Description

Technical Field

[0001] The invention relates to the technical field of engine support bracket production, and in particular to a hydraulic clamping device for an engine support bracket. Background Art

[0002] The engine support bracket is an important component that connects the engine to the vehicle body and determines the stability of the engine installation. The engines of the same model with different displacements have different volumes, and the sizes of the support brackets vary to a certain extent. Most of the existing support bracket processing methods use three-axis machine tools for processing, and fixtures are required to fix and position the engine support bracket during processing.

[0003] When the engine support bracket is clamped on the fixture, since the shapes and sizes of the engine support bracket are all different, the commonly used fixture usually only clamps the engine support bracket with a flat surface. During the clamping process, the irregular parts of the engine support bracket surface cannot be fully clamped, resulting in only a few smaller surface contacts on the surface of the engine support bracket, affecting its clamping stability effect, resulting in the engine support bracket being prone to sliding during the subsequent processing of the engine support bracket, affecting its processing quality. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a hydraulic clamping device for an engine support bracket.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A hydraulic clamping device for an engine support bracket, comprising:

[0007] A base, wherein two L-shaped plates are fixedly connected to the upper end of the base;

[0008] The clamping mechanism includes a hydraulic cylinder fixedly connected to the upper end of the L-shaped plate, the movable end of the hydraulic cylinder is fixedly connected to the fixed plate, the side walls on both sides of the fixed plate are fixedly connected to connecting plates, the lower end of one of the connecting plates is elastically connected to the first pressure plate through a first spring, and the lower end of the other connecting plate is elastically connected to the second pressure plate through a first spring, the upper ends of the first and second pressure plates are fixedly connected to slide plates, the side walls of the slide plates are slidably connected to the side walls of the L-shaped plate, and a balancing mechanism is provided in the fixed plate.

[0009] Preferably, the balancing mechanism includes a first groove and a second groove opened at the lower end of the fixed plate, the inner walls of the first groove and the second groove are sealed and slidably connected with a slider, the upper end of the first pressure plate is fixedly connected to a first vertical rod, the upper end of the first vertical rod is fixedly connected to the lower end of the slider located in the first groove, the upper end of the second pressure plate is fixedly connected to a second vertical rod, the upper end of the second vertical rod is fixedly connected to the lower end of the slider located in the second groove, the first groove and the second groove are connected above the inner walls through a connecting pipe, and hydraulic oil is provided in the first groove and the second groove.

[0010] Preferably, the L-shaped plate side wall has multiple second springs elastically connected to a clamp, the side wall of the clamp close to the second spring is fixedly connected to a first rod, the side wall of the first rod is slidably connected to the side wall of the L-shaped plate, and a moving mechanism for driving the first rod to move is provided on the fixed plate.

[0011] Preferably, the moving mechanism includes a second rod fixedly connected to the upper side wall of the fixed plate, the side wall of the slide plate located on the first pressure plate is provided with a first through groove, the side wall of the L-shaped plate is provided with a second through groove, and the side wall of the second rod passes through the first through groove and the second through groove.

[0012] Preferably, the side wall of the second rod away from the fixed plate is fixedly connected to the first wedge plate, the side wall of the first rod away from the clamping plate is fixedly connected to the second wedge plate, and the first wedge plate and the second wedge plate cooperate with each other at the side walls close to each other.

[0013] The present invention has the following beneficial effects:

[0014] 1. A clamping mechanism is set up. When the lower end of the first pressing plate first contacts the upper end of the engine support bracket, as the fixed plate continues to move downward, the second vertical rod drives the second pressing plate to move downward and contacts the lower position of the upper end of the engine support bracket. In this way, the first pressing plate and the second pressing plate can press different positions of the upper end of the engine support bracket to achieve stable pressing of the irregular engine support bracket, avoiding the clamping of the engine support bracket surface in the prior art where only a few smaller surfaces are contacted, affecting the clamping stability effect, resulting in the engine support bracket being prone to sliding during the subsequent processing of the engine support bracket, affecting its processing quality.

[0015] 2. A clamping plate and a moving mechanism are set. When the fixed plate moves downward, the second rod drives the first wedge plate to move downward. When the first wedge plate moves downward and contacts the second wedge plate, the second wedge plate will drive the clamping plate through the second rod to move toward the direction close to the engine support bracket, thereby clamping the engine support bracket to avoid changes in the position of the engine support bracket during the subsequent pressing process of the engine support bracket.

DETAILED DESCRIPTION

[0020] 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 the embodiments.

[0021] Reference Figure 1-Figure 3 A hydraulic clamping device for an engine support bracket comprises a base 1, and two L-shaped plates 2 are fixedly connected to the upper end of the base 1.

[0022] The clamping mechanism includes a hydraulic cylinder 3 fixedly connected to the upper end of the L-shaped plate 2, the movable end of the hydraulic cylinder 3 is fixedly connected to the fixed plate 4, the side walls on both sides of the fixed plate 4 are fixedly connected to the connecting plates 5, the lower end of one of the connecting plates 5 is elastically connected to the first pressure plate 7 through the first spring 6, the lower end of the other connecting plate 5 is elastically connected to the second pressure plate 8 through the first spring 6, the upper ends of the first pressure plate 7 and the second pressure plate 8 are fixedly connected to the slide plate 15, and the side wall of the slide plate 15 is slidably connected to the side wall of the L-shaped plate 2.

[0023] A balancing mechanism is provided in the fixed plate 4, and the balancing mechanism includes a first groove 9 and a second groove 10 opened at the lower end of the fixed plate 4, the inner walls of the first groove 9 and the second groove 10 are sealed and slidably connected with a slider 11, the upper end of the first pressure plate 7 is fixedly connected to a first vertical rod 12, the upper end of the first vertical rod 12 is fixedly connected to the lower end of the slider 11 located in the first groove 9, the upper end of the second pressure plate 8 is fixedly connected to a second vertical rod 13, the upper end of the second vertical rod 13 is fixedly connected to the lower end of the slider 11 located in the second groove 10, the upper inner walls of the first groove 9 and the second groove 10 are connected through a connecting pipe 14, and hydraulic oil is provided in the first groove 9 and the second groove 10.

[0024] When the engine support bracket is placed on the base 1, the hydraulic cylinder 3 is adjusted to extend, and the first pressing plate 7 and the second pressing plate 8 are driven to move downward through the fixing plate 4. When the first pressing plate 7 or the second pressing plate 8 first contacts the upper end of the engine support bracket (due to the irregularity of the upper end of the engine support bracket), the first pressing plate 7 or the second pressing plate 8 will undergo different changes. The following is an example of the first pressing plate 7 first contacting the upper end of the engine support bracket:

[0025] When the lower end of the first pressure plate 7 first contacts the upper end of the engine support bracket, as the fixing plate 4 continues to move downward, the first pressure plate 7 moves upward under the pressure of the engine support bracket, and the first vertical rod 12 squeezes the slider 11 in the first groove 9, and squeezes the hydraulic oil in the first groove 9 into the second groove 10 through the connecting pipe 14, so that the slider 11 in the second groove 10 moves downward, and then the second vertical rod 13 drives the second pressure plate 8 to move downward and contact the lower position of the upper end of the engine support bracket. In this way, the first pressure plate 7 and the second pressure plate 8 can press different positions of the upper end of the engine support bracket to achieve stable pressing of the irregular engine support bracket, avoiding the clamping of the engine support bracket surface in the prior art with only a few smaller surface contacts, affecting its clamping stability effect, resulting in the engine support bracket being prone to sliding during the subsequent processing of the engine support bracket, affecting its processing quality.

[0026] The side wall of the L-shaped plate 2 is elastically connected to a clamping plate 17 by multiple second springs 18. The side wall of the clamping plate 17 close to the second springs 18 is fixedly connected to a first rod 16. The side wall of the first rod 16 is slidably connected to the side wall of the L-shaped plate 2. A moving mechanism for driving the first rod 16 to move is provided on the fixed plate 4.

[0027] The moving mechanism includes a second rod 19 fixedly connected to the upper side wall of the fixed plate 4, a first through groove 20 is opened on the side wall of the slide plate 15 located on the first pressure plate 7, a second through groove 21 is opened on the side wall of the L-shaped plate 2, and the side wall of the second rod 19 passes through the first through groove 20 and the second through groove 21.

[0028] The side wall of the second rod 19 away from the fixing plate 4 is fixedly connected with the first wedge plate 22, and the side wall of the first rod 16 away from the clamping plate 17 is fixedly connected with the second wedge plate 23. The first wedge plate 22 and the second wedge plate 23 cooperate with each other at their side walls close to each other.

[0029] When the fixing plate 4 moves downward, the second rod 19 drives the first wedge plate 22 to move downward. When the first wedge plate 22 moves downward and contacts the second wedge plate 23, the second wedge plate 23 drives the clamping plate 17 to move toward the engine support bracket through the second rod 19, thereby clamping the engine support bracket. Figure 1As shown, only part of the side walls of the first wedge plate 22 and the second wedge plate 23 are inclined, that is, when the side walls of the first wedge plate 22 and the second wedge plate 23 are in contact with each other in the vertical direction, the clamping of the engine support bracket is completed. When the first wedge plate 22 continues to move downward, the position of the clamping plate 17 does not change, thereby avoiding the position change of the engine support bracket during the subsequent clamping process of the engine support bracket.

[0030] When the engine support bracket is pressed, the engine support bracket is first placed on the upper end of the base 1, and then the two hydraulic cylinders 3 are adjusted to extend. At this time, the fixed plate 4 drives the first pressing plate 7 and the second pressing plate 8 to move downward, and at this time, the fixed plate 4 drives the first wedge plate 22 to move downward through the second rod 19. When the first wedge plate 22 moves downward and contacts the second wedge plate 23, the second wedge plate 23 drives the clamping plate 17 to move toward the engine support bracket through the second rod 19, and the engine support bracket is clamped. Figure 1 As shown, only part of the side walls of the first wedge plate 22 and the second wedge plate 23 are inclined, that is, when the side walls of the first wedge plate 22 and the second wedge plate 23 are in contact with each other in the vertical direction, the clamping of the engine support bracket is completed, and when the first wedge plate 22 continues to move downward, the position of the clamping plate 17 does not change;

[0031] When the first pressing plate 7 or the second pressing plate 8 first contacts the upper end of the engine support bracket (due to the irregularity of the upper end of the engine support bracket), the first pressing plate 7 or the second pressing plate 8 will undergo different changes. The following is an example of the first pressing plate 7 first contacting the upper end of the engine support bracket:

[0032] When the lower end of the first pressure plate 7 first contacts the upper end of the engine support bracket, as the fixing plate 4 continues to move downward, the first pressure plate 7 moves upward under the pressure of the engine support bracket, and the first vertical rod 12 squeezes the slider 11 in the first groove 9, and squeezes the hydraulic oil in the first groove 9 into the second groove 10 through the connecting pipe 14, so that the slider 11 in the second groove 10 moves downward, and then the second vertical rod 13 drives the second pressure plate 8 to move downward and contact the lower position of the upper end of the engine support bracket. In this way, the first pressure plate 7 and the second pressure plate 8 can press different positions of the upper end of the engine support bracket to achieve stable pressing of the irregular engine support bracket, avoiding the clamping of the engine support bracket surface in the prior art with only a few smaller surface contacts, affecting its clamping stability effect, resulting in the engine support bracket being prone to sliding during the subsequent processing of the engine support bracket, affecting its processing quality.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
