Description

Technical Field

[0001] The present application relates to the field of contact production, and in particular to a contact riveting machine. Background Art

[0002] Contacts are often needed in relays. They are used at the ends of the on-off connection parts so that the on-off parts can better realize current conduction. The production of some contacts requires riveting steps. Currently, workers usually use tweezers to clamp the contacts to the riveting equipment for riveting, which is inefficient. Utility Model Content

[0003] In order to improve the problem of low riveting efficiency when workers clamp contacts onto riveting equipment, the present application provides a contact riveting machine.

[0004] The present application provides a contact riveting machine, which adopts the following technical solution:

[0005] A contact riveting machine includes a positioning mechanism, a pushing mechanism and a loading mechanism. The loading mechanism is used to load contacts onto the pushing mechanism, the pushing mechanism is used to separate the contacts one by one and push them into the positioning mechanism, and the positioning mechanism is used to position the contacts for riveting.

[0006] By adopting the above technical solution, the contacts can be automatically loaded and then riveted, which greatly improves the efficiency of contact riveting. It does not require workers to use tweezers to clamp the contacts for loading, thereby improving the degree of automation. Workers who use tweezers to stare at small contacts for a long time will easily become tired, affecting efficiency and also affecting eyesight. It plays a protective role for workers and improves the efficiency of contact processing.

[0007] Optionally, the positioning mechanism includes a positioning seat, and the positioning seat is provided with a positioning groove for the contact to slide into and position.

[0008] By adopting the above technical solution, the contacts are positioned and riveted through the positioning grooves, thereby improving the stability of the contacts.

[0009] Optionally, the positioning mechanism further includes a mounting seat, and the positioning seat is detachably mounted on the mounting seat.

[0010] By adopting the above technical solution, the positioning seat can be detachably mounted on the mounting seat, so that different types of contacts can be adapted by simply replacing the positioning seat, thereby expanding the adaptation range and enabling more convenient adaptation.

[0011] Optionally, the mounting seat is provided with a mounting groove for the positioning seat to be inserted and installed.

[0012] By adopting the above technical solution, the positioning seat is limited by the installation slot, and the positioning seat only needs to be inserted into the installation slot to complete the installation. When replacing, it is only necessary to pull the positioning seat out of the installation slot and reinsert it into another positioning seat. It is convenient and fast, and can quickly adapt to different types of contact riveting.

[0013] Optionally, a positioning half ring is provided on the mounting seat, the mounting groove is formed between the positioning half ring and the side wall of the mounting seat, and an observation window for observing whether the positioning seat is installed in place is formed between the positioning half ring and the bottom wall of the mounting seat.

[0014] By adopting the above technical solution, it is possible to observe through the observation window whether the positioning seat is installed in place. At the same time, the contact area between the worker and the outer wall of the positioning seat is increased through the positioning half ring, so that the worker can remove the positioning seat from the installation groove, making it easier to remove the positioning seat.

[0015] Optionally, a fixing hole is formed on the mounting seat, the fixing hole is communicated with the mounting groove, and a thread is formed on the inner wall of the fixing hole.

[0016] By adopting the above technical solution, components such as bolts can be inserted into the installation groove through the fixing holes, so that the positioning seat is pressed against the inner wall of the installation groove, thereby improving stability.

[0017] Optionally, the pushing mechanism includes a pushing track and a pushing assembly. The loading mechanism loads the contact onto the pushing track. The width of the pushing track is only enough for one contact to slide inside. The pushing assembly pushes the contact in the pushing track into the positioning groove along the pushing track.

[0018] By adopting the above technical solution, the contacts are separated one by one through the pushing track and the pushing assembly and then pushed into the positioning groove, thereby improving efficiency.

[0019] Optionally, the pushing track is perpendicular to the feeding direction of the feeding mechanism.

[0020] By adopting the above technical solution, the probability of the rear contacts pushing the front contacts directly into the pushing track in large quantities, thereby affecting the operation of the pushing assembly, is reduced, and stability is improved.

[0021] Optionally, the pushing assembly includes a pushing block and a pushing driving member for driving the pushing block to slide, the pushing block is provided with a card slot, the loading mechanism loads the contacts into the card slot, and the end of the pushing block away from the pushing driving member is provided with a clearance slot connected to the card slot, and the clearance slot is for the contacts that fall into the positioning slot to make way.

[0022] By adopting the above technical solution, the contacts are clamped by the clamping groove, thereby further improving the stability of contact loading.

[0023] Optionally, the feeding mechanism includes a vibration plate and a guide rail, the vibration plate is used to store the contacts and output the feeding, the guide rail is connected between the discharge end of the vibration plate and the feed end of the pushing mechanism, and the width of the guide rail is only enough for one contact to pass through.

[0024] By adopting the above technical solution, a large number of contacts are stored on the vibration plate and then loaded in sequence, which is convenient and fast.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Improve the degree of automation, greatly improve the efficiency of contact riveting, and play a protective role for workers.

[0027] 2. It can adapt to different types of contacts, expand the adaptation range, and can also adapt more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a contact riveting machine. Figure 1 and Figure 2The contact riveting machine includes a positioning mechanism 1, a pushing mechanism 2, and a loading mechanism 3. The loading mechanism 3 stores contacts and loads them onto the pushing mechanism 2. The pushing mechanism 2 is used to separate the large number of loaded contacts one by one and then push a contact into the positioning mechanism 1. The positioning mechanism 1 is used to position the contact for riveting. In this embodiment, the direction of gravity is downward, and the direction opposite to downward is upward.

[0034] Reference Figure 2 The positioning mechanism 1 includes a positioning seat 11 and a mounting seat 13. The mounting seat 13 is provided with a mounting groove 14. The mounting groove 14 extends downward from the edge of the upper end surface of the mounting seat 13, but the mounting groove 14 does not penetrate downward through the mounting seat 13. The bottom end of the mounting groove 14 is the bottom wall, and the side edges extending therefrom are the side walls. A positioning semi-ring 15 is fixedly connected to the side wall of the mounting groove 14. The positioning semi-ring 15 is semi-annular in shape. The mounting groove 14 extends between the positioning semi-ring 15 and the side wall of the mounting groove 14. In this application, the cross-section of the mounting groove 14 is circular. The positioning semi-ring 15 is located at half the length of the extending mounting groove 14, that is, both the upper and lower ends of the positioning semi-ring 15 have through grooves connected to the mounting groove 14, and the through groove at the lower end of the positioning semi-ring 15 is an observation window 151. The observation window 151 is connected to the mounting groove 14 for workers to observe.

[0035] Reference Figure 2 The positioning seat 11 is inserted into the mounting groove 14, and the outer side wall of the positioning seat 11 is simultaneously fitted with the side wall of the mounting groove 14 and the inner side wall of the positioning half ring 15. The positioning seat 11 is inserted into the mounting groove 14 from top to bottom, and the lower end of the positioning seat 11 is in contact with the bottom wall of the mounting groove 14. The positioning half ring 15 is clamped and limited, and the upper end face of the positioning seat 11 is flush with the upper end face of the mounting seat 13. A positioning groove 12 is provided on the upper end face of the positioning seat 11. The pushing mechanism 2 pushes the contact into the positioning groove 12, and the inner wall of the positioning groove 12 clamps and limits the contact. A plurality of fixing holes 16 are formed through the side wall of the mounting seat 13. The fixing holes 16 extend from the outer wall of the mounting seat 13 into the mounting groove 14. The extending direction of the fixing holes 16 is not tangent to the outer wall of the mounting groove 14, that is, the extending direction of the fixing holes 16 points into the mounting groove 14. The inner wall of the fixing hole 16 is formed with a thread for a bolt to be screwed into the threaded connection to tighten against the positioning seat 11.

[0036] Reference Figure 1 and Figure 2 The feeding mechanism 3 includes a vibration disk 31 and a guide rail 32. The vibration disk 31 is used to store and output the contacts. The guide rail 32 is connected between the discharge end of the vibration disk 31 and the feed end of the pushing mechanism 2. The width of the guide rail 32 is only enough for one contact to pass through. The contacts output by the vibration disk 31 are stacked one by one in the guide rail 32.

[0037] Reference Figure 2 and Figure 3The pushing mechanism 2 includes a pushing track 21 and a pushing assembly 22. The width of the pushing track 21 is also only enough for one contact to pass through, that is, the cross-sectional width of the space used by the pushing track 21 and the guide rail 32 to transmit the contacts is greater than the diameter of one contact but less than twice the diameter of the contact. The extension direction of the pushing track 21 is perpendicular to the feeding direction of the guide rail 32, and the extension direction of the pushing track 21 is the transmission direction of the contacts therein.

[0038] Reference Figure 1 and Figure 3 When the pusher 221 is in the position closest to the positioning groove 12, the clamping groove 223 is connected to the positioning groove 12 so that the contact in the clamping groove 223 falls into the positioning groove 12.

[0039] Reference Figure 3 The end of the pushing block 221 away from the pushing driving member 222 is provided with a clearance groove 224 connected to the clamping groove 223. The clearance groove 224 is located at the lower end of the end of the pushing block 221. That is, when the contact falls into the positioning groove 12, the pushing block 221 needs to retreat. At this time, the end of the contact part protrudes outside the positioning groove 12. The clearance groove 224 makes way for this part of the contact, so that the pushing block 221 can retreat smoothly.

[0040] The implementation principle of a contact riveting machine in an embodiment of the present application is as follows: the vibration plate 31 vibrates the contact into the clamping groove 223 through the guide rail 32, the telescopic rod of the pushing drive 222 pushes the pushing block 221 close to the positioning groove 12, and the contact in the clamping groove 223 falls into the positioning groove 12.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
