[0002] A CNC lathe is a lathe that uses a computer numerical control system to control the lathe's motion and processing. Compared with traditional manual or semi-automatic lathes, it has a higher degree of automation and precision; CNC lathes encode the processing program into digital instructions and input them into the CNC system, which interprets and executes the instructions to control the various axial movements of the lathe and the operation of the tool to achieve workpiece processing. The CNC system is usually composed of a computer and related controllers, drivers, encoders, etc.

[0003] Existing precision hole pitch processing fixtures for CNC lathes are usually designed to clamp small-sized workpieces during hole pitch processing. When it is necessary to clamp a workpiece with a large stroke and perform hole pitch processing, the clamping range of the fixture may not meet the requirements; the clamping length of the fixture is limited and cannot meet the clamping needs of workpieces with a large stroke. At the same time, due to the limited clamping points, the clamping accuracy may not meet the requirements. The workpiece may have problems such as deflection and tilt during the clamping process, resulting in a decrease in hole pitch processing accuracy; therefore, a precision hole pitch processing fixture for CNC lathes is proposed to solve the above problems.

[0026] The linear adjustment assembly 4 includes an adjustment seat 40 disposed on the stand 1, a first screw rod 41 is rotatably disposed inside the adjustment seat 40, and a slider seat 42 is slidably engaged with the first screw rod 41 outside.

[0027] A debris collecting trough 2 is installed on the lower end surface of the stand 1 , and a polished rod 9 is arranged in the debris collecting trough 2 .

[0028] In this embodiment, in actual use, through the movement coordination of the set linear adjustment component 4 and the displacement component 7, the set positioning rod 8 and the two groups of positioning shafts 5 can move relative to each other until the workpiece is clamped and positioned. At the same time, the set positioning shafts 5 and positioning rods 8 can perform long-stroke displacement movements, and then cooperate with each other to achieve multi-point limiting. Through the long-stroke clamping of the set positioning shafts 5 and positioning rods 8, it can adapt to the clamping needs of workpieces of different sizes and strokes. Each group of clamping structures can be independently adjusted and adapted to different workpiece sizes, thereby expanding the clamping range. At the same time, multiple groups of long-stroke clamping can provide more clamping points, making the clamping force more evenly distributed, thereby improving the clamping stability of the CNC lathe during precision hole spacing processing.

[0029] Specifically, refer to Figure 1-3 Bearing grooves are provided at both ends of the adjustment seat 40 and bearing members are installed in the bearing grooves. Both ends of the first screw rod 41 are rotatably matched with the bearing members. One end of the slider seat 42 passes through the adjustment seat 40 and is connected to an adjustment handle 43 outside.

[0030] In this embodiment, in actual use, the user turns the adjusting handle 43 so that the first screw rod 41 can rotate synchronously. At this time, the two bearing members arranged in the adjusting seat 40 can cooperate with the rotation of the first screw rod 41, so that the rotation of the first screw rod 41 is more stable, thereby improving the rotation accuracy of the first screw rod 41. When the first screw rod 41 is rotating, it is limited by the adjusting seat 40, and the provided slider seat 42 can move in a straight line in the adjusting seat 40, thereby driving the positioning shaft 5 to perform synchronous linear displacement to realize the positioning of the workpiece. When the workpiece is undergoing precision hole spacing processing, the two displaced positioning shafts 5 can stably limit one side of the workpiece, and cooperate with the provided positioning rod 8 to achieve stable clamping of the workpiece.

[0031] Specifically, refer to Figure 1-3 The displacement assembly 7 includes a reciprocating motor 71 arranged on the mounting seat 6. The output end of the reciprocating motor 71 is rotatably provided with a second screw rod 72. The second screw rod 72 is externally meshed and slidably provided with a slide seat 73. The slide seat 73 is L-shaped and surrounds the mounting seat 6.

[0032] In this embodiment, in actual use, the user connects a power source to the reciprocating motor 71 to rotate the second screw rod 72. At this time, the sliding seat 73 engaged with the second screw rod 72 will be limited by the mounting seat 6, and then slide linearly outside the mounting seat 6.

[0033] Specifically, refer to Figure 1-3 A slide groove 74 is provided on the upper end surface of the slide seat 73, a positioning rod 8 is slidably arranged in the slide groove 74, and a rubber pad is arranged around the outside of the positioning rod 8.

[0034] In this embodiment, in actual use, when the slide 73 is sliding, the arranged positioning rod 8 can slide on the outside of the mounting seat 6 until one end of the workpiece is tightly pressed against. At this time, the arranged positioning rod 8 cooperates with the two positioning shafts 5 to realize long-stroke clamping and positioning of the workpiece. At the same time, the three-point positioned positioning shaft 5 and the positioning rod 8 can provide more clamping points, so that the clamping force is more evenly distributed, thereby improving the clamping stability of the CNC lathe during precision hole spacing processing.

[0035] Specifically, refer to Figure 1-3 The upper end surface of the stand 1 is also provided with three shaft seats 3, each shaft seat 3 is rotatably provided with a rubber shaft, and the three shaft seats 3 and the mounting seat 6 are dispersed in a rectangular shape and the highest point is horizontally arranged.

[0036] In this embodiment, the shaft seat 3 is provided to support the workpiece, so that when the workpiece is subjected to hole spacing processing, the shaft seat 3 can be used as a support to achieve stable placement of the workpiece.

[0037] Specifically, refer to Figure 4 One end of the polished rod 9 is connected to a scraper 91 , and the scraper 91 slides in the debris collecting groove 2 and abuts against the side wall of the debris collecting groove 2 .

[0038] In this embodiment, by slidingly cooperating with the debris collection groove 2 and the scraper 91, when the workpiece completes the precision hole pitch processing on the CNC lathe, the debris generated by the processing can be directly scraped away, thereby reducing the splashing effect of the debris on the workpiece.

[0039] The utility model is a precision hole distance processing fixture for CNC lathes:

[0040] Step 1: In actual use, the user assembles the platform 1 on the CNC lathe, and then places the workpiece to be processed on the three sets of shaft seats 3. At this time, the workpiece can be loaded by the horizontal setting of the shaft seats 3. Then the user can adjust the displacement assembly 7 to move the positioning rod 8 until the workpiece is tightly clamped;

[0041] Step 2: When adjusting the displacement assembly 7, the user connects the reciprocating motor 71 to a power source, so that the second screw rod 72 is rotated. At this time, the slide 73 meshing with the second screw rod 72 will be limited by the mounting seat 6, and then slide linearly outside the mounting seat 6. When the slide 73 slides, the positioning rod 8 can slide outside the mounting seat 6 until one end of the workpiece is tightly pressed against it.

[0042] Step 3: When the workpiece is tightly pressed by one end of the positioning rod 8, the user can also adjust the two sets of linear adjustment components 4, so that the set positioning shaft 5 can be moved, thereby completing the large-stroke clamping setting. When the linear adjustment component 4 is in use, the user turns the adjustment handle 43, and the set first screw rod 41 will rotate synchronously at this time, and is restricted by the adjustment seat 40 on the slider seat 42, so that the set slider seat 42 can move linearly, thereby completing the position adjustment of the positioning shaft 5. By adjusting the position of the positioning shaft 5, the user can cooperate with the positioning rod 8 to complete the three-point limit of the workpiece, and finally realize multi-point limit of the workpiece.
