Description

Technical Field

[0001] The utility model relates to the technical field of mechanical devices, and particularly relates to a sliding pressing device. Background Art

[0002] When a workpiece has holes or grooves and is polished by abrasive flow, abrasive particles or impurities will remain. At this time, the workpiece needs to be fixed to a workbench or a carrier, and the workpiece is cleaned by gas or liquid. The existing fixing method for the workpiece is to fix the workpiece by using an elbow clamp or a screw, and sometimes tools such as a wrench are also needed. The operation process is troublesome and the efficiency is low. Moreover, the elbow clamp is generally a standard purchased part, and the chuck has no protection measures, which is easy to scratch or press the surface of the workpiece.

[0003] The purpose of the utility model is to provide a sliding pressing device that can quickly fix and release a workpiece. Summary of the Utility Model

[0004] The main technical problem solved by the utility model is to provide a sliding pressing device with a simple and ingenious structure, which can quickly fix a workpiece on a guide rail and is convenient, simple and fast to operate.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a sliding pressing device, including two groups of sliding pressing mechanisms. The workpiece is placed above the guide rail, and the sliding pressing mechanism can slide along the guide rail and press the workpiece against the upper surface of the guide rail from above;

[0006] The sliding pressing mechanism includes a support frame, a pressing component, an upper support pulley and a lower support pulley installed on the support frame. The guide rail passes through between the upper support pulley and the lower support pulley. The upper support pulley and the lower support pulley form a stable triangular structure, and the distance between the upper support pulley and the lower support pulley can be adjusted through an adjusting structure;

[0007] The pressing component includes a pressing screw rod and a pressing block. The upper end of the pressing screw rod passes through the upper part of the support frame and the lower end fixes the pressing block. The rotation of the pressing screw rod drives the pressing block to move up and down.

[0008] Further, the triangular structure means that there is one upper support pulley and two lower support pulleys; or there are two upper support pulleys and one lower support pulley.

[0009] Further, the adjusting structure includes a fixing block, a tensioning screw and a pulley support plate. The fixing block is fixedly installed at the lower part of the support frame. The tensioning screw passes through the fixing block and the lower end is screwed into the pulley support plate. By rotating the tensioning screw, the pulley support plate is driven to move up and down.

[0010] Furthermore, the pressing block is a disc-shaped nylon block.

[0011] Furthermore, both the upper support pulley and the lower support pulley are rollers with bearings.

[0012] Furthermore, the upper end of the pressing screw rod is connected to a hand wheel.

[0013] Furthermore, the workpiece is a plate-shaped workpiece, and the guide rail is a sheet metal square tube.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present utility model includes two sets of sliding pressing mechanisms. The workpiece is placed above the guide rail. The sliding pressing mechanism can slide along the guide rail and press the workpiece against the upper surface of the guide rail from above; by rotating the hand wheel, the workpiece can be quickly pressed against the guide rail. Therefore, the present utility model can achieve quick fixation of the workpiece, and the fixation is stable; the structure is concise and the design is ingenious, which can quickly fix the workpiece on the guide rail, and the operation is convenient, simple and fast;

[0016] Moreover, by rotating the hand wheel, it can be quickly rotated and pressed. By rotating the hand wheel, the pressing screw rod is driven to rotate, and finally the quick pressing of the pressing block is realized, which saves time and effort;

[0017] Moreover, the upper support pulley and the lower support pulley form a stable triangular structure. The use of the triangular structure is more stable and has a higher cost performance. If there is one support pulley provided at both the upper and lower parts, the stability is not good; if there are two support pulleys provided at both the upper and lower parts, it is unnecessary and will increase the cost.

[0018] The above description is only an overview of the technical solution of the present utility model. In order to be able to understand the technical means of the present utility model more clearly and to be implemented in accordance with the content of the description, the following takes the preferred embodiments of the present utility model and coordinates with the attached drawings to describe in detail as follows. Description of the Drawings

[0019] Figure 1 is one of the structural schematic diagrams of the present utility model;

[0020] Figure 2 is the other structural schematic diagram of the present utility model;

[0021] The marks of each part in the drawings are as follows:

[0022] Guide rail 10, sliding pressing mechanism 20, workpiece 30;

[0023] Support frame 1, hand wheel 2, pressing screw rod 3, pressing block 4, upper support pulley 5, lower support pulley 6, pulley support plate 7, fixing block 8, tensioning screw 9. Detailed Embodiments

[0024] The following specific embodiments illustrate the specific implementation manners of the present utility model. Those skilled in the art can easily understand the advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented in other different ways, that is, without departing from the scope disclosed by the present utility model, different modifications and changes can be made.

[0025] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the drawings and have no special meaning, nor are they used to limit the protection scope of the present utility model.

[0026] Embodiment: A sliding pressing device, as Figure 1 and Figure 2 shown, includes two sets of sliding pressing mechanisms 20. The workpiece is placed above the guide rail 10, and the sliding pressing mechanism can slide along the guide rail and press the workpiece against the upper surface of the guide rail from above;

[0027] The sliding pressing mechanism 20 includes a support frame 1, a pressing component installed on the support frame, an upper support pulley 5 and a lower support pulley 6. The guide rail passes through between the upper support pulley and the lower support pulley. The upper support pulley and the lower support pulley form a stable triangular structure, and the distance between the upper support pulley and the lower support pulley can be adjusted through an adjusting structure;

[0028] The pressing component includes a pressing screw rod 3 and a pressing block 4. The upper end of the pressing screw rod passes through the upper part of the support frame and the lower end fixes the pressing block. The rotation of the pressing screw rod will drive the pressing block to move up and down.

[0029] The triangular structure means that there is one upper support pulley and two lower support pulleys; or there are two upper support pulleys and one lower support pulley. In the drawings of this embodiment, the former is adopted.

[0030] Adopting a triangular structure is more stable and has a higher cost performance. If there is one support pulley at both the upper and lower parts, the stability is not good; if there are two support pulleys at both the upper and lower parts, it is unnecessary and will increase the cost.

[0031] The adjusting structure includes a fixing block 8, a tensioning screw 9 and a pulley support plate 7. The fixing block is fixedly installed at the lower part of the support frame. The tensioning screw passes through the fixing block and the lower end is screwed into the pulley support plate. By rotating the tensioning screw, the pulley support plate is driven to move up and down. The adjusting structure is designed because the guide rail itself has dimensional and shape errors. Through this structure, the up and down position of the pulley support plate can be adjusted, and then the lower support pulley will be driven to move up and down, that is, the distance between the upper support pulley and the lower support pulley can be adjusted, which can better match the dimensional error of the guide rail. After replacing the guide rail with different heights, the device can also be used, and the versatility and adaptability are better.

[0032] In this embodiment, the pressing block is a disc-shaped nylon block. Using a material with certain elasticity itself and a disc-shaped nylon block can better avoid scratching the surface of the workpiece.

[0033] In this embodiment, both the upper support pulley and the lower support pulley are rollers with bearings. This makes the process of the sliding pressing mechanism sliding along the guide rail smoother.

[0034] In this embodiment, the upper end of the pressing screw rod is connected to the hand wheel 2. By setting the hand wheel, the up and down movement process of the pressing block is more labor-saving.

[0035] The workpiece is a plate-shaped workpiece, and the guide rail is a sheet metal square tube, but it is not limited thereto.

[0036] The working principle and process of the present utility model:

[0037] After the sliding pressing mechanism 2 moves along the guide rail 1 to the position where the workpiece 3 is located, rotate the hand wheel to press the workpiece and fix the workpiece here. Specifically:

[0038] The support frame 1 is used to fix the workpiece. The pressing screw rod 3 is screwed into the support frame. The hand wheel 2 is fixed to the pressing screw rod 3, and the pressing screw rod 2 is fixed to the pressing block 4. In this way, the hand wheel can rotate the screw rod to press the object. The upper support pulley 5 contacts the upper plane of the guide rail. The pulley support plate 7 is fixed to the two lower support pulleys 6. After being installed on the slide rail, the fixing block 8 is locked on the support frame 1. The tensioning screw 9 is locked with the pulley support plate 7 to make the lower support pulley 6 contact the slide rail, and the pulley support plate 7 is locked on the support frame 1 with screws. In this way, the sliding pressing mechanism can slide on the guide rail.

[0039] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structures made by using the specification and drawings of the present utility model, directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
