Description

Technical Field

[0001] The utility model relates to the technical field of linear slides, in particular to a linear slide with a pressurizing structure. Background Art

[0002] A linear slide is a device used to achieve linear motion control, and functions such as precise control of distance and speed and position feedback detection can be realized through a controller.

[0003] A linear slide consists of a base, a driver, a lead screw, a nut, and a positioning table. In order to ensure the stability of the positioning table, a limiting table is provided on the nut to guide the moving direction of the nut when the limiting table slides in the base. A sliding groove for guiding the limiting table is opened on the linear slide. At present, most of the limiting table and the base are made of steel structures, which results in a large amount of noise when the limiting table slides on the base. At the same time, the long-term friction between the limiting table and the base causes a certain degree of wear on both the limiting table and the base. Since no protective component is provided on the limiting table, the limiting table is extremely prone to damage during movement, thereby affecting the service life of the linear slide. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of large friction noise between the limiting table and the base when the linear slide is operating in the prior art, and to propose a linear slide with a pressurizing structure.

[0006] A linear slide with a pressurizing structure includes a slide body. The slide body includes a base, a driver, a lead screw, a nut, and a positioning table. The positioning table is arranged on the nut. Symmetrically arranged limiting tables are fixedly installed on the nut, and a sliding groove corresponding to the limiting table is opened on the base. A support plate is fixedly installed on the nut, and a positioning rod and a positioning block integrally connected are installed on the support plate. A bracket corresponding to the limiting table is fixedly installed on the positioning block. Symmetrically arranged sliders are slidably sleeved in the bracket, and springs are welded between the sliders and the bracket. A support pad extending into the sliding groove is fixedly installed on the slider.

[0007] Preferably, one end of the positioning rod is provided with a thread, and a bolt corresponding to the support plate is threadedly connected to the positioning rod.

[0008] Preferably, a positioning groove for guiding the slider is opened on the bracket, and the spring is horizontally welded.

[0009] Preferably, the bracket is of a U-shaped structure, and the two support pads are vertically arranged corresponding to each other.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model arranges a support plate on the limit platform, so that the support plate drives the bracket to extend to the limit platform and surround the limit platform, and then applies pressure to the movable plate, so that the support pad can be moved out of the bracket and extend into the slide groove, and the fixing bolts and bolts are used to enable the support pad to be quickly installed on the limit platform.

[0014] 2.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4, A linear slide table with a pressurizing structure, including a slide table main body. The slide table main body includes a base 1, a driver, a lead screw 2, a nut 3, and a positioning table. The positioning table is arranged on the nut 3. Symmetrically arranged limiting tables 4 are fixedly installed on the nut 3, and a chute 5 corresponding to the limiting table 4 is opened on the base 1. After the driver is powered on, it drives the lead screw 2 to rotate. When the lead screw 2 rotates, it drives the nut 3, the limiting table 4, and the positioning table to move. This technical solution is the prior art and will not be elaborated here;

[0022] A support plate 6 is fixedly installed on the nut 3, and a positioning rod 7 and a positioning block are integrally connected and installed on the support plate 6. A thread is provided at one end of the positioning rod 7, and a bolt corresponding to the support plate 6 is threadedly connected to the positioning rod 7;

[0023] A bracket 8 corresponding to the limiting table 4 is fixedly installed on the positioning block. Symmetrically arranged sliders 9 are slidably sleeved in the bracket 8, and a spring 10 is welded between the slider 9 and the bracket 8. A positioning groove for guiding the slider 9 is opened on the bracket 8. The positioning groove plays a role in guiding the slider 9, enabling the slider 9 to smoothly pull the support pad 11 when moving;

[0024] The spring 10 is horizontally welded. A support pad 11 extending into the chute 5 is fixedly installed on the slider 9. The bracket 8 is in a U-shaped structure, and the two support pads 11 are correspondingly arranged vertically;

[0025] By extending the positioning rod 7 onto the support plate 6, the positioning rod 7 drives the positioning block and the bracket 8 to move. The U-shaped structure of the bracket 8 can surround the limiting table 4, thereby reducing the friction between the limiting table 4 and the base 1;

[0026] Symmetrically arranged limiting blocks 12 are slidably sleeved in the bracket 8, and a connecting rod 14 is connected between the limiting block 12 and the support pad 11. A moving plate 13 is fixedly installed on the limiting block 12. A limiting groove for guiding the limiting block 12 is opened on the bracket 8. The two ends of the connecting rod 14 are respectively pin-connected to the middle of the limiting block 12 and the support pad 11. The moving plate 13 is in an L-shaped structure, and a positioning bolt corresponding to the bracket 8 is threadedly connected to the moving plate 13. Supplementary note, the support pad 11 is made of rubber. By providing a rubber pad extending into the chute 5, the pressure between the base 1 and the limiting table 4 can be increased, the friction coefficient between the base 1 and the limiting table 4 can be reduced, and the limiting table 4 can move smoothly;

[0027] By applying pressure to the two movable plates 13, the movable plates 13 drive the limit blocks 12 to move toward each other. When the limit blocks 12 move toward each other, the pulling connecting rod 14 is deflected. The position difference generated when the connecting rod 14 is deflected can resist the support pad 11, so that the support pad 11 can be moved out of the bracket 8 and extend into the slide groove 5. The mutual cooperation between the support pad 11 and the slide groove 5 can reduce noise, thereby improving the service life of the slide body.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] When the slide body needs to be used;

[0030] The positioning rod 7 is extended into the support plate 6, the positioning rod 7 drives the positioning block to extend into the limit platform 4, the positioning block drives the bracket 8 to extend onto the limit platform 4, and the positioning rod 7 and the support plate 6 are connected with bolts;

[0031] The two moving plates 13 are pressed, so that the moving plates 13 drive the limit blocks 12 to slide in the limit grooves when moving, and the limit blocks 12 pull the connecting rods 14 to deflect when sliding toward each other, and the position difference generated when the connecting rods 14 deflect can exert pressure on the support pads 11;

[0032] When the support pad 11 moves, the slider 9 slides in the positioning groove, and the spring 10 is stressed, so that the support pad 11 moves out of the bracket 8 and extends into the slide groove 5. When the position of the support pad 11 is determined, the positioning bolt is used to connect the moving plate 13 and the bracket 8;

[0033] When the driver is powered on, it drives the screw rod 2 to rotate. When the screw rod 2 rotates, it drives the nut 3 to move. When the nut 3 moves, it drives the positioning platform to move. The nut 3 drives the limit platform 4, the bracket 8, and the support pad 11 to move. When the support pad 11 slides in the slide groove 5, it can reduce noise and wear.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
