Description

Technical Field

[0001] The present invention relates to the technical field of clamping for the production of the cross member, and particularly relates to a clamping device for the production of the cross member. Background Art

[0002] The cross member is an important component of the vehicle chassis. The cross member is located below the engine. It is mainly used to support the engine and connect the suspension components of the chassis. It is not a complete frame, but a part of the frame. It only supports the front and rear axles and the suspension, connecting the axles and the suspension to the vehicle frame. The cross member is also called the subframe. The subframe is not a complete vehicle frame, but only a bracket for supporting the front and rear axles and the suspension, enabling the axles and the suspension to be connected to the "main frame" through it, and is customarily called the "sub-frame". The function of the cross member is to block vibration and noise, reducing their direct entry into the passenger compartment, so it is mostly found in luxury cars and off-road vehicles, and some cars also install a sub-frame for the engine.

[0003] The types of cross members mainly include frame cross members, articulated cross members, wing beam subframes, full-frame subframes, cross members with a non-supporting body design, cross members with a supporting body design, front subframes and rear subframes. After the cross member is stamped and formed, it also needs to be surface-treated, such as cleaning, rust removal, degreasing, etc., to ensure the surface quality of the cross member. For defective cross members, welding repair is required, removing the oil stains, rust marks and dirt around the defect, and performing special treatment around the cracks of the cross member. During the above production and processing process, a clamping device is required to clamp and fix the cross member.

[0004] The existing clamping devices generally only clamp and fix cross members of the same size, with poor versatility. For cross members of different sizes and specifications, the corresponding clamping devices need to be replaced. If multiple types of cross members need to be produced and processed, multiple clamping devices need to be equipped. Summary of the Invention

[0005] Technical Problem to be Solved Aiming at the deficiencies of the prior art, the present invention provides a clamping device for the production of the cross member. By pumping air into and out of the internal chamber of the rubber layer through an air pump assembly, the movement states of multiple groups of steel balls in the chamber are changed. By clamping the to-be-clamped part of the cross member main body with multiple groups of steel balls, the clamping and fixing of the cross member main body are realized, and the wrapping of the special-shaped structure can be achieved, solving the technical problems mentioned in the background art.

[0006] Technical Solution To achieve the above object, the present invention is realized through the following technical solutions: A clamping device for the production of a cross member, comprising a bottom plate, on which a first clamping mechanism, a second clamping mechanism, a third clamping mechanism, a fourth clamping mechanism and a supporting mechanism are installed. The first clamping mechanism, the second clamping mechanism, the third clamping mechanism and the fourth clamping mechanism are independently arranged and cooperate together to perform four-point clamping and positioning on the cross member body. One clamping mechanism corresponds to one clamping point, and the position of the clamping component at the end of the corresponding clamping mechanism is adjusted according to the position of each clamping point. The first clamping mechanism, the second clamping mechanism, the third clamping mechanism and the fourth clamping mechanism all include a slide rail, a first electric cylinder and an air pump assembly. A slide seat is slidably arranged on the slide rail. The push rod of the first electric cylinder is fixedly connected to the slide seat. A second electric cylinder is installed on the slide seat. The push rod of the second electric cylinder is fixedly connected to a fixing frame. A first motor is installed on the fixing frame. The output shaft of the first motor is connected to the clamping component. The clamping component includes a base and a rubber layer. Multiple groups of steel balls are arranged in the rubber layer. An air nozzle is opened on the base. The air pump assembly is connected to the air nozzle of the base through a hose. The supporting mechanism is used to support the cross member body. The rubber layer of the clamping component has a certain elastic deformation ability. When the air pump assembly works, it can blow air or suck air to the clamping component through the hose. By pumping air and inflating the internal chamber of the rubber layer by the air pump assembly, the movement state of multiple groups of steel balls in the chamber is changed.

[0007] In a possible implementation manner, the first clamping mechanism, the second clamping mechanism, the third clamping mechanism and the fourth clamping mechanism are respectively located at the corners of the bottom plate, and the supporting mechanism is located at the middle position on the bottom plate. When clamping the cross member body, first place the cross member body on the supporting mechanism, lift the cross member body to a specified height position by the supporting mechanism, and then adjust the positions of the clamping mechanisms.

[0008] In a possible implementation manner, a first connecting plate is welded and fixed on the slide seat. One end of the push rod of the first electric cylinder is fixedly connected to the first connecting plate. When the first electric cylinder works, it drives the first connecting plate at its one end, and drives the slide seat to slide along the slide rail through the first connecting plate.

[0009] In a possible implementation manner, the second electric cylinder is fixedly connected to the slide seat through a second connecting plate. When the slide seat slides along the slide rail driven by the first electric cylinder, it drives the second connecting plate on its upper part to slide along the slide rail synchronously, and the second connecting plate drives the second electric cylinder to slide along the slide rail synchronously.

[0010] In a possible implementation manner, the clamping component includes a connecting rod. The output shaft of the first motor is fixedly connected to the connecting rod of the clamping component through a coupling. When the first motor works, it drives the connecting rod at its one end to rotate, and the connecting rod drives the clamping component to rotate synchronously. By controlling the number of rotation turns and the rotation direction of the first motor, the angle of the clamping component is adjusted.

[0011] In a possible implementation, a chamber is formed between the rubber layer and the base, and multiple groups of steel balls are located in the chamber. In the initial state, the air pressure inside the chamber of the rubber layer is balanced with the external atmospheric pressure, and the multiple groups of steel balls in the chamber are in a loose state. When the air pump assembly evacuates the chamber inside the rubber layer, the multiple groups of steel balls fit tightly together.

[0012] In a possible implementation, the air nozzle of the clamping assembly is in communication with the chamber of the clamping assembly, and the hose is in communication with the air nozzle of the clamping assembly. Gas can be filled into the chamber of the clamping assembly through the hose, and the gas inside the chamber of the clamping assembly can also be extracted through the hose.

[0013] In a possible implementation, the supporting mechanism includes a linear drive base, the linear drive base includes a slide table, a third electric cylinder is installed on the slide table, and one end of the push rod of the third electric cylinder is fixedly connected to a supporting table. When the third electric cylinder works, it can drive the supporting table to move axially to adjust the height position of the supporting table.

[0014] In a possible implementation, the linear drive base includes a second motor, the output shaft of the second motor is connected to a lead screw, and slide rods are arranged on both sides of the lead screw.

[0015] In a possible implementation, both the slide rod and the lead screw penetrate through the slide table, and the slide table is slidably connected to the slide rod. When the linear drive base works, it can drive the supporting table to move horizontally, and the supporting table can be moved into and out under the drive of the linear drive base.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention evacuates and inflates the chamber inside the rubber layer through the air pump assembly to change the movement state of multiple groups of steel balls in the chamber. When positioning and wrapping the part to be clamped of the front axle beam main body, the multiple groups of steel balls are in a loose state, adapting to the outer contour shape of the part to be clamped of the front axle beam main body and wrapping around the outside of the part to be clamped. Then, the redundant air inside the chamber of the rubber layer is extracted through the air pump assembly. Under the action of the external atmospheric pressure, the rubber layer undergoes corresponding elastic deformation, squeezing the multiple groups of steel balls. The multiple groups of steel balls in the chamber of the rubber layer fit tightly together and can no longer move randomly. By clamping the part to be clamped of the front axle beam main body with multiple groups of steel balls, the clamping and fixing of the front axle beam main body are realized, and the wrapping of a special-shaped structure can be achieved.

[0017] 2. The horizontal position, height position, and angle of the clamping assembly at the end of each clamping mechanism of the present invention can be adjusted separately under the drive of the first electric cylinder, the second electric cylinder, and the first motor, which is suitable for clamping and fixing the cross members of different sizes and specifications. One set of clamping devices can clamp multiple cross member bodies of different types. The position of the clamping assembly at the end of the corresponding clamping mechanism is adjusted according to the position of each clamping point, which has good versatility.

[0018] 3. When clamping the cross member body, the supporting table is driven by the linear drive base to move into the supporting position to support the cross member body. After the cross member body is clamped and fixed, the third electric cylinder drives the supporting table to move down a certain distance, and the linear drive base drives the supporting table to move horizontally out, without blocking the lower structure of the cross member body, which helps the smooth progress of the processing operation of the cross member body.

Detailed implementation mode

[0022] In an embodiment of the present application, a clamping device for cross member production is provided. By pumping air in and out of the internal chamber of the rubber layer through the air pump assembly, the movement states of multiple groups of steel balls in the chamber are changed. By clamping the to-be-clamped part of the cross member main body with multiple groups of steel balls, the clamping and fixing of the cross member main body are realized, and the wrapping of the special-shaped structure can be achieved, solving the technical problems mentioned in the background art.

[0023] The technical solution in the embodiment of the present application is to solve the problems in the above background art, and the general idea is as follows: Embodiment 1: Please refer to Figures 1-10 , the present invention provides a technical solution: a clamping device for cross member production, including a base plate 1, on which a first clamping mechanism 2, a second clamping mechanism 3, a third clamping mechanism 4, a fourth clamping mechanism 5 and a supporting mechanism 6 are installed. The first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4 and the fourth clamping mechanism 5 all include a slide rail 21, a first electric cylinder 22 and an air pump assembly 28. A slide block 23 is slidably arranged on the slide rail 21. The push rod of the first electric cylinder 22 is fixedly connected to the slide block 23. A second electric cylinder 24 is installed on the slide block 23. The push rod of the second electric cylinder 24 is fixedly connected to a fixing bracket 25. A first motor 26 is installed on the fixing bracket 25. The output shaft of the first motor 26 is connected to a clamping assembly 27. The clamping assembly 27 includes a base 271 and a rubber layer 272. Multiple groups of steel balls 273 are arranged in the rubber layer 272. An air nozzle 274 is opened on the base 271. The air pump assembly 28 is connected to the air nozzle 274 of the base 271 through a hose 29. The supporting mechanism 6 is used to support the cross member main body 7.

[0024] Among them, one corner position of the crossmember main body 7 is clamped by the first clamping mechanism 2, one corner position of the crossmember main body 7 is clamped by the second clamping mechanism 3, one corner position of the crossmember main body 7 is clamped by the third clamping mechanism 4, and one corner position of the crossmember main body 7 is clamped by the fourth clamping mechanism 5. The first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4, and the fourth clamping mechanism 5 are independently arranged and cooperate together to achieve comprehensive clamping and fixing of the crossmember main body 7.

[0025] The rubber layer 272 of the clamping assembly 27 has a certain elastic deformation ability. When the air pump assembly 28 works, it can blow air or suck air into the clamping assembly 27 through the hose 29. When the clamping assembly 27 is in the initial state, as Figure 7 shown, multiple groups of steel balls 273 are placed in the chamber of the rubber layer 272 and are in a loose state, and the positions of the multiple groups of steel balls 273 can change correspondingly with the external force.

[0026] When the clamping assembly 27 performs the clamping operation, as Figure 8 shown, the rubber layer 272 of the clamping assembly 27 first contacts the part to be clamped of the crossmember main body 7. The rubber layer 272 generates corresponding elastic deformation under the action of the external force. The positions of the multiple groups of steel balls 273 in the chamber of the rubber layer 272 move correspondingly under the action of the external force. The rubber layer 272 wraps around the outside of the part to be clamped of the crossmember main body 7. At this time, the air pump assembly 28 sucks air from the clamping assembly 27, extracting the excess air in the chamber of the rubber layer 272. Under the action of the external atmospheric pressure, the multiple groups of steel balls 273 in the chamber of the rubber layer 272 are closely attached together until the positions of the multiple groups of steel balls 273 can no longer move randomly. At this time, the multiple groups of steel balls 273 wrap around the outside of the part to be clamped of the crossmember main body 7, and the multiple groups of steel balls 273 bite the part to be clamped of the crossmember main body 7 to achieve the clamping of the crossmember main body 7. The first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4, and the fourth clamping mechanism 5 all clamp the part to be clamped of the crossmember main body 7 in the above manner. The crossmember main body 7 is comprehensively clamped by the four clamping mechanisms to ensure the stability of the crossmember main body 7.

[0027] The shape of the rubber layer 272 of the clamping assembly 27 and the positions of the multiple groups of steel balls 273 in the chamber of the rubber layer 272 can both adapt to the outer contour shape of the part to be clamped of the crossmember main body 7, can realize the wrapping of the special-shaped structure, and then realize the clamping of the special-shaped structure, which is suitable for the clamping of crossmembers of different sizes and specifications and has good versatility.

[0028] When the first electric cylinder 22 works, it can drive the slide block 23 at one end along the slide rail 21 to flexibly adjust the horizontal position of the end clamping assembly 27. When the second electric cylinder 24 works, it can drive the fixed frame 25 to move axially, and then drive the clamping assembly 27 at the end to flexibly adjust the height position of the clamping assembly 27. When the first motor 26 works, it can drive the clamping assembly 27 at one end to rotate to flexibly adjust the angle of the clamping assembly 27.

[0029] The first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4 and the fourth clamping mechanism 5 are independently arranged. The horizontal position, height position and angle of the end clamping assembly 27 of each group of clamping mechanisms can be adjusted separately. The main body 7 of the cross member is clamped and positioned at four points by the first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4 and the fourth clamping mechanism 5. One group of clamping mechanisms corresponds to one clamping point. The position of the end clamping assembly 27 of the corresponding clamping mechanism is adjusted according to the position of each clamping point. Even if the angles and height positions of the four fixing points of the main body 7 of the cross member are different, the comprehensive clamping and positioning of the main body 7 of the cross member can be realized, which is suitable for clamping cross members of different sizes and specifications. One group of clamping devices can clamp multiple groups of different main bodies 7 of the cross member.

[0030] In some examples, the first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4 and the fourth clamping mechanism 5 are respectively located at the corners of the bottom plate 1, and the supporting mechanism 6 is located at the middle position on the bottom plate 1.

[0031] When clamping the main body 7 of the cross member, first place the main body 7 of the cross member on the supporting mechanism 6, and then adjust the positions of the clamping mechanisms. The main body 7 of the cross member is clamped by the first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4 and the fourth clamping mechanism 5, without manual lifting.

[0032] In some examples, a first connecting plate 231 is welded and fixed on the slide block 23. One end of the push rod of the first electric cylinder 22 is fixedly connected to the first connecting plate 231. When the first electric cylinder 22 works, it drives the first connecting plate 231 at one end, and drives the slide block 23 to slide along the slide rail 21 through the first connecting plate 231.

[0033] In some examples, the second electric cylinder 24 is fixedly connected to the slide block 23 through a second connecting plate 232. When the slide block 23 slides along the slide rail 21 driven by the first electric cylinder 22, it drives the second connecting plate 232 on its upper part to slide synchronously along the slide rail 21, and the second connecting plate 232 drives the second electric cylinder 24 to slide synchronously along the slide rail 21.

[0034] In some examples, the clamping assembly 27 includes a connecting rod 275. The output shaft of the first motor 26 is fixedly connected to the connecting rod 275 of the clamping assembly 27 through a coupling. When the first motor 26 operates, it drives the connecting rod 275 at one end to rotate. The connecting rod 275 drives the clamping assembly 27 to rotate synchronously. By controlling the number of rotation turns and the rotation direction of the first motor 26, the angle of the clamping assembly 27 can be flexibly adjusted.

[0035] In some examples, a chamber is formed between the rubber layer 272 and the base 271. A plurality of groups of steel balls 273 are located in the chamber. In the initial state, the air pressure in the inner chamber of the rubber layer 272 is balanced with the external atmospheric pressure. The plurality of groups of steel balls 273 in the chamber are in a loose state, and the positions of the plurality of groups of steel balls 273 can change correspondingly with the external force. When the air pump assembly 28 evacuates the inner chamber of the rubber layer 272, the excess air in the chamber is discharged through the hose 29, and the air pressure decreases. Under the action of the external atmospheric pressure, the rubber layer 272 undergoes corresponding elastic deformation, squeezing the plurality of groups of steel balls 273, so that the plurality of groups of steel balls 273 are closely attached together.

[0036] In some examples, the air nozzle 274 of the clamping assembly 27 is communicated with the chamber of the clamping assembly 27, and the hose 29 is communicated with the air nozzle 274 of the clamping assembly 27. The hose 29, the air nozzle 274 and the chamber of the clamping assembly 27 are communicated, and gas can be filled into the chamber of the clamping assembly 27 through the hose 29, and the gas in the chamber of the clamping assembly 27 can also be extracted through the hose 29.

[0037] By adopting the above technical solutions: By evacuating and inflating the inner chamber of the rubber layer 272 through the air pump assembly 28, the motion state of the plurality of groups of steel balls 273 in the chamber is changed. When positioning the part to be clamped of the wrapped cross member body 7, the plurality of groups of steel balls 273 are in a loose state, adapting to the outer contour shape of the part to be clamped of the cross member body 7 and wrapping around the outside of the part to be clamped. Then, the excess air in the chamber of the rubber layer 272 is extracted through the air pump assembly 28. Under the action of the external atmospheric pressure, the rubber layer 272 undergoes corresponding elastic deformation, squeezing the plurality of groups of steel balls 273. The plurality of groups of steel balls 273 in the chamber of the rubber layer 272 are closely attached together and can no longer move freely. By clamping the part to be clamped of the cross member body 7 with the plurality of groups of steel balls 273, the clamping and fixing of the cross member body 7 are realized, and the wrapping of the special-shaped structure can be achieved.

[0038] The first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4, and the fourth clamping mechanism 5 are independently arranged. The horizontal position, height position, and angle of the clamping assembly 27 at the end of each clamping mechanism can be adjusted separately under the drive of the first electric cylinder 22, the second electric cylinder 24, and the first motor 26, which is suitable for clamping cross members of different sizes and specifications. One set of clamping devices can clamp multiple groups of cross member bodies 7.

[0039] Embodiment 2: Based on Embodiment 1, this embodiment introduces the specific structure of the supporting mechanism 6 in a clamping device for cross member production. The supporting mechanism 6 includes a linear drive base 61. The linear drive base 61 includes a slide table 62, and a third electric cylinder 63 is installed on the slide table 62. One end of the push rod of the third electric cylinder 63 is fixedly connected to a supporting table 64.

[0040] Among them, when the third electric cylinder 63 works, it can drive the supporting table 64 to move axially to adjust the height position of the supporting table 64. When the cross member body 7 is placed on the supporting table 64, the lifting height of the cross member body 7 is adjusted through the supporting table 64. When the linear drive base 61 works, it can drive the supporting table 64 to move horizontally, and the supporting table 64 can move in and out under the drive of the linear drive base 61.

[0041] When clamping the cross member body 7, the supporting table 64 moves into the supporting position under the drive of the linear drive base 61 to support the cross member body 7. After the cross member body 7 is clamped and fixed, the third electric cylinder 63 drives the supporting table 64 to move down a certain distance, and the linear drive base 61 drives the supporting table 64 to move horizontally out, without blocking the lower structure of the cross member body 7, which helps the smooth progress of the processing operation of the cross member body 7.

[0042] In some examples, the linear drive base 61 includes a second motor 611, the output shaft of the second motor 611 is connected to a lead screw 612, and slide rods 613 are arranged on both sides of the lead screw 612.

[0043] In some examples, both the slide rods 613 and the lead screw 612 penetrate through the slide table 62, and the slide table 62 is slidably connected to the slide rods 613.

[0044] Among them, when the second motor 611 works, it drives the lead screw 612 to rotate, and then drives the slide table 62 to slide along the slide rods 613. The slide table 62 drives the upper supporting table 64 to slide synchronously along the slide rods 613 to adjust the horizontal position of the supporting table 64, and realize the in and out movement of the supporting table 64.

[0045] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
