, and a compression spring. One end of the guide post is fixedly connected to the lower pressure plate, and the other end passes through the guide hole on the connecting plate and is connected by a fixing bolt. The cooperation between the guide post and the guide hole ensures the linearity of the movement trajectory of the connecting plate during the entire elastic adjustment process, thereby improving the stability and reliability of the structure. The compression spring, which is sleeved on the guide post, has its two ends abutting against the upper side of the lower pressure plate and the lower side of the connecting plate, respectively. It can provide uniform elastic support force in the vertical direction, making it convenient to adjust the height according to the diameter and shape of the bar stock, so as to better adapt to the clamping requirements under different conditions.
[0021] Furthermore, the support column assembly includes a support column, which is connected to the connecting plate via a connecting block.
[0022] The beneficial effects of adopting the above-mentioned further solution are as follows: the support column and the connecting plate are connected by a connecting block. This structure enhances the support stability of the support column on the lower pressure plate, making the entire pressure plate adjustment structure more stable during operation. At the same time, the connecting block also facilitates operations such as adjusting the height of the support column, which is beneficial for adapting to the processing needs of bars of different diameters and improves the versatility and flexibility of the equipment.
[0023] Furthermore, the upper end of the connecting plate has a connecting hole, and the connecting block is provided with a strip groove, through which the adjusting screw passes and connects to the connecting hole.
[0024] The advantages of adopting the above-mentioned further solution are: the connecting hole at the upper end of the connecting plate mates with the slot on the connecting block, and the adjusting screw passes through the slot and connects to the connecting hole, making the height adjustment of the support column more flexible and convenient. When processing bars of different diameters or shapes, simply loosen the adjusting screw, move the connecting block along the slot to the appropriate position, and then tighten the screw to achieve precise adjustment of the support column height, thereby better meeting different processing requirements and improving the adaptability and practicality of the equipment.
[0025] Furthermore, a lifting assembly is also provided on the support column.
[0026] The beneficial effects of adopting the above-mentioned further solution are: the lifting component installed on the support column adds a lifting function to the pressure plate adjustment structure, allowing the entire pressure plate to be adjusted in height according to actual processing needs. When dealing with bars of different diameters or requiring different processing steps, there is no need to frequently change support columns or pressure plates of different heights; a simple operation using the lifting component allows for quick adjustment to the appropriate position, greatly improving work efficiency and ease of operation.
[0027] Furthermore, the lifting assembly includes a first support column and a second support column. The first support column and the second support column are respectively provided with a first internal thread and a second internal thread. The first internal thread and the second internal thread rotate in opposite directions. The first support column and the second support column are connected by an adjusting screw. Rotating the adjusting screw causes the first support column and the second support column to move closer to each other or further away from each other.
[0028] The beneficial effects of adopting the above-mentioned further solution are as follows: The lifting assembly consists of a first support column, a second support column, and an adjusting screw. The first and second support columns are respectively provided with internal threads of opposite directions and are connected by the adjusting screw. When the adjusting screw is rotated, the first and second support columns can move closer to or further away from each other, achieving precise control and synchronous adjustment of the support column height. This not only ensures that the heights of the left and right support columns remain consistent, improving the accuracy and stability of the pressure plate adjustment, but also simplifies operation, saves effort, and effectively enhances the performance and ease of operation of the equipment.
