Description

Technical Field

[0001] The utility model relates to the technical field of wire locking machines, in particular to a positioning device for wire locking equipment. Background Art

[0002] The thread locking machine, also known as the automatic screw locking machine, is a device that uses various electric and pneumatic components to realize the automatic conveying, tightening, and detection of screws. It can simplify the screw tightening process, reduce the number of labor and the adverse factors caused by manual misoperation. It is a typical non-standard automation equipment. The automatic screw locking machine is mainly composed of an automatic nail feeding machine, a locking mechanism, a power supply electrical box, a positioning system and other parts. The automatic nail feeding machine is responsible for the screening, arrangement, detection, material distribution, and conveying of screws. The existing thread locking equipment only limits the two sides of the product when clamping the product. Although it can effectively reduce the possibility of lateral sliding of the product, the workbench may vibrate during the screw locking process, causing the product to move longitudinally, resulting in a slight deviation between the screw and the screw hole of the product, causing a certain error, thereby causing a certain degree of damage to the product.

[0003] For example, an automatic screw locking machine disclosed in a Chinese patent document (Announcement No.: CN218016988U) limits the position of the product by placing a slot in conjunction with a fixed baffle, and locks the fixed baffle through a locking member to achieve precise fixation of the product, thereby reducing the situation where the screw locking deviation is caused by product displacement.

[0004] However, it can only position products with the same width as the placement slot, and greatly limits products that require screw locking, resulting in a lower scope of application. In addition, the clamping plate and the upper end of the product are sliding limiters, which not only easily cause wear on the product, but the gap between the clamping plate and the upper end of the product is also prone to vibration, causing the product to jump up and down, resulting in screw locking deviation.

DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0024] Reference Figure 1-4 A positioning device for a wire locking device comprises a workbench body 1, the inner bottom wall of the workbench body 1 is fixedly connected with guide rods 2 which are symmetrically distributed, the outer surfaces of the two guide rods 2 are movably sleeved with lifting plates 3, a servo electric cylinder 4 is fixedly installed on the inner bottom wall of the workbench body 1, one end of the piston rod of the servo electric cylinder 4 is fixedly connected to the lower surface of the lifting plate 3, the upper surface of the workbench body 1 is fixedly connected with a symmetrically distributed limiting tube 5, and the outer surface of the limiting tube 5 is provided with an arc-shaped limiting groove 6;

[0025] The inner wall of the position-limiting tube 5 is provided with an auxiliary clamping device, and the auxiliary clamping device comprises a lifting and rotating rod 7 , and the outer surface of the lifting and rotating rod 7 is movably sleeved with the inner wall of the position-limiting tube 5 .

[0026] Furthermore, one end of the lifting and rotating rod 7 is fixedly connected to a pressure plate 71, the lower surface of the pressure plate 71 is fixedly connected to a first anti-slip rubber pad 72, and the outer surface of the lifting and rotating rod 7 is fixedly connected to a limiting slide rod 73. Through the rotation of the lifting and rotating rod 7 during lifting, the pressure plate 71 is placed on the outside when not clamping the product, thereby facilitating the placement of the product.

[0027] Furthermore, the outer surface of the limit slide bar 73 is slidably connected to the inner wall of the arc-shaped limit groove 6, and the other end of the lifting and rotating rod 7 passes through and extends to the interior of the workbench body 1. The outer surfaces of the other ends of the two lifting and rotating rods 7 are installed on the upper surface of the lifting plate 3 through bearings. The upper surface of the workbench body 1 is fixedly connected with a placing table 74. The limit slide bar 73 is used in conjunction with the arc-shaped limit groove 6 to enable the lifting and rotating rod 7 to rotate during the lifting and moving.

[0028] Furthermore, the upper surface of the placement table 74 is provided with symmetrically distributed travel grooves 75, and the inner walls on both sides of the placement table 74 are equipped with bidirectional screw rods 76 through bearings, and the outer surface of the bidirectional screw rods 76 is fixedly sleeved with a worm gear 77, and the inner bottom wall of the placement table 74 is fixedly installed with a servo motor 78. The travel grooves 75 play a role in guiding and limiting the moving stroke.

[0029] Furthermore, a worm 79 is fixedly mounted on the output shaft of the servo motor 78 through a coupling, and the outer surface of the worm 79 meshes with the tooth surface of the worm wheel 77. The outer surface of the bidirectional lead screw 76 is threadedly connected with symmetrically distributed thread blocks 710. The self-locking characteristics of the worm 79 and the worm wheel 77 prevent the bidirectional lead screw 76 from rotating under force.

[0030] Furthermore, a travel block 711 is fixedly connected to the upper surface of the threaded block 710, one end of the travel block 711 passes through the travel groove 75 and extends to the upper surface of the placement table 74, one end of the travel block 711 is fixedly connected to a clamping block 712, and the travel block 711 is used in conjunction with the travel groove 75 to position and move the threaded block 710.

[0031] Furthermore, the opposite surfaces of the two clamping blocks 712 are respectively fixedly connected with the second anti-skid rubber pads 713, and the upper surface of the workbench body 1 is fixedly connected with the symmetrically distributed electric slide rails 714. The outer surface of the electric slide rail 714 is slidably sleeved with sliding blocks 715. The upper surfaces of the two sliding blocks 715 are fixedly installed with the thread locking machine body 716. The second anti-skid rubber pads 713 enable the clamping blocks 712 to softly clamp the two sides of the product to avoid damage to the product.

[0032] By setting up an auxiliary clamping device, after the two sides of the product are initially clamped and fixed, the top of the product is auxiliary pressed and limited by the pressure plate 71, thereby avoiding vibration of the product during the screw locking process and improving the screw locking quality of the product. In addition, the use of automated clamping and positioning is convenient to operate and improves work efficiency.

[0033] Working principle: Step 1, place the product on the placement table 74, and then start the servo motor 78, the servo motor 78 drives the worm 79 to rotate clockwise, the rotation of the worm 79 drives the bidirectional screw 76 to rotate through the meshing worm wheel 77, the rotation of the bidirectional screw 76 drives the two threaded blocks 710 to move relative to each other through the travel groove 75 and the travel block 711, thereby driving the two clamping blocks 712 to move relative to each other to perform preliminary clamping and positioning on both sides of the product, and the second anti-slip rubber pad 713 protects both sides of the product;

[0034] The second step is to start the servo electric cylinder 4 piston rod to retract. The retraction of the servo electric cylinder 4 piston rod drives the lifting plate 3 to move downward. The downward movement of the lifting plate 3 drives the lifting rotating rod 7 to move downward. The downward movement of the lifting rotating rod 7 is rotated and descended through the cooperation of the limit slide bar 73 and the arc limit groove 6, thereby driving the pressure plate 71 to rotate and move downward. When the pressure plate 71 rotates and descends until the first anti-slip rubber pad 72 contacts the upper end of the product, the servo electric cylinder 4 piston rod stops retracting. At this time, the pressure plate 71 further clamps and limits the upper end of the product through the cooperation of the placement table 74. At this time, the thread locking machine body 716 can be started to screw the product. By double clamping and limiting the product, vibration and displacement of the product when the screws are locked are avoided.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
