[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Reference Figure 1-4The utility model provides an embodiment: a positioning fixture with a rebound structure, including a containing plate 1, a groove 3 is opened in the middle of the upper end surface of the containing plate 1, and reset grooves 5 are opened in the middle of both sides of the groove 3, and reset components 6 are fixedly arranged inside the two reset grooves 5, and a base 8 is fixedly arranged on the containing plate 1, and fixing grooves 10 are opened on both sides of the lower end surface of the base 8, and fixing components 12 are fixedly arranged inside the two fixing grooves 10. By setting the groove 3 opened at the upper end of the containing plate 1 and the reset grooves 5 opened on both sides of the groove 3, the reset components 6 inside the reset groove 5 can position and clamp the products of different shapes and sizes, and by setting the fixing grooves 10 opened on both sides of the lower end surface of the base 8, the fixing components 12 inside the fixing grooves 10 can fix the base 8 on the placement surface to prevent the product from shaking during the clamping process.
[0035] The two reset components 6 include four slide grooves 604, four sliders 607, two hydraulic rods 605 and four limit plates 601. A movable plate 608 is fixedly arranged between the two hydraulic rods 605. A connecting rod 603 is fixedly arranged on the opposite side of the two movable plates 608. A latex pad 602 is fixedly arranged between the two connecting rods 603. The two hydraulic rods 605 are fixedly sleeved with a first reset spring 606. The movable plate 608 between the hydraulic rods 605 in the reset component 6 is connected to the connecting rod 603 between the movable plates 608. When the product is placed in the positioning clamp, the latex pad 602 is squeezed by the product and changes with the shape of the product. The connecting plate drives the movable plate 608 to squeeze the hydraulic rod 605, so that the first reset spring 606 around the hydraulic rod 605 produces a reset effect, so that the latex pad 602 can rebound, so that the product is more stable when clamped, and products of different sizes and shapes can be positioned and clamped.
[0036] The fixing assembly 12 includes an electric telescopic rod 1201 and two limiting rods 1203. A supporting plate 1204 is fixedly provided at the lower end of the electric telescopic rod 1201. A suction cup 1205 is fixedly provided at the middle of the lower end surface of the supporting plate 1204. The two limiting rods 1203 are fixedly sleeved with a second return spring 1202 around their upper parts. The electric telescopic rod 1201 arranged in the fixing assembly 12 drives the supporting plate 1204 to descend, so that the suction cup 1205 at the lower end of the supporting plate 1204 adsorbs the placement surface, and the two sides of the supporting plate 1204 slide around the limiting rod 1203, so that the second return spring 1202 around the limiting rod 1203 squeezes the supporting plate 1204, so that the placement surface is more stable when being adsorbed and fixed, and the product is prevented from shaking when it is clamped and processed.
[0037] The electric telescopic rod 1201 arranged in the fixing component 12 drives the carrying plate 1204 to descend, so that the suction cup 1205 at the lower end of the carrying plate 1204 adsorbs the placement surface, and the two sides of the carrying plate 1204 slide around the limiting rod 1203, so that the second return spring 1202 around the limiting rod 1203 squeezes the carrying plate 1204, making it more stable when adsorbing and fixing the placement surface, and preventing the product from shaking when it is clamped and processed.
[0038] The four slide grooves 604 are respectively arranged in pairs on the opposite sides of the four limit plates 601, and the four sliders 607 are respectively fixed at the front and rear ends of the two movable plates 608. The limit plates 601 arranged in pairs on the slide grooves 604 can facilitate the limit processing of the connecting rods 603 by the limit plates 601 arranged in pairs on the slide grooves 604. The sliders 607 are respectively fixed at the front and rear ends of the two movable plates 608, so that the movable plates 608 can drive the sliders 607 to slide in the slide grooves 604 when they move. The four sliders 607 are respectively slidably arranged in the four slide grooves 604. The opposite sides of the two latex pads 602 are arc-shaped. When the sliders 607 slide in the slide grooves 604, the movable plates 608 can be prevented from tilting when they move. The arc-shaped latex pads 602 are convenient for squeezing the products into between the latex pads 602 when putting them in, so that the latex pads 602 can fit and clamp the shape of the products, and the latex pads 602 can change their shapes to fully clamp and position the products.
[0039] A handle 2 is fixedly provided in the middle of both sides of the accommodating plate 1, and a controller 7 is embedded in the middle of the front end surface of the accommodating plate 1. The handles 2 arranged on both sides of the accommodating plate 1 are used to facilitate the movement of the accommodating plate 1, and the controller 7 embedded in the middle of the front end surface of the accommodating plate 1 is used to facilitate the control of the electric telescopic rod 1201. A accommodating groove 4 is provided in the middle of the inner bottom surface of the groove 3, and an anti-skid pad 9 is fixedly provided on the inner bottom surface of the accommodating groove 4. By providing the accommodating groove 4 in the middle of the inner bottom surface of the groove 3, the anti-skid pad 9 on the inner bottom surface of the accommodating groove 4 makes it convenient to prevent the product from shaking when clamping, thereby preventing movement of the product during processing and causing processing errors.
[0040] The two sides of the carrying plate 1204 are respectively slidably mounted on the two limit rods 1203, and the two sides of the carrying plate 1204 are fixed to the second return spring 1202 at the top. The carrying plate 1204 slides around the limit rod 1203 on both sides of the carrying plate 1204 and is fixed to the second return spring 1202 around the limit rod 1203, so that the carrying plate 1204 is squeezed by the second return spring 1202 when moving, and a rubber plate 11 is fixedly arranged at the lower end of the base 8. The rubber plate 11 fixedly arranged at the lower end of the base 8 makes the base 8 more stable and prevents sliding when being placed, and the squeezing of the second return spring 1202 can make the suction cup 1205 more stable when adsorbing the placement surface.
[0041] Working principle: first, place the base 8 on the placement surface, and use the fixing components 12 in the fixing grooves 10 opened on both sides of the lower end surface of the base 8 to stably adsorb the base 8 on the placement surface to prevent the base 8 from moving on the placement surface. By opening a groove 3 on the receiving plate 1 at the upper end of the base 8, the reset components 6 in the reset grooves 5 opened on both sides of the groove 3 can clamp the product placed in the receiving groove 4, and it is convenient to position and clamp products of different shapes and sizes, so that the product can be more fixed during processing.
