Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial processing technology, and more specifically, to a floating plate processing upper and lower connection adjustment device. Background Technology
[0002] Floating plates are adjustable components commonly used in precision mechanical assemblies or fixtures. Their machining requires a balance between high precision and flexibility. Materials such as aluminum alloys and stainless steel are typically used, and the main structure is completed through milling, drilling, and grinding. Key considerations include ensuring flatness, hole accuracy, and surface roughness to meet the fitting requirements of the floating mechanism (such as guide grooves and spring grooves). Strict control of clamping forces is necessary during machining to prevent deformation. Staged machining (rough machining followed by stress relief treatment and then finish machining) is employed to reduce residual stress in the material.
[0003] When processing, the adjustment requirements of the upper and lower connecting parts of the floating plate fixture are taken into account. The fixture usually needs to rely on tools to adjust the axial position of the connecting parts. However, when using the existing adjustment structure that can meet the internal adjustment, the overall axial stability and structural strength of the adjustment structure are limited due to the mobility of the adjustment end, making it difficult for the existing upper and lower connecting adjustment parts to meet the rigid connection requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing floating plate clamp connection structure is affected by mobility, resulting in poor axial structural strength and stability. In view of the problems existing in the prior art, a floating plate processing upper and lower connection adjustment device is provided.

[0006] The end of the sliding shaft is fixed with a shaft disc that slides with the shaft member, and corner seats are fixed at the four corners of the shaft disc. An inner guide rail seat is provided at the outer end of the corner seat, and a rail groove is formed between the inner guide rail seat and the shaft member.

[0013] The beneficial effects of this utility model are:

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-3The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.
[0021] A floating plate processing upper and lower connection adjustment device includes a shaft member 1 and a connecting shaft seat 2. The shaft member 1 and the connecting shaft seat 2 are axially connected shaft joint structures. The ends of the shaft member 1 and the ends of the connecting shaft seat 2 are provided with a connected sliding shaft member 12 and an adjusting shaft column 13. The connecting shaft seat 2 is fixed with a mounting plate 3 at one end relative to the shaft member 1, and the shaft member 1 is fixed with an angle steel member 4 at one end relative to the connecting shaft seat 2.
[0022] The end of the sliding shaft 12 is fixed with a shaft disk 11 that slides with the shaft rod 1, and corner seats 10 are fixed at the four corners of the shaft disk 11. An inner guide rail seat 6 is provided at the outer end of the corner seat 10, and a rail groove is formed between the inner guide rail seat 6 and the shaft rod 1. A cylinder 9 is axially embedded at the connection end between the angle steel 4 and the shaft rod 1, and a valve pipe 8 is connected to the outside of the cylinder 9. An expansion shaft 5 that communicates with the cylinder 9 is fixed on the inner guide rail seat 6, and a bolt seat 7 is fixed between the expansion shaft 5 and the angle steel 4.
[0023] An axial locking structure is provided between the bearing seat 2 and the adjusting shaft column 13, and the locking structure of the adjusting shaft column 13 is matched with the axial position of the adjusting shaft column 13.
[0024] The device uses an axially connected shaft 1 and a shaft seat 2 as the upper and lower connection structures between the machining fixtures, respectively. The mounting plate 3 and the outer end of the angle steel 4 at the end are used as bolted structures for the fixture connection ends.
[0025] The axial adjustment of the structure is achieved by the axial movement of the sliding shaft 12 and the adjusting shaft column 13 at its connecting end. The default axial position of the sliding shaft 12 will lock and fix the axial angle direction of the adjusting shaft column 13. The axial position of the sliding shaft 12 is controlled by the air pressure of the cylinder 9. The cylinder 9 is connected to the air supply source through the valve pipe 8 connected to the outer end. The gas fills the air rod 9 to increase the air pressure. The air pressure change will act on the expansion shaft 5 through the inner guide seat 6. One end of the expansion shaft 5 is fixed to the angle steel 4 through the bolt seat 7, so that when the expansion shaft 5 expands, it will be reflected to the inner guide seat 6 at the other end, so that the inner guide seat 6 will make axial displacement along the rail groove on the surface of the shaft member 1. Each corner is provided with an inner guide seat 6 with a relative axial direction, and they are all linked through the shaft plate 11. The shaft plate 11 is moved by the displacement of the inner guide seat 6, so that the connected sliding shaft 12 makes axial displacement at the end of the shaft member 1 to adjust the axial position of the structure.
[0026] The locking structure includes a toothed seat 14 and a toothed head 15 that are axially connected. The toothed head 15 is fixed to the end of the adjusting shaft column 13, and a shaft is provided through the toothed seat 14 and the mounting plate 3. When the cylinder 9 retracts, the locking structure can disengage the adjusting shaft column 13 and the toothed head 15 connected at the end sequentially by the retraction of the sliding shaft 12. The axial angle position of the external connecting shaft seat 2 relative to the shaft member 1 can be easily changed by the screwing action or external adjustment. After the cylinder 9 feeds and expands, the toothed head 15 is reinserted into the toothed seat 14 to lock the adjusting shaft column 13 and the connecting shaft seat 2.
[0027] Compared to traditional axial adjustment devices, this device structure uses an expansion shaft 5 arranged laterally outside the shaft diameter and an inner guide rail seat 6. The inner guide rail seat 6 is radially limited by the groove of the shaft member 1 to lock the axial angle of the connection end between the shaft member 1 and the shaft seat 2. The axial expansion of the cylinder 9 is used to axially reinforce the locking end, which improves the strength in the axial position and the stability in the radial position of the structure. The interaction of the internal structures makes it easy to ensure the connection stability of the upper and lower connection parts during use, and also facilitates secondary adjustment in the later stage.
[0028] Furthermore, a window is opened on the side end of the shaft seat 2, and the toothed seat 14 protrudes at the window position to form an outer plate 16. The window end makes it convenient for the operator to use tools to screw the internal toothed seat 14, which improves the adjustment accuracy compared to manually screwing the external shaft seat 2 and the shaft member 1.
[0029] Furthermore, the inner guide rail seat 6 and the corner seat 10 have an angled shaft connection structure, such as... Figure 1 , 2 As shown, the corner seat 10 and the inner guide rail seat 6 form an angled shear structure, which can improve the axial structural strength between the inner guide rail seat 6 and the corner seat 10 and the shaft disk 11.
[0030] Furthermore, a matching groove is provided between the bolt seat 7 and the shaft member 1. The groove structure further limits the axial displacement of the bolt seat 7 and the expansion shaft 5 to match the displacement of the inner guide seat 6, thereby improving the movement accuracy and stability of the middle section between the inner guide seat 6 and the expansion shaft 5.
[0031] Furthermore, a groove structure with a concave-convex fit is provided on the inner side of the connecting end of the shaft member 1 and the connecting shaft seat 2. Through the groove structure with a concave-convex fit, the axial connection accuracy of the shaft member 1 and the connecting shaft seat 2 can be improved when they are in the minimum contracted axial position. Specific implementation examples:
[0033] The device uses the mounting plate 3 installed outside the shaft members 1 at both ends, the connecting shaft seat 2, and the outer end of the angle steel member 4 as the bolt connection structure for the upper and lower connecting ends of the floating plate processing fixture;
[0034] The axial adjustment of the structure is achieved by the axial movement of the sliding shaft 12 and the adjusting shaft column 13 at its connecting end. The default axial position of the sliding shaft 12 will lock and fix the axial angle direction of the adjusting shaft column 13. The axial position of the sliding shaft 12 is controlled by the air pressure of the cylinder 9. The cylinder 9 is connected to the air supply source through the valve pipe 8 connected to the outer end. The gas fills the air rod 9 to increase the air pressure. The air pressure change will act on the expansion shaft 5 through the inner guide seat 6. One end of the expansion shaft 5 is fixed to the angle steel 4 through the bolt seat 7, so that when the expansion shaft 5 expands, it will be reflected to the inner guide seat 6 at the other end, so that the inner guide seat 6 will make axial displacement along the rail groove on the surface of the shaft member 1. Each corner is provided with an inner guide seat 6 with a relative axial direction, and they are all linked through the shaft plate 11. The shaft plate 11 is moved by the displacement of the inner guide seat 6, so that the connected sliding shaft 12 makes axial displacement at the end of the shaft member 1 to adjust the axial position of the structure.
[0035] The axial angle is released by the cylinder 9 contracting to unlock the axial lock of the locking structure. At this time, the contraction of the sliding shaft 12 will cause the adjusting shaft 13 and the tooth head 15 to disengage from the toothed seat 14. By turning the outer disk 16 with a tool or by externally adjusting the axial angle between the shaft 1 and the connecting shaft seat 2, the axial angle position of the clamp structure connected at both ends of the shaft 1 and the connecting shaft seat 2 can be changed. After the cylinder 9 feeds and expands, the tooth head 15 is reinserted into the toothed seat 14 to lock the adjusting shaft 13 and the connecting shaft seat 2.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
