DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figures 1 to 6 As shown, the tooling fixture for processing automobile parts of the present invention, which is easy to disassemble, comprises a base 11, a bracket plate 1 is mounted on the base 11, a clamping mechanism is mounted on the bracket plate 1, and the clamping mechanism is used to clamp and fix the parts;

[0028] The clamping mechanism comprises a mounting block 2, which is mounted on the bracket plate 1. A slide groove 21 is provided on the mounting block 2. The slide groove 21 is distributed in a "cross" shape. A slider 23 is installed in the slide groove 21. A screw 22 is installed in the slide groove 21. The screw 22 drives the slider 23 to move. The spiral directions of the two ends of the screw 22 are opposite. A clamping plate 24 is installed on the slider 23.

[0029] An elastic layer 242 is provided on the surface of the card plate 24, a metal sheet 243 is installed on the surface of the elastic layer 242, and the metal sheet 243 is in contact with the surface of the accessory;

[0030] During operation, the automobile parts are placed on the mounting block 2 so that the parts are located between the clamping plates 24. After that, the staff manually or through the controller drives the screw 22 to rotate with the motor so that the clamping plates 24 move toward the automobile parts so that the automobile parts are clamped and fixed by the clamping plates 24.

[0031] At the same time, since the elastic layer 242 is installed on the surface of the clamping plate 24, when the clamping plate 24 clamps and fixes the automobile parts, the elastic layer 242 will deform adaptively, so that the elastic layer 242 fully fits on the surface of the automobile parts, thereby facilitating the clamping and fixing of different automobile parts, and expanding the adaptability and use range of the fixture;

[0032] At the same time, by installing the uniformly distributed metal sheets 243 on the elastic layer 242, when the elastic layer 242 is deformed and adheres to the surface of the automobile part, the position and angle of the metal sheets 243 on the elastic layer 242 will also change, so that the metal sheets 243 deform and move together with the elastic layer 242, so as to adhere to the surface of the automobile part, and isolate the elastic layer 242 from the surface of the automobile part to avoid direct contact between the two, and prevent burrs, protrusions and other defects on the automobile part from piercing and scratching the elastic layer 242, affecting the normal use of the elastic layer 242 and affecting the service life of the elastic layer 242;

[0033] At the same time, the slider 23 and the clamping plate 24 are driven to move by the screw 22 to clamp and fix the auto parts. After the clamping plate 24 clamps and fixes the auto parts, self-locking will occur between the screw 22 and the slider 23 to prevent the auto parts from loosening or falling off after clamping, thereby ensuring a good clamping and fixing effect. At the same time, by setting up multiple groups of clamping plates 24, different auto parts can be conveniently clamped and fixed, thereby improving the clamping speed of the tooling fixture. In combination with the elastic layer 242 and the metal sheet 243, the clamping stability of the tooling fixture is improved, which is convenient for the actual operation and installation of the staff, and improves the production efficiency and processing accuracy.

[0034] As an embodiment of the present invention, the metal sheet 243 includes a fixed end 2431 and a tilted end 2432, the fixed end 2431 is installed on the elastic layer 242, the tilted end 2432 is tilted relative to the fixed end 2431, and the tilted direction of the tilted end 2432 points to the surface of the mounting block 2;

[0035] During operation, since the raised end 2432 on the metal sheet 243 faces the surface of the mounting block 2, when the clamping plate 24 drives the elastic layer 242 and the metal sheet 243 to contact and squeeze the surface of the automobile accessory, the raised end 2432 will generate a force on the automobile accessory that is obliquely directed to the surface of the mounting block 2, so that the automobile accessory has a tendency to move toward the surface of the mounting block 2, thereby preventing the automobile accessory from falling off between the clamping plates 24 when the automobile accessory is clamped and fixed and the processing of the automobile accessory begins, or the automobile accessory with an uneven surface is squeezed by the clamping plate 24 and squeezed out and slides down, affecting the normal use of the tooling fixture and the processing effect of the automobile accessory.

[0036] As an embodiment of the present invention, the surface of the metal sheet 243 is subjected to sandblasting treatment;

[0037] After the surface of the metal sheet 243 is subjected to sandblasting treatment, the surface roughness of the metal sheet 243 increases. When clamping and fixing automotive parts, the frictional force between the metal sheet 243 and the automotive parts will increase, reducing the possibility of the automotive parts sliding after being stressed during processing, preventing the automotive parts from slipping off the workbench fixture, and improving the effect of clamping and fixing the automotive parts.

[0038] As an embodiment of the present invention, a buffer layer 25 is installed at the middle position on the surface of the mounting block 2. A cavity is formed inside the buffer layer 25, and through holes are formed on the surface of the buffer layer 25. The through holes communicate with the cavity, and the cavity is divided into multiple independent adsorption zones;

[0039] Since the buffer layer 25 is located at the middle position on the surface of the mounting block 2, when the staff places the automotive parts to be processed on the mounting block 2, relative positioning of the automotive parts can be performed according to the buffer layer 25, so that the center of the automotive parts coincides with or is close to the middle of the mounting block 2. Thus, when the staff manually or drives the screw 22 to rotate by a motor, and the clamping plate 24 moves towards the direction of the automotive parts, the moving distances of each clamping plate 24 are similar, preventing the clamping plate 24 from driving the automotive parts to slide on the surface of the mounting block 2 during the moving process, which may affect the clamping and fixing of the automotive parts by the workbench fixture, as well as the clamping speed and stability of the automotive parts, and further affect the subsequent production efficiency and processing accuracy;

[0040] At the same time, when the clamping plate 24 just touches the surface of the automotive parts, the staff manually presses the automotive parts to make the surface of the automotive parts in contact with the buffer layer 25 on the surface of the mounting block 2 closely combined. When the clamping plate 24 subsequently continues to squeeze and fully clamp and fix the automotive parts, the automotive parts can move towards the mounting block 2 under the action of the upturned end 2432 of the metal sheet 243, ensuring the stable clamping of the automotive parts on the workbench fixture and preventing the automotive parts from detaching from the workbench fixture, which may affect the normal use of the workbench fixture;

[0041] Meanwhile, since the buffer layer 25 is internally provided with a cavity and through holes are formed in the buffer layer 25, when the automotive part contacts and presses the buffer layer 25, the surfaces of the automotive part and the buffer layer 25 in contact with each other will be affected by the negative pressure at the through holes in the buffer layer 25 and adsorbed and fixed, thereby improving the fixing effect on the automotive part and ensuring the clamping stability and clamping and fixing effect of the automotive part on the tooling fixture. At the same time, when the automotive part is placed on the mounting block 2, the worker can press the automotive part so that the automotive part is adsorbed and fixed by the through holes in the buffer layer 25, so as to fix and position the automotive part in advance, which is convenient for the subsequent screw rod 22 to drive the clamping plate 24 to move for clamping and fixing, and avoids the movement of the automotive part during the fixing process of the clamping plate 24, affecting the clamping speed and clamping stability.

[0042] As an embodiment of the present invention, a mounting rod 244 is installed on the clamping plate 24, a fixing hole is formed in the slider 23, and the mounting rod 244 is clamped and installed in the fixing hole;

[0043] Since the clamping plate 24 adapts to different automotive parts through the installed elastic layer 242 and metal sheet 243, thereby improving the clamping stability of the automotive parts. Therefore, when clamping larger or smaller automotive parts, the clamping plate 24 is detached from the slider 23, and a clamping plate 24 matching the size of the automotive part is replaced, so as to improve the clamping speed and clamping stability of larger or smaller automotive parts and improve the clamping and fixing effect on the automotive parts.

[0044] As an embodiment of the present invention, a mounting hole 241 is formed in the clamping plate 24, a pressing rod 26 is inserted into the mounting hole 241, the pressing rod 26 includes a horizontal rod 261 and vertical rods 262 at both ends of the horizontal rod 261, the vertical rods 262 are inserted into the mounting hole 241, and the horizontal rod 261 presses the part;

[0045] Since the shapes of automotive parts are different, when clamping and fixing an automotive part with a relatively large length or height, the clamping plate 24 is used to clamp and fix one end of the automotive part close to the mounting block 2. Then, the vertical rods 262 at both ends of the pressing rod 26 are inserted into the mounting holes 241 in the clamping plate 24, and the horizontal rod 261 on the pressing plate contacts and presses the other end of the automotive part away from the mounting block 2, so as to realize the fixation of both ends of the automotive part with a relatively large length or height, and avoid the vibration or shaking of the automotive part with a relatively large length or height during processing, resulting in the automotive part falling off the tooling fixture or the other end of the automotive part being in a suspended state, resulting in an over-stressed situation and causing damage to the automotive part, affecting the processing quality of the automotive part;

[0046] Meanwhile, since the vertical rod 262 is perpendicular to the horizontal rod 261, and in combination with the relatively high-precision dimensional fit between the vertical rod 262 and the mounting hole 241, the pressure rod 26 can only be pulled out after being subjected to a force perpendicular to the end face of the clamping plate 24, avoiding the pressure rod 26 from slipping out and falling off due to vibration during the processing, which affects the clamping and fixing effect of the automotive parts.

[0047] Meanwhile, since there are multiple groups of mounting holes 241 provided on the clamping plate 24, in actual application, according to the specific shape of the automotive parts, the mounting method of the pressure rod 26 is any one of the following two: both ends of the pressure rod 26 are respectively mounted in the mounting holes 241 on two opposite clamping plates 24, and both ends of the pressure rod 26 are respectively mounted in the mounting holes 241 on two adjacent clamping plates 24.

[0048] As an embodiment of the present invention, the vertical rod 262 on the pressure rod 26 inclines away from the horizontal rod 261, and a rubber ring 263 is mounted at the lower end of the vertical rod 262.

[0049] By setting the included angle between the vertical rod 262 and the horizontal rod 261 to be greater than 90 degrees, that is, the vertical rod 262 inclines away from the horizontal direction, after the vertical rod 262 is inserted into the mounting hole 241, there will be an interaction force between the vertical rod 262 and the mounting hole 241, thus avoiding the pressure rod 26 from detaching from the mounting hole 241 during the processing, which affects the clamping stability of the automotive parts. At the same time, by mounting the rubber ring 263 on the vertical rod 262, when the vertical rod 262 is inserted into the mounting hole 241, the rubber ring 263 contacts and generates friction with the inner wall of the mounting hole 241, ensuring that after the vertical rod 262 is inserted into the mounting hole 241, the pressure rod 26 needs to be subjected to an external force, such as being manually pulled by a worker, before it can detach from the mounting hole 241, further ensuring the clamping stability of the automotive parts and avoiding affecting the application operation and installation, thereby ensuring good production efficiency and processing accuracy.

[0050] As an embodiment of the present invention, a rotating shaft 12 is mounted on the mounting block 2, the rotating shaft 12 is mounted on the support plate 1, a turntable 13 is mounted at the end of the rotating shaft 12 away from the mounting block 2, and a screw 14 is mounted on the turntable 13 to lock the rotation of the turntable 13.

[0051] When machining in other directions of auto parts is required, the operator turns the screw 14 to release the locking of the turntable 13. Then, the operator rotates the turntable 13, which drives the rotation of the rotating shaft 12 and the mounting block 2, so that the auto parts are rotated to the required angle or direction. Then, the operator turns the screw 14 again to lock the rotation of the turntable 13, which facilitates the machining of auto parts, avoids the cumbersome operations caused by reinstalling the auto parts and the accumulation of errors during clamping, and thus improves production efficiency and machining accuracy.

[0052] The specific working process is as follows:

[0053] During operation, the auto parts are placed on the mounting block 2 so that the parts are located between the clamping plates 24. Then, the operator manually or drives the screw rod 22 to rotate through the controller with a motor, so that the clamping plates 24 move towards the auto parts, and the auto parts are clamped and fixed by the clamping plates 24.

[0054] At the same time, since an elastic layer 242 is installed on the surface of the clamping plate 24, when the clamping plate 24 clamps and fixes the auto parts, the elastic layer 242 will undergo adaptive deformation, so that the elastic layer 242 fully fits on the surface of the auto parts, which facilitates the clamping and fixing of different auto parts.

[0055] At the same time, when the elastic layer 242 fits on the surface of the auto parts, the metal sheet 243 isolates between the elastic layer 242 and the surface of the auto parts, avoiding direct contact between the two, and preventing burrs, protrusions and other defects on the auto parts from piercing and scratching the elastic layer 242.

[0056] At the same time, the screw rod 22 drives the slider 23 and the clamping plate 24 to move, so as to clamp and fix the auto parts. After the clamping plate 24 clamps and fixes the auto parts, self-locking will occur between the screw rod 22 and the slider 23. At the same time, by setting multiple groups of clamping plates 24, it is convenient to clamp and fix different auto parts, improve the clamping speed of the tooling fixture, and cooperate with the elastic layer 242 and the metal sheet 243 to improve the clamping stability of the tooling fixture.

[0057] Since the upturned end 2432 of the metal sheet 243 faces the surface of the mounting block 2, when the clamping plate 24 drives the elastic layer 242 and the metal sheet 243 to contact and squeeze the surface of the auto parts, the upturned end 2432 will generate a force obliquely pointing to the surface of the mounting block 2 on the auto parts, so that the auto parts tend to move towards the surface of the mounting block 2, avoiding the situation that the auto parts fall off between the clamping plates 24 or the uneven surface auto parts are extruded and slipped off after being squeezed by the clamping plates 24 when clamping and fixing the auto parts and starting to machine the auto parts.

[0058] After the surface of the metal sheet 243 is frosted, the surface roughness of the metal sheet 243 increases, and when the automobile part is clamped and fixed, the friction between the metal sheet 243 and the automobile part increases, thereby reducing the possibility of the automobile part sliding after being stressed during processing;

[0059] Since the buffer layer 25 is located in the middle of the surface of the mounting block 2, when the worker places the automobile part to be processed on the mounting block 2, the automobile part can be relatively positioned according to the buffer layer 25, so that the center of the automobile part coincides with or is close to the middle of the mounting block 2, so that when the subsequent clamping plate 24 moves toward the automobile part, the distances moved by each clamping plate 24 are close;

[0060] At the same time, when the clamping plate 24 just touches the surface of the automobile part, the staff manually presses the automobile part to make the surface of the automobile part facing the mounting block 2 and the buffer layer 25 tightly bonded, so that when the clamping plate 24 continues to squeeze and fully clamp the automobile part, the automobile part can move toward the mounting block 2 under the action of the raised end 2432 on the metal sheet 243;

[0061] At the same time, since the buffer layer 25 has a cavity inside and a through hole on the buffer layer 25, when the automobile part contacts and squeezes the buffer layer 25, the surface where the automobile part and the buffer layer 25 contact each other will be affected by the negative pressure at the through hole on the buffer layer 25 and be adsorbed and fixed; at the same time, when the automobile part is placed on the mounting block 2, the staff can press the automobile part so that the automobile part is adsorbed and fixed by the through hole on the buffer layer 25, so as to fix and position the automobile part in advance;

[0062] When clamping larger or smaller auto parts, the clamping plate 24 is removed from the slider 23 and replaced with a clamping plate 24 that matches the size of the auto parts, thereby improving the clamping speed and stability of the larger or smaller auto parts.

[0063] When clamping and fixing an automobile accessory with a relatively large length or height, the clamping plate 24 is used to clamp and fix one end of the automobile accessory close to the mounting block 2, and then the vertical rods 262 at both ends of the pressure rod 26 are inserted into the mounting holes 241 on the clamping plate 24, and the horizontal rods 261 on the pressure plate are made to contact and press the end of the automobile accessory away from the mounting block 2, thereby achieving the fixation of both ends of the automobile accessory with a relatively large length or height;

[0064] At the same time, since the vertical rod 262 and the horizontal rod 261 are perpendicular to each other, and the vertical rod 262 and the mounting hole 241 have a relatively high precision size match, the pressure rod 26 can be pulled out only after being subjected to a force perpendicular to the end surface of the clamping plate 24;

[0065] At the same time, since the card plate 24 is provided with multiple groups of mounting holes 241, in actual application, according to the specific shape of the automobile accessories, the pressure rod 26 is installed in any of the following two ways: the two ends of the pressure rod 26 are respectively installed in the mounting holes 241 on the two opposite card plates 24, or the two ends of the pressure rod 26 are respectively installed in the mounting holes 241 on the two adjacent card plates 24;

[0066] By setting the included angle between the vertical rod 262 and the horizontal rod 261 to be greater than 90 degrees, that is, the vertical rod 262 is inclined away from the horizontal direction, so that after the vertical rod 262 is inserted into the mounting hole 241, there will be an interaction force between the vertical rod 262 and the mounting hole 241, thereby preventing the pressure rod 26 from being separated from the mounting hole 241 during the processing. At the same time, a rubber ring 263 is installed on the vertical rod 262, so that during the process of inserting the vertical rod 262 into the mounting hole 241, the rubber ring 263 and the inner wall of the mounting hole 241 contact and generate friction with each other, thereby ensuring that after the vertical rod 262 is inserted into the mounting hole 241, the pressure rod 26 needs to be subjected to an external force, such as manual pulling by a staff member, before it can be separated from the mounting hole 241;

[0067] When it is necessary to process the auto parts in other directions, the staff turns the screw 14 to unlock the turntable 13. After that, the staff rotates the turntable 13, thereby driving the rotating shaft 12 and the mounting block 2 to rotate, so that the auto parts are rotated to the required angle or direction, and then re-tightens the screw 14 to lock the rotation of the turntable 13, thereby facilitating the processing of the auto parts, avoiding the tedious operations caused by re-clamping the auto parts and the accumulation of errors during clamping, thereby improving production efficiency and processing accuracy.

[0068] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
