Description

Technical Field

[0001] This invention relates to the field of worm shaft processing equipment technology, specifically to a high-precision worm shaft deburring machine that is easy to adjust. Background Technology

[0002] Worm shafts, as common transmission components, often develop burrs during machining. These burrs not only affect the appearance and quality of the worm shaft but also severely impact transmission efficiency during use. Therefore, deburring is an essential step in worm shaft machining. Currently, burrs are primarily removed using deburring machines. Existing deburring machines typically use a grinding wheel mechanism to deburr worm shafts. However, the structure of this grinding wheel mechanism is flawed. It cannot adjust the pitch angle of the grinding wheel drive motor during operation, resulting in limited applicability and making it unsuitable for worm shafts of different sizes. Furthermore, because the grinding wheel mechanism uses a cylinder for lifting and lowering control, it suffers from low motion accuracy and poor stability. Moreover, since the cylinder typically has a fixed stroke, it cannot automatically compensate for the position of the grinding wheel when it wears, further reducing the machining accuracy of the product.

[0003] Chinese patent CN106826443B discloses an automatic deburring machine for worm shafts. The machine uses a pushing cylinder and a pushing rod to push the worm shaft onto a feeding belt. The feeding belt then transports the worm shaft to the workpiece clamping position. A lifting cylinder pushes the top block to raise the worm shaft. When the worm shaft rises to a certain height, it contacts the V-belt. The V-belt then drives the worm shaft to rotate, while simultaneously controlling the grinding wheel assembly to approach the worm shaft for grinding.

[0004] This solution uses the cooperation of a lead screw and a motor to enable convenient and precise position adjustment of the grinding wheel assembly within a certain range. However, during deburring, some sections of the worm shaft contact the top material block, and some sections of the worm shaft are not in the middle section. As a result, the worm shaft part of the worm shaft will contact the top material block, making it impossible for the grinding wheel assembly to contact the worm shaft part and perform deburring, regardless of how it is adjusted. If the position is adjusted before the worm shaft is loaded, firstly, each adjustment takes time and effort, reducing the efficiency of the entire deburring process; secondly, long-term repetitive work can cause the operator to lose focus, easily leading to incorrect worm shaft position adjustment, resulting in some worm shafts being output outside the equipment without completing the deburring process. Summary of the Invention

[0005] To address the aforementioned issues, a high-precision worm shaft deburring machine that is easy to adjust is provided. The worm shaft position is detected by a detection plate before it enters the feed belt, and the position of the worm shaft is adjusted by a movable frame and a first U-shaped frame if it is incorrectly positioned.

[0006] To address the problems of existing technologies, a high-precision worm gear deburring machine that is easy to adjust is provided.

The detection plate is slidably disposed between the two vertical bars of the first U-shaped frame. The sliding direction of the detection plate is parallel to the center line connecting the two vertical bars in the first U-shaped frame. The detection plate can contact the worm shaft passing through the movable frame and detect the worm part of the worm shaft. When the worm part of the worm shaft moves away from the grinding wheel assembly, the first U-shaped frame drives the worm shaft to rotate 180° through the detection plate.

[0007] Preferably, the first U-shaped frame further includes a first spring. A fixing rod is fixedly installed between the two longitudinal bars of the first U-shaped frame. The axis of the fixing rod is horizontal and perpendicular to the transport direction of the feed belt. There are several detection plates, all of which are slidably engaged with the fixing rod. All the detection plates are evenly arranged along the axial direction of the fixing rod and are in contact with each other. The detection plates cover more than 3 / 4 of the length of the fixing rod. One end of the first spring is fixedly installed on the two longitudinal bars of the first U-shaped frame. The other end of the first spring extends towards the detection plate along the axial direction of the fixing rod. The bottom end of the detection plate is provided with a beveled protrusion that can be inserted into the worm portion of the worm shaft. A light sensor connected to the servo motor signal is fixedly installed on the fixing rod. The light sensor is located at the end away from the grinding wheel assembly.

[0008] Preferably, the feeding assembly further includes a second U-shaped frame, which consists of a horizontal bar and two vertical bars. The detection plate is slidably disposed between the two vertical bars of the second U-shaped frame. The sliding direction of the detection plate is parallel to the extension direction of the vertical bars on the second U-shaped frame. A second spring is fixedly disposed on the top of the detection plate. The end of the second spring away from the detection plate is fixedly connected to the horizontal bar of the second U-shaped frame. A long groove is provided on the detection plate to slide with the fixed rod. The length direction of the long groove is parallel to the extension direction of the vertical bars on the second U-shaped frame.

[0009] Preferably, a first limiting groove is provided on the crossbar of the first U-shaped frame, and the length direction of the first limiting groove is parallel to the line connecting the centers of the two longitudinal bars of the first U-shaped frame. A first limiting protrusion is fixedly provided on the crossbar of the second U-shaped frame to slide in cooperation with the first limiting groove.

[0010] Preferably, a movable ring is movably sleeved on the fixed rod, the movable ring slides along the axial direction of the fixed rod, the movable ring contacts the detection plate, and the end of the first spring away from the longitudinal bar on the first U-shaped frame is fixedly connected to the movable ring.

[0011] Preferably, the detection plate is provided with a second limiting groove, the length direction of the second limiting groove is parallel to the sliding direction of the detection plate, and a second limiting protrusion is fixedly provided on the longitudinal bar of the second U-shaped frame to slide in cooperation with the second limiting groove.

[0012] Preferably, the feeding assembly further includes a movable plate, which is disposed inside the movable frame and is horizontally positioned. A fixed shaft extending downward in a vertical direction is fixedly disposed on the bottom surface of the movable plate. A through hole is provided on the frame to slide with the fixed shaft. A third spring is sleeved on the fixed shaft. One end of the third spring is fixedly connected to the frame, and the other end of the third spring is fixedly connected to the movable plate. A third limiting groove is provided on the side of the movable plate. The length direction of the third limiting groove is parallel to the transport direction of the feeding belt. A third limiting protrusion is fixedly disposed on the movable frame to slide with the third limiting groove. When the movable frame contacts the feeding belt, the movable frame moves with the feeding belt.

[0013] Preferably, a third spring is fixedly provided at the end of the third limiting groove away from the push plate, and the other end of the third spring is fixedly connected to the third limiting protrusion.

[0014] Preferably, the top and bottom surfaces of the movable frame do not overlap.

[0015] Preferably, two limiting strips for limiting the position of the worm shaft are fixedly provided on the fixed plate, and the length direction of the limiting strips is parallel to the transport direction of the feed belt.

[0016] The advantages of this invention compared to the prior art are:

[0017] This invention enables the detection of the worm shaft's position before it enters the feed belt via a detection plate. It also enables the adjustment of incorrectly positioned worm shafts via a movable frame and a first U-shaped bracket. This allows the worm shaft to be directly placed in the fixed plate, making it suitable for deburring different types of worm shafts without requiring manual adjustment of the worm shaft position during each feeding. Furthermore, it ensures that all worm shafts entering the feed belt are deburred before leaving the equipment. Attached Figure Description

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figures 1-10 As shown, an easily adjustable high-precision worm gear deburring machine includes a frame 1, a feeding assembly 2, a feeding belt 3, a limiting seat 4, and a grinding wheel assembly 5. The feeding assembly 2 includes a fixed plate 21, a movable frame 22, a first U-shaped frame 23, and a detection plate 24. The fixed plate 21 is fixedly disposed at one end of the frame 1. A push plate 211 is slidably disposed on the fixed plate 21. The sliding direction of the push plate 211 is parallel to the transport direction of the feeding belt 3. The push plate 211 is fixedly connected to the output end of the cylinder 212. The movable frame 22 is disposed on the fixed plate 21 near one end of the grinding wheel assembly 5. The worm gear shaft placed on the fixed plate 21 can pass through the movable frame 22 under the push of the push plate 211. The axis of the worm gear shaft passing through the movable frame 22 is horizontal and parallel to the axis of the moving frame 22. The conveying direction of the feeding belt 3 is vertical. The first U-shaped frame 23 consists of one horizontal bar and two vertical bars. The horizontal bar of the first U-shaped frame 23 is rotatably connected to the inner top surface of the movable frame 22. The two vertical bars of the first U-shaped frame 23 point to the bottom surface of the movable frame 22. The first U-shaped frame 23 is fixedly connected to the output end of the servo motor 231. The detection plate 24 is slidably disposed between the two vertical bars of the first U-shaped frame 23. The sliding direction of the detection plate 24 is parallel to the center line connecting the two vertical bars in the first U-shaped frame 23. The detection plate 24 can contact the worm shaft passing through the movable frame 22 and detect the worm part of the worm shaft. When the worm part of the worm shaft moves away from the grinding wheel assembly 5, the first U-shaped frame 23 drives the worm shaft to rotate 180° through the detection plate 24.

[0032] The worm shaft is placed on the moving path of the push plate 211. The cylinder 212 is activated, causing the push plate 211 to push the worm shaft to below the top surface of the movable frame 22. At this time, the detection plate 24 will contact the worm shaft and detect the position of the worm portion. When the detection plate 24 detects that the worm portion of the worm shaft is away from the grinding wheel assembly 5, the first U-shaped frame 23 will drive the worm shaft to rotate 180° under the operation of the servo motor 231. At this time, the cylinder 212 will work again to drive the push plate 211 to move, so that the rotated worm shaft moves onto the feeding belt 3. If the worm portion of the worm shaft that has moved to below the top surface of the movable frame 22 is far from the limit... When the worm shaft is in position 4, the first U-shaped frame 23 does not rotate. The push plate 211 pushes the worm shaft onto the feeding belt 3. Compared with the prior art, the detection plate 24 of the present invention detects the position of the worm shaft before it enters the feeding belt 3. The movable frame 22 and the first U-shaped frame 23 adjust the position of the worm shaft if it is not in the correct position. This allows the worm shaft to be placed directly in the fixed plate 21. This is suitable for deburring different types of worm shafts and eliminates the need for manual adjustment of the worm shaft position each time it is loaded. It also ensures that all worm shafts entering the feeding belt 3 can be deburred before leaving the entire equipment.

[0033] See Figures 6-10 As shown: The first U-shaped frame 23 also includes a first spring 232. A fixing rod 233 is fixedly arranged between the two longitudinal bars of the first U-shaped frame 23. The axis of the fixing rod 233 is horizontal and perpendicular to the transport direction of the feeding belt 3. There are several detection plates 24. All detection plates 24 are slidably engaged with the fixing rod 233. All detection plates 24 are evenly arranged along the axial direction of the fixing rod 233 and in contact with each other. The detection plates 24 cover more than 3 / 4 of the length of the fixing rod 233. One end of the first spring 232 is fixedly arranged on the two longitudinal bars of the first U-shaped frame 23. The other end of the first spring 232 extends towards the detection plate 24 along the axial direction of the fixing rod 233. The bottom end of the detection plate 24 is provided with a sloping protrusion that can be inserted into the worm portion of the worm shaft. A light sensor 234 connected to the servo motor 231 is fixedly arranged on the fixing rod 233. The light sensor 234 is located at the end away from the grinding wheel assembly 5.

[0034] The push plate 211 pushes the worm shaft to move below the top surface of the movable frame 22. When the worm shaft is not in contact with the detection plate 24, the first spring 232 is in its normal state and pushes all the detection plates 24 closer to each other. When the worm shaft contacts the detection plate 24, the inclined protrusion on the detection plate 24 engages with the worm portion of the worm shaft and clamps the entire worm shaft. The detection plates 24 engaged with the worm portion of the worm shaft will move away from each other and no longer move closer. The first spring 232 is compressed. If the position of the mutually disengaged detection plates 24 is far away from the grinding wheel assembly 5, the light sensor 234 is unobstructed. The light sensor 234 controls the servo motor 231 to work through the controller to drive the first U-shaped frame 23 to rotate. After the worm shaft disengages from the detection plate 24, the light sensor 234 is obstructed again. The servo motor 231 controls the first U-shaped frame 23 to reverse back to the initial state. Compared with the prior art, the present invention has multiple detection plates 24. The first spring 232 and the light sensor 234 work together to clamp the worm shaft before it rotates, thus ensuring that only the positions of the two ends of the worm shaft are reversed after rotation.

[0035] See Figure 6 , Figure 9 and Figure 10 As shown: The feeding assembly 2 also includes a second U-shaped frame 25, which consists of a horizontal bar and two vertical bars. The detection plate 24 is slidably disposed between the two vertical bars of the second U-shaped frame 25. The sliding direction of the detection plate 24 is parallel to the extension direction of the vertical bars on the second U-shaped frame 25. A second spring 241 is fixedly disposed on the top of the detection plate 24. The end of the second spring 241 away from the detection plate 24 is fixedly connected to the horizontal bar of the second U-shaped frame 25. A long strip groove 242 is provided on the detection plate 24 to slide in cooperation with the fixed rod 233. The length direction of the long strip groove 242 is parallel to the extension direction of the vertical bars on the second U-shaped frame 25.

[0036] Some worm shafts have multiple segments with different diameters. After the detection plate 24 comes into contact with the segment with the larger diameter on the worm shaft, it will slide relative to the second U-shaped frame 25 and retract into the second U-shaped frame 25. Compared with the prior art, the second U-shaped frame 25 of the present invention allows the detection plate 24 to slide in the vertical direction, so that all worm shafts can pass under the detection plate 24.

[0037] See Figure 6 , Figure 9 and Figure 10 As shown: A first limiting groove 235 is provided on the horizontal bar of the first U-shaped frame 23. The length direction of the first limiting groove 235 is parallel to the line connecting the centers of the two vertical bars of the first U-shaped frame 23. A first limiting protrusion 251 that slides and engages with the first limiting groove 235 is fixedly provided on the horizontal bar of the second U-shaped frame 25.

[0038] Compared with the prior art, the first limiting groove 235 and the first limiting protrusion 251 of the present invention limit the state of the second U-shaped frame 25, thereby ensuring that the detection plate 24 will not cause the second U-shaped frame 25 to rotate after it comes into contact with the section with a larger diameter on the worm shaft.

[0039] See Figure 6 , Figure 9 and Figure 10 As shown: A movable ring 236 is movably sleeved on the fixed rod 233. The movable ring 236 slides along the axial direction of the fixed rod 233 and contacts the detection plate 24. The end of the first spring 232 away from the longitudinal bar on the first U-shaped frame 23 is fixedly connected to the movable ring 236.

[0040] Compared to the prior art, the movable ring 236 of the present invention transmits the elastic force of the first spring 232 to the detection plate 24 at the end, thereby ensuring that the elastic force of the first spring 232 is always in a horizontal state.

[0041] See Figure 6 , Figure 9 and Figure 10 As shown: The detection plate 24 is provided with a second limiting groove 243. The length direction of the second limiting groove 243 is parallel to the sliding direction of the detection plate 24. The longitudinal bar of the second U-shaped frame 25 is fixedly provided with a second limiting protrusion 252 that slides with the second limiting groove 243.

[0042] Compared with the prior art, the second limiting groove 243 and the second limiting protrusion 252 of the present invention limit the farthest distance between the second U-shaped frame 25 and the detection plate 24, thereby ensuring that the detection plate 24 will not detach from the second U-shaped frame 25 under the elastic force of the second spring 241.

[0043] See Figures 6-8 As shown: The feeding assembly 2 also includes a movable plate 26, which is set inside the movable frame 22. The movable plate 26 is horizontally set, and a fixed shaft 261 extending downward in the vertical direction is fixedly set on the bottom surface of the movable plate 26. A through hole is opened on the frame 1 to slide with the fixed shaft 261. A third spring 262 is sleeved on the fixed shaft 261. One end of the third spring 262 is fixedly connected to the frame 1, and the other end of the third spring 262 is fixedly connected to the movable plate 26. A third limiting groove 263 is opened on the side of the movable plate 26. The length direction of the third limiting groove 263 is parallel to the transport direction of the feeding belt 3. A third limiting protrusion 221 that slides with the third limiting groove 263 is fixedly set on the movable frame 22. When the movable frame 22 contacts the feeding belt 3, the movable frame 22 moves with the feeding belt 3.

[0044] After the worm shaft is pushed by the push plate 211 and comes into contact with the detector, it will be located on the movable plate 26. The movable plate 26 moves downward in the vertical direction under the gravity of the worm shaft. At this time, the third spring 262 is compressed. The movable frame 22 contacts the feed belt 3 under the push of the movable plate 26. The movable frame 22 will drive the worm shaft to move along the transport direction of the feed belt 3. When the movable frame 22 drives the worm shaft to disengage from the movable plate 26, the worm shaft has rotated 180°. At this time, the bottom of the worm shaft is not in contact with the movable plate 26. The worm shaft falls vertically and lands on the feed belt 3. Compared with the prior art, the movable plate 26 of the present invention allows the worm shaft to automatically fall onto the feed belt 3 after completing the position adjustment, so that the push plate 211 does not need to push it again.

[0045] See Figures 6-8 As shown: A third spring 262 is fixedly installed on the end of the third limiting slide groove 263 away from the push plate 211, and the other end of the third spring 262 is fixedly connected to the third limiting protrusion 221.

[0046] When the movable frame 22 moves the worm shaft, the third spring 262 is compressed. When the worm shaft disengages from the movable plate 26, the second spring 241 is released from compression and pushes the movable plate 26 upward. As the movable plate 26 rises, it moves the movable frame 22 away from the feed belt 3. The third spring 262 is released from compression and pushes the movable frame 22 to its initial position. Compared with the prior art, the third spring 262 of the present invention causes the movable frame 22 to reset, thereby...

[0047] See Figures 5-10 As shown: The top and bottom surfaces of the active frame 22 do not overlap.

[0048] Compared to the prior art, the shape of the movable frame 22 of the present invention is such that the worm shaft detached from the movable plate 26 will not contact the bottom surface of the movable frame 22 when it falls, thereby avoiding direct contact between the worm shaft and the feeding belt 3, and preventing the worm shaft from bouncing and causing it to be in an incorrect position.

[0049] See Figure 6 As shown: Two limiting strips 213 for limiting the position of the worm shaft are fixedly installed on the fixed plate 21. The length direction of the limiting strips 213 is parallel to the transport direction of the feeding belt 3.

[0050] Compared to the prior art, the limiting strip 213 of the present invention limits the position of the worm shaft placed in the fixed plate 21, thereby making the worm shaft contact the detection plate 24 in a fixed state.

[0051] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
