Description

Technical Field

[0001] This utility model relates to the field of expansion bolt processing technology, and in particular to an expansion bolt assembly machine. Background Technology

[0002] An internal expansion bolt consists of an extruded inner core and an expansion outer sleeve fitted on the outside of the extruded inner core. An expansion bolt assembly machine can automatically assemble the extruded inner core and the expansion outer sleeve into an expansion bolt. Most existing expansion bolt assembly machines are rotary type. The rotary type expansion bolt assembly machine includes a drive motor and a turntable connected to the drive motor through a transmission mechanism. Multiple clamping mechanisms are evenly arranged on the turntable to clamp the workpiece. Each clamping mechanism also needs to be equipped with a drive component to drive the clamping mechanism to open or close. Therefore, the rotary type expansion bolt assembly machine requires more drive mechanisms, the overall structure is more complex, and the cost is higher.

[0003] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0004] Therefore, it is necessary to provide an expansion bolt assembly machine to solve the technical problems existing in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An expansion bolt assembly machine includes: a frame, on which at least one feeding mechanism, a feeding mechanism capable of moving in a front-back direction and a left-right direction, an auxiliary clamping mechanism capable of moving in a front-back direction, a mounting base, and at least two assembly mechanisms arranged sequentially in a left-right direction are mounted. The feeding mechanism and the auxiliary clamping mechanism are both located in front of the mounting base. The feeding mechanism is slidably disposed above the auxiliary clamping mechanism. Each assembly mechanism is located above the feeding mechanism. The auxiliary clamping mechanism includes a plurality of clamping plates spaced apart, the number of clamping plates being the same as the number of assembly mechanisms and corresponding to the positions of the assembly mechanisms. Each clamping plate has a plurality of clamping slots. The feeding mechanism includes a plurality of placement plates spaced apart, the number of placement plates being at least one more than the number of clamping plates, and the spacing between adjacent placement plates being equal to the spacing between adjacent clamping plates. Each placement plate has a number of placement slots equal to the number of clamping slots and capable of aligning with the clamping slots. The placement slots and clamping slots are respectively capable of cooperating with the mounting base to clamp the workpiece to be assembled.

[0007] In one embodiment, a discharge mechanism is provided at the end of the mounting base away from the feeding mechanism. The discharge mechanism includes an inclined discharge plate. The inlet end of the inclined discharge plate is connected to the mounting base and located on the lower side of the placement plate. A discharge driver is provided on the side of the inlet end of the inclined discharge plate away from the placement plate. The output end of the discharge driver is connected to push rods corresponding to the number and position of the placement slots. Each push rod is located on the upper side of the inclined discharge plate. The discharge driver can drive each push rod to move to the lower part of the placement slot and push the workpiece in the placement slot.

[0008] In one embodiment, the mounting base is provided with a support plate, which is located below the auxiliary clamping mechanism.

[0009] In one embodiment, the feeding mechanism includes: a first lateral drive, a first longitudinal drive, and a slide plate, with each of the placement plates disposed on the slide plate. The first lateral drive is used to drive the slide plate to move in the left-right direction, and the first longitudinal drive is used to drive the slide plate to move in the front-back direction.

[0010] In one embodiment, the slide plate has a groove, and a slider that slides in the groove is provided therein, and the first longitudinal drive is connected to the slider.

[0011] In one embodiment, the auxiliary clamping mechanism further includes a second longitudinal drive and a slide block, each of the clamping plates is disposed on the slide block, the slide block is slidably disposed on the frame, the slide plate is slidably disposed on the slide block, the second longitudinal drive is drivenly connected to the slide block, and the second longitudinal drive is used to drive the slide block to move in the front-back direction.

[0012] In one embodiment, the mounting base is provided with a feeding plate, and the feeding plate has a number of feeding slots equal to the number of placement slots on the placement plate. The mounting base is also provided with a feeding driver and sealing members corresponding to the number and position of the feeding slots. The feeding driver can drive each of the sealing members to be inserted into the corresponding feeding slot.

[0013] In one embodiment, the feeding mechanism includes a vibrating feeding plate and a discharge pipe, wherein the number of discharge pipes is equal to the number of feeding troughs, one end of the discharge pipe is connected to the vibrating feeding plate, and the other end of the discharge pipe is aligned with the feeding hole.

[0014] The beneficial effects of this utility model are as follows: By providing an expansion bolt assembly machine, the feeding mechanism first moves forward to abut against the mounting base, and then the loading mechanism can feed the workpieces, which are equal in number to the number of slots on a mounting plate, into each slot. Then, the feeding mechanism drives each workpiece to move to the right, which can transport each workpiece to the first assembly mechanism. After the processing component is completed, the feeding mechanism moves backward while the auxiliary clamping mechanism moves forward to abut against the mounting base to clamp each workpiece, preventing the workpiece from falling off when the feeding mechanism moves backward. Finally, after the feeding mechanism moves to the left and returns to the initial position, the feeding mechanism moves forward again to cooperate with the loading mechanism to feed the second batch of workpieces into each slot. Then, the auxiliary clamping mechanism moves backward to release the clamp on the first batch of workpieces. The above steps are repeated to realize that subsequent batches of workpieces can be sent to each assembly mechanism for assembly. With the above settings, only three drive mechanisms are needed to sequentially transport the expansion bolts to each assembly mechanism to complete multiple assembly processes, which greatly reduces the number of drive mechanisms and reduces the cost of the equipment.

Detailed Implementation

[0024] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the device includes: a frame 1010, on which at least one feeding mechanism 2020, a feeding mechanism 3030 capable of moving in the front-back and left-right directions, an auxiliary clamping mechanism 4040 capable of moving in the front-back direction, a mounting base 5050, and at least two assembly mechanisms 7070 arranged sequentially in the left-right direction are provided. The feeding mechanism 3030 and the auxiliary clamping mechanism 4040 are both located in front of the mounting base 5050. The feeding mechanism 3030 is slidably disposed above the auxiliary clamping mechanism 4040. Each assembly mechanism 7070 is located above the feeding mechanism 3030. The auxiliary clamping mechanism 4040 includes a plurality of clamping plates 421 spaced apart, the number of clamping plates 421 being greater than the number of clamping plates 421. The number of assembly mechanisms 7070 is at least one more and is arranged in a position corresponding to the assembly mechanism 7070. Each clamping plate 421 has a plurality of clamping slots 422422. The feeding mechanism 3030 includes a plurality of placement plates 3434 arranged at intervals. The number of placement plates 3434 is the same as the number of clamping plates 421, and the distance between adjacent placement plates 3434 is equal to the distance between adjacent clamping plates 421. Each placement plate 3434 has a number of placement slots 341 equal to the number of clamping slots 422422 and can be aligned with the clamping slots 422422. The placement slots 341 and the clamping slots 422422 can each cooperate with the mounting base 5050 to clamp the workpiece to be assembled.

[0025] Specifically, the leftmost placement plate 34 of the feeding mechanism 30 is defined as the first placement plate 34. When the first placement plate 34 of the feeding mechanism 30 abuts against the side of the mounting base 50, the loading mechanism 20 feeds the first batch of workpieces into the placement groove 341 of the first placement plate 34. Then, the feeding mechanism 30 moves to the right to transport the first batch of workpieces to the first assembly mechanism 70. To improve production efficiency, the second batch of workpieces is fed simultaneously while the first assembly mechanism 70 is processing the first batch of workpieces. At this time, the auxiliary clamping mechanism 40 moves forward and abuts against the side of the mounting base 50 to clamp the first batch of workpieces in the clamping groove 422. This allows the first batch of workpieces to be held in the position of the first assembly mechanism 70 for processing, and also allows the first batch of workpieces to be separated from the feeding mechanism 30. At the same time, the feeding mechanism 30 first moves backward to separate from the first batch of workpieces, and then moves to the left to return to the initial position. After the feeding mechanism 30 returns to the initial position, the feeding mechanism 30 moves forward... When the moving part abuts against the side of the mounting base 50, the feeding mechanism 20 feeds the second batch of workpieces into the placement slot 341 of the first placement plate 34. The placement slot 341 of the second placement plate 34, located to the right of the first placement plate 34, clamps the first batch of workpieces. In order for the feeding mechanism 30 to feed to the right normally, during the forward movement of the feeding mechanism 30, the auxiliary clamping mechanism 40 moves backward to release the clamping of the first batch of workpieces, thereby enabling the feeding mechanism 30 to feed to the right normally. Then, the feeding mechanism 30 moves to the right to send the first batch of workpieces to the second assembly mechanism 70, and the second batch of workpieces to the first assembly mechanism 70. By repeating the above steps, the feeding mechanism 30 can send each batch of expansion bolt shells to each assembly mechanism 70 for processing. Since the feeding mechanism 30 only needs to move forward and backward and left and right, and the auxiliary clamping mechanism 40 only needs to move forward and backward, only three drive mechanisms are needed to sequentially send the expansion bolts to each assembly mechanism 70 to complete multiple assembly processes, which greatly reduces the number of drive mechanisms and reduces the cost of the equipment. It should be noted that since the feeding mechanism 20 only feeds materials and does not require material replacement, there is no clamping plate 421 at the position corresponding to the feeding mechanism 20.

[0026] In this embodiment, the expansion bolt assembly machine is used to assemble internal expansion bolts. There are five assembly mechanisms 70, five clamping plates 421, and six placement plates 34. The five assembly mechanisms 70 specifically include: a first detection mechanism, a second detection mechanism, an extrusion core unloading mechanism, a pressing mechanism, and a thread drilling mechanism. The first detection mechanism, extrusion core unloading mechanism, second detection mechanism, pressing mechanism, and thread drilling mechanism are sequentially arranged on the frame 10 from left to right. The feeding mechanism 20 is used to store and transport the expansion bolt shells. The extrusion core unloading mechanism is used to transport the extrusion core into the expansion bolt shell. The first detection mechanism, extrusion core unloading mechanism, second detection mechanism, pressing mechanism, and thread drilling mechanism are located on the top surface of the mounting base 50. Following the above steps, each batch of expansion bolt shells is sequentially transported to the first detection mechanism, extrusion core unloading mechanism, second detection mechanism, pressing mechanism, and thread drilling mechanism. The first detection mechanism is used to detect that the expansion bolt shells are in the placement groove 341. If the height of the expansion bolt shell meets the requirements, the feeding mechanism 30 will transport the expansion bolt shell to the extrusion core unloading mechanism. The extrusion core unloading mechanism will send the extrusion core into the expansion bolt shell. Then, the second detection mechanism will detect whether the extrusion core has fallen correctly into the expansion bolt shell. If the extrusion core is present in the expansion bolt shell, it meets the assembly requirements. Then, the pressing mechanism will press down on the extrusion core in the expansion bolt shell, so that the extrusion core is clamped in the expansion bolt shell and is firmly connected to form a whole. Finally, the thread drilling mechanism will process the internal thread on the inner surface of the expansion bolt shell. It should be noted that the first detection mechanism, the extrusion core unloading mechanism, the second detection mechanism, the pressing mechanism, and the thread drilling mechanism are common structures used by those skilled in the art. Their working principles and structures will not be described in detail. The assembly mechanism 70 is not limited to the above structure. If there are other processing mechanisms, they will also be included in the assembly mechanism 70. The number of placement plates 34 and clamping plates 421 will be dynamically adjusted according to the number of assembly mechanisms 70.

[0027] In one embodiment, such as Figure 1 and Figure 2As shown, a discharge mechanism 60 is provided at one end of the mounting base 50 away from the feeding mechanism 20. The discharge mechanism 60 includes an inclined discharge plate 63. The inlet end of the inclined discharge plate 63 is connected to the mounting base 50 and is located on the lower side of the placement plate 34. A discharge driver 61 is provided on the side of the inlet end of the inclined discharge plate 63 away from the placement plate 34. The output end of the discharge driver 61 is connected to push rods 62 corresponding to the number and position of the placement slots 341. Each push rod 62 is located on the upper side of the inclined discharge plate 63. The discharge driver 61 can drive each push rod 62 to move to the lower side of the placement slot 341 and push the workpiece in the placement slot 341. Specifically, after the expansion bolts are assembled, the feeding mechanism 30 moves to the right to transport the expansion bolts to the clamping slots 422 of the clamping plate 421 furthest from the loading mechanism 20. The clamping plate 421 and the mounting base 50 clamp the expansion bolts together. After the feeding mechanism 30 returns to its initial position, it moves forward so that the placement slots 341 on the placement plate 34 furthest from the loading mechanism 20 clamp the expansion bolts. Then, the feeding mechanism 30 moves to the right to transport the assembled expansion bolts to the top of the inlet end of the inclined discharge plate 63. The expansion bolts at this position are freed from the restriction of the mounting base 50. At this time, the discharge driver 61 drives the push rods 62 to move forward and push the expansion bolts out of the placement slots 341 and onto the inclined discharge plate 63, thereby completing the unloading process.

[0028] In one embodiment, such as Figure 5 and Figure 6 As shown, a support plate 55 is provided on the mounting base 50. The support plate 55 is located below the auxiliary clamping mechanism 40. When the end of the expansion bolt housing enters the placement groove 341, the support plate 55 can support the end of the expansion bolt housing, preventing the expansion bolt housing from continuously moving downward and coming out of the placement groove 341.

[0029] In one embodiment, such as Figure 1 and Figure 3 As shown, the feeding mechanism 30 includes: a first transverse drive 31, a first longitudinal drive 32, and a slide plate 33. The first transverse drive 31 and the first longitudinal drive 32 are both fixedly connected to the frame 10. Each of the placement plates 34 is disposed on the slide plate 33. The first transverse drive 31 and the first longitudinal drive 32 are both electric push rods 62. The first transverse drive 31 is used to drive the slide plate 33 to move in the left and right direction, and the first longitudinal drive 32 is used to drive the slide plate 33 to move in the front and back direction.

[0030] In one embodiment, such as Figure 3As shown, the slide plate 33 has a groove 331, and a slider 332 that slides and engages with the groove 331 is provided in the groove 331. The first longitudinal drive 32 is connected to the slider 332. Specifically, since the slider 332 is driven and connected to the first longitudinal drive 32, the slider 332 and the transverse movement device are a whole, so that the slider 332 is relatively fixed on the frame 10. When the first transverse drive 31 drives the slide plate 33 to move in the left and right direction, the slide plate 33 slides while the slider 332 remains stationary, so that the slider 332 and the slide plate 33 slide relative to each other, avoiding movement obstruction between the slide plate 33 and the first longitudinal drive 32 when the slide plate 33 slides.

[0031] In one embodiment, such as Figure 1 and Figure 6 As shown, the auxiliary clamping mechanism 40 further includes a second longitudinal drive 41 and a slide 42. Each clamping plate 421 is disposed on the slide 42, the slide 42 is slidably disposed on the frame 10, the slide plate 33 is slidably disposed on the slide 42, the second longitudinal drive is drivenly connected to the slide 42, wherein the second longitudinal drive 41 is fixedly connected to the frame 10, and the second drive is an electric push rod 62. The second longitudinal drive 41 can drive the slide 42 to move in the front-back direction.

[0032] In one embodiment, such as Figure 7 As shown, the mounting base 50 is provided with a feeding plate 51, and the feeding plate 51 has a number of feeding slots equal to the number of placement slots 341 of the placement plate 34. The mounting base 50 is also provided with a feeding driver 53 and sealing members 54 corresponding to the number and position of the feeding slots. The feeding driver 53 can drive each of the sealing members 54 to be inserted into the corresponding feeding slot. Specifically, when the placement plate 34 is not in contact with the side of the mounting base 50, the sealing members 54 block the feeding hole 52. At this time, the expansion bolt housings conveyed by the feeding mechanism 20 to the placement slot 341 are blocked in the feeding hole 52. When the placement plate 34 is in contact with the side of the mounting base 50, the feeding hole 52 is connected to the placement slot 341, and the feeding driver 53 drives each sealing member 54 away from the feeding hole 52. Then the expansion bolt housings enter the placement slot 341 through the feeding hole 52 to ensure the normal operation of the feeding mechanism 20.

[0033] In one embodiment, such as Figure 7As shown, the feeding mechanism 20 includes a vibrating feeding plate 21 and a discharge pipe 22. The number of discharge pipes 22 is equal to the number of feed troughs. One end of each discharge pipe 22 is connected to the vibrating feeding plate 21, and the other end of each discharge pipe 22 is aligned with the feed hole 52. Specifically, the vibrating feeding plate 21 can be used to convey the expansion bolt shell into the discharge pipe 22. The expansion bolt shell and the bolt are then conveyed along the discharge pipe 22 to the feed hole 52. It should be noted that the vibrating feeding plate 21 is a commonly used component by those skilled in the art; therefore, its feeding principle and structure will not be described in detail.
