Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an induction mechanism for welding clamps. Background Art

[0002] At present, in the production process of automobile parts, the welding process between two parts often requires the assistance of a clamp, which can tighten the parts and then effectively weld the two automobile parts through a welding machine; however, the clamp in the prior art does not have an induction detection function after welding. When a leak occurs, it can only be observed by the naked eye. When the observation is not in place, a lot of time will be wasted (after normal welding, the automobile parts need to be disassembled. If a leak occurs after the automobile parts are disassembled, the parts need to be installed again for welding), which greatly reduces production efficiency; for this reason, we propose an induction mechanism for a welding clamp. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an induction mechanism for a welding fixture. By developing the induction mechanism, it is possible to effectively perform induction detection on automobile parts after welding, thereby avoiding the problem of welding leaks and resulting in reduced production efficiency.

[0004] The technical solution of the utility model is:

[0005] An induction mechanism for a welding fixture comprises a driving device, a first induction device, a second induction device and a welding ring; the driving device is fixedly connected to the welding ring through a connecting block, the first induction device and the second induction device are respectively installed on the outer side of the driving device, the first induction device and the second induction device are arranged at front and rear positions on the driving device, the welding ring is provided with an insertion hole and a positioning welding hole, the insertion hole and the positioning welding hole are connected, the moving end of the driving device is connected to an insertion rod, and the driving device drives the insertion rod to insert into the insertion hole and enter into the positioning welding hole.

[0006] Furthermore, the driving device adopts a driving cylinder, the push rod end of the driving device is fixedly connected to the extension rod, and the first sensing device and the second sensing device both adopt proximity switches; the first sensing device is used to sense the reset state of the push rod on the driving cylinder, and the second sensing device is used to sense the push rod push state on the driving cylinder.

[0007] Furthermore, the first sensing device is located at the left end of the second sensing device, and the first sensing device and the second sensing device are both fixed to the outside of the driving device through a fastening ring.

[0008] Furthermore, the insertion rod is a cylindrical structure, the insertion hole is a circular structure, and the outer diameter of the insertion rod is adapted to the inner diameter of the insertion hole, so that the insertion rod can slide in the insertion hole.

[0009] Furthermore, the insertion hole is arranged on the side of the welding ring, and the positioning welding hole is arranged in the inner middle part of the welding ring and is hollow from top to bottom.

[0010] Furthermore, the welding ring is an open ring structure and is fixed by bolts.

[0011] Furthermore, a fixing plate is fixedly connected to one side of the welding ring, a connecting plate is fixedly connected to one side of the fixing plate, and a fastening column is fixedly installed on the bottom surface of the connecting plate.

[0012] Furthermore, the connection plate is provided with a positioning connection hole, and the interior of the fastening column is provided with a positioning hole.

[0013] The beneficial effects of the utility model are:

[0014] Compared with the prior art, the utility model has a first sensing device and a second sensing device fixedly installed on the driving cylinder. The first sensing device can sense the reset state of the push rod on the driving cylinder, and the second sensing device can sense the push-out state of the push rod on the driving cylinder. After the driving cylinder pushes the rod out, the insertion rod connected to the push rod end can enter the positioning welding hole and touch the screw. At this time, the second sensing device lights up and transmits a signal to the controller, which controls the driving cylinder to reset the push rod and finally takes out the welded auto parts. The sensing mechanism provided in the utility model can perform sensing detection on the welded auto parts to avoid the occurrence of leaking welds and affect the production efficiency, and change the shortcomings of manual visual observation, thereby greatly improving production quality and reducing labor costs.

DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0020] like Figure 1-3 As shown,

[0021] A sensing mechanism for a welding fixture, comprising a driving device 1, a first sensing device 2, a second sensing device 3 and a welding ring 4; the driving device 1 is fixedly connected to the welding ring 4 through a connecting block 13, the first sensing device 2 and the second sensing device 3 are respectively installed on the outer side of the driving device 1, the first sensing device 2 and the second sensing device 3 are arranged at the front and rear positions on the driving device 1, the welding ring 4 is provided with an insertion hole 5 and a positioning welding hole 6, the insertion hole 5 and the positioning welding hole 6 are connected, the moving end of the driving device 1 is connected to the insertion rod 7, the driving device 1 drives the insertion rod 7 to move the driving device 1 ... The rod 7 is inserted into the insertion hole 5 and enters into the interior of the positioning welding hole 6; in the present embodiment, the stroke of the push rod at the driving end of the driving device 1 is mainly sensed by the second sensing device 3. When there is a screw inside the welding ring 4, the insertion rod 7 can touch the screw, indicating that there is no welding leak. If a welding leak occurs, the insertion rod 7 will continue to advance a certain distance. At this time, the second sensing device 3 will not light up and will also transmit a signal to the controller, starting the honeycomb to inform the staff of the welding leak. By setting the sensing mechanism, the welding leak can be effectively avoided to affect the production efficiency.

[0022] As a preferred embodiment; the driving device 1 adopts a driving cylinder, the push rod end of the driving device 1 is fixedly connected to the extension rod 7, and the first sensing device 2 and the second sensing device 3 both adopt proximity switches; the first sensing device 2 is used to sense the reset state of the push rod on the driving cylinder, and the second sensing device 3 is used to sense the push rod push-out state of the driving cylinder; it can be understood that when the push rod is reset, the first sensing device 2 will light up, and when the push rod is pushed out and the extension rod 7 touches the screw, the second sensing device 3 will light up, so that the sensing effect of the sensing mechanism is better and the probability of false sensing is lower.

[0023] As a preferred embodiment; the first sensing device 2 is located at the left end of the second sensing device 3, and the first sensing device 2 and the second sensing device 3 are both fixedly connected to the outside of the driving device 1 through a fastening ring 8; it can be understood that the first sensing device 2 and the second sensing device 3 mainly sense the stroke position of the push rod, and when the push rod is located at different positions, its working state is different, therefore, it is necessary to set the first sensing device 2 and the second sensing device 3 at different positions to ensure the sensing effect and accuracy.

[0024] As a preferred embodiment; the insertion rod 7 is a cylindrical structure, the insertion hole 5 is a circular structure, the outer diameter of the insertion rod 7 is adapted to the inner diameter of the insertion hole 5, so that the insertion rod 7 can slide in the insertion hole 5; the insertion rod 7 and the insertion hole 5 are adapted to each other, which has a positioning effect, ensuring the forward position of the insertion rod 7, and avoiding the situation where the insertion rod 7 is offset and does not touch the screw and causes misunderstanding; in addition, the adaptation setting means that the insertion rod 7 can just move inside the insertion hole 5.

[0025] As a preferred embodiment; the insertion hole 5 is arranged on the side of the welding ring 4, and the positioning welding hole 6 is arranged in the inner middle part of the welding ring 4, and is hollow in the upper and lower parts; the purpose of this structural design is: not only to make the structure more compact and save the space occupied by the sensing mechanism, but also to quickly detect the automobile welding workpiece (the insertion rod 7 is arranged close to the insertion hole 5, the insertion hole 5 is connected with the positioning welding hole 6, and the insertion rod 7 can quickly enter the interior of the positioning welding hole 6 without changing the working state of other components), which is conducive to improving production efficiency.

[0026] As a preferred embodiment; the welding ring 4 is an open ring structure and is fixed by bolts; it can be understood that the welding ring 4 with an open ring structure can fine-tune the inner diameter of the positioning welding hole 6 to make it better fit the welding head, and it is also convenient to connect the connecting block 13.

[0027] As a preferred embodiment; a fixing plate 9 is fixedly connected to one side of the welding ring 4, a connecting plate 10 is fixedly connected to one side of the fixing plate 9, and a fastening column 11 is fixedly installed on the bottom surface of the connecting plate 10; by providing the fastening column 11, the fastening column 11 mainly fixes the automobile accessory plate, which is convenient for welding screws inside the positioning welding hole 6.

[0028] As a preferred embodiment, the connecting plate 10 is also provided with a positioning connection hole 12, and the interior of the fastening column 11 is provided with a positioning hole; by providing the positioning hole and the positioning connection hole 12, a positioning pin can be inserted, which has a positioning and fixing effect.

[0029] The working principle of the utility model is as follows: the fixing plate 9 will be connected to the external lifting mechanism, and a loading platform is arranged below the sensing mechanism. When working, the automobile accessory plate is first installed on the loading platform (wherein the positioning pin on the loading platform will be plugged into the automobile accessory plate), and then the mechanism is lowered through the lifting mechanism. After it is in place, the fastening column 11 will also be plugged into the positioning pin, which has a positioning effect and can also effectively press the automobile accessory plate. Since the welding ring 4 is located on one side of the fastening column 11 and the bottom of the welding ring 4 is also the automobile accessory plate, at this time, the worker holds the welding head (the welding head is already equipped with screws) and inserts it into the positioning welding hole 6 to weld the screws to the automobile accessory plate; after the welding process is completed, the driving device 1 will work to push the insertion rod 7 along the insertion hole 5 and enter the positioning welding hole. If the screw is touched in the connection hole 6, the second sensing device 3 will light up and transmit the information to the controller. At this time, the controller will control the action of the driving device 1 and the external lifting mechanism. The driving device 1 controls the insertion rod 7 to reset and the lifting mechanism drives the mechanism to reset, and finally the welded automobile accessory plate is taken out; on the contrary, when a welding leak occurs, the insertion rod 7 will continue to advance for a distance. Since the second sensing device 3 mainly senses the stroke position of the push rod, when the distance the push rod is pushed out is not the sensing distance, the second sensing device 3 will not light up and will also transmit the information to the control. The controller will control the buzzer to start and inform the staff of the welding leak. At the same time, the controller will not control the reset action of the lifting mechanism and the driving device 1, and wait for the staff to handle it first;

[0030] It is worth mentioning that the stroke of the push rod set on the driving device 1 is the stroke when it does not touch the screw, while the stroke of the push rod sensed by the second sensing device 3 is the stroke when it touches the screw (the stroke refers to sensing the welding screw). When the screw is welded, the extension rod 7 will be blocked by the screw when it touches the screw, so that the stroke of the push rod will become the stroke of the push rod sensed by the second sensing device 3.

[0031] It should be pointed out that the main problem in the prior art is that the fixture in the prior art does not have an induction detection function after welding. When a leak occurs, it can only be observed by the naked eye. When the observation is not in place, a lot of time will be wasted, thereby greatly reducing production efficiency.

[0032] Therefore, after the improvement of this application, the sensing mechanism provided in the utility model can perform sensing detection on the welded automobile parts, avoid the occurrence of welding leaks and affect the production efficiency, and change the shortcomings of manual visual observation, thereby greatly improving the production quality and reducing labor costs.

[0033] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
