[0002] With the continuous development of the global economy and the continuous improvement of people's living standards, the demand for automobiles remains strong. During the welding process of automobiles, parts need to maintain a stable position during welding to ensure the accuracy and quality of welding. Therefore, they need to be clamped by an electric servo automatic clamp. The electric servo automatic clamp can achieve precise force and position control and can be adjusted according to different workpieces and welding process requirements.

[0003] Existing electric servo automatic clamps usually rely on an electric servo system to drive the push rod to move up and down, thereby pushing the slider to slide inside the slide rail. The movement of the slider drives the connecting block, which then transmits this movement to the clamp on the housing, causing the clamp to rotate, thereby achieving the clamping or loosening of the parts.

[0004] The existing electric servo automatic clamp has certain defects during use: the increased friction on the contact surface between the slider and the slide rail will cause wear. During the wear process, the material surface of the slider and the outer shell will gradually be damaged to form tiny particles. The particle impurities will enter the gap between the slider and the slide rail. During rapid use, the slider will generate a lot of heat in the slide rail. Excessive temperature will affect the performance of the material, and at the same time cause increased noise and reduced precision, thereby reducing the accuracy of the clamp.

[0018] (4) The present invention can quickly and effectively remove the heat on the guide rail plate by setting a heat dissipation component and actively conveying gas through a fan. The flow of air inside the guide rail plate increases the heat dissipation area and improves the heat dissipation efficiency.

DETAILED DESCRIPTION

[0022] 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.

[0023] like Figure 1-Figure 2 As shown, an electric servo automatic clamp comprises a body clamping seat 1, a rotating plate 11 is rotatably provided on the top of the body clamping seat 1, a clamping plate 12 is fixedly connected to the rotating plate 11 through a rotating shaft is provided on the top of the body clamping seat 1, a push rod 13 is provided at the bottom of the body clamping seat 1 through the output end of the electric servo, a slider 14 is provided on the top of the push rod 13 and moves vertically up and down on the body clamping seat 1, and a connecting plate 15 rotatably connected to the rotating plate 11 is rotatably provided on the slider 14; It should be noted that: when the electric servo is started, its output end pushes the push rod 13 to move upward, and the push rod 13 drives the slider 14 to move vertically upward in the body clamping seat 1. As the slider 14 rises, the connecting plate 15 connected to the slider 14 starts to play a role, and the connecting plate 15 pushes the rotating plate 11 upward. Since one end of the rotating plate 11 is fixedly connected to the clamping plate 12 at the top of the body clamping seat 1 through a rotating shaft, and the rotating plate 11 is rotatably connected to the top of the body clamping seat 1, under the push of the connecting plate 15, the rotating plate 11 rotates around the connection point between it and the body clamping seat 1, and can rotate 135 degrees. The rotation of the rotating plate 11 drives the clamping plate 12 to rotate inward, gradually approaching the clamped object, and realizing the clamping action.

[0024] like Figure 2-Figure 6 As shown, the oil spray mist assembly 2 is arranged inside the main body clamping seat 1 and is used to spray the inside of the main body clamping seat 1. The oil spray mist assembly 2 includes: a collecting box 21, which is a square-shaped structure and has a groove 22 on its top to facilitate the insertion of the slider 14 and to collect impurities of the slider 14. An oil tank is arranged on the side of the collecting box 21 facing away from the groove 22 to store lubricating oil. The lubricating oil in the oil tank is in a static state when not working; there is at least one pressing generator 23, which is arranged on the collecting box 21 and is used to spray the lubricating oil inside the oil tank. It pushes the lubricating oil inside the oil tank out by generating pressure; a guide plate 24, which is vertical and installed in the inner cavity of the main body clamping seat 1 and fixedly connected to the collecting box 21, and the slider 14 is slidably connected to the inner side of the guide plate 24; there is at least one first nozzle 25, which is rectangularly arranged on the left and right sides of the guide plate 24; a sealing cover 26, which is a semi-arc structure , and is installed on the collecting box 21; wherein the collecting box 21 is fixedly connected to the guide rail plate 24 through an oil injection pipe. Since the slider 14 slides on the inner side of the guide rail plate 24, good lubrication is required during operation to reduce friction, extend the service life and ensure smooth operation. Therefore, the lubricating oil in the collecting box 21 needs to be transported to the vicinity of the guide rail plate 24 to provide lubrication for the sliding between the slider 14 and the guide rail plate 24. This manual provides an oil tank on the side of the collecting box 21 facing away from the groove 22 for storing lubricating oil. The collecting box 21 and the guide rail plate 24 are fixedly connected through the oil injection pipe. First, a stable channel is provided for transporting the lubricating oil from the oil tank in the collecting box 21 to the guide rail plate 24 area. Second, this fixed connection method structurally ensures the stability of the connection and avoids loosening of the connection due to factors such as vibration during the operation of the device (the oil injection pipe is embedded in the collecting box 21 and the guide rail plate 24, which is not shown in the drawings of the manual).

[0025] It should be noted that: when it is necessary to spray lubricating oil on the guide plate 24 and the slider 14, the push rod 13 moves up and down under the action of the electric servo, and the slider 14 is connected to the top of the push rod 13. As the push rod 13 moves, the slider 14 also moves vertically in the main clamping seat 1. When lubrication is needed, the push rod 13 drives the slider 14 to move in the direction of the collection box 21. After the slider 14 moves into the collection box 21, the extrusion force generated by its movement acts on the press generator 23. The press generator 23 is triggered after being subjected to the extrusion force, and the lubricating oil supply inside the oil tank is started, and the lubricating oil in the oil tank is lubricated. The oil is pushed out to enter the interior of the guide plate 24, the lubricating oil flows in the guide plate 24, and is sprayed out through the first nozzles 25 on the left and right sides of the guide plate 24, and the sprayed lubricating oil diffuses in the guide plate 24 in the form of oil mist, and then the push rod 13 drives the slider 14 to reset, and the slider 14 and the guide plate 24 are connected to provide lubrication for them. The present invention can automatically trigger the lubrication process through the movement of the push rod 13 and the slider 14, thereby improving the convenience and reliability of the equipment, and also ensuring that the slider 14 and the guide plate 24 always maintain a good lubrication state during long-term use, thereby reducing friction, wear and heat generation.

[0026] like Figure 1 and Figure 4 As shown, the front end of the main body clamping seat 1 is detachably connected to the heat sink 27, and the side of the collecting box 21 close to the oil tank is fixedly connected to the heat sink 27. The collecting box 21, the guide plate 24 and the heat sink 27 are all made of aluminum alloy. The aluminum alloy has good thermal conductivity, which makes it easy to transfer the heat of the guide plate 24 to the heat sink 27 through the collecting box 21 for heat dissipation, and at the same time cool the lubricating oil inside the oil tank.

[0027] It should be noted that: the heat sink 27, as a special heat dissipation component, has a relatively large surface area and can quickly dissipate the heat conducted from the collection box 21 to the surrounding environment. At the same time, the side of the collection box 21 close to the oil tank is fixedly connected to the heat sink 27, so that the lubricating oil inside the oil tank can also be indirectly cooled by the heat sink 27. As the heat is transferred from the guide plate 24 to the heat sink 27, the temperature near the oil tank decreases, thereby cooling the lubricating oil inside the oil tank.

[0028] Timely heat dissipation can prevent the guide plate 24 from being affected by overheating and affecting its performance and accuracy. Too high a temperature may cause problems such as material deformation and reduced hardness, thereby affecting the movement accuracy and stability of the slider 14 in the guide plate 24. At the same time, cooling the lubricating oil inside the oil tank can prevent the lubricating oil from deteriorating due to excessive temperature, extend the service life of the lubricating oil, keep the lubricating oil working at a lower temperature, and also improve its lubrication performance, further reducing the friction and wear between the slider 14 and the guide plate 24.

[0029] like Figure 6-Figure 7 As shown, the cross-section of the guide plate 24 is U-shaped, and its two vertical ends are arranged in an eight-shaped structure. A semicircular hole is opened in the middle of one end of the slider 14 close to the guide plate 24, and a semi-arc seat 241 is installed at one end of the guide plate 24 close to the slider 14, and the semi-arc seat 241 is slidably connected in the semicircular hole.

[0030] It should be noted that the design of the eight-shaped vertical end can guide the flow direction of the oil mist in the guide plate 24, so that the oil mist is more evenly distributed in the contact area between the slider 14 and the guide plate 24, thereby improving the cooling effect. At the same time, the sliding connection of the semi-arc seat 241 in the semicircular hole can further increase the contact area between the guide plate 24 and the slider 14, which makes the sprayed oil mist have more opportunities to adhere to the guide plate 24 and the slider 14. The increased contact area can improve the adhesion of the lubricating oil and prolong the residence time of the lubricating oil in the contact area, thereby continuously exerting the lubricating effect.

[0031] like Figure 6-Figure 7 As shown, an oil connecting plate 28 is installed on the top of the guide plate 24, the two ends of the oil connecting plate 28 are tightly attached to the eight-shaped part of the guide plate 24, the middle part of the oil connecting plate 28 is tightly attached to the semi-arc seat 241 and the surface of the guide plate 24, and an oil outlet hole is opened below the oil connecting plate 28, wherein the first nozzle 25 inside the guide plate 24 is fixedly connected to the oil outlet hole.

[0032] It should be noted that: when the oil spray mist assembly 2 sprays the lubricating oil into the area of ​​the guide plate 24, a part of the lubricating oil flows into the connecting oil plate 28. The two ends of the connecting oil plate 28 are close to the eight-shaped part of the guide plate 24, and the middle part is close to the semi-arc seat 241 and the surface of the guide plate 24. This allows the connecting oil plate 28 to flow part of the lubricating oil downward along the surface of the guide plate 24 and the semi-arc seat 241 under the action of gravity until it contacts the slider 14. The special position and shape of the connecting oil plate 28 of the present invention allows the lubricating oil to flow along a specific path and directly flow to the contact part between the slider 14 and the guide plate 24 and the semi-arc seat 241. This precise lubricating oil supply method ensures that key parts are fully lubricated, reduces friction and wear, and improves the operating efficiency and accuracy of the equipment.

[0033] like Figure 7 and 8 As shown, soft hair heads 142 are installed at the upper and lower ends of the slider 14 along the eight-shaped structure of the slider 14 and the outer edge of the semicircular hole, which are tightly attached to the surface of the guide plate 24 and the inner wall of the semi-arc seat 241.

[0034] It should be noted that when the slider 14 moves up and down in the guide plate 24, the soft hair heads 142 installed at the upper and lower ends thereof are in close contact with the surface of the guide plate 24 and the inner wall of the semi-arc seat 241. Due to the soft characteristics of the soft hair heads 142, it can generate a certain friction force when it contacts the guide plate 24 and the semi-arc seat 241, thereby brushing off the impurities attached to the surface of the guide plate 24 and the inner wall of the semi-arc seat 241. The brushed off impurities will move along the surface of the guide plate 24 toward the collection box 21 under the push of the slider 14, and be collected inside the collection box 21. Cleaning the impurities on the guide plate 24 in time can prevent the impurities from entering the gap between the slider 14 and the guide plate 24, thereby avoiding affecting the movement accuracy of the slider 14. The groove 22 opened on the top of the collection box 21 is of key significance. When the slider 14 moves up, the impurities are pushed upward, but when the slider 14 moves down, due to the existence of the groove 22, the slider 14 will enter the groove 22 as a whole. At this time, the guide plate 24 and the groove 22 form a relatively continuous guiding channel. Under the action of gravity and the disturbance caused by the movement of the slider 14 again, the impurities will slide along this channel to the inside of the collection box 21, thereby achieving the purpose of the impurities falling into the collection box 21. Moreover, when the slider 14 extends into the collection box 21, the driving block 213, the side block 212 and the bonding block 214 and other components work together to squeeze and clean the three surfaces of the slider 14. This process not only cleans the impurities on the surface of the slider 14, but also the squeezing and disturbance generated in the collection box 21 are conducive to further gathering the impurities that may exist in the surrounding area to the bottom of the collection box 21, and can also reduce the impurities from being pushed upward along the guide plate 24.

[0035] like Figure 4 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the wiping assembly 211 is arranged in the collection box 21, and is used for automatically wiping the slider 14 when it is inserted into the collection box 21; the wiping assembly 211 includes: a mounting block 2111, which is in a U-shaped structure and is installed on a side of the collection box 21 close to the slider 14; a side block 212, the number of which is at least one, the side block 212 is adapted along the inclined direction of the slider 14, and is connected to the side wall of the collection box 21 by means of a slide rail; a driving block 213, which is in an L-shaped structure, and the driving block 213 rotates on the collection box 21 The vertical end of the side block 212 is connected to the side wall of the side block 212 by means of a slide rail; the fitting block 214, the middle of which is arc-shaped and the two ends of the arc are arranged horizontally, which is adapted to the bottom of the slider 14, and one side of the fitting block 214 is slidably connected to the horizontal end of the erection block 2111 by means of a slide rail through the horizontal end; the compression spring 215 is installed between the vertical end and the horizontal end of the erection block 2111 on one side of the side block 212 and the fitting block 214 respectively; the inclined plate 216 is installed below the side block 212;The passive plate 217 is installed at the left and right ends of the fitting block 214 and is tightly attached to the inclined plate 216. The transverse groove 140 is opened at the top ends of the slider 14, and the slider 14 is provided with an inclined groove 141 connected to the transverse groove 140 on one side close to the collecting box 21. Since the inclined groove 141 has a specific inclination angle, as the slider 14 continues to go deeper, the driving block 213 can only move along the inclined direction under the constraint of the inclined surface of the inclined groove 141. In this process, the driving block 213 gradually approaches the transverse groove 141. When the driving block 213 reaches the entrance of the transverse groove 140, under the continuous thrust of the slider 14, the driving block 213 will begin to enter the transverse groove 140 along the direction of the transverse groove 140. This transition from the inclined groove 141 to the transverse groove 140 causes the position of the driving block 213 on the collection box 21 to change. Since the sliding rail between the driving block 213 and the side block 212 cooperates, the change in position will inevitably cause the driving block 213 to rotate. When the transverse groove 140 and the inclined groove 141 on the slider 14 are connected, the driving block 213 will rotate. The transition between the grooves 141 prompts the driving block 213 to rotate, and the position of the driving block 213 changes and rotates, driving the side block 212 to contact along the side of the slider 14. At this time, the side block 212 begins to squeeze and clean the side of the slider 14 to remove impurities attached to the side. At the same time, the inclined plate 216 below the side block 212 moves with the movement of the side block 212. Since the inclined plate 216 is in close contact with the passive plates 217 on the left and right ends of the bonding block 214, the movement of the inclined plate 216 drives the passive plate 217 to lift upward, thereby prompting the bonding block 214 to contact with the bottom of the slider 14 to clean the bottom of the slider 14. As the slider 14 moves further, the side block 212 keeps in contact along the side of the slider 14, and the bonding block 214 also keeps in contact with the bottom of the slider 14, achieving stable squeezing and cleaning of the three surfaces (side and bottom) of the slider 14. Therefore, the slider 14 moves in the area within the groove 22. The slider 14 within this distance in this area can be cleaned, and all-round (side and bottom) cleaning of the slider 14 can be achieved. ;

[0036] It is worth noting that after cleaning is completed, the slider 14 leaves the collection box 21, and the compression spring 215 releases its elastic force to generate a force on the side block 212 and the bonding block 214. Under the action of the compression spring 215, the side block 212 and the bonding block 214 are reset to the initial position, waiting for the next extension of the slider 14 for cleaning. The wiping assembly 211 can automatically clean the slider 14 when it extends into the collection box 21, and the side block 212 and the fitting block 214 can squeeze and clean the three surfaces of the slider 14, thereby fully cleaning the impurities on the surface of the slider 14 and improving the cleaning effect; The driving block 213 and the bonding block 214 are provided with corrugated cotton on one side away from the collecting box 21 .

[0037] It should be noted that the corrugated cotton has more protrusions and depressions, which can better capture and remove impurities on the surface of the slider 14.

[0038] like Figure 4 and Fig.13 As shown, the heat dissipation component 221 is arranged on the main body clamping seat 1 below the collecting box 21, and is used to transport gas to the guide plate 24 and discharge hot gas from the guide plate 24. The top of the main body clamping seat 1 is provided with an inlet and outlet 111. The heat dissipation component 221 includes: a heat dissipation port 222, which is provided in the inner cavity of the main body clamping seat 1 and is located below the collecting box 21. The main body clamping seat 1 is provided with air openings at both ends of the heat dissipation port 222. A sealing cylinder is installed at one end of the heat dissipation port 222 close to the collecting box 21; a support frame 223, which is installed on the inner side of the heat dissipation port 222; a fan 224, which rotates on the support frame 223; a rack plate 2 25, which is installed on one side of the push rod 13; the gear 226, which is rotated on the support frame 223 through the rotating rod; the transmission wheels 227, which are two in number, rotate under the support frame 223 and are fixedly connected to the fan 224 and the rotating rod of the gear 226; the transmission belt 228, which is transmission-connected to the two transmission wheels 227; the air duct 229, which is two in number, is installed on the left and right ends of the sealing cylinder, and the end of the air duct 229 away from the sealing cylinder is fixedly connected to the guide plate 24; the second nozzle is arranged in a rectangular array on the guide plate 24, and is arranged at intervals from the first nozzle 25, and the second nozzle is fixedly connected to the air duct 229.

[0039] It should be noted that when the push rod 13 moves upward under the action of the electric servo, the rack plate 225 installed on one side of the push rod 13 also moves accordingly, and the movement of the rack plate 225 drives the gear 226 meshing therewith to rotate, and the gear 226 is connected to one of the transmission wheels 227 through the rotating rod, thereby driving the transmission wheel 227 to rotate, and the two transmission wheels 227 are connected through the transmission belt 228, so that the other transmission wheel 227 also rotates accordingly. This transmission wheel 227 is fixedly connected to the rotating rod of the fan 224, thereby driving the fan 224 to rotate on the support frame 223, so that the external drive gas enters the heat dissipation port 222 through the air opening, and the heat dissipation port 222 drives the gas to enter the sealing cylinder and pass through the inside of the air duct 229 under the action of the fan 224, so that the airflow flows inside the guide plate 24, exchanges heat with the guide plate 24, takes away the heat on the guide plate 24, and discharges it from the inlet and outlet 111. When the push rod 13 moves downward under the action of the electric servo, the opposite is true; It is worth noting that in order to prevent external impurities from entering the gas through the open pores and the inlet and outlet 111, a filtering device needs to be installed on the open pores and the inlet and outlet 111 to filter the impurities in the gas; By actively delivering gas through the fan 224, the heat on the guide plate 24 can be quickly and effectively removed. The flow of air inside the guide plate 24 increases the heat dissipation area and improves the heat dissipation efficiency. The second nozzle and the first nozzle 25 are arranged at intervals, so that the airflow can be more evenly distributed on the guide plate 24, further improving the heat dissipation effect of the guide plate 24, and further playing a cooling effect for the subsequent spraying of oil mist.

[0040] The working principle of the present invention is that it is used for an electric servo automatic clamp. When in use, the electric servo starts to push the push rod 13, driving the slider 14 to rise, and pushing the rotating plate 11 to rotate through the connecting plate 15, thereby driving the clamping plate 12 to rotate inward to achieve clamping. When it is necessary to spray lubricating oil on the guide plate 24 and the slider 14, the push rod 13 drives the slider 14 to move, and the slider 14 enters the collection box 21 to trigger the press generator 23, pushing the lubricating oil in the oil tank into the guide plate 24, and spraying oil mist from the first nozzle 25 to lubricate the slider 14 and the guide plate 24. The heat sink 27 is connected to the guide plate 24 through the collection box 21. The aluminum alloy material conducts heat and dissipates heat, and the guide plate 24 is dissipated and cooled. The oil tank lubricating oil, when the oil spray mist assembly 2 sprays the lubricating oil into the guide rail plate 24 area, a part of the lubricating oil flows in along the connecting oil plate 28, and under the action of gravity, can flow downward along the guide rail plate 24 and the surface of the semi-arc seat 241 until it contacts the slider 14, ensuring that the key parts are fully lubricated. When the slider 14 moves up and down in the guide rail plate 24, the soft hair head 142 is tightly attached to the surface of the guide rail plate 24 and the inner wall of the semi-arc seat 241, and can brush off the impurities attached to the surface of the guide rail plate 24 and the inner wall of the semi-arc seat 241. The brushed impurities will move along the surface of the guide rail plate 24 toward the collection box 21 under the push of the slider 14, and be collected inside the collection box 21; In the original state, the side block 212 and the bonding block 214 are in the collection box 21, not in the same vertical plane as the slider 14, and the compression spring 215 is in a natural state. When the slider 14 extends into the collection box 21, the driving block 213 enters the transverse groove 140 along the inclined groove 141 and rotates, driving the side block 212 to contact the side of the slider 14, and the inclined plate 216 under the side block 212 moves to lift the passive plate 217 of the bonding block 214, and the bonding block 214 contacts the slider 14. The side block 212 and the bonding block 214 squeeze the three sides of the slider 14 to clean impurities. After the cleaning is completed and the slider 14 leaves, the compression spring 215 resets the side block 212 and the bonding block 214 and waits for the next cleaning; The push rod 13 moves up and down under the action of the electric servo, driving the rack plate 225 to move, causing the gear 226 to rotate, and then driving the transmission wheel 227 to rotate, and another transmission wheel 227 to rotate through the transmission belt 228, driving the fan 224 to rotate, and the external air enters the heat dissipation port 222 through the air opening, and enters the sealing cylinder and the air duct 229 under the action of the fan 224. The airflow flows in the guide plate 24, exchanges heat with the guide plate 24, and takes away the heat and is discharged from the inlet and outlet 111. The second nozzle is arranged at an interval from the first nozzle 25, so that the airflow is more evenly distributed on the guide plate 24, thereby improving the heat dissipation effect and preparing for oil mist cooling.
