Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to an automatic feeding mechanism for drilling pipe joints. Background Technology

[0002] During the processing of pipe fittings, machine tools are needed to treat the pipe fitting blanks, such as drilling and deburring. With technological advancements, automated processing has become the mainstream technology; however, the blanks still require loading during the processing.

[0003] Existing technologies include automated feeding and drilling equipment. A search revealed a Chinese invention patent application (publication number: CN121423672A) that discloses an automated drilling device and method for silencer pipe joints. During the feeding of the silencer pipe joint, a limiting and guiding mechanism prevents it from falling off. When the joint reaches below the first drilling mechanism, the controller stops feeding and clamps it, then starts the first drilling mechanism and two second drilling mechanisms to drill simultaneously, achieving simultaneous drilling of two joints, improving efficiency and reducing costs.

[0004] Based on the above analysis, the customized design of this automatic feeding drilling equipment significantly increases its cost. Furthermore, the complex structural design of existing equipment further drives up manufacturing costs. In addition, as an integrated system, this equipment occupies a large space, making it difficult to meet the actual needs of most small and micro-sized enterprises.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an automatic feeding mechanism for drilling pipe joints.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An automatic feeding mechanism for drilling pipe joints includes a feeding track, a transfer component, and a feeding assembly. The feeding assembly is installed on the transfer component. The feeding track has a discharge port. The transfer component transfers workpieces from the feeding track to the feeding assembly. The feeding assembly pushes the workpieces to a workpiece receiving structure. The transfer component includes a movable block that moves along a first direction between a first position and a second position. The movable block has an inlet, a outlet, and a connecting channel connecting the inlet and the outlet. When the movable block is in the second position, the outlet corresponds to the inlet. The feeding assembly includes a connecting block and a push plate. The connecting block and the push plate are movable in a second direction. The connecting block has a storage slot for receiving workpieces. In the first direction, the storage slot has a slot opening that corresponds to the position of the unloading port. In the second direction, the storage slot has an opening that corresponds to the position of the workpiece receiving structure. The push plate is slidably mounted on the storage slot in the second direction.

[0008] Furthermore, the transfer assembly also includes a first linear drive member, which drives the movable block to move along a first direction. The feeding assembly also includes a second linear drive member, which is mounted on the movable block and drives the connecting block and the push plate to move along a second direction.

[0009] Furthermore, the second linear drive component is a first cylinder, the first cylinder having a first piston rod extending in a second direction, the connecting block being mounted on the outer periphery of the first piston rod, and the push plate being mounted on the end of the first piston rod away from the first cylinder.

[0010] Furthermore, the push plate has a first surface and a second surface opposite to each other. The first surface can contact the workpiece. The connecting block is provided with a connecting cavity. The end of the connecting cavity near the first cylinder has a connecting surface. An elastic element is connected between the connecting surface and the second surface. The elastic element always has the tendency to drive the push plate to move closer to the connecting surface.

[0011] Furthermore, the second surface is provided with a fixing rod, and one end of the fixing rod away from the second surface abuts against the connecting surface.

[0012] Furthermore, the workpiece receiving structure is a machine tool chuck, which has a clamping hole, and the connecting block is provided with an insertion part extending in the second direction, which can be matched with the clamping hole.

[0013] Furthermore, the feeding track includes a fixed plate, a baffle, and an adjusting column. The baffle is installed on the fixed plate, and the adjusting column is slidably installed on the fixed plate along the second direction. A feeding trough is formed between the adjusting column, the baffle, and the fixed plate.

[0014] Furthermore, the fixing plate is provided with an oblong hole extending along the second direction, the adjusting column is provided with a fixing block, and an adjusting bolt is installed in the fixing block, the adjusting bolt being slidably installed in the oblong hole.

[0015] Furthermore, the baffle is equipped with a second cylinder, the second cylinder having a second piston rod extending in a second direction, the second piston rod being movably mounted in the feeding trough in the second direction, the second piston rod being used to block the workpiece in the feeding trough.

[0016] Furthermore, an adjustment assembly is installed on the movable block. The adjustment assembly includes a mounting block, an adjustment plate, and a fixing bolt. The adjustment plate has an adjustment groove extending along a first direction. The fixing bolt is installed on the mounting block and is relatively slidably installed in the adjustment groove. The second linear drive is fixedly installed on the adjustment plate.

[0017] With the above structure, the automatic feeding mechanism for drilling pipe joints described in this utility model has the following advantages: the automatic and orderly feeding of workpieces is achieved through the coordinated work of the feeding track, the transfer component, and the feeding component. The transfer component switches the position of the movable block through the first linear drive component to control the workpiece to fall into the placement slot. In the feeding component, the second linear drive component drives the push plate and the connecting block to push the workpiece to the machine tool chuck. The structure is simpler and can be directly installed on ordinary machine tools, thus having a wider range of applications. Attached Figure Description

[0023] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 11 As shown, an automatic feeding mechanism for drilling pipe joints includes a feeding track 4, a transfer component 2, and a feeding component 3. The feeding track 4 has a discharge port 400. The feeding track 4 is mounted on a machine tool 1, and the machine tool 1 is equipped with a fixed frame 11. The transfer component 2 is mounted on the fixed frame 11. The transfer component 2 transfers the workpiece on the feeding track 4 to the feeding component 3. The feeding component 3 pushes the workpiece to the workpiece receiving structure. The transfer component 2 includes a first linear drive 21 and a movable block 22. In this embodiment, the first linear drive 21 is a linear slide, and since linear slides are existing technology, they will not be described in detail here. The movable block 22 has a feed port 221, a discharge port 222, and a connecting channel 220 connecting the feed port 221 and the discharge port 222. The first linear drive 21 drives the movable block 22 to move along a first direction between a first position and a second position. The first direction is defined as... Figure 4 In the Z-axis direction, when the movable block 22 is in the first position, the discharge port 400 and the inlet port 221 are offset. At this time, the workpiece on the loading track 4 will not enter the connecting channel 220. When the movable block 22 is in the second position, the discharge port 400 and the inlet port 221 are set accordingly. At this time, the workpiece on the loading track 4 can enter the connecting channel 220 through the inlet port 221 and fall to the loading assembly 3 through the discharge port 222. The feeding assembly 3 includes a second linear drive 31, a connecting block 32, and a push plate 33. The second linear drive 31 is mounted on the movable block 22. The second linear drive 31 drives the connecting block 32 and the push plate 33 to move along a second direction, which is defined as... Figure 4 In the X-axis direction, the connecting block 32 has a workpiece receiving slot 320, such as... Figures 8 to 10 As shown, along the first direction, the storage groove 320 is provided with a groove 3201, which corresponds to the position of the unloading port 222. Along the second direction, the storage groove 320 is provided with an opening 3202, which corresponds to the position of the workpiece receiving structure. The push plate 33 can be slidably installed on the storage groove 320 along the second direction. The connecting block 32 moves along the second direction until it abuts against the workpiece receiving structure and then stops. The push plate 33 continues to move along the second direction to push the workpiece out of the storage groove, thereby realizing the feeding function. It should be noted that when the movable block 22 is in the second position, the opening 3202 corresponds to the position of the workpiece receiving structure.

[0025] In this embodiment, the second linear drive 31 is a first cylinder 311. The first cylinder 311 has a first piston rod 312 extending along the second direction. A connecting block 32 is installed on the outer periphery of the first piston rod 312. The connecting block 32 and the first piston rod 312 can slide relative to each other. A push plate 33 is installed at the end of the first piston rod 312 away from the first cylinder 311.

[0026] The push plate 33 has a first surface 3301 and a second surface 3302. The first surface 3301 can contact the workpiece. By contacting the workpiece with the first surface 3301 of the push plate 33, the function of pushing the workpiece to move is realized. The connecting block 32 is provided with a connecting cavity. The end of the connecting cavity near the first cylinder 311 has a connecting surface 322. An elastic element 34 is connected between the connecting surface 322 and the second surface 3302. The elastic element 34 always has the tendency to drive the push plate 33 to move towards the side closer to the connecting surface 322. In this embodiment, the elastic element 34 is a tension spring. Further optimized, the second surface 3302 is provided with a first connecting plate 331, and the connecting surface 322 is provided with a second connecting plate 323. The first connecting plate 331 and the second connecting plate 323 are respectively provided with through holes 330 for the end of the pull ring to hook into. In this embodiment, the first connecting plate 331, the second connecting plate 323 and the pull ring are all configured in two sets, thereby significantly enhancing the stability of the resetting process of the connecting block 32 and the push plate 33.

[0027] The second surface 3302 is also provided with a fixing rod 332. The end of the fixing rod 332 away from the second surface 3302 abuts against the connecting surface 322. Through the abutting cooperation between the fixing rod 332 and the connecting surface 322, the freedom of the push plate 33 along the second direction is at least restricted.

[0028] In this embodiment, the workpiece receiving structure is a machine tool chuck 12. The machine tool chuck 12 has a clamping hole 10. The connecting block 32 is provided with a plug-in portion 321 extending in the second direction. The plug-in portion 321 can cooperate with the clamping hole 10. Through the cooperation between the plug-in portion 321 and the clamping hole 10, it can be ensured that the workpiece in the storage slot 320 can accurately enter the clamping hole 10, thereby preventing the workpiece from falling out.

[0029] The feeding track 4 includes a fixed plate 41, a baffle 42, and an adjusting column 43. The baffle 42 is mounted on the fixed plate 41, and the adjusting column 43 is slidably mounted on the fixed plate 41 along a second direction. An adjustable-width feeding trough 40 is formed between the adjusting column 43, the baffle 42, and the fixed plate 41. The fixed plate 41 has an oblong hole 410 extending along the second direction, and the adjusting column 43 has a fixing block 431. An adjusting bolt 432 is installed in the fixing block 431 and slidably mounted in the oblong hole 410. By loosening the adjusting bolt 432, the bolt can slide in the oblong hole 410, thereby driving the fixing block 431 to move along the second direction, which in turn drives the adjusting column 43 to move along the second direction. This mechanism enables the spacing of the feeding trough 40 in the second direction to be adjusted, allowing it to accommodate workpieces of different lengths and improving the adaptability of the feeding track 4. After adjustment, the fixing bolt 25 needs to be tightened to fix the adjusting column 43. In addition, the spacing of the feeding trough 40 along the second direction is less than the length of the feed inlet 221 in the same direction.

[0030] The baffle 42 is equipped with a second cylinder 44, which has a second piston rod 441 extending in a second direction. The second piston rod 441 is movably installed in the feeding trough 40 in the second direction. The second piston rod 441 is used to block the workpiece in the feeding trough 40. There is a storage space between the second piston rod 441 and the discharge port 400. The storage space can only accommodate one workpiece to be processed. Therefore, the second piston rod 441 can ensure that only one workpiece can enter the feed port 221 and fall into the storage trough 320 at a time.

[0031] An adjustment assembly is installed on the movable block 22. The adjustment assembly includes a mounting block 23, an adjustment plate 24, and a fixing bolt 25. The adjustment plate 24 has an adjustment groove 240 extending along a first direction. The fixing bolt 25 is installed on the mounting block 23 and is relatively slidably installed in the adjustment groove 240. The second linear drive 31 is fixedly installed on the adjustment plate 24. By adjusting the position of the adjustment plate 24 in the first direction, the position of the second linear drive 31 in the first direction can be adjusted. The adjustment plate 24 and / or the second linear drive 31 and / or the connecting block 32 can be customized according to customer needs to meet the needs of different customers and at a lower cost.

[0032] Specific usage process: First, neatly place the pipe fitting workpiece to be processed into the feeding groove 40 of the feeding track 4. Loosen the adjusting bolt 432 according to the length of the workpiece, and adjust the position of the adjusting column 43 along the oblong hole 410 to make the spacing of the feeding groove 40 fit the workpiece. Then tighten the fixing bolt 25 to fix it. After starting the equipment, the second cylinder 44 drives the second piston rod 441 to extend, blocking subsequent workpieces in the feeding groove 40, so that only a single workpiece in the storage space is in the unloading state. Next, the first linear drive 21 drives the movable block 22 to move along the first direction to the second position. At this time, the discharge port 400 of the loading track 4 corresponds to the inlet 221 of the movable block 22. The workpiece in the storage space enters the connecting channel 220 through the inlet 221 and falls into the storage slot 320 of the connecting block 32 through the discharge port 222. The second linear drive 31 starts and drives the connecting block 32 to move along the second direction toward the machine tool chuck 12 until the insertion part 321 of the connecting block 32 is inserted into the clamping hole 10 of the machine tool chuck 12 and abuts. At this time, the first piston rod 312 of the first cylinder 311 continues to extend and pushes the push plate 33 to continue to move along the second direction, pushing the workpiece in the storage slot 320 out and into the clamping hole 10 of the machine tool chuck 12 to complete the loading. After the material is fed, the second linear drive 31 drives the connecting block 32 to reset, the elastic element 34 pulls the push plate 33 back to the initial position, and the first linear drive 21 drives the movable block 22 to move from the second position to the first position, waiting for the next feeding cycle.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
