[0027] 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.
[0028] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: an anti-deformation fixing fixture, comprising a base plate 1, a fixing assembly 2 is fixedly connected to both sides of the top of the base plate 1, and an elastic assembly 3 is fixedly connected to the outer side of the fixing assembly 2; the fixing assembly 2 comprises a positioning column 21, the bottom end of the positioning column 21 is fixedly connected to both sides of the top of the base plate 1, the outer side of the positioning column 21 is rotatably connected to a rotating column 22, one end of the rotating column 22 is fixedly connected to a clamping block 23, an elastic pad 24 is fixedly connected to the inner wall of the clamping block 23, and one end of the elastic pad 24 away from the clamping block 23 is fixedly connected to a plurality of limiting columns 25, and the role of the positioning column 21 is to ensure the stability and accurate positioning of the entire structure. Their bottom ends are fixedly connected to both sides of the top of the base plate 1, so that the firm connection between the entire assembly and the base plate 1 can be ensured, and the design of the rotating column 22 enables the rotating column 22 to rotate around the positioning column 21, thereby realizing flexible control of the rotating column 22. This design of rotation connection provides convenience for the subsequent adjustment of the clamping block 23, and the role of the clamping block 23 is to fix or clamp other objects. By connecting with the rotating column 22, the clamping block 23 can be adjusted at different angles or positions, so as to achieve precise control of the clamped object. The design of the elastic pad 24 provides an elastic support effect. Compared with traditional clamping, it can reduce damage to the surface of the clamped object. The function of the limit column 25 is to limit the movement range of the clamped object to ensure that it maintains a stable position during the clamping process. By connecting with the elastic pad 24, the limit column 25 can provide an elastic support effect when it contacts the workpiece 8.
[0029] Furthermore, Figure 1As shown: the top of the bottom plate 1 is fixedly connected with a cylinder 4, the driving end of the cylinder 4 is fixedly connected with a push rod 5, the outer side of the push rod 5 is fixedly connected with a support plate 6, the end of the push rod 5 away from the support plate 6 is fixedly connected with a push plate 7, and a workpiece 8 is arranged at the top of the bottom plate 1. The cylinder 4 plays the role of providing power, which can apply pressure to the push rod 5 or push the push rod 5 to extend and retract. The function of the support plate 6 is to provide stable support. It can help disperse the force applied by the push rod 5 and prevent instability or damage caused by a single point of force. The push plate 7 is a moving device for the workpiece 8 on the bottom plate 1. Through the connection with the push rod 5, the push plate 7 can move with the extension and retraction of the push rod 5. When it contacts the workpiece 8, the workpiece 8 can be pushed or pulled.
[0030] Furthermore, Figure 2 - Figure 3 As shown in the figure: the end of the push plate 7 away from the push rod 5 is movably connected to one side of the workpiece 8, and the outer side of the workpiece 8 is movably connected to the outer side of the limit column 25, so that the push plate 7 can move along the surface of the workpiece 8. Through the connection with the workpiece 8, the push plate 7 can push the workpiece 8, and the limit column 25 is used to limit the movement range of the workpiece 8 to prevent it from exceeding the predetermined position or trajectory. This connection method ensures that the workpiece 8 can be fixed in the specified area under the action of the push plate 7.
[0031] In order to solve the problem that the clamping parts move to both sides after clamping to facilitate the next clamping, Figure 1 , Figure 3 and Figure 4 As shown: the elastic component 3 includes a connecting block 31, one end of the connecting block 31 is fixedly connected to the side of the rotating column 22 away from the clamping block 23, the inner wall of the connecting block 31 is fixedly connected to the sliding column 32, the adjacent sides of the two sliding columns 32 are fixedly connected to the telescopic columns 33, the outer side of the telescopic columns 33 is sleeved with a spring 34, one end of the spring 34 is fixedly connected to the sliding column 32, and the other end of the spring 34 is fixedly connected to both sides of the positioning block 35, the end of the telescopic column 33 away from the sliding column 32 is fixedly connected to the positioning block 35, and the connecting block 31 can move with the rotation of the rotating column 22 The function of the sliding column 32 is to provide sliding support inside the connecting block 31 so as to realize the relative movement of the connecting block 31, thereby sliding on the bottom plate 1 and maintaining a fixed moving route. The function of the telescopic column is to provide a stable support point when the sliding column 32 moves to adapt to different working requirements. The existence of the spring 34 can provide a certain elastic support so that the spring 34 can achieve a rebound effect when it is not under pressure. At the same time, the function of the positioning block 35 is to ensure that the spring 34 and the telescopic column 33 maintain a stable position during the working process, thereby ensuring the stability of the elastic component 3.
[0032] Working principle:
[0033] like Figure 1 - Figure 4 As shown:
[0034] When in use: First, the operator starts the cylinder 4, and the cylinder 4 pushes the push rod 5 to extend and retract. Then, the action of the push rod 5 is transmitted through the support plate 6 to ensure uniform distribution of force and avoid stability problems caused by concentrated force. The push plate 7 connected to it can be driven to move by the extension and retraction of the push rod 5. Thus, the push plate 7 slides along the surface of the workpiece 8 on the bottom plate 1 to push the workpiece 8. The precise operation of the workpiece 8 can be achieved. At the same time, when the workpiece 8 contacts the limit column 25, the rotating column 22 can rotate around the positioning column 21, and the clamping block 23 is connected to the rotating column 22 and can be adjusted at different angles or positions, thereby achieving precise control of the clamped object. The elastic pad 24 provides elastic support inside the clamping block 23, reducing damage to the surface of the clamped object. At this time, the design of the elastic component 3 realizes elasticity and position adjustment through the cooperation of the sliding column 32 and the telescopic column 33. The connecting block 31 moves with the rotation of the rotating column 22, and the sliding column 32 provides sliding support in the connecting block 31. The telescopic column 33 is equipped with a spring 34, so that when there is no external force compression, the spring 34 can automatically rebound to maintain the original state of the fixing component 2, which is convenient for the next clamping step.
