Description

Technical Field

[0001] The invention relates to the technical field of welding and polishing, and in particular to an integrated automatic polishing and welding device for mechanical parts. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

[0003] In the processing of mechanical parts, it is often necessary to weld the parts. When welding, weld scars and excess material often appear at the welding position of the parts. In order to improve the accuracy and aesthetics of the parts, the welding position of the parts needs to be polished to keep the outer surface of the parts smooth.

[0004] There are often rod-shaped parts in mechanical parts. If such parts are welded by arc welding, argon arc welding or other welding methods, the connection point is on the outer surface of the parts and the inside cannot be welded. In order to improve the reliability of welding of rod-shaped parts, friction welding is often used to completely weld the cross-section of the rod-shaped parts together.

[0005] The existing process is to grind with angle grinders, sandpaper, sanding plates and other devices after welding. Welding and grinding are separate, which reduces the efficiency of parts processing. Especially when friction welding is performed, the welding will generate a lot of heat due to friction, and the welding position is prone to bulge outward. The bulge is not an ordinary welding shell, but the same material as the parts, which is relatively difficult to clean.

[0006] To this end, the present application proposes an integrated automated grinding and welding device for mechanical parts, which automatically grinds the welding position of parts during friction welding without the need for transfer, thereby improving the efficiency of welding grinding.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0062] like Figure 1-Figure 10 As shown, the present invention provides an integrated automatic grinding and welding device for mechanical parts, including: a support mechanism 1, a feeding mechanism 2, a transmission mechanism 3, a grinding mechanism 4 and an electrical box 5. The support mechanism 1 is the base of the entire device and plays a supporting role; the feeding mechanism 2 is used to clamp a part of the mechanical parts to be welded and move horizontally; the transmission mechanism 3 is used to clamp and drive another part of the mechanical parts to be welded to rotate; the grinding mechanism 4 is used to grind the welding position of the mechanical parts after welding; the electrical box 5 is used to issue work instructions to the feeding mechanism 2, the transmission mechanism 3 and the grinding mechanism 4 respectively. According to processing needs, a hydraulic cylinder and controller and / or an electric push rod controller, a PLC module, a human-computer interaction module and a timing and delay module can be set inside the electrical box 5. Among them, the hydraulic cylinder and controller, the electric push rod controller are used one or in combination as needed to drive the feeding mechanism 2, the clamping of the transmission mechanism 3 and the rotation of the grinding mechanism 4. The PLC module is used to control the displacement of the feeding mechanism 2, the rotation of the mechanical parts driven by the transmission mechanism 3, etc. The human-computer interaction module is used to receive, retrieve and output the instructions set by the operator. The timing and delay modules are divided into two parts. The timing module can be used to set the timing switch of the equipment. The delay module is used to play a buffer protection role when the equipment is working, avoiding the equipment from being started or stopped quickly and causing the equipment life to be reduced.

[0063] Specifically, the feeding mechanism 2, the transmission mechanism 3 and the grinding mechanism 4 are all arranged on the top of the support mechanism 1. The feeding mechanism 2 and the transmission mechanism 3 are respectively located on the left and right sides of the top of the support mechanism 1, and are used to fix two mechanical parts to be welded. The grinding mechanism 4 is located between the feeding mechanism 2 and the transmission mechanism 3. After the mechanical parts are welded, the transmission mechanism 3 mechanically drives the mechanical parts to rotate, and the grinding mechanism 4 rotates at an angle and contacts the outer surface of the high-speed rotating mechanical parts to grind the welding position of the mechanical parts.

[0064] The electrical box 5 is arranged inside the supporting mechanism 1, and the lines of the feeding mechanism 2, the transmission mechanism 3 and the grinding mechanism 4 are all led to the inside of the electrical box 5. When working, the electrical box 5 is connected to the electrical box 5 through a keyboard, a PC device, a host computer and other devices, and all driving components can be controlled through the electrical box 5.

[0065] like Figure 2 As shown, in some embodiments, the support mechanism 1 of the present invention includes a support electrical cabinet 101, the interior of the support electrical cabinet 101 is configured as a cavity for placing various electrical devices, control units and line layouts. A processing table 102 is provided on the top of the support electrical cabinet 101, which is used to close the top of the support electrical cabinet 101 to form a table for processing mechanical parts.

[0066] A limited slide groove 103 is provided on one side of the top of the processing table 102 to form a horizontal moving track. A slide bar supporting the feeding mechanism 2 is provided in the middle of the limited slide groove 103. The feeding mechanism 2 is installed inside the limited slide groove 103 and can slide horizontally, thereby driving the horizontal movement of the mechanical parts to be welded.

[0067] like Figure 1-Figure 3 As shown, in some embodiments, a fixed support frame 104 and a movable support frame 105 are respectively provided on the top of the processing table 102 of the present invention. The fixed support frame 104 is located between the limiting slide groove 103 and the grinding mechanism 4, and the movable support frame 105 is located on the left side of the transmission mechanism 3. When welding mechanical parts, the fixed support frame 104 is used to support the end of the mechanical parts driven by the feeding mechanism 2, and the movable support frame 105 is used to support the tail of the mechanical parts clamped by the transmission mechanism 3. By supporting the mechanical parts on both sides, it is avoided that the mechanical parts cause pressure on the feeding mechanism 2 and the transmission mechanism 3 respectively due to being suspended. Among them, the movable support frame 105 is fixed to the top of the processing table 102 with bolts, and the installation position of the movable support frame 105 can be adjusted according to the length of the mechanical parts for adaptation.

[0068] The tops of the fixed support frame 104 and the movable support frame 105 are provided with limiting grooves, which are used to limit the mechanical parts and reduce the possibility of the mechanical parts being separated from the fixed support frame 104 and the movable support frame 105. Rollers 106 are evenly installed inside all the limiting grooves. When grinding the mechanical parts, the rollers 106 can reduce the friction between the mechanical parts and the limiting grooves, and are used to protect the fixed support frame 104, the movable support frame 105 and the mechanical parts respectively.

[0069] like Figure 1-Figure 2 As shown, in some embodiments, the feeding mechanism 2 of the present invention includes a linear motor platform 201, and a linear motor is arranged at the bottom of the linear motor platform 201. The linear motor is installed inside the limiting slide groove 103, and the linear motor drives the linear motor platform 201 to move horizontally, thereby achieving the effect of driving the mechanical parts to apply pressure to the transmission mechanism 3.

[0070] The top of the linear motor platform 201 is respectively provided with a tail bracket 202 and a movable clamping part 203. The tail bracket 202 can support mechanical parts, and the movable clamping part 203 can clamp and fix the mechanical parts. The tail bracket 202 can keep the mechanical parts stable after being clamped by the movable clamping part 203. The movable clamping part 203 has two states when clamping the mechanical parts. State one is tight clamping, which keeps the mechanical parts completely positioned and still. State two is loose clamping, in which the mechanical parts are in a semi-clamping state and can rotate under the action of torque. This state is only to prevent the mechanical parts from detaching. The above two states correspond to two processing processes, which are completely fixed during friction welding and semi-clamping during grinding.

[0071] A flexible wire trough chain 204 is provided at the bottom of the linear motor platform 201, and the flexible wire trough chain 204 extends to the inside of the electrical box 5. The power drive lines of the linear motor and the transmission mechanism 3 pass through the inside of the flexible wire trough chain 204 and enter the electrical box 5.

[0072] like Figure 1As shown, in some embodiments, the movable clamping part 203 of the present invention includes a connecting flange 2031, and the connecting flange 2031 is fixed on the top of the processing table 102. The axis of the connecting flange 2031 is provided with a hollow sleeve extending to the inside of the supporting electrical cabinet 101, and the axis core sleeve of the connecting flange 2031 is provided with a telescopic rod 2032 that can be telescoped up and down, and the telescopic rod 2032 is one of an electric push rod, a hydraulic push rod or a pneumatic push rod. Both sides of the top of the connecting flange 2031 are hinged with fixed clamps 2033, and the clamping and loosening operations are realized by changing the angle between the two fixed clamps 2033. The upper end of the telescopic rod 2032 is hinged with the middle part of the fixed clamp 2033 through a connecting rod. When the telescopic rod 2032 rises to the level of the connecting rods on both sides, the two fixed clamps 2033 are at the maximum opening angle. When the telescopic rod 2032 descends, the fixing clamp 2033 is pulled toward the middle through the connecting rod, so that the space between the two fixing clamps 2033 is contracted for clamping mechanical parts.

[0073] It should be noted that the top of the inner wall of the two side fixing clamps 2033 is provided with opposite limiting rollers 2034. When the fixing clamps 2033 are in a semi-clamping state, the limiting rollers 2034 will contact the outer surface of the mechanical parts, and when the mechanical parts rotate at high speed, the limiting rollers 2034 can relatively reduce the friction.

[0074] To facilitate wiring, Figure 4-Figure 5 As shown, a wiring compartment 2011 is provided inside the linear motor platform 201 of the present invention for wiring. A sealing cover 2012 is provided at the bottom of the linear motor platform 201. The sealing cover 2012 can be opened for convenient threading. The sealing cover 2012 is provided with a wire outlet hole 2013 that is connected to the wiring compartment 2011, and the line can be led out through the wire outlet hole 2013.

[0075] The sealing cover 2012 is fixedly connected to the end of the flexible wire trough chain 204 by bolts, and the sealing cover 2012 and the flexible wire trough chain 204 can be easily separated during maintenance. The outlet hole 2013 is connected to the flexible wire trough chain 204, and the control line of the telescopic rod 2032 passes through the outlet hole 2013 to the inside of the flexible wire trough chain 204, so that the line can enter the electrical box 5 through the inside of the flexible wire trough chain 204.

[0076] like Figure 2-Figure 3 , Figure 6As shown, in some embodiments, the transmission mechanism 3 of the present invention includes a connecting flange 2 301, which is fixed on the top of the processing table 102, and a retractable telescopic rod 2 302 is arranged on the axis of the connecting flange 2 301. A fixed clamp 2 303 is hinged on both sides of the top of the connecting flange 2 301, and the upper part of the telescopic rod 2 302 is hinged to the middle part of the fixed clamp 2 303 through a connecting rod, and a limited roller 2 304 is arranged on the facing surface of the top of the fixed clamp 2 303. This part has basically the same structure as the movable clamping part 203, and both are used to clamp the mechanical parts to be welded, but the clamping force of the fixed clamp 2 303 is smaller than that of the movable clamping part 203, and it is always in a semi-clamping state.

[0077] A driving motor 305 is arranged at the top of the telescopic rod 302, and a driving roller 306 is driven at the top of the driving motor 305. This structure is the core structure of the transmission mechanism 3. When the mechanical parts are clamped by the fixing clamp 303, the outer surface of the rod-shaped mechanical parts overlaps with the limiting roller 304 and the driving roller 306 respectively. When the driving motor 305 drives the driving roller 306 to rotate at a high speed, the driving roller 306 will drive the mechanical parts to rotate at a high speed under the action of friction. At this time, a large amount of friction will be generated between the two mechanical parts to achieve friction welding. The driving motor 305 in the attached figure is a simple representation. It is actually a driving device with a motor inside, and the driving roller 306 is driven by the motor.

[0078] It should be noted that the circuit of the drive motor 305 extends from the central axis cavity of the telescopic rod 2 302 into the interior of the supporting electrical cabinet 101 and is connected to the electrical box 5 , so that the drive motor 305 can be controlled by the electrical components in the electrical box 5 .

[0079] like Figure 1-Figure 2 , Figure 7-10As shown, in some embodiments, the grinding mechanism 4 of the present invention includes a grinding traction plate 401, the lower end of which is hinged to the top of the processing table 102, so that the grinding traction plate 401 can rotate with the hinge point as the axis. A traction rod 402 is provided at the connection between the grinding traction plate 401 and the processing table 102 to drive the grinding traction plate 401 to rotate along the hinge. The traction rod 402 is an electric, pneumatic or hydraulic telescopic rod 2032, and its two ends are respectively hinged to the grinding traction plate 401 and the processing table 102. When the traction rod 402 is extended, the grinding traction plate 401 is away from the mechanical parts and is in a state to be welded. When the traction rod 402 is retracted, the grinding traction plate 401 approaches the direction of the mechanical parts, and then enters the grinding state. The line of the traction rod 402 is led to the inside of the electrical box 5, so that the rotation of the grinding traction plate 401 is also controlled by the components inside the electrical box 5, realizing control integration. A grinding head 403 is arranged on the side of the grinding traction plate 401 facing the mechanical parts. The side of the grinding head 403 facing the mechanical parts is a rough surface, and the roughness is configured according to the grinding needs.

[0080] like Fig. 9 and 10 As shown, in some embodiments, a mounting groove 4011 is provided at the connection between the grinding traction plate 401 and the grinding head 403 of the present invention, and the grinding head 403 is located inside the mounting groove 4011 and fixed by bolts.

[0081] Through the above technical solution, the grinding head 403 can be easily disassembled and replaced, so that the easily damaged grinding head 403 can be maintained, and the grinding head 403 with different grinding meshes can be replaced according to different roughness requirements of parts, thereby improving the convenience and adaptability of use.

[0082] like Figure 8-Figure 10 As shown, in some embodiments, the inner wall of the mounting groove 4011 of the present invention is provided with an air inlet 4012, and the bottom of the grinding traction plate 401 is provided with an air outlet 4013, and the air inlet 4012 and the air outlet 4013 are interconnected to allow solid and gas to pass through. A dust suction device is provided inside the electrical box 5, and the pipeline of the dust suction device enters from the air outlet 4013 to the inside of the grinding traction plate 401 and communicates with the air inlet 4012.

[0083] An air connection pipe 4031 is provided on the top of the grinding head 403, and the air connection pipe 4031 is used to be inserted into the interior of the air inlet 4012 to achieve the connection of the channel. A grinding head 4032 is provided on the side of the grinding head 403 away from the air connection pipe 4031, and the grinding head 4032 is used to achieve the purpose of grinding, and its roughness is adapted according to actual needs. A plurality of air inlet grooves 4033 are equidistantly provided on the grinding head 4032, and the air inlet grooves 4033 are connected to the air connection pipe 4031. During the grinding process, the debris generated by the friction between the grinding head 4032 and the mechanical parts will be sucked in through the air inlet grooves 4033. It prevents the debris from spreading in the air, improves the environmental protection degree, and the metal debris can be collected and further processed, generating new economic benefits.

[0084] The specific use process of the present invention is as follows:

[0085] Pre-adjust the installation position of the movable support frame 105 to adapt to the length of the mechanical parts to be welded;

[0086] Place the two mechanical parts to be welded between the movable clamping part 203 and the second fixed clamp 303 respectively, and make the end of the mechanical part on the side of the transmission mechanism 3 overlap with the grinding traction plate 401, and make the end of the mechanical part on one end of the feeding mechanism 2 exceed the fixed support frame 104;

[0087] The electrical box 5 controls the fixing clamp 2033 and the fixing clamp 2 303 to clamp the mechanical parts respectively;

[0088] The linear motor platform 201 is controlled by the electrical box 5 to move in the direction of the transmission mechanism 3, so that the ends of the two mechanical parts contact each other, and the linear motor platform 201 continues to push the mechanical parts to apply pressure;

[0089] The driving motor 305 is started through the electrical box 5, and the mechanical parts on one side are driven to rotate at high speed through the driving roller 306 under the action of friction force, so that the two mechanical parts rub violently to achieve friction welding;

[0090] After welding is completed, the movable clamping part 203 slightly loosens the mechanical parts, and the driving motor 305 continues to drive the integrated mechanical parts to rotate;

[0091] The traction rod 402 is controlled by the electrical box 5, so that the grinding head 403 on the grinding traction plate 401 overlaps with the welding part of the mechanical parts, and the welding part of the mechanical parts is ground under the power of high rotation;

[0092] At the same time, the dust collecting device in the electrical box 5 works to collect the generated debris through the air inlet slot 4033;

[0093] After the grinding is completed, the grinding traction plate 401 returns to the initial state, and the movable clamping part 203 and the second fixing clamp 303 release the mechanical parts to complete the processing.

[0094] In summary, the integrated equipment for automated grinding and welding of mechanical parts of the present invention clamps the rod-shaped parts to be welded by respectively setting a feeding mechanism 2 and a transmission mechanism 3, and drives the rod-shaped mechanical parts to move in the direction of the transmission mechanism 3 through the feeding mechanism 2 to overlap the two rod-shaped parts. Subsequently, the transmission mechanism 3 drives one of the rod-shaped mechanical parts to rotate at high speed, and the feeding mechanism 2 mechanically applies pressure to the other mechanical part, thereby welding is performed by frictional heating. After welding is completed, the feeding mechanism 2 slightly loosens the clamping force on the mechanical parts, and drives the welded mechanical parts to continue to rotate through the transmission mechanism 3. At this time, the end of the grinding mechanism 4 rotates and overlaps the welding point of the mechanical parts to grind the rotating mechanical parts, thereby achieving the effect of integrated welding and grinding, and realizing the effect of improving welding and grinding efficiency.

[0095] By respectively arranging a fixed support frame 104 and a movable support frame 105 on the top of the processing table 102, and arranging a tail bracket 202 on the top of the linear motor platform 201, when the movable clamping part 203 and the transmission mechanism 3 clamp the mechanical parts, the arranged fixed support frame 104, the movable support frame 105 and the tail bracket 202 can play an auxiliary supporting role for the overly long mechanical parts, thereby improving the clamping stability of the movable clamping part 203 and the transmission mechanism 3.

[0096] By providing a mounting groove 4011 on the wall surface of the grinding traction plate 401 and fixing the grinding head 403 through the cooperation of the mounting groove 4011 and the bolt, the grinding head 403 of the wearing part can be conveniently replaced, thereby improving the convenience of use.

[0097] By arranging an air inlet hole 4012 inside the installation groove 4011 and an air outlet hole 4013 at the bottom of the grinding traction plate 401, and connecting the air inlet hole 4012 to the dust suction device, and at the same time arranging an air connecting pipe 4031 on the grinding head 403 to be plugged into the air inlet hole 4012, and arranging an air inlet groove 4033 on the surface of the grinding head 403 facing the mechanical parts, the metal debris generated during grinding can be collected by the dust suction device to improve the cleanliness of the equipment.

[0098] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
