Specific embodiments

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Embodiment: A positioning device for automobile mold processing, as Figures 1 - 9 shown, includes a processing main body 1, a processing module 2 is fixedly installed above the processing main body 1, and the processing module 2 is an existing module, and devices with different functions can be selected according to needs, such as drilling, grinding and other devices; a mold body 3 to be processed is provided on the upper surface of the processing main body 1, and a plurality of groups of through grooves 101 are symmetrically opened on the upper surface of the processing main body 1. By providing the through grooves 101, the functions of guiding and limiting can be achieved.

[0022] Combined with the attached Figure 1 - Attached Figure 9 , by setting the positioning mechanism 4 for clamping and positioning the mold body 3, the mold body 3 can be quickly clamped and positioned before processing, ensuring the stability and processing accuracy of the mold body 3 during processing; the positioning mechanism 4 includes a turntable 401 and a round rod 407. The turntable 401 is arranged inside the processing main body 1, and the turntable 401 is sleeved on the surface of the output shaft of the driving motor. The driving motor is installed inside the processing main body 1, and the rotation of the driving motor can drive the turntable 401 to rotate synchronously, providing a power source for clamping the mold body 3; it is worth noting that the turntable 401 and the rotating shaft of the driving motor are connected by a bearing with friction damping; and the turntable 401 is fixedly connected to the outer ring of the bearing. The bearing with friction damping is a prior art, and its working principle is that friction damping is a mechanism that consumes energy or slows down motion through friction between objects. By setting the bearing with friction damping, when the driving motor rotates, it can first drive the turntable 401 to rotate synchronously. When the turntable 401 is blocked, as the driving motor continues to rotate, only the inner ring of the bearing with friction damping will rotate, and the turntable 401 will not follow the driving motor to continue rotating.

[0023] Among them, two groups of extrusion rods 402 are symmetrically installed on the surface of the turntable 401. By setting the extrusion rods 402, they can then rotate synchronously with the turntable 401 to achieve the extrusion function; at the ends of the two groups of extrusion rods 402 away from each other, there are mounting plates 403. By setting the mounting plates 403, when the extrusion rods 402 rotate synchronously with the turntable 401, they can extrude the mounting plates 403 to move away from the turntable 401; and the mounting plates 403 are slidably matched with the bottom surface of the processing main body 1; on the opposite surfaces of the two groups of mounting plates 403, baffle plates 4031 are fixedly installed. By setting the baffle plates 4031, the extrusion rods 402 can be blocked; it is worth noting that when the extrusion rods 402 extrude the mounting plates 403, as the turntable 401 continues to rotate, the extrusion rods 402 will eventually come into contact with the baffle plates 4031 and be blocked, so that when the driving motor continues to rotate, the turntable 401 will no longer rotate.

[0024] Among them, two sets of toothed plates 404 are symmetrically installed on the sides of the two sets of mounting plates 403 that are away from each other. By setting the toothed plates 404, they can move synchronously with the mounting plates 403. A limiting rod 4041 is slidably connected inside the toothed plate 404, and the end of the limiting rod 4041 is fixedly connected to the inner wall of the processing main body 1. By setting the limiting rod 4041, the toothed plate 404 can be supported, and at the same time, the movement of the toothed plate 404 can be guided and limited. A connecting spring 4042 is sleeved on the surface of the limiting rod 4041, and both ends of the connecting spring 4042 are fixedly connected to the inner wall of the processing main body 1 and the end of the toothed plate 404 respectively. By setting the connecting spring 4042, when the toothed plate 404 moves horizontally, the connecting spring 4042 can be compressed, and the connecting spring 4042 can generate a reaction force, so that the toothed plate 404 can be reset later.

[0025] Among them, a semi-gear 405 is meshed with the surface of the toothed plate 404. By setting the semi-gear 405, it can rotate towards the direction of the mold body 3 under the action of the toothed plate 404. The semi-gears 405 on the same side are connected by a round shaft 4051, and both ends of the round shaft 4051 are fixedly connected to the inner wall of the processing main body 1 through ear plates. By setting the round shaft 4051, the round shafts 4051 on the same side can rotate synchronously. A driven rod 406 is fixedly installed on the surface of the semi-gear 405. The driven rod 406 is arranged inside the through groove 101, and the driven rods 406 on the same side are all connected by a connecting plate. By setting the driven rod 406, it can rotate synchronously with the semi-gear 405. Among them, the driven rod 406 is composed of an outer sleeve rod 4061 and an inner sleeve rod 4062, and the inner sleeve rod 4062 is inserted inside the outer sleeve rod 4061. The inner sleeve rod 4062 is slidably matched with the inner wall of the outer sleeve rod 4061 through two sets of symmetrically installed sliders 4063 on the surface. By setting the outer sleeve rod 4061 and the inner sleeve rod 4062, the inner sleeve rod 4062 can slide inside the outer sleeve rod 4061 to achieve the purpose of lifting and lowering. A cavity 4064 is opened inside the inner sleeve rod 4062. Combined with the attached Figure 1 - attached Figure 9, inside the cavity 4064, there is a lifting member for lifting the mold to be processed, so that the mold body 3 can rise after being clamped, ensuring the stability of the processing position and the processing accuracy; the lifting member includes a lifting block 4065 slidably connected inside the cavity 4064, and the lifting block 4065 is elastically connected to the bottom surface of the cavity 4064 through an elastic spring. By setting the elastic spring, the reaction force generated by its deformation can drive the reset of the lifting block 4065; the lower end of the lifting block 4065 penetrates through the inner wall of the cavity 4064 and extends to the outside, and an electromagnet 4066 is fixedly installed at the lower end of the lifting block 4065. The electromagnet 4066 is electrically connected to a power supply switch 4067. By setting the power supply switch 4067 and the electromagnet 4066, the electromagnet 4066 can be powered by triggering the power supply switch 4067, so that the electromagnet 4066 generates magnetism; the power supply switch 4067 is installed on the bottom surface of the cavity 4064 and is located below the lifting block 4065; a magnetic plate 4068 is provided directly below the power supply switch 4067, and the magnetic plate 4068 is fixedly installed on the inner bottom surface of the outer sleeve rod 4061; by setting the magnetic plate 4068, it can cooperate with the electromagnet 4066; it should be noted that the opposite surfaces of the magnetic plate 4068 and the electromagnet 4066 have the same magnetism, that is, when the electromagnet 4066 is energized to generate magnetism, the upper surface of the magnetic plate 4068 below it has the same magnetism, forming a repulsive effect, so that the inner sleeve rod 4062 rises inside the outer sleeve rod 4061.

[0026] Among them, the round rod 407 is inserted into the inner sleeve rod 4062, and the round rod 407 is elastically connected to the inner wall of the inner sleeve rod 4062. By setting the round rod 407, it can move synchronously with the driven rod 406, and the round rod 407 can contract into the inner sleeve rod 4062 and compress the gas inside it, while achieving the purpose of clamping mold bodies 3 of different specifications. A positioning plate 408 is fixedly installed at the end of the round rod 407. By setting the positioning plate 408, the mold body 3 can be clamped and fixed, achieving the purpose of saving time.

[0027] Combined with the attached Figure 1 - attached Figure 9 , it also includes a cleaning mechanism 5 for cleaning the debris generated during the processing of the mold body 3, so that the debris generated during the processing of the mold body 3 can be intermittently cleaned, avoiding the influence of the debris during the processing of the mold body 3; the cleaning mechanism 5 includes a pulley group 501 sleeved on the surface of the output shaft of the driving motor. By setting the pulley group 501, the purpose of kinetic energy transmission can be achieved; it should be noted that the other end of the pulley group 501 is rotatably connected to the bottom surface of the processing main body 1; Wherein, a cylinder 502 is fixedly installed on the upper surface of the other end of the pulley group 501. By providing the cylinder 502, the functions of guiding and limiting can be achieved; a plurality of groups of elastic strips 503 are equidistantly installed on the inner wall of the cylinder 502. By providing the elastic strips 503, the functions of connection and limiting can be achieved; a curved rod 504 is provided above the cylinder 502. A plurality of groups of mating grooves 5041 are equidistantly formed in the surface of the curved rod 504. By providing the curved rod 504 and the mating grooves 5041, when the lower end of the curved rod 504 enters the inside of the cylinder 502, the elastic strips 503 will enter the inside of the mating grooves 5041 to clamp the curved rod 504, so that the curved rod 504 can rotate synchronously with the pulley group 501.

[0028] Wherein, the upper end of the curved rod 504 is movably connected to a cross plate 505. By providing the cross plate 505, the curved rod 504 can be positioned, and at the same time, when the cross plate 505 moves, the curved rod 504 can be driven to move synchronously; it should be noted that the upper end of the curved rod 504 is rotatably connected to the lower surface of the cross plate 505; a vertical rod 506 is fixedly installed on the upper surface of the cross plate 505. The upper end of the vertical rod 506 penetrates through the inner wall of the processing main body 1 and extends to the outside, and the vertical rod 506 is located directly below the left connecting plate. The vertical rod 506 is of a T-shaped structure, and the vertical rod 506 is elastically connected to the surface of the processing main body 1 through a compression spring. By providing the vertical rod 506 and the compression spring, when the driven rod 406 rotates to clamp and position the mold body 3, the upper end of the vertical rod 506 will be pressed by the connecting plate and the compression spring will be compressed, so that the vertical rod 506 drives the cross plate 505 to move downward synchronously; at the same time, the compressed compression spring will generate a reaction force, so that after the mold body 3 is processed, when the driven rod 406 rotates in the reverse direction to reset, the vertical rod 506 can be driven to reset.

[0029] Wherein, a piston cylinder 507 is provided on one side of the curved rod 504, and a rotary nozzle 508 is connected to the upper end of the piston cylinder 507. By providing the rotary nozzle 508, the debris generated during the processing of the mold body 3 can be cleaned. It should be noted that the rotary nozzle 508 is a prior art and can swing reciprocally when ventilated. A circular plate 509 is slidably fitted on the inner wall of the piston cylinder 507. By providing the circular plate 509, the gas inside the piston cylinder 507 can be compressed, so that the gas is discharged from the rotary nozzle 508 and acts on the mold body 3 to realize the cleaning of the debris. It should be noted that when the circular plate 509 resets, the external gas will be inhaled from the rotary nozzle 508. A connecting rod 510 is movably connected to the surface of the circular plate 509, which can play a connecting role. The end of the connecting rod 510 is movably connected to a collar 511, and the collar 511 is sleeved on the surface of the curved rod 504. By providing the collar 511, when the curved rod 504 rotates, the collar 511 can be driven to rotate synchronously, so as to drive the circular plate 509 to reciprocally move inside the piston cylinder 507, and the purpose of intermittently cleaning the debris on the surface of the mold body 3 is realized.

[0030] It should be noted that the number of components such as the extrusion rod 402, the mounting plate 403, and the toothed plate 404 for positioning the mold body 3 can be set according to needs, and is not limited to Figure 2 the two groups arranged symmetrically left and right shown in the figure, and two groups can also be symmetrically arranged front and back; but when adding symmetrically front and back, the position of the cleaning mechanism 5 needs to be adjusted correspondingly.

[0031] Specifically, when processing the mold body 3, the mold body 3 is placed in the notch opened on the surface of the processing main body 1, and then the driving motor is started, so that the turntable 401 drives the extrusion rod 402 to rotate synchronously, starts to squeeze the mounting plate 403 to move, and drives the semi-gear 405 to start rotating through the toothed plate 404, so that the semi-gear 405 drives the driven rod 406 to start rotating towards the mold body 3. The rotating driven rod 406 will drive the positioning plate 408 to rotate synchronously and start to contact the mold body 3, and start to clamp and position the mold body 3. When the positioning of the mold body 3 is completed, the round rod 407 will move inside the inner sleeve rod 4062 and compress the gas inside it, and act on the upper surface of the lifting block 4065, so that the lifting block 4065 drives the electromagnet 4066 to move downward synchronously. At the same time, the lifting block 4065 will compress the power supply switch 4067, so that the electromagnet 4066 starts to be energized and forms a repulsion with the magnetic plate 4068, so that the inner sleeve rod 4062 can rise inside the outer sleeve rod 4061, thereby driving the clamped mold body 3 to move upward, so as to reduce the influence of equipment vibration on the mold body 3 and ensure the stability and accuracy during the processing of the mold body 3.

[0032] While the positioning of the mold body 3 is completed, the extrusion rod 402 begins to contact the baffle 4031, so that when the driving motor continues to rotate, the turntable 401 no longer rotates; and the connecting plate on the left side presses the vertical rod 506, causing the vertical rod 506 to drive the cross plate 505 to start moving downward synchronously, causing the curved rod 504 to start moving downward synchronously with the cross plate 505. The lower end of the curved rod 504 also enters the inside of the cylinder 502 and presses the elastic strip 503. After the curved rod 504 finishes descending, the elastic strip 503 enters the inside of the fitting groove 5041 to fix the curved rod 504. Then, as the driving motor continues to rotate, it drives the curved rod 504 to start rotating through the pulley set 501. The rotating curved rod 504 then drives the collar 511 to rotate synchronously. The rotating collar 511 drives the circular plate 509 to reciprocate inside the piston cylinder 507 through the connecting rod 510, compressing the gas inside the piston cylinder 507, causing the gas to be discharged from the rotary nozzle 508 and act on the surface of the mold body 3 to clean the debris generated during the processing of the mold body 3, ensuring the processing accuracy and efficiency of the mold body 3.
