Description

Technical Field

[0001] This utility model relates to the field of thread processing technology, specifically to a thread processing device for a high-flow hydraulic quick coupling. Background Technology

[0002] In traditional high-flow hydraulic quick coupling thread processing, the workpiece conveying and positioning methods are outdated. Manual handling is inefficient and has large positioning deviations. Simple mechanical pushing is difficult to position accurately due to structural wear and manufacturing errors, resulting in large deviations in key thread dimensions and a high scrap rate. The cutting mechanism lacks precise drive and adjustment mechanisms, relying on manual or rough transmission, making it difficult to accurately control according to processing requirements. It is highly dependent on worker skills, resulting in large differences in processing quality among different workers. Furthermore, the equipment has poor versatility and is difficult to adapt to the processing of new coupling specifications, often requiring equipment modification or replacement, which increases costs and production cycles. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of high scrap rate due to backward workpiece conveying and positioning, inaccurate control of cutting mechanism and reliance on manual labor, poor equipment versatility and frequent modification in traditional high-flow hydraulic quick coupling thread processing. This utility model provides a thread processing equipment for high-flow hydraulic quick couplings.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A thread processing device for a high-flow hydraulic quick coupling includes a machine tool. Front and rear guardrails are fixedly connected to the front and rear ends of the machine tool. A telescopic rod extends through both sides of the front and rear guardrails. A pushing component is slidably connected to the outer side of the telescopic rod. A support frame is mounted on the top of the pushing component. A pusher component is mounted on the left end of the support frame. A cutting mechanism is fixedly connected to the right end of the pusher component. The rear sidewall of the cutting mechanism is slidably connected to the front end of the support frame. An electric cylinder is mounted on the right end of the machine tool and the front and rear guardrails. A sliding component is slidably connected to the top side of the machine tool. Both sides of the sliding component are fixedly connected to the inner side of the pusher component. The bottom end of the cutting mechanism is located above the sliding component. The cutting mechanism includes a rotary motor, an electric cylinder, and a spiral drill bit. The bottom output end of the rotary motor is fixedly connected to the top end of the electric cylinder, and the top end of the spiral drill bit is fixedly connected to the bottom end of the electric cylinder.

[0006] Furthermore, the pushing component includes a sliding plate and a slot. The inner side of the bottom end of the slot is sleeved on the bottom end of the inner wall of the sliding plate, and the inner side of the bottom end of the slot is slidably connected to the middle of the outer side of the telescopic rod. The inner side of the bottom end of the slot in the pushing component is sleeved on the bottom end of the inner wall of the sliding plate and slides in the middle of the outer side of the telescopic rod, thereby realizing the smooth movement of the pushing component.

[0007] Furthermore, the pushing component includes a linear motor and a second telescopic rod. The output end of the linear motor is internally connected to the outer end of the second telescopic rod, and the inner end of the second telescopic rod is fixedly connected to the outer wall of the cutting mechanism. The output end drives the second telescopic rod to extend and retract, and the inner end of the second telescopic rod is fixedly connected to the outer wall of the cutting mechanism.

[0008] Furthermore, the cutting mechanism also includes a housing, with the rotary motor, the electric cylinder, and the auger drill bit penetrating the inner side of the housing. The outer top end of the auger drill bit penetrates and is slidably connected to the inner bottom end of the housing. When the rotary motor in the cutting mechanism is started, its bottom output end drives the electric cylinder to rotate, thereby driving the auger drill bit, which is fixedly connected to the bottom end of the electric cylinder, to rotate.

[0009] Furthermore, the cutting mechanism also includes an electric cylinder two, a support rod, and an external cutting tool. The top end of the support rod is fixedly connected to the bottom outer end of the electric cylinder two. The bottom end of the support rod and the top side of the external cutting tool are fixedly connected to the bottom end of the support rod. The rear left end of the electric cylinder two is fixedly connected to the front bottom end of the electric cylinder one. When the electric cylinder two is started, the support rod fixedly connected to its bottom outer end moves accordingly, and the external cutting tool fixed at the bottom end of the support rod approaches the workpiece.

[0010] Furthermore, the sliding assembly includes a slide rod, a clamping frame one, a clamping frame two, and a miniature electric cylinder. The front and rear ends of the slide rod are fixedly connected to the front and rear ends of the front and rear guardrails. The electric cylinder three moves in the reverse direction to return the sliding assembly to its initial position. The miniature electric cylinder controls the clamping frame one and the clamping frame two to release.

[0011] Furthermore, the inner sides of both ends of the clamping frame one are slidably connected to the outer side of the slide rod, and the left ends of the clamping frame one and the clamping frame two are movably connected to the outer side wall of the miniature electric cylinder. The inner diameter of the clamping holes of the clamping frame one and the clamping frame two decreases from left to right, so that workpieces of different sizes can be fixedly clamped.

[0012] Furthermore, a control panel is provided on the front side of the front and rear guardrails, through which the device is turned on.

[0013] Compared with the prior art, this utility model provides a thread processing device for high-flow hydraulic quick couplings, which has the following beneficial effects:

[0014] This high-flow hydraulic quick-connect thread processing equipment uses a three-drive electric cylinder sliding assembly that slides on the top side of the machine tool. Combined with the fixed connection between the sliding assembly and the pushing assembly, it can precisely transport the workpiece to the designated processing position, ensuring accurate workpiece positioning and thus improving thread processing precision and reducing scrap rates caused by positioning deviations. The pushing assembly can precisely control the cutting mechanism to slide along the support frame, ensuring that the cutting mechanism can stably approach and move away from the workpiece during processing, further improving processing accuracy and operational controllability. It can precisely control the feed depth of the auger drill bit according to processing requirements. This design can flexibly handle internal thread drilling of high-flow hydraulic quick-connect couplings of different specifications, improving the equipment's versatility and processing accuracy.

Example:

[0023] like Figures 1-6 As shown, a thread processing device for a high-flow hydraulic quick coupling includes a machine tool 1. Front and rear guardrails 2 are fixedly connected to the front and rear ends of the machine tool 1. Telescopic rods 3 extend through both sides of the front and rear guardrails 2. A pushing component 4 is slidably connected to the outer side of the telescopic rods 3. A support frame 5 is provided at the top of the pushing component 4. A push component 6 is provided at the left end of the support frame 5. A cutting mechanism 7 is fixedly connected to the right end of the push component 6. The rear side wall of the cutting mechanism 7 is slidably connected to the front end of the support frame 5. An electric cylinder 3 8 is provided at the right end of the machine tool 1 and the front and rear guardrails 2. A sliding component 9 is slidably connected to the top side of the machine tool 1. Both sides of the sliding component 9 are fixedly connected to the inner side of the push component 4. The bottom end of the cutting mechanism 7 is located above the sliding component 9. A control panel 10 is provided at the front side of the front and rear guardrails 2.

[0024] like Figure 2 As shown, the pushing component 4 includes a slide plate 41 and a slot 42. The inner side of the bottom end of the slot 42 is sleeved on the bottom end of the inner wall of the slide plate 41. The inner side of the bottom end of the slot 42 is slidably connected to the middle of the outer side of the telescopic rod 3. The telescopic rod 3 drives the pushing component 4 to slide along its outer side through the telescopic movement. The inner side of the bottom end of the slot 42 in the pushing component 4 is sleeved on the bottom end of the inner wall of the slide plate 41 and slides in the middle of the outer side of the telescopic rod 3, thereby realizing the smooth movement of the pushing component 4. The support frame 5 at the top of the pushing component 4 moves with the pushing component 4 and transports the cutting mechanism 7 to the vicinity of the workpiece.

[0025] like Figure 2 , Figure 3 As shown, the pushing component 6 includes a linear motor 61 and a telescopic rod 62. The output end of the linear motor 61 is internally connected to the outer end of the telescopic rod 62, and the inner end of the telescopic rod 62 is fixedly connected to the outer wall of the cutting mechanism 7, thereby pushing the cutting mechanism 7 to slide along the front end of the support frame 5, so that the cutting mechanism 7 is close to the workpiece.

[0026] like Figures 3-5As shown, the cutting mechanism 7 includes a rotary motor 72, an electric cylinder 73, and a spiral drill bit 74. The bottom output end of the rotary motor 72 is fixedly connected to the top end of the electric cylinder 73, and the top end of the spiral drill bit 74 is fixedly connected to the bottom end of the electric cylinder 73. The cutting mechanism 7 also includes a housing 71. The rotary motor 72, electric cylinder 73, and spiral drill bit 74 pass through the inner side of the housing 71. The outer top end of the spiral drill bit 74 passes through and is slidably connected to the inner bottom end of the housing 71. The cutting mechanism 7 also includes an electric cylinder 75, a support rod 76, and an external cutting tool 77. The top end of the support rod 76 is fixedly connected to the outer bottom end of the electric cylinder 75, and the bottom end of the support rod 76... The top side of the external cutting tool 77 and the bottom end of the support rod 76 are fixedly connected. The rear left end of the electric cylinder 2 75 is fixedly connected to the front bottom end of the electric cylinder 1 73. When the rotary motor 72 in the cutting mechanism 7 starts, its bottom output end drives the electric cylinder 1 73 to rotate, which in turn drives the spiral drill bit 74 fixedly connected to the bottom end of the electric cylinder 1 73 to rotate. At the same time, the electric cylinder 1 73 starts, pushing the spiral drill bit 74 to move downward to perform internal thread drilling on the workpiece. The outer top end of the spiral drill bit 74 passes through and slides to the inner bottom end of the housing 71. The housing 71 provides protection and support for the rotary motor 72, the electric cylinder 1 73 and the spiral drill bit 74.

[0027] like Figure 6 As shown, the sliding assembly 9 includes a slide rod 91, a clamping frame 1 92, a clamping frame 2 93, and a miniature electric cylinder 94. The front and rear ends of the slide rod 91 are fixedly connected to the front and rear ends of the front and rear guardrails 2. The inner sides of both ends of the clamping frame 1 92 are slidably connected to the outer sides of the slide rod 91. The left ends of the clamping frame 1 92 and the clamping frame 2 93 are movably connected to the outer side wall of the miniature electric cylinder 94. The inner diameter of the clamping holes of the clamping frame 1 92 and the clamping frame 2 93 decreases from left to right, which can fix and clamp workpieces of different sizes.

[0028] Working principle: such as Figures 1-6 As shown, equipment startup and preparation: The operator turns on the equipment via control panel 10;

[0029] Workpiece conveying and positioning: When the electric cylinder 38 is activated, it pushes the sliding assembly 9 to slide on the top side of the processing machine tool 1. In the sliding assembly 9, the front and rear ends of the slide rod 91 are fixed to the front and rear ends of the front and rear guardrails 2, providing sliding tracks for the clamping frame 1 92 and the clamping frame 2 93. When the micro electric cylinder 94 is activated, it controls the opening and closing of the clamping frame 1 92 and the clamping frame 2 93, thereby clamping the workpiece. Under the push of the electric cylinder 38, the sliding assembly 9 holding the workpiece conveys the workpiece to the appropriate processing position.

[0030] Pushing and adjusting the cutting mechanism 7: The telescopic rod 3 drives the pushing component 4 to slide along its outer side through the telescopic action. The inner side of the bottom end of the slot 42 in the pushing component 4 is sleeved on the bottom end of the inner wall of the slide plate 41 and slides in the middle of the outer side of the telescopic rod 3, thereby realizing the smooth movement of the pushing component 4. The support frame 5 at the top of the pushing component 4 moves with the pushing component 4 and transports the cutting mechanism 7 to the vicinity of the workpiece.

[0031] Cutting and processing process:

[0032] Internal thread processing: The linear motor 61 in the push assembly 6 is started, and its output end drives the extension rod 62 to extend and retract. The inner end of the extension rod 62 is fixedly connected to the outer wall of the cutting mechanism 7, thereby pushing the cutting mechanism 7 to slide along the front end of the support frame 5, so that the cutting mechanism 7 is close to the workpiece.

[0033] When the rotary motor 72 in the cutting mechanism 7 is started, its bottom output end drives the electric cylinder 73 to rotate, which in turn drives the spiral drill bit 74, which is fixedly connected to the bottom of the electric cylinder 73, to rotate. At the same time, the electric cylinder 73 is started, pushing the spiral drill bit 74 to move downward to drill the internal thread of the workpiece. The outer top of the spiral drill bit 74 passes through and is slidably connected to the inner bottom of the housing 71. The housing 71 provides protection and support for the rotary motor 72, the electric cylinder 73 and the spiral drill bit 74.

[0034] External thread machining: After the internal drilling is completed, the electric cylinder 2 75 is started, and the support rod 76 fixedly connected to its bottom outer end moves accordingly. The external cutting tool 77 fixed at the bottom end of the support rod 76 approaches the workpiece. Under the rotation of the electric cylinder 1 73 driven by the rotary motor 72, the external cutting tool 77 rotates around the workpiece to perform external thread cutting on the workpiece.

[0035] Processing completion and reset: After the thread processing is completed, electric cylinder 1 73 and electric cylinder 2 75 retract, causing the spiral drill bit 74 and the external cutting tool 77 to move away from the workpiece. The linear motor 61 drives the telescopic rod 2 62 to retract, causing the cutting mechanism 7 to return to the initial position. The telescopic rod 1 3 retracts, driving the pushing component 4 to return to the initial position. Electric cylinder 3 8 reverses its action, causing the sliding component 9 to return to the initial position. The micro electric cylinder 94 controls the clamping frame 1 92 and clamping frame 2 93 to release, allowing the operator to remove the processed workpiece.

[0036] The inner diameter of the inner clamping holes of clamping frame 1 92 and clamping frame 2 93 decreases from left to right, which can be used to fix and clamp workpieces of different sizes.
