DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1-4 A clamping device for detecting a spur rack includes a processing table 1, a conveying member 2 for conveying the rack is provided on the top of the processing table 1, and a detection table 3 and a clamping member 4 are also provided on the top of the processing table 1 above the conveying member 2, the clamping member 4 is used to clamp and fix the rack, and the clamping member 4 also includes a driving member 5, and the driving member 5 is used to cooperate with the conveying member 2 to load the rack.

[0021] Specifically, the conveyor 2 includes a plurality of rollers 21 , and the top of the processing table 1 is located below the detection table 3 and is rotatably connected to the plurality of rollers 21 in parallel via mounting grooves 22 , and a conveyor belt 23 is sleeved between the rollers 21 .

[0022] Furthermore, the clamping member 4 includes a cylinder 41 fixedly installed on the top of the processing table 1, and fixed plates 42 are fixedly installed on both sides of the conveyor belt 23 in the mounting groove 22, a slide rail 43 is fixedly installed on the side of one of the fixed plates 42, and a gear 45 is rotatably connected to the top of the slide rail 43 through a rotating shaft 44, and a rack 46 is slidably connected to one side of the slide rail 43, and the rack 46 is meshed and slidably engaged with the gear 45 and fixedly connected to the shaft end of the cylinder 41.

[0023] It is worth mentioning that when the shaft end of the cylinder 41 is extended or retracted, it drives the rack 46 to drive the gear 45 to rotate, and the slide rail 43 facilitates the sliding of the rack 46 .

[0024] In more detail, a pair of the bottom of the fixed plates 42 are rotatably connected with a double-headed screw 47, a pulley 48 is fixedly installed between the double-headed screw 47 and one end of the rotating shaft 44, a transmission belt 481 is sleeved between the pair of pulleys 48, and a pair of guide grooves 221 communicating with the mounting grooves 22 are opened on the top of the processing table 1, a clamping plate 49 is slidably connected in the guide grooves 221, the bottom of a pair of the clamping plates 49 are threadedly connected to the two ends of the double-headed screw 47, and an elastic plate 491 is fixedly installed on the top thereof toward the side of the conveyor belt 23.

[0025] It should be noted that, because one end of the rotating shaft 44 is fixedly connected to the gear 45, driving the gear 45 can drive the rotating shaft 44 to rotate, and when the rotating shaft 44 rotates, it drives the pulley 48 to cooperate with the transmission belt 481 to drive the double-headed screw 47 to rotate;

[0026] The opposite directions of the threads at both ends of the double-ended screw 47 can simultaneously drive a pair of clamping plates 49 to move toward or away from each other, and the pair of clamping plates 49 can be used to clamp the rack to facilitate the detection of the detection platform 3;

[0027] It is worth mentioning that the clamping plate 49 is in a T-shaped structure, and the clamping plate 49 and the elastic plate 491 are in an L-shaped structure. On the one hand, the elastic effect of the elastic plate 491 can prevent the rack from being damaged by clamping, and on the other hand, the outward extension of the elastic plate 491 can prevent the clamping plate 49 and the conveyor belt 23 from being stuck.

[0028] In general, the driving member 5 includes a movable seat 51 slidably connected to the other side of the slide rail 43, a first connecting rod 52 is fixedly installed at one end of the rotating shaft 44, the end surface of the movable seat 51 is rotatably connected to the second connecting rod 53 and the movable rod 54, and the first connecting rod 52 and the second connecting rod 53 are rotatably connected.

[0029] It is worth mentioning that the rotation of the rotating shaft 44 drives the first connecting rod 52 to rotate, and the first connecting rod 52 drives the movable seat 51 to slide due to the rotation connection with the second connecting rod 53.

[0030] Finally, the axial ends of the pair of rollers 21 on the outermost sides are located in the mounting groove 22 and are sleeved with a synchronous belt 55, and a plurality of ridges 56 are arranged on the periphery of the synchronous belt 55, and the movable rod 54 can abut against the ridges 56 to drive the synchronous belt 55 to rotate, and the end faces of the fixed plate 42 and the movable seat 51 are fixedly installed with limiting rods 57, and a pair of limiting rods 57 are respectively used to clamp the first connecting rod 52 and the movable rod 54.

[0031] It should be noted that under the action of the pair of limit rods 57, the gear 45 rotates half a circle. This has the advantage that by driving the movable seat 51 to slide, the movable rod 54 abuts against the convex ridge 56, thereby driving the synchronous belt 55 to rotate.

[0032] Among them, because the conveyor belt 23 and the synchronous belt 55 are both mounted on the roller 21, the synchronous belt 55 is used to intermittently drive the conveyor belt 23 to rotate to load the rack, and because a pair of the clamping plates 49 and the synchronous belt 55 operate synchronously, the rack can be clamped and fixed immediately after feeding.

[0033] Working method: When working, multiple racks are placed on the conveyor belt 23 at a suitable interval. When the shaft end of the cylinder 41 is extended and retracted, the rack 46 drives the gear 45 to drive the shaft 44 to rotate. When the shaft 44 rotates, it drives the pulley 48 to cooperate with the transmission belt 481 to drive the double-headed screw 47 to rotate. At this time, a pair of clamping plates 49 are driven to move toward each other and the racks are clamped and fixed by the elastic plate 491;

[0034] Then, when the rotating shaft 44 rotates, the first connecting rod 52 is driven to rotate. The first connecting rod 52 drives the movable seat 51 to slide due to the rotation connection with the second connecting rod 53. Under the locking action of a pair of limit rods 57, the rotating shaft 44 rotates half a circle to drive the movable rod 54 to contact the convex ridge 56, so as to drive the synchronous belt 55 to drive the conveyor belt 23 to rotate.

[0035] Finally, under the action of the cylinder 41, a pair of clamping plates 49 and the conveyor belt 23 operate synchronously, which can achieve the function of clamping and fixing the rack immediately after feeding.

[0036] 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.
