[0007] Preferably, the clamping mechanism includes a fixed arm fixedly connected to one end of the moving arm away from the elastic rod, two fixed partitions are fixedly connected to the outer wall of the fixed arm, and the outer wall of the fixed partition is slidably connected to the outer wall of the outer frame. A transmission mechanism and a clamping mechanism are provided inside the device. Before use, only the power supply needs to be connected, and the parts to be clamped are placed on the platform of the device. When several clamping columns are combined together, when the motor drives the gear to rotate, the gear drives the two moving arms moving outside, so that the fixed arm moves towards the center.

[0008] Preferably, the clamping mechanism further includes a housing fixedly connected to the outer wall of the fixed arm, a second housing is fixedly connected to the outer wall of the housing, a fixator is rotatably connected to the inner wall of the housing, and teeth are provided on the outer wall of the fixator.

[0009] Preferably, the clamping mechanism further includes a ejector rod meshed and connected to the outer wall of the tooth, the outer wall of the ejector rod is slidably connected to the inner wall of the second housing, one end of the ejector rod away from the tooth is rotatably connected to a round wheel, the outer wall of the round wheel is slidably connected to the inside of the chute, and a fixing mechanism is arranged on the inner wall of the housing.

[0010] Preferably, the fixing mechanism includes a plurality of fixing plates fixedly connected to the outer wall of the housing, a plurality of chutes II are opened on the outer wall of the fixator, a clamping block is fixedly connected to the outer wall of the plurality of fixing plates, a sliding column is fixedly connected to the outer wall of the plurality of fixing plates, the outer wall of the sliding column is slidably connected to the inner wall of the chute II, and a fitting mechanism is arranged on the inner wall of the outer frame.

[0011] Preferably, the fitting mechanism includes a plurality of spring telescopic rods fixedly connected to the outer wall of the outer frame, and a fixing module is fixedly connected to one end of the plurality of spring telescopic rods away from the outer frame.

[0012] Preferably, the fitting mechanism further includes a clamping column fixedly connected to the outer wall of the fixing module away from the spring telescopic rod. The clamping column installed on the fixing arm moves forward. When the clamping column contacts the surface of the workpiece, the clamping column will cooperate with multiple clamping columns to tightly fit the fitting when clamping the fitting. Through the spring telescopic rod at the rear end of the clamping column, the lengths of the clamping columns are changed so as to fit different length parts of the fitting, squeeze fittings of different shapes, clamp the outer wall of the fitting by the clamping column, and multiple clamping columns are in contact and close to the outer walls of different parts of the fitting. According to the shape of the fitting, the multiple clamping columns are squeezed to cause the spring telescopic rods behind the different clamping columns to retract backward, so that the multiple clamping columns tightly fit the outer wall of the fitting. According to different fitting appearances, the clamping columns form different lengths. Through the cooperation of the above components, according to different fitting appearances, the forces received by the spring telescopic rods are different and the contractions are different, so as to change the surface shape formed by the multiple clamping columns to be consistent with the fitting, thereby clamping and fixing different fittings.

[0013] Preferably, the fitting mechanism further includes a moving plate rotatably connected to the outer wall of the clamping column, and a rubber hard plate is rotatably connected to the outer wall of the moving plate. Using the characteristics of the above-mentioned clamping column to expand and contract in length, when the clamping column approaches the surface of the workpiece. Through the moving plate and the rubber hard plate rotatably connected to the front end of the clamping column, the moving plate rotates in a plane with the clamping column, while the rubber hard plate rotates up and down with the moving plate. When the rubber hard plate approaches the surface of the fitting, through the up and down rotation of the rubber hard plate and its own characteristics, it cooperates with the plane rotation of the moving plate to better approach the surface of the workpiece. When the rubber hard plate rotates up and down, the rubber hard plate is obliquely pressed against the fitting, and the rotation connection between the moving plate and the clamping column can provide support at multiple angles. Through the above components, by fitting the surface of the fitting at multiple angles, the contact area with the fitting is increased, and the deviation caused by single-point contact is avoided.

[0014] Preferably, the closing mechanism also includes a spring returner fixedly connected to the outer wall of the movable plate, and one end of the spring returner away from the movable plate is fixedly connected to the inner wall of the rubber hard plate. The fixed arm moves toward the middle of the device under the drive of the movable arm. When the clamping column on the clamping mechanism is squeezed and fitted on the outer wall of the accessory, the round wheel connected to the bottom of the push rod rotates and moves forward to the protrusion along the slide groove opened on the outer frame. When the round wheel moves to the front end protrusion of the slide groove, it drives the push rod to move upward along the second shell, and the push rod connected to the fixer on the other side moves downward, so that the fixer rotates to one end. When the fixer rotates When the second slide groove on the fixture rotates, it will drive the slide column to move, thereby controlling the surrounding fixed plates to move closer to the middle of the fixture. The clamping block installed on the fixed plate will be close to the fixed module, so that the clamping column is close to the outer wall of the accessory, and the fixed module is clamped and fixed by the clamping block. After the accessory is fixed, the shape of the accessory formed by the clamping column is fixed, so as to avoid the impact of multiple clamping columns on the subsequent processing of the accessory, causing it to shake backward and produce gaps. By fixing the fixed module, the spring telescopic rod stops telescoping and keeps in a fixed state to reduce the shaking. A slot mechanism is provided on the inner wall of the outer frame.

[0015] Preferably, the slot mechanism includes a groove 1 fixedly connected to the inner wall of the outer frame, a protrusion is fixedly connected inside the groove 1, the inner part of the groove 1 is slidably connected to the outer wall of the elastic rod, and a fixed groove is provided on the outer wall of the protrusion. By utilizing the force of the moving arm, when the moving arm drives the fixed arm to move toward the middle, the elastic rod at the other end of the moving arm will move toward the outer end and enter the groove 1 provided inside the outer frame. Due to its own elasticity, the elastic rod touches the outer wall of the protrusion when it moves, and moves forward to the bottom along the left side of the protrusion in the moving direction, leaving the resistance range of the protrusion. The elasticity of the rod itself will return to its straight direction, thereby entering the fixed groove to prevent the moving arm from moving in the opposite direction to affect the clamping and fixation of the upper end after the motor stops. When the motor starts working, the elastic rod continues to move forward, and the elastic rod moves along the outer wall of groove one through the outer wall of groove one to fall off the fixed groove. The motor then rotates in the opposite direction to leave groove one. Through the above-mentioned components, the moving arm can be locked to a certain extent during operation through the cooperation of various components, so that the upper clamping mechanism is synchronously locked and cannot move left and right, thereby avoiding the loosening of the clamping mechanism caused by the motor stopping, which may cause the accessories to fall off.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention aims to solve the problem of long replacement time of accessory clamps. A transmission mechanism and a clamping mechanism are arranged inside the device. Before use, it is only necessary to turn on the power supply. When the motor drives the gear to rotate, the clamping column installed on the fixed arm moves synchronously. When the clamping column contacts the surface of the accessory, multiple clamping accessories are attached. The spring telescopic rod at the rear end of the clamping column changes the length of each clamping column so that it can be attached to the uneven surface of the accessory surface, and accessories of different shapes are squeezed. Multiple clamping columns are contacted and attached to the outer wall of the accessory at different places. According to the different appearances of the accessories, the clamping columns are formed into different lengths. The final surface shape is consistent with the appearance of the accessory, so that different accessories can be clamped and fixed.

[0018] (2) The present invention utilizes the telescopic characteristics of the clamping column. When the clamping column is close to the surface of the accessory, the movable plate and the rubber hard plate connected by the front end of the clamping column rotate in the plane of the movable plate and the clamping column, and the rubber hard plate and the movable plate rotate up and down. When the rubber hard plate is close to the surface of the accessory, the rubber hard plate rotates up and down and cooperates with its own characteristics to rotate in the plane of the movable plate so as to better approach the surface of the accessory. When the rubber hard plate rotates up and down, the rubber hard plate is obliquely pressed against the accessory, and the rotating connection between the movable plate and the clamping column can support the accessory at multiple angles. Through the above components, the contact area with the accessory is increased by fitting the accessory surface at multiple angles, avoiding the deviation caused by single-point contact.

[0019] (3) The present invention utilizes the force of the moving arm to move toward the middle, and when the moving arm drives the fixed arm to move toward the middle, the elastic rod at the other end of the moving arm will move toward the outside and enter the groove 1 opened inside the outer frame. Due to its own elasticity, the elastic rod touches the outer wall of the protrusion when it moves, and moves forward to the bottom along the left side of the protrusion in the moving direction, leaving the resistance range of the protrusion. Due to its own elasticity, the elastic rod will return to its own straight direction, thereby entering the fixed groove, preventing the moving arm from moving in the opposite direction to affect the clamping and fixing of the upper end after the motor stops. When the motor starts working, the elastic rod continues to move forward, and moves along the outer wall of the groove 1 so that the elastic rod moves against the outer wall of the groove 1 and falls off the fixed groove. The motor rotates in the opposite direction and leaves the groove 1. Through the above-mentioned components, through the cooperation of each component, the motor can lock the moving arm to a certain extent during operation, so that the upper clamping mechanism is synchronously locked and cannot move left and right, thereby avoiding the loosening of the clamping mechanism after the motor stops, causing the accessories to fall off.

[0020] (4) The fixed arm of the present invention moves towards the middle of the device under the drive of the moving arm. When the clamping column on the clamping mechanism presses against and fits on the outer wall of the fitting, the round wheel rotatably connected to the bottom of the ejector rod moves forward along the chute opened on the outer frame to the protrusion. When the round wheel moves to the front protrusion of the chute, it drives the ejector rod to move upward along the second housing, and the ejector rod connected to the other side on the fixator moves downward, thereby causing the fixator to rotate towards one end. When the fixator rotates, the second chute opened on the fixator drives the sliding column to move when rotating, thereby controlling the surrounding fixing plates to move closer to the middle of the fixator. The clamping blocks installed on the fixing plates will closely adhere to the fixing module. Thus, after the clamping column approaches the outer wall of the fitting, the fixing module is clamped and fixed by the clamping blocks, so that the shape of the fitting formed by the clamping column after fixing the fitting is fixed, avoiding affecting the multiple clamping columns during subsequent processing of the fitting and causing it to shake backward and generate gaps. By fixing the fixing module, the spring telescopic rod stops telescoping and maintains a fixed state to reduce the generated shaking. Description of the Drawings

Before use, only the power supply needs to be connected, and the accessories to be clamped are placed on the platform of this device. By combining a number of clamping columns 53, when the motor 21 drives the gear 22 to rotate, the gear 22 drives the two moving arms 23 moving externally, so that the fixed arm 31 moves towards the center.

[0046] The fitting mechanism 5 further includes a clamping column 53 fixedly connected to the outer wall of the fixed module 52 away from the spring telescopic rod 51. The clamping column 53 installed on the fixed arm 31 moves forward. When the clamping column 53 touches the surface of the workpiece, the clamping column 53 will cooperate with multiple clamping columns 53 to closely adhere to the fitting when clamping the fitting. The spring telescopic rod 51 at the rear end of the clamping column 53 causes the lengths of the clamping columns 53 to change, so as to fit different length parts of the fitting, squeeze fittings of different shapes, clamp the outer wall of the fitting by the clamping column 53, and multiple clamping columns 53 make contact and close to the outer walls of different parts of the fitting. According to the shape of the fitting, the multiple clamping columns 53 are squeezed, prompting the spring telescopic rods 51 behind the different clamping columns 53 to retract backward, so that the multiple clamping columns 53 closely adhere to the outer wall of the fitting. According to different fitting appearances, the clamping columns 53 form different lengths. With the cooperation of the above components, according to different fitting appearances, the forces received by the spring telescopic rods 51 are different and the contractions are different, so as to change the surface shape formed by the multiple clamping columns 53 to be consistent with the fitting, so as to clamp and fix different fittings.

[0047] Embodiment 2. Please refer to Figures 1 - 8 , the present invention is an intelligent clamping device for mechanical fittings based on multi-degree-of-freedom adaptive adjustment. On the basis of Embodiment 1, the fitting mechanism 5 further includes a moving plate 54 rotatably connected to the outer wall of the clamping column 53. A rubber hard plate 55 is rotatably connected to the outer wall of the moving plate 54. Using the characteristic of the telescopic length of the clamping column 53, when the clamping column 53 is close to the surface of the workpiece. Through the moving plate 54 and the rubber hard plate 55 rotatably connected to the front end of the clamping column 53, the moving plate 54 rotates in a plane with the clamping column 53, while the rubber hard plate 55 rotates up and down with the moving plate 54. When the rubber hard plate 55 is close to the surface of the fitting, through the up and down rotation of the rubber hard plate 55 and its own characteristics, it cooperates with the plane rotation of the moving plate 54 to better close to the surface of the workpiece. When the rubber hard plate 55 rotates up and down, the rubber hard plate 55 is obliquely close to the fitting, and with the rotational connection between the moving plate 54 and the clamping column 53, it can support at multiple angles. Through the above components, by fitting the surface of the fitting at multiple angles, the contact area with the fitting is increased, and the deviation caused by single-point contact is avoided.

[0048] The coupling mechanism 5 also includes a spring returner 56 fixedly connected to the outer wall of the moving plate 54. One end of the spring returner 56 away from the moving plate 54 is fixedly connected to the inner wall of the rubber hard plate 55. A slot mechanism 6 is provided on the inner wall of the outer frame 1. The fixed arm 31 moves toward the middle of the device under the drive of the moving arm 23. When the clamping column 53 on the clamping mechanism 3 is pressed and fitted on the outer wall of the accessory, the round wheel 38 connected to the bottom of the push rod 37 rotates and moves forward to the protrusion along the slide groove 11 provided on the outer frame 1. When the round wheel 38 moves to the front end protrusion of the slide groove 11, it drives the push rod 37 to move upward along the outer shell 34, and the push rod 37 on the other side connected to the fixer 35 moves downward, so that the fixer 37 The fixer 35 rotates to one end. When the fixer 35 rotates, the slide groove 41 provided on the fixer 35 rotates, which will drive the slide column 43 to move, thereby controlling the surrounding fixed plates 42 to move closer to the middle of the fixer 35. The clamping block 44 installed on the fixed plate 42 will be close to the fixed module 52, so that the clamping column 53 is close to the outer wall of the accessory, and the fixed module 52 is clamped and fixed by the clamping block 44, so that the shape of the accessory formed by the clamping column 53 after the accessory is fixed is fixed, so as to avoid the subsequent processing of the accessory to affect the multiple clamping columns 53 and cause it to shake backward and produce a gap. By fixing the fixed module 52, the spring telescopic rod 51 stops telescoping and keeps in a fixed state to reduce the shaking.

[0049] The card slot mechanism 6 includes a groove 61 fixedly connected to the inner wall of the outer frame 1, a protrusion 62 is fixedly connected to the inside of the groove 61, the inside of the groove 61 is slidably connected to the outer wall of the elastic rod 24, and a fixed groove 63 is provided on the outer wall of the protrusion 62. By utilizing the force of the moving arm 23, when the moving arm 23 drives the fixed arm 31 to move toward the middle, the elastic rod 24 at the other end of the moving arm 23 will move toward the outer end and enter the groove 61 provided inside the outer frame 1. Due to its own elasticity, the elastic rod 24 touches the outer wall of the protrusion 62 when it moves, and moves forward to the bottom along the left side of the protrusion 62 along the moving direction, leaving the resistance of the protrusion 62. The elastic rod 24 can move along the outer wall of the groove 61 to fall off the fixed groove 63, and the motor rotates in the opposite direction to leave the groove 61. Through the above components, the motor can lock the movable arm 23 to a certain extent during operation, so that the upper clamping mechanism 3 can be locked synchronously and cannot move left and right, thereby avoiding the loosening of the clamping mechanism 3 after the motor stops and causing the accessories to fall off.

[0050] A specific application of this embodiment is as follows: A transmission mechanism 2 and a clamping mechanism 3 are provided inside the device. Before use, only the power supply needs to be turned on, and the accessories to be clamped are placed on the platform of the device. The clamping columns 53 are combined together. When the motor 21 drives the gear 22 to rotate, the gear 22 drives the two moving arms 23 moving externally, so that the fixed arm 31 moves towards the center, driving the clamping columns 53 mounted on the fixed arm 31 to move forward. When the clamping columns 53 contact the surface of the workpiece, the clamping columns 53 will cooperate with multiple clamping columns 53 to closely adhere to the accessories when clamping the accessories. The spring telescopic rods 51 at the rear ends of the clamping columns 53 cause the lengths of the respective clamping columns 53 to change, so as to fit the different length parts of the accessories, squeeze the accessories of different shapes, clamp the outer wall of the accessories by the clamping columns 53, and multiple clamping columns 53 make contact and close to the outer walls of different parts of the accessories. According to the shape of the accessories, multiple clamping columns 53 are squeezed, prompting the spring telescopic rods 51 behind the different clamping columns 53 to retract backward, so that multiple clamping columns 53 closely adhere to the outer wall of the accessories. According to different accessory appearances, the clamping columns 53 form different lengths. Through the cooperation of the above components, according to different accessory appearances, the forces received by the spring telescopic rods 51 are different and the contractions are different, so as to change the surface shape formed by multiple clamping columns 53 to be consistent with the accessories, thereby clamping and fixing different accessories.

[0051] Utilizing the characteristics of the telescopic length of the above clamping columns 53, when the clamping columns 53 are close to the surface of the workpiece. Through the moving plate 54 and the rubber hard plate 55 rotatably connected to the front end of the clamping column 53, the moving plate 54 rotates in a plane with the clamping column 53, and the rubber hard plate 55 rotates up and down with the moving plate 54. When the rubber hard plate 55 is close to the surface of the accessory, through the up and down rotation of the rubber hard plate 55 and its own characteristics, it cooperates with the plane rotation of the moving plate 54 to better adhere to the surface of the workpiece. When the rubber hard plate 55 rotates up and down, the rubber hard plate 55 is obliquely adhered to the accessory, and the rotatable connection between the moving plate 54 and the clamping column 53 can support at multiple angles. Through the above components, by conforming to the surface of the accessory at multiple angles, the contact area with the accessory is increased, avoiding the deviation caused by single-point contact.

[0052] By utilizing the force of the moving arm 23, when the moving arm 23 drives the fixed arm 31 to move toward the middle, the elastic rod 24 at the other end of the moving arm 23 will move toward the outside and enter the groove 61 opened inside the outer frame 1. Due to its own elasticity, the elastic rod 24 touches the outer wall of the protrusion 62 when it moves, and moves forward to the bottom along the left side of the protrusion 62 along the moving direction, leaving the resistance range of the protrusion 62. Due to its own elasticity, the elastic rod 24 will return to its own straight direction, thereby entering the fixed groove 63 to prevent the motor from stopping. After that, the movable arm 23 moves in the opposite direction to affect the clamping and fixing of the upper end. When the motor starts working, the elastic rod 24 continues to move forward, and the elastic rod 24 moves along the outer wall of the groove 61 through the outer wall of the groove 61, thereby falling off the fixed groove 63, and the motor rotates in the opposite direction to leave the groove 61. Through the above components, through the cooperation of each component, the motor can lock the movable arm 23 to a certain extent during operation, so that the upper clamping mechanism 3 is synchronously locked and cannot move left and right, thereby avoiding the loosening of the clamping mechanism 3 caused by the stop of the motor and causing the accessories to fall off.

[0053] The fixed arm 31 moves toward the middle of the device under the drive of the movable arm 23. When the clamping column 53 on the clamping mechanism 3 is pressed and fitted on the outer wall of the accessory, the round wheel 38 connected to the bottom of the push rod 37 rotates and moves forward along the slide groove 11 opened on the outer frame 1 to the protrusion. When the round wheel 38 moves to the front end protrusion of the slide groove 11, the push rod 37 is driven to move upward along the outer shell 2 34, and the push rod 37 connected to the other side of the fixer 35 moves downward, so that the fixer 35 rotates to one end. When the fixer 35 rotates, the slide groove 2 41 opened on the fixer 35 rotates to drive The sliding column 43 moves to control the surrounding fixing plates 42 to move closer to the middle of the fixing device 35. The clamping block 44 installed on the fixing plate 42 will be close to the fixing module 52, so that after the clamping column 53 is close to the outer wall of the accessory, the fixing module 52 is tightened and fixed by the clamping block 44, so that the shape of the accessory formed by the clamping column 53 after the accessory is fixed is fixed, so as to avoid the influence of the multiple clamping columns 53 on the subsequent processing of the accessory, causing it to shake backward and produce a gap. By fixing the fixing module 52, the spring telescopic rod 51 stops telescoping and keeps in a fixed state to reduce the shaking.
