Description

Technical Field

[0001] This invention relates to a clamping structure for a robot welding mold, and more particularly to an integral clamping frame structure for a robot welding mold, belonging to the field of robot welding technology. Background Technology

[0002] With rapid socio-economic development, modern automobiles are constantly being updated and replaced by newer models, leading to their discontinuation. This has resulted in the obsolescence of welding equipment and molds used for welding interior parts of older models, increasing production costs for various manufacturers.

[0003] To reduce production costs, manufacturers are increasingly investing in flexible welding equipment. By changing different molds, different products can be welded. Since molds are relatively inexpensive, simply replacing the molds can control costs. Among these efforts, robots are increasingly being used in product welding equipment.

[0004] In the welding process of robots, when encountering large products with different angles at various welding points, requiring the robot's welding head to change angles during welding, the traditional single-cylinder flipping and clamping method reveals some drawbacks:

[0005] (1) When the product is large, the traditional single cylinder clamping cannot clamp the inside of the product better (the clamping lever arm is long and the clamping force is insufficient), resulting in unsatisfactory welding effect or even scrapping.

[0006] (2) Traditional single-cylinder clamping has insufficient clamping force due to the existence of the fit clearance between the parts;

[0007] (3) When the angle of the product welding point is different, the robot needs to change the angle. The traditional pressing method needs to avoid the robot welding mechanism. When encountering complex products, the pressing position interferes with the welding mechanism and cannot be pressed, which will also affect the welding effect. Adjusting the pressing position is inconvenient. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of the prior art, such as insufficient pressure, complex operation, and low efficiency, by providing a robotic welding mold integral pressure frame clamping structure that can achieve constant and lasting pressure and high efficiency.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: a robot welding mold integral pressing frame clamping structure, used to press the plastic welding product as a whole during welding, including an electronic control device and a grating protection device. The electronic control device is set on one side of the robot welding mold integral pressing frame clamping structure, and a clamping button is provided inside the electronic control device. The grating protection device is set around the robot welding mold integral pressing frame clamping structure.

[0010] It also includes a left structure, a right structure, a main connecting rod, a pressure frame, and several pressure heads. The left structure includes a left pressure frame opening and closing structure, a left pressure frame anti-fall structure, a left support seat, a left buffer limiting structure, and a left pressure frame locking structure. The right structure includes a right pressure frame opening and closing structure, a right pressure frame anti-fall structure, a right support seat, a right buffer limiting structure, and a right pressure frame locking structure. The left and right structures are symmetrically arranged on the left and right sides. The left pressure frame opening and closing structure, left pressure frame anti-fall structure, left support seat, left pressure frame locking structure, and left buffer limiting structure are symmetrically arranged on the left and right sides, respectively, with the right pressure frame opening and closing structure, right pressure frame anti-fall structure, right support seat, right pressure frame locking structure, and right buffer limiting structure. The pressure frame body is provided with a transverse groove, and one pressure frame fixing seat is provided on each of the two front ends of the pressure frame.

[0011] The pressure head includes a connecting and fixing plate, a nut, and a polyurethane pressure head. The connecting and fixing plate is an integral structure, including a pressure frame connecting part and a pressure head connecting part. The pressure frame connecting part is fixedly connected to the pressure frame, and the pressure head connecting part is fixedly connected to the polyurethane pressure head.

[0012] Both ends of the main connecting rod are rounded;

[0013] In the left structure: the left pressure frame opening and closing structure includes a pressure frame connector, a cylinder fixing seat, a pressure frame cylinder, pin A, a fisheye connector, pin B, and a connecting block;

[0014] The pressure frame connector is an integral structure, including a pressure frame connecting rod and a pressure frame cylinder connecting rod. The pressure frame connecting rod and the pressure frame cylinder connecting rod are arranged at an angle, and the included angle between the pressure frame connecting rod and the pressure frame cylinder connecting rod is 115-125°. A main connecting rod positioning hole is provided between the pressure frame connecting rod and the pressure frame cylinder connecting rod, and a pin B connecting hole is provided at the lower end of the pressure frame cylinder connecting rod.

[0015] The pressure frame connecting rod is provided with several pressure frame connecting holes, and the pressure frame connecting rod and the pressure frame are fixedly connected by pins through the pressure frame connecting holes;

[0016] The bottom of the cylinder mounting base is fixed to the ground with screws, and the rear end of the frame pressing cylinder is connected to the upper end of the cylinder mounting base with pin A; one end of the fisheye connector is fixedly connected to the front end of the cylinder rod of the frame pressing cylinder, and the other end is provided with a pin B through hole. The pin B passes through the connecting block, the pin B through hole and the pin B connecting hole in sequence to connect the connecting block, the fisheye connector and the frame pressing cylinder connecting rod together, forming a rotating connection between the frame pressing cylinder connecting rod and the frame pressing cylinder;

[0017] When the connecting rod of the frame pressing cylinder is pulled, the connecting rod of the frame pressing cylinder moves in a circular motion around the frame pressing connection hole, and the pin B connection hole follows an arc. When the frame pressing cylinder moves in a telescopic motion, the frame pressing cylinder does not move completely horizontally. The pin B through hole of the fisheye joint follows an arc with the pin B connection hole. The frame pressing cylinder and the fisheye joint rotate around the pin A as the cylinder rod of the frame pressing cylinder extends and retracts.

[0018] The left pressure frame anti-fall structure is located on the right inner side of the left pressure frame opening and closing structure. The left pressure frame anti-fall structure includes an anti-fall fixing seat, a copper sleeve, an anti-fall locking pin, and an anti-fall cylinder. The bottom of the anti-fall fixing seat is fixed to the ground with screws. The upper part of the anti-fall fixing seat is provided with an installation hole. The copper sleeve is fixedly installed in the installation hole. The anti-fall locking pin is installed in the copper sleeve and is clearance-fitted with each other. The rear end of the anti-fall locking pin is fixedly connected to the front end of the cylinder rod of the anti-fall cylinder. When the cylinder rod of the anti-fall cylinder retracts, the anti-fall locking pin retracts into the copper sleeve. When the cylinder rod of the anti-fall cylinder extends forward, the front end of the anti-fall locking pin extends forward from the installation hole, blocking the pressure frame cylinder connecting rod from continuing to fall, thus preventing the pressure frame from continuing to fall.

[0019] The left support is positioned above the anti-fall fixing seat, and the bottom of the left support is fixedly connected to the upper end of the anti-fall fixing seat with screws. The upper part of the left support is a bearing seat, and the bearing seat has a bearing hole in the middle. It also includes a retaining ring, which is positioned between the bearing hole and the positioning hole of the main connecting rod. The positioning hole of the main connecting rod is a segmental hole. The left end of the main connecting rod passes through the bearing hole and the retaining ring in sequence and then inserts into the positioning hole. The platform of the segmental end of the main connecting rod fits the plane of the segmental hole, so that the main connecting rod and the pressure frame connector are fixedly connected as one unit.

[0020] When the frame pressing cylinder is activated, and the cylinder rod of the frame pressing cylinder retracts horizontally, the connecting rod of the frame pressing cylinder rotates around pin B and pulls towards the frame pressing cylinder. The frame pressing connector rotates together with the main connecting rod around the main connecting rod, causing the frame pressing connector to drive the frame pressing upward. Conversely, when the frame pressing cylinder is activated, and the cylinder rod of the frame pressing cylinder extends forward horizontally, the connecting rod of the frame pressing cylinder moves away from the direction of the frame pressing cylinder, causing the frame pressing connector to drive the frame pressing downward, returning to the initial state.

[0021] The left buffer limiting structure is located in front of the cylinder fixing seat, and the bottom of the left buffer limiting structure is fixed to the ground with screws. When the pressure frame falls to a horizontal position, the bottom of the pressure frame fixing seat on the left side of the pressure frame presses on the upper end of the left buffer limiting structure, and the left buffer limiting structure plays a buffering role.

[0022] The left pressure frame locking structure is located in front of the left buffer limiting structure. The left pressure frame locking structure includes a locking fixing block, a locking cylinder, and a locking block. The bottom of the locking fixing block is fixed to the ground with screws. The locking cylinder is fixedly located above the locking fixing block. The locking block is fixedly connected to the upper end of the cylinder rod of the locking cylinder. A locking protrusion is provided on one side of the upper end of the locking block. First, manually rotate the locking protrusion 90 degrees. Then, when the pressure frame moves in an arc and presses down, manually rotate the locking protrusion back 90 degrees so that the locking protrusion presses against the bottom plate of the pressure frame fixing seat and locks the pressure frame.

[0023] The right-hand structure is exactly the same as the left-hand structure in terms of specific structure, but the left and right directions are opposite.

[0024] Action flow:

[0025] During operation, the employee places the plastic welding product, clicks the clamp button, activates the light curtain protection, retracts the left and right pressure frame anti-fall cylinders, and extends the cylinder rods of the left and right pressure frame cylinders, driving the left and right pressure frame connecting rods to rotate. During the rotation and pressing of the pressure frame, the left and right buffer limit structure buffer device acts to reduce the impact force. After the pressure frame is pressed down to the clamping position, the locking cylinder locks it, increasing the clamping force.

[0026] After the robot finishes welding, it returns to its original position. The left and right pressure frame locking cylinders open, the pressure frame cylinders retract, and the pressure frame connecting rod rotates and rises. After the pressure frame rises to the correct position, the pressure frame anti-fall cylinder opens, and the anti-fall locking pin extends to block the pressure frame cylinder connecting rod, preventing the pressure frame from falling.

[0027] There are a total of 28 pressure heads, which are evenly arranged in 4 rows and fixed on the crossbeam of the pressure frame; the number and spacing of the pressure heads can be adjusted according to the number of molds being pressed.

[0028] The pressure head has a longitudinal guide hole on its pressure frame connection part. The pressure head is fixedly connected to the pressure frame by screws passing through the longitudinal guide hole. The pressure head can be adjusted longitudinally through the longitudinal guide hole to meet the height requirements of the mold position. The pressure head is fixed in the aluminum profile groove. The position of the clamping point can be adjusted at will according to the usage. The clamping force of each clamping point can be adjusted individually.

[0029] It also includes two stops, with one platform on each side of the main connecting rod. The two stops are respectively set on the platforms on both sides of the main connecting rod and fastened with screws, which restricts the main connecting rod from moving to the left and right bearing holes, ensuring the smooth rotation of the pressure frame.

[0030] Each pressure frame connecting rod has 4 pressure frame connecting holes.

[0031] The pressure head connection part is provided with a screw hole, and the upper end of the polyurethane pressure head is provided with a thread. The upper end of the polyurethane pressure head passes through the screw hole, and the pressure head connection part and the polyurethane pressure head are fixedly connected by a nut and the thread at the upper end of the polyurethane pressure head.

[0032] The included angle between the pressure frame connecting rod and the pressure frame cylinder connecting rod is 120°.

[0033] The pressure frame is made of aluminum alloy.

[0034] Compared with the prior art, the beneficial effects of the present invention are: in order to solve the drawbacks of traditional single cylinder clamping, this patent applies an integral clamping frame structure based on robot welding.

[0035] (1) The overall clamping force is large, which is suitable for clamping larger products and can better clamp the inside of the product and improve the welding effect;

[0036] (2) The left and right structures are symmetrically arranged, the equipment operates stably, and the plastic welding products are pressed firmly as a whole to ensure welding quality;

[0037] (3) The pressure head is fixed in the aluminum profile groove, and the position of the pressure point can be adjusted at will according to the usage. The pressure force of each pressure point can be adjusted individually.

The pressure frame connecting part 501A is fixedly connected to the pressure frame 4, and the pressure head connecting part 501B is fixedly connected to the polyurethane pressure head 503.

[0060] like Figure 6 , Figure 7 As shown, both ends of the main connecting rod 3 are chamfered.

[0061] In the left-side structure 1: as follows Figure 8 , Figure 9 As shown, the left pressure frame opening and closing structure 101 includes a pressure frame connector 10101, a cylinder fixing seat 10102, a pressure frame cylinder 10103, a pin A 10104, a fisheye connector 10105, a pin B 10106, and a connecting block 10107.

[0062] like Figure 9 , Figure 10As shown, the frame pressing connector 10101 is an integral structure, including a frame pressing connecting rod 10101A and a frame pressing cylinder connecting rod 10101B. The frame pressing connecting rod 10101A and the frame pressing cylinder connecting rod 10101B are arranged obliquely, and the included angle α between the frame pressing connecting rod 10101A and the frame pressing cylinder connecting rod 10101B is 120°. A positioning hole for the main connecting rod 3 is provided between the frame pressing connecting rod 10101A and the frame pressing cylinder connecting rod 10101B, and a pin shaft B10106 connecting hole is provided at the lower end of the frame pressing cylinder connecting rod 10101B.

[0063] like Figure 4 As shown, the pressure frame connecting rod 10101A is provided with several pressure frame connecting holes 7, and the pressure frame connector 10101 and the pressure frame 4 are fixedly connected by pins through the pressure frame connecting holes 7.

[0064] like Figure 4 , Figure 8 and Figure 9 As shown, the bottom of the cylinder mounting base 10102 is fixed to the ground with screws, and the rear end of the frame pressing cylinder 10103 is connected to the upper end of the cylinder mounting base 10102 with a pin A 10104; one end of the fisheye connector 10105 is fixedly connected to the front end of the cylinder rod of the frame pressing cylinder 10103, and the other end is provided with a pin B 10106 through hole.

[0065] As shown in Figure 9, Figure 13 and Figure 14 As shown, when the frame pressing cylinder connecting rod 10101B is pulled, the frame pressing cylinder connecting rod 10101B moves in a circular motion around the frame pressing connecting hole 7, and the pin B 10106 connecting hole follows an arc. When the frame pressing cylinder 10103 moves in a telescopic motion, the frame pressing cylinder 10103 does not move completely horizontally. The pin B 10106 through hole of the fisheye joint 10105 follows an arc with the pin B 10106 connecting hole. The frame pressing cylinder 10103 and the fisheye joint 10105 rotate around the pin A 10104 as the cylinder rod of the frame pressing cylinder 10103 telescopics.

[0066] like Figure 6 , Figure 11 and Figure 12As shown, the left pressure frame anti-fall structure 102 is located on the right inner side of the left pressure frame opening and closing structure 101. The left pressure frame anti-fall structure 102 includes an anti-fall fixing base 10201, a copper sleeve 10202, an anti-fall locking pin 10203, and an anti-fall cylinder 10204. The bottom of the anti-fall fixing base 10201 is fixed to the ground with screws, and the upper part of the anti-fall fixing base 10201 is provided with a mounting hole. The copper sleeve 10202 is fixedly installed in the mounting hole, and the anti-fall locking pin 10203 is provided with...

When the cylinder rod of the anti-fall cylinder 10204 retracts, the anti-fall locking pin 10203 retracts into the copper sleeve 10202. When the cylinder rod of the anti-fall cylinder 10204 extends forward, the front end of the anti-fall locking pin 10203 extends forward from the mounting hole, blocking the pressure frame cylinder connecting rod 10101B from continuing to fall, which also blocks the pressure frame 4 from continuing to fall.

[0067] like Figure 4 , Figure 7 As shown, the left support seat 103 is positioned above the anti-fall fixing seat 10201, and the bottom of the left support seat 103 is fixedly connected to the upper end of the anti-fall fixing seat 10201 with screws; the upper part of the left support seat 103 is a bearing seat, the bearing seat has a bearing hole in the middle, and also includes a retaining ring, which is positioned between the bearing hole and the positioning hole of the main connecting rod 3; the positioning hole of the main connecting rod 3 is a segmental hole, and the left end of the main connecting rod 3 passes through the bearing hole and the retaining ring in sequence and then inserts into the positioning hole of the main connecting rod 3.

[0068] like Figure 13 , Figure 14 As shown, when the frame pressing cylinder 10103 is started and the cylinder rod of the frame pressing cylinder 10103 moves horizontally and retracts, the frame pressing cylinder connecting rod 10101B rotates around the pin B 10106 and pulls towards the frame pressing cylinder 10103. The frame pressing connector 10101 rotates together with the main connecting rod 3 around the main connecting rod 3, causing the frame pressing connecting rod 10101A to drive the frame pressing 4 to rotate upward. Conversely, when the frame pressing cylinder 10103 is started and the cylinder rod of the frame pressing cylinder 10103 moves horizontally and extends forward, the frame pressing cylinder connecting rod 10101B moves away from the direction of the frame pressing cylinder 10103, and the frame pressing connecting rod 10101A drives the frame pressing 4 to rotate downward and return to the initial state.

[0069] like Figure 3 , Figure 14 and Figure 15As shown, the left buffer limiting structure 104 is located in front of the cylinder fixing seat 10102, and the bottom of the left buffer limiting structure 104 is fixed to the ground with screws; when the pressure frame 4 falls to a horizontal position, the bottom of the pressure frame fixing seat 6 on the left side of the pressure frame 4 presses on the upper end of the left buffer limiting structure 104, and the left buffer limiting structure 104 plays a buffering role.

[0070] like Figure 3 , Figure 15 and Figure 16 As shown, the left pressure frame locking structure 105 is located in front of the left buffer limiting structure 104.

The locking block 10503 is fixedly connected to the upper end of the cylinder rod of the locking cylinder 10502. A locking protrusion 10504 is provided on one side of the upper end of the locking block 10503. First, the locking protrusion 10504 is manually rotated 90 degrees. Then, when the pressure frame 4 moves forward and downward in an arc, the locking protrusion 10504 is manually rotated back 90 degrees so that the locking protrusion 10504 presses against the bottom plate of the pressure frame fixing seat 6 and locks the pressure frame 4.

[0071] like Figures 1 to 16 As shown, the right structure 2 is exactly the same as the left structure 1 in terms of specific structure, but the left and right directions are opposite. Therefore, the specific construction of the right structure 2 will not be described in detail.

[0073] like Figure 13 As shown, during operation, the employee places the plastic welding product, clicks the clamp button, the grating protection is activated, the left and right pressure frame 4 anti-fall cylinders 10204 retract, and the cylinder rods of the left and right pressure frame cylinders 10103 extend, driving the left and right pressure frame connecting rods 10101A to rotate; during the rotation and pressing down of the pressure frame 4, the left and right buffer limit structures 204 buffer device acts to reduce the impact force; after the pressure frame 4 is pressed down to the clamping position, the locking cylinder 10502 locks it, increasing the clamping force;

[0074] like Figure 14 As shown, after the robot completes the welding, it returns to its original position. The locking cylinders 10502 of the left and right pressure frames 4 open, the pressure frame cylinder 10103 retracts, and the pressure frame connecting rod 10101A rotates and rises. After the pressure frame 4 rises to the position, the pressure frame 4 anti-fall cylinder opens, and the anti-fall locking pin 10203 extends to block the pressure frame cylinder connecting rod 10101B, preventing the pressure frame 4 from falling.

[0075] like Figure 4As shown, there are a total of 28 pressure heads 5, which are evenly arranged in 4 rows and fixed on the crossbeam of the pressure frame 4; the number and spacing of the pressure heads 5 can be adjusted according to the number of molds being pressed.

[0076] like Figure 4 As shown, the pressure head 5 has a longitudinal guide hole on the pressure frame connection part 501A. The pressure head 5 is fixedly connected to the pressure frame 4 by screws passing through the longitudinal guide hole. The pressure head 5 can be longitudinally adjusted through the longitudinal guide hole to meet the height requirements of the mold position. The pressure head 5 is fixed in the aluminum profile groove and the position of the pressing point can be adjusted at will according to the usage. The pressing force of each pressing point can be adjusted individually.

[0081] The embodiments described above are merely preferred embodiments of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solutions of the present invention should be included within the protection scope of the present invention.
