Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a sliding table locking mechanism. Background Art

[0002] The slide locking mechanism is mainly used on the guide rail to lock the slide or slider, so that the slide or slider is fixed, which facilitates the position adjustment of the components on the slide or slider. Most slide locking methods are to configure a locking bolt on the slide or slider, and the locking bolt is rotated to make the end of the locking bolt contact with the guide rail to achieve the locking and fixation of the slide or slider. However, the main defect of this structure is that the end of the locking bolt will leave a concave mark on the guide rail after contacting the guide rail, which greatly affects the flatness of the guide rail surface. After a period of use, the sliding of the slide or slider will be not smooth enough, thus affecting the working performance of the slide or slider. At the same time, the locking bolt is generally operated manually, which is very time-consuming and labor-intensive and inefficient. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a slide locking mechanism, the purpose of which is to make the locking operation convenient and the locking reliable.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a slide locking mechanism, comprising a guide rail and a slide, the slide can be slidably mounted on the guide rail, a lock seat corresponding to the guide rail is mounted on the slide, the lock seat is provided with a clearance groove for the guide rail to pass through, through holes are respectively provided on both sides of the clearance groove on the lock seat, a limit lock block sliding along the through hole is provided in one through hole, a locking block sliding along the through hole is provided in the other through hole, a screw is rotatably mounted on the slide, the screw passes through the eccentric position of the limit lock block and is threadedly connected to the eccentric position of the locking block, a limit ring is also provided on the peripheral wall of the screw, the other end of the limit lock block away from the clearance groove contacts the limit ring, when a driving device drives the screw to rotate, the screw drives the locking block to extend and retract, so as to realize the clamping or loosening of the guide rail by the locking block and the limit lock.

[0005] The driving device comprises a cylinder and a swing rod, one end of the swing rod is connected to the end of the screw rod, and the other end of the swing rod is connected to the piston rod of the cylinder.

[0006] The driving device is a servo motor, and the output shaft of the servo motor is connected to the screw rod.

[0007] The upper end surface of the slide is equipped with a secondary guide rail, on which a secondary slide sliding along the secondary guide rail is installed, and a motor is installed on the slide, on which an output shaft of the motor is connected a lead screw, which is threadedly connected to the secondary slide.

[0008] The beneficial effect of the utility model is that when it is necessary to lock and fix the slide table, the driving device drives the screw to rotate so that the locking block moves along the screw toward the direction of the limit locking block. When the locking block contacts the guide rail, the rotation of the screw will also drive the screw to move axially, so that the limit locking block is driven to move toward and contact the guide rail, thereby realizing the clamping of the guide rail by the limit locking block and the locking block, thus achieving the technical purpose of making the locking operation convenient and the locking reliable.

DETAILED DESCRIPTION

[0015] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0016] like Figure 1 — Figure 4As shown, the present embodiment discloses a slide locking mechanism, comprising a guide rail 1 and a slide 2, the slide 2 being slidably mounted on the guide rail 1, a lock seat 3 corresponding to the guide rail 1 being mounted on the slide 2, the lock seat 3 being provided with a clearance groove for the guide rail 1 to pass through, through holes 31 being respectively arranged on both sides of the clearance groove on the lock seat 3, a limiting lock block 4 sliding along the through hole 31 being arranged in one through hole 31, a locking block 5 sliding along the through hole 31 being arranged in the other through hole 31, a screw 6 being rotatably mounted on the slide 2, the screw 6 passing through the eccentric position of the limiting lock block 4 and being screwed to the eccentric position of the locking block 5, so that the screw 6 will not be brought into engagement during rotation. The movable limit lock block 4 and the locking block 5 rotate in the through hole 31, achieving the technical effect that the screw 6 drives the limit lock block 4 and the locking block 5 to slide along their respective through holes 31. A limit ring 61 is also provided on the peripheral wall of the screw 6, and the other end of the limit lock block 4 away from the yield groove contacts the limit ring 61, so that the screw 6 rotates to drive the locking block 5 to move toward the limit lock block 4, and the limit lock block 4 can be stopped by the limit ring 61, so that the two can move away from or close to the guide rail 1 respectively. When a driving device 7 drives the screw 6 to rotate, the screw 6 drives the locking block 5 to extend and retract, thereby achieving the clamping or loosening of the guide rail 1 by the locking block 5 and the limit lock.

[0017] The first embodiment of the driving device 7 includes a cylinder 71 and a rocker arm 72, one end of the rocker arm 72 is connected to the end of the screw rod 6, and the other end of the rocker arm 72 is movably connected to the piston rod of the cylinder 71, so that the extension and retraction of the cylinder 71 can drive the rocker arm 72 to swing, and the rocker arm further drives the screw rod 6 to rotate. The rotation of the screw 6 can cause the threaded transmission locking block thereof to extend and retract, making the control of the screw rod 6 more precise and reliable.

[0018] The second implementation of the driving device 7 includes a servo motor, the output shaft of which is connected to the screw rod 6, which also makes the control of the screw rod 6 more accurate and reliable.

[0019] A secondary guide rail 10 is installed on the upper end surface of the slide 2, and the secondary guide rail 10 is at a horizontal vertical angle with the guide rail 1 below. A secondary slide 20 is installed on the secondary guide rail 10 to slide along it. A motor 30 is installed on the slide 2, and a lead screw is connected to the output shaft of the motor 30. The lead screw is threadedly connected to the secondary slide 20. Through this structure, the installation components on the secondary slide 20 can be adjusted in any horizontal direction, effectively improving the convenience of operation of the installation components.

[0020] When the above technical scheme is adopted, when it is necessary to lock and fix the slide 2, the driving device 7 drives the screw 6 to rotate so that the locking block 5 moves along the screw 6 toward the limit lock block 4. When the locking block 5 contacts the guide rail 1, the rotation of the screw 6 will also drive the screw 6 to move axially, so that the drive limit block moves and contacts the guide rail 1, thereby realizing the clamping of the guide rail 1 by the limit lock block 4 and the locking block 5. Since the limit lock block 4 clamps both sides of the locking block 5 at the same time and the contact surface is large, it is not easy to cause major damage to the surface of the guide rail 1, thereby achieving the technical purpose of making the locking operation convenient and the locking reliable.

[0021] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
