Description

TECHNICAL FIELD

[0001] The utility model relates to motor cap repair technology field, concretely relates to a cap mounting clamp. BACKGROUND

[0002] The electrode cap belongs to one kind of welding electrode, and is used for the welding of resistance welding equipment, such as fixed spot welder, suspended spot welder and mechanical hand spot welder etc., because it is sleeved on the electrode connecting rod, it is called electrode cap. The electrode cap needs to be polished during production. In addition, the electrode cap needs to be regularly repaired or replaced after being used for a period of time, that is, after a certain number of weldings, to ensure the welding effect, and the electrode cap belongs to welding consumables. Modern automobile production lines generally use robots for resistance welding, and the electrode cap used for welding is frequently turned on and off and subjected to pressure during robot welding, so the electrode cap wears out quickly, and an oxidation layer is easily formed on the surface of the electrode cap, which damages the electrode cap. The damaged electrode cap will seriously affect the welding quality. In order to eliminate the adverse effects of electrode cap wear and electrode oxidation layer on welding, the common practice is to repair the electrode cap after a certain number of uses, and when the outer wall thickness of the repaired electrode cap is less than the specified allowable thickness, a new electrode cap needs to be replaced.

[0003] No matter during production or in the process of use, the electrode cap is usually polished by an electrode cap polisher, and the cap mounting clamp is essential during polishing. The electrode cap mounting clamp of the existing servo automatic cap changing and polishing device adopts a spring compression feeding mode, which cannot stably feed the electrode caps one by one. The electrode cap at the front is prone to displacement and falling out due to insufficient pressing, and the stability is poor. SUMMARY

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a cap mounting clamp, which can stably deliver electrode caps, prevent electrode caps from displacing, and improve the stability of delivery.

[0005] To solve the above-mentioned technical problems, the utility model includes a storage body, which is characterized in that a cap storage groove is formed on the storage body, a cover plate covers the cap storage groove, the cap storage groove extends along the length direction of the storage body and penetrates the storage body, a plurality of electrode caps and a pushing mechanism for pushing the electrode caps to move are arranged in the cap storage groove, and a positioning mechanism for positioning the cap storage groove to be grabbed is further arranged in the cap storage groove. The end of the storage body away from the pushing mechanism is further provided with a cap pressing mechanism and a limiting mechanism respectively located on both sides of the corresponding cap storage groove.

[0006] After the structure is used, firstly, the multiple electrode caps are placed in the cap storage groove, at this time, the pushing mechanism in the cap storage groove is in the contraction state and pushes against the electrode cap adjacent to the end portion thereof, the limiting mechanism abuts against the electrode cap at the foremost end, the electrode cap is limited in the length direction of the cap storage groove, and the cap pressing mechanism presses the top surface of the electrode cap at the foremost end; when the cap is taken, the electrode cap at the foremost end is taken away, and under the pushing of the pushing mechanism, the electrode cap next thereto moves to the positioning mechanism, the cap pressing mechanism presses the top surface of the electrode cap, the limiting mechanism limits the electrode cap from continuing to move forward, and prevents the electrode cap from falling out. The utility model can stably deliver the electrode cap, prevent the electrode cap from being displaced, and improve the stability of delivery.

[0007] Preferably, the pushing mechanism comprises a conveying spring installed in the cap storage groove, a guide shaft is sleeved in the conveying spring, and the end portion of the guide shaft pushes against the electrode cap adjacent thereto.

[0008] Preferably, the bottom surface of the cap storage groove away from the conveying spring is further provided with a block mounting groove and a recess arranged at intervals, a push block is slidably connected in the block mounting groove, and the push block is adapted to the cap storage groove and pushes against the electrode cap adjacent thereto.

[0009] Preferably, the positioning mechanism comprises a positioning seat installed on the recess, the top surface of the positioning seat is provided with a recessed slide, and the slide is adapted to the electrode cap.

[0010] Preferably, the end portion of the storage body away from the pushing mechanism is provided with a cap pressing groove, the cap pressing mechanism comprises a spring cap rotationally connected in the cap pressing groove and a pressing spring abutting against one end of the spring cap, and the other end of the spring cap is pressed on the electrode cap.

[0012] This invention allows for the storage of more electrode caps by placing them in the cap slots of the storage body. A pushing mechanism, when the foremost electrode cap is picked up, pushes a block under the action of a conveying spring, moving the electrode cap adjacent to its reel along the block mounting groove. This ensures the electrode cap enters the slideway stably, guaranteeing stable delivery. A positioning mechanism within the cap slot positions the electrode caps within the slideway. A pressing mechanism, with a spring cap pressing against the electrode cap after it enters the slideway, prevents vertical movement. A limiting mechanism, with a limiting block under the action of a torsion spring, presses against the electrode cap to prevent displacement. This invention provides stable delivery of electrode caps, preventing displacement and improving overall delivery stability. Attached Figure Description

[0034] ​​​​​​​​Currently, electrode caps require grinding during production. Additionally, after a period of use, i.e., after a certain number of welding operations, electrode caps also need periodic grinding or replacement due to wear to ensure welding quality. Electrode caps are considered welding consumables. Whether during production or use, electrode cap grinders are typically used for grinding. During grinding, cap clamping is essential. Existing servo-controlled automatic cap changers and grinders use a spring-compression feeding method for the cap clamps, which cannot reliably feed electrode caps one by one. The cap at the front is prone to displacement due to insufficient pressure and is easily dropped, resulting in inaccurate positioning and poor stability when gripping electrode caps. To address the aforementioned issues, a cap holder is provided, comprising a storage body with a cap storage slot covered by a cover plate. The cap storage slot extends along the length of the storage body and penetrates it. A plurality of electrode caps and a pushing mechanism for moving the electrode caps are disposed within the cap storage slot. A positioning mechanism for positioning the caps to be grasped is also provided within the cap storage slot. A cap pressing mechanism and a limiting mechanism are respectively located on both sides of the corresponding cap storage slot at the end of the storage body away from the pushing mechanism. With the above structure, multiple electrode caps are placed in the cap storage slot. At this time, the pushing mechanism in the storage slot is in a retracted state and presses against the electrode cap adjacent to its end. The limiting mechanism presses against the foremost motor cap, limiting the electrode cap along the length of the storage slot. The cap pressing mechanism presses against the top surface of the foremost electrode cap. When the cap is removed, after the foremost electrode cap is taken away, the electrode cap immediately adjacent to it moves forward to the positioning mechanism under the push of the pushing mechanism. The cap pressing mechanism presses against the top surface of this electrode cap, and the limiting mechanism restricts the electrode cap from moving further forward, preventing it from falling out. This structure can stably deliver electrode caps one by one. The foremost electrode cap will not fall out due to insufficient pressing, exhibiting high stability. This invention can stably deliver electrode caps, prevent electrode cap displacement, and improve the stability of the delivery process.
