Description

Technical Field

[0001] This invention belongs to the field of livestock feeding equipment manufacturing technology, specifically, it relates to an electric plug processing device and its working method. Background Technology

[0002] In US standard plugs, the grounding pin is typically cylindrical. For example... Figure 1 The cylindrical pin shown is first cut from a cylindrical bar, and then one section is chamfered (1a) while the other section is machined with a wire hole. However, in the prior art, the cutting and chamfering of the cylindrical bar are usually separated into two processes, which greatly reduces the production efficiency of cylindrical pin processing. Therefore, we propose an electrical pin processing equipment and its working method. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an electrical pin processing device that can overcome the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: an electric plug processing device includes a table, on which four vertically arranged guide rods are fixedly mounted, and a horizontal plate is slidably connected to the four guide rods along the vertical direction; a left protrusion and a right protrusion are provided on the table below the horizontal plate, a left rotating ring is rotatably connected inside the left protrusion, and a right rotating ring is rotatably connected inside the right protrusion, a left chuck is fixedly mounted on the right end of the left rotating ring, and a right chuck is fixedly mounted on the left end of the right rotating ring, the left and right chucks are coaxially positioned for clamping cylindrical material bars; a cutting and chamfering assembly is fixedly mounted on the horizontal plate, and the left protrusion contains a... The locking assembly connected to the left-turning ring is fixed relative to the left protrusion when the locking assembly is in the locked position, and can rotate relative to the left protrusion when the locking assembly is in the unlocked position. The horizontal plate is used to control the locking assembly to be in the unlocked or locked position. When the horizontal plate is at the upper stop position, the locking assembly is in the unlocked position. As the horizontal plate moves downward, the cutting and chamfering assembly first cuts the cylindrical bar. After the cutting and chamfering assembly cuts the cylindrical bar, as the horizontal plate continues to move downward, the horizontal plate controls the locking assembly to be in the unlocked position. When the horizontal plate continues to move downward, the cutting and chamfering assembly chamfers the cut end face of the cylindrical bar.

[0005] Furthermore, the cutting and chamfering assembly includes a rotating shaft, which is rotatably connected to a horizontal plate and has a cutting blade fixedly mounted on its right end. A grinding block is fixedly mounted on the rotating shaft on the left side of the cutting blade, and a grinding cone surface is provided on the left end of the grinding block. A first power assembly for driving the rotating shaft to rotate is provided on the horizontal plate. The cutting blade is used to cut the cylindrical bar, and the grinding cone surface is used to grind the cut end face of the cylindrical bar to form a chamfer. During the downward movement of the horizontal plate, the cutting blade first cuts the cylindrical bar, and then the grinding cone surface grinds the cut end face of the cylindrical bar to form a chamfer.

[0006] Furthermore, the first power assembly includes a first motor, which is fixedly mounted on a horizontal plate and located at the right end of the horizontal plate. A first pulley is fixedly mounted on the output shaft of the first motor, and a second pulley is fixedly mounted on the rotating shaft at the left end of the grinding block. A transmission belt is provided between the first pulley and the second pulley.

[0007] Furthermore, the horizontal plate has a mounting groove on the outside of the rotating shaft, and a bevel gear connected to the rotating shaft is provided in the mounting groove. The bevel gear is fixedly connected to the rotating shaft circumferentially and slidably connected to the rotating shaft axially. A first spring for forcing the bevel gear to move to the right is provided in the mounting groove, and a bevel gear ring for meshing with the bevel gear is provided at the left end of the right chuck. After the horizontal plate moves downward and the cutting blade cuts the cylindrical bar, the horizontal plate moves downward. Before the locking assembly is in the unlocked position and the grinding cone surface contacts the cut end face of the cylindrical bar, the bevel gear meshes with the bevel gear ring. As the horizontal plate moves downward, the bevel gear moves to the left along the rotating shaft to compress the first spring, and the bevel gear and the bevel gear ring remain engaged.

[0008] Furthermore, the locking assembly includes a rotating ring block. The left protrusion has a left-turning hole on the left side of the left rotating ring. The rotating ring block is rotatably connected within the left-turning hole and fixedly connected to the left end of the left rotating ring. Locking holes are evenly spaced on the outer circumference of the rotating ring block. The left protrusion has symmetrically arranged vertical sliding holes on both its front and rear sides, as well as horizontal sliding holes connecting the vertical sliding holes and the left-turning hole. A limiting groove is provided below each horizontal sliding hole along the axial direction of the horizontal sliding hole. A sliding block is slidably connected within each horizontal sliding hole, and a limiting protrusion located within the limiting groove is fixedly provided on each sliding block. Each moving block is provided with a locking pin for insertion into the locking hole; each vertical sliding hole is slidably connected with a vertical sliding rod, the vertical sliding rod has a vertical groove on the outer side near the upper end, and the lower section of each vertical groove has a transition slope; each limiting sliding groove is provided with a second spring for forcing the limiting protrusion to drive the sliding block to abut against the vertical sliding rod; when the sliding block abuts against the outer side of the vertical sliding rod, the sliding block drives the locking pin to insert into the locking hole, the rotating block is locked and fixed relative to the left protrusion; when the sliding block abuts against the vertical groove, the sliding block drives the locking pin to disengage from the locking hole, and the rotating block can rotate relative to the left protrusion.

[0009] Furthermore, a connecting crossbar is fixed between the lower ends of the two vertical slide rods, and a tension spring is provided between the connecting crossbar and the tabletop. The tension spring is used to force the connecting crossbar to drive the vertical slide rods to move upward. Each vertical slide rod is provided with a limiting block below the tabletop. When the vertical slide rod is in the upper position, the limiting block abuts against the lower end surface of the tabletop, and the sliding block abuts against the outside of the vertical slide rod. When the vertical slide rod is in the lower position, the sliding block abuts against the vertical groove.

[0010] Furthermore, when the horizontal plate is at its upper limit, the vertical slide bar is at its upper end under the action of the tension spring. When the sliding block abuts against the outside of the vertical slide bar, the sliding block drives the locking pin to insert into the locking hole. As the horizontal plate moves downward, the cutting and chamfering assembly first cuts the cylindrical bar. After the cutting and chamfering assembly cuts the cylindrical bar, as the horizontal plate continues to move downward, the horizontal plate abuts against the upper end of the vertical slide bar and drives the vertical slide bar downward. When the vertical slide bar moves downward and the sliding block abuts against the vertical groove, the sliding block, under the action of the second spring, drives the locking pin to completely disengage from the locking hole. At this time, as the horizontal plate moves downward, the cutting and chamfering assembly chamfers the cut end face of the cylindrical bar. When the horizontal plate moves upward from its lower limit, the vertical slide bar moves upward under the action of the tension spring. As the vertical slide bar moves upward, the sliding block abuts against the outside of the vertical slide bar through the transition slope from the vertical groove, and the locking pin inserts into the locking hole.

[0011] Furthermore, the outer side of the swivel block is provided with a guide cone at the opening of each locking hole so that the locking pin can be inserted into the locking hole.

[0012] The present invention also provides a method for operating the above-mentioned electrical pin processing equipment, comprising the following steps:

[0013] First, control the horizontal plate to the top stop position, at which point the locking component is in the locked position. Then, pass the cylindrical bar from left to right through the left and right rotating rings and measure the required cutting length. Next, control the left and right chucks to clamp the cylindrical bar. Then, start the cutting and chamfering component and control the horizontal plate to move downwards. As the horizontal plate moves downwards, the cutting and chamfering component first cuts the cylindrical bar. After the cutting and chamfering component cuts the cylindrical bar, as the horizontal plate moves downwards, the horizontal plate controls the locking component to the unlocked position. The horizontal plate continues to move downwards, and the cutting and chamfering component chamfers the cut end face of the cylindrical bar. When the horizontal plate moves to the bottom stop position, the cut end face of the cylindrical bar is chamfered, and the cutting and chamfering component stops. Next, control the horizontal plate to drive the cutting and chamfering component to move upwards, and the locking component switches from the unlocked position to the locked position. When the horizontal plate moves to the top stop position, control the left and right chucks to release the cylindrical bar and continue to move the cylindrical bar to the right to the set length, repeating the above steps.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By setting a locking component, a cutting and chamfering component, and a horizontal plate, the present invention can greatly improve the processing efficiency of cylindrical feed bars for livestock feeding equipment by controlling the horizontal plate to move from the upper stop point to the lower stop point to complete the cutting of the cylindrical feed bar and the grinding and chamfering of the cut end face of the cylindrical feed bar. In addition, by setting a bevel gear that can slide left and right relative to the rotating shaft on the rotating shaft, and setting a bevel gear ring on the right chuck, when the horizontal plate moves downward to chamfer the cut end face of the cylindrical feed bar, the rotating shaft drives the cylindrical feed bar to rotate through the bevel gear, bevel gear ring, and right chuck, thereby making the grinding cone face grind and chamfer the cut end face of the cylindrical feed bar more uniform.

[0030] In this embodiment, both the left chuck 8 and the right chuck 9 belong to the prior art applied to lathes.

[0031] The present invention also provides a method for operating the above-mentioned electrical pin processing equipment, comprising the following steps:

[0032] First, the second motor 30 is controlled to drive the threaded rod 31 to rotate. The threaded rod 31 drives the horizontal plate 3 to the upper stop position. At this time, the locking assembly is in the locked position, that is, the sliding block 21 abuts against the outside of the vertical sliding rod 24 and the sliding block 21 drives the locking pin 23 to insert into the locking hole 20a. Then, the cylindrical bar passes from left to right through the left rotating ring 6 and the right rotating ring 7 and the required cutting length is measured. Next, the left chuck 8 and the right chuck 9 are controlled to clamp the cylindrical bar. Then, the cutting and chamfering assembly is started, that is, the first motor 13 is started to drive the first pulley 14 to rotate. The first pulley 14 drives the second pulley 15 to rotate through the transmission belt 16. The second pulley 15 drives the rotating shaft 10 and the cutting blade 11, grinding block 12 and bevel gear 17 connected to the rotating shaft 10 to rotate synchronously. The second motor 30 is controlled to drive the threaded rod 31 to rotate. The threaded rod 31 drives the horizontal plate 3 to move downward. As the horizontal plate 3 moves downward, the cutting blade 11 first cuts the cylindrical bar. Cutting is performed. After the cutting blade 11 cuts the cylindrical bar, the horizontal plate 3 moves downward and abuts against the upper end of the vertical slide bar 24. At this time, the horizontal plate 3 pushes the vertical slide bar 24 downward. When the sliding block 21, under the action of the first spring 18, abuts against the vertical cutting groove 24a after passing through the transition slope 24b, the locking pin 23 completely disengages from the locking hole 20a. As the horizontal plate 3 continues to move downward, the bevel gear 17 meshes with the bevel gear ring 19. The bevel gear 17 drives the cylindrical bar to rotate through the bevel gear ring 19 and the right chuck 9. The horizontal plate 3 moves downward, and the grinding cone surface 12a contacts the cutting end face of the cylindrical bar to grind the cutting end face of the cylindrical bar to form a chamfer. At the same time, the bevel gear 17 moves to the left along the rotating shaft 10 and compresses the second spring 25. When the horizontal plate 3 moves to the lower stop point, the cutting end face of the cylindrical bar is chamfered, and the cutting chamfering assembly is stopped, that is, the first motor 13 is stopped rotating.

[0033] Next, the second motor 30 is reversed. The second motor 30 drives the horizontal plate 3 to move upward through the threaded rod 31. The horizontal plate 3 drives the cutting and chamfering assembly to move upward. As the horizontal plate 3 moves upward, the vertical slide bar 24 moves upward under the action of the tension spring 27. The sliding block 21 abuts against the outside of the vertical slide bar 24 after passing through the vertical groove 24a and the transition slope 24b. At this time, the sliding block 21 drives the locking pin 23 to insert into the locking hole 20a. The locking assembly switches from the unlocked position to the locked position. When the horizontal plate 3 is completely separated from the upper end of the vertical slide bar 24, the limiting block 28 abuts against the lower end surface of the table plate 1. When the horizontal plate 3 moves to the upper stop position, the left chuck 8 and the right chuck release the cylindrical bar and continue to move the cylindrical bar to the right to the set length. The above steps are repeated.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

When the vertical slide bar moves downward and the sliding block abuts against the vertical groove, the sliding block, under the action of the second spring, drives the locking pin to completely disengage from the locking hole. At this time, as the horizontal plate moves downward, the cutting and chamfering assembly chamfers the cut end face of the cylindrical bar. When the horizontal plate moves upward from its lower limit, the vertical slide bar moves upward under the action of the tension spring. As the vertical slide bar moves upward, the sliding block abuts against the outside of the vertical slide bar from the vertical groove through the transition slope, and the locking pin inserts into the locking hole.

6. The electrical connector processing equipment according to claim 1, characterized in that, The outer side of the swivel block is provided with a guide cone at the opening of each locking hole so that the locking pin can be inserted into the locking hole.

7. A method of operating the electrical connector processing equipment according to claim 1, characterized in that, Includes the following steps: First, control the horizontal plate to the top stop position, at which point the locking component is in the locked position. Then, pass the cylindrical bar from left to right through the left and right rotating rings and measure the required cutting length. Next, control the left and right chucks to clamp the cylindrical bar. Then, start the cutting and chamfering component and control the horizontal plate to move downwards. As the horizontal plate moves downwards, the cutting and chamfering component first cuts the cylindrical bar. After the cutting and chamfering component cuts the cylindrical bar, as the horizontal plate moves downwards, the horizontal plate controls the locking component to the unlocked position. The horizontal plate continues to move downwards, and the cutting and chamfering component chamfers the cut end face of the cylindrical bar. When the horizontal plate moves to the bottom stop position, the cut end face of the cylindrical bar is chamfered, and the cutting and chamfering component stops. Next, control the horizontal plate to drive the cutting and chamfering component to move upwards, and the locking component switches from the unlocked position to the locked position. When the horizontal plate moves to the top stop position, control the left and right chucks to release the cylindrical bar and continue to move the cylindrical bar to the right to the set length, repeating the above steps.
