DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-2The utility model discloses a displacement pressing mechanism, including a bracket 1, wherein two guide plates 2 are relatively arranged inside the bracket 1, and guide wheels 201 are movably arranged at both ends of the guide plates 2. Guide grooves 102 which are movably sleeved with the guide wheels 201 at both sides of the guide plates 2 are arranged on both sides of the bracket 1. A plurality of pressure rods 202 are arranged inside the guide plates 2, and one end of the pressure rod 202 extends to one side of the guide plates 2 and is provided with a clamp 203. The other side of the guide plates 2 is connected to a cylinder 208 through a guide rod 207. A compression spring 204 is sleeved on the pressure rod 202. After the clamp 203 contacts the product and presses it, the multiple compression springs 204 press each product respectively to prevent the object from not being pressed tightly, and to prevent the overall failure to press the product and the failure of the workpiece in the event of a sudden power outage or gas failure, thereby increasing the secondary protection of power failure and gas failure. The guide plates 2 are displaced by lifting and moving horizontally at the same time, which is convenient for workers to take materials, and has a simple and compact structure.

[0020] Specifically, the guide rail groove 102 is arc-shaped, at least two slide rails 205 are provided on one side of the guide plate 2, a slider 206 is slidably sleeved on one side of the slide rail 205, and the guide rod 207 is provided on the side of the slider 206 away from the slide rail 205, see Figure 1 The arc-shaped guide groove 102 can limit the movement trajectory of the guide plate 2 through the guide wheel 201. When the cylinder 208 pulls the guide plate 2 through the guide rod 207, the guide wheels 201 at both ends of the guide plate 2 will slide along the guide groove 102. Figure 1 The guide wheel 201 drives the guide plate 2 to move backward and upward, and the slide rail 205 cooperates with the slider 206 to ensure the stability of the guide plate 2 when it moves, so that the guide plate 2 always remains in a horizontal state. The guide plate 2 as a whole produces horizontal and height displacements, thereby greatly reducing the dislocation space. If a straight up and down method is adopted, a very high stroke is required for workers to grab it conveniently; if a translation method is adopted, the workpiece will be driven to move at the moment of pressing down; therefore, it must be pressed vertically at the end, and then it needs to be dislocated while rising and moving horizontally to facilitate workers to pick up materials.

[0021] Specifically, a thread is engraved on one end of the pressure rod 202 away from the clamp 203, and a sliding sleeve is provided inside the guide plate 2 to be sleeved with the threaded part of the pressure rod 202. The sliding sleeve is movably nested inside one side of the guide plate 2. The position between the pressure rod 202 and the sliding sleeve is adjusted by rotating the pressure rod 202. The thread can adjust the length of the pressure rod 202 extending out of the other side of the guide plate 2, and can also adjust the preload force of the compression spring 204.

[0022] Specifically, a product fixture 101 located between two guide plates 2 is provided inside the bracket 1 for placing the product to be clamped, and the IGBT module to be compressed is placed inside the product fixture 101 .

[0023] Specifically, the bracket 1 includes two side plates 103 and two end plates 104 respectively disposed between the two ends of the two side plates 103. The end plates 104 are provided with ball linear bearings 105 inside. One end of the guide rod 207 passes through the ball linear bearings 105 and is connected to the output end of the cylinder 208. Figure 1 , start the cylinder 208, the cylinder 208 pushes the guide rod 207 to slide inside the ball linear bearing 105, and at the same time the guide rod 207 pushes the guide plate 2 through the slider 206 and the slide rail 205. After the clamp 203 presses the IGBT module, multiple compression springs 204 press each IGBT module respectively to prevent the object from not being pressed tightly, and to prevent the overall product from not being pressed tightly in the event of a sudden power outage or gas failure, thereby causing the workpiece to fail, and to increase the secondary protection of power failure or gas failure.

[0024] Specifically, the surface of the guide rod 207 is sleeved with a spring located between the end plate 104 and the slider 206. The setting of the spring makes the reset process of the guide rod 207 more flexible, and cooperates with the ball linear bearing 105 to enhance the smoothness of the active contact of the components and prevent the overall deviation due to inadequate coordination of the mechanical mechanism.

[0025] To sum up, in this displacement clamping mechanism, after the clamp 203 contacts and presses the product, multiple compression springs 204 press each product separately to prevent the object from not being pressed tightly, and to prevent the overall failure to press the product and the workpiece failure in the event of a sudden power outage or gas failure, thereby increasing the secondary protection against power outage and gas failure. The guide plate 2 is displaced by rising and moving horizontally to facilitate workers to take materials. The structure is simple and compact, and has broad application prospects.
