Description

Technical Field

[0001] The present invention relates to the technical field of press equipment, in particular to an angle adjustment device and an adjustment method for an X-shaped guide rail of a press. Background Art

[0002] In precision presses, X-shaped guide rails (with a nearly X-shaped cross-section) are widely used in press motion guidance systems due to their high rigidity and robustness against off-center loads. These guide rails are typically used in conjunction with specialized slides, which are rigidly connected to the press's stamping section via a mechanical interface. This allows the stamping section to achieve high-precision linear motion along the X-shaped guide rail's pre-set trajectory.

[0003] To ensure smooth movement and long life, the clearance between the slider and the guide rail must be strictly controlled within the tolerance range. The existing technology generally uses an adjustable wedge-shaped pressure block (hereinafter referred to as "adjustment block") to achieve gap compensation; However, the above adjustment method has the following significant defects: 1. Complicated operation: Each adjustment requires inserting a feeler gauge between the adjustment block and the guide rail surface, which is extremely difficult to operate in a narrow installation space and is also difficult to pull out; 2. Accuracy depends on manual experience: The feeler gauge withdrawal process may easily cause the adjustment block to rebound slightly, or the fastening bolts need to be loosened before withdrawal, causing the actual gap to deviate from the preset value; 3. Manual adjustment consumes a lot of manpower and time: the fastening bolts of the adjustment block need to be calibrated one by one, which greatly prolongs the equipment debugging cycle. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an angle adjustment device and an adjustment method for an X-shaped guide rail of a press machine, which is free of manual feeler gauges, can quantitatively control the gap and has a gap adjustment function.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: An angle adjustment device for an X-shaped guide rail of a press comprises A servo motor, a sleeve assembly provided on an output shaft of the servo motor, and an adjustment assembly used in conjunction with the sleeve assembly; The adjustment assembly includes a first adjustment rod threadedly engaged with the slider and rotationally engaged with the adjustment block, and a second adjustment rod threadedly engaged with the adjustment block, the first adjustment rod being used to adjust the relative distance between the adjustment block and the X-shaped guide rail, and an adjustment piece being provided at the end of the second adjustment rod for limiting the gap between the adjustment block and the X-shaped guide rail; The sleeve assembly includes a sleeve for driving the first adjusting rod and a sleeve rod for driving the second adjusting rod; The output shaft is provided with a drive sleeve, and a clutch sleeve cooperating with the sleeve and / or sleeve rod is slidably provided inside the drive sleeve. The sleeve assembly drives and adjusts the adjustment assembly through the sliding of the clutch sleeve to achieve the gap positioning between the adjustment block and the X-shaped guide rail.

[0006] In the above solution, preferably, the adjustment piece is symmetrically arranged at the end of the second adjustment rod, and the adjustment block is provided with a limiting groove for accommodating the adjustment piece.

[0007] In the above solution, preferably, one end of the second adjusting rod cooperates with the adjusting block, and the other end is passed through the first adjusting rod and is provided with a hexagonal hole that cooperates with the sleeve rod.

[0008] In the above solution, preferably, one end of the first adjusting rod is rotatably arranged in the adjusting block, and the other end is threaded through the slider and is provided with a hexagonal head that matches the sleeve.

[0009] In the above solution, preferably, the drive sleeve is rotatably engaged with the sleeve, and a concentric rod rotatably engaged with the sleeve rod is provided in the drive sleeve.

[0010] In the above solution, preferably, the inner wall of the clutch sleeve is provided with a first tooth portion and a second tooth portion that cooperate with the sleeve rod, and the outer wall is provided with a third tooth portion that cooperates with the sleeve; The sleeve rod is provided with a fourth tooth portion which can mesh with the first tooth portion or the second tooth portion, and the inner hole of the sleeve is provided with a fifth tooth portion which meshes with the third tooth portion.

[0011] In the above solution, preferably, the clutch sleeve is provided with a plurality of guide plates, and the driving sleeve is provided with guide grooves matching with the guide plates; A shift fork plate is provided after the guide piece passes through the guide groove, and a servo push rod for driving the shift fork plate is provided on the servo motor.

[0012] In the above solution, preferably, the adjustment block is provided with a rotation groove that matches the first adjustment rod, and the end of the first adjustment rod is provided with a rotation plate.

[0013] In the above solution, preferably, the servo motor is provided with a torque sensor, and the servo motor, the torque sensor and the servo push rod are all connected to a PLC controller.

[0014] In the above solution, preferably, the adjustment method of the angle adjustment device of the X-shaped guide rail is as follows: S1: pre-install the adjustment assembly onto the adjustment block and the slider, and then engage the first adjustment rod through the sleeve on the sleeve assembly, and the sleeve rod engages with the second adjustment rod; S2: The servo push rod drives the clutch sleeve to slide, so that the first tooth portion on the clutch sleeve engages with the fourth tooth portion, and then the servo motor drives the drive sleeve to rotate counterclockwise. After the sleeve rod rotates counterclockwise, the second adjustment rod contacts the limit groove wall through the adjustment plate and stops; S3: The servo motor stops after the sleeve rod stops counterclockwise, and then rotates clockwise N circles to make the end face of the adjustment piece and the end face of the adjustment block reach the set gap; S4: The servo push rod drives the clutch sleeve to slide further, so that the first tooth portion and the fourth tooth portion are disengaged. At the same time, the third tooth portion and the fifth tooth portion are engaged, so that the clutch sleeve and the sleeve are matched; S5: The servo motor rotates clockwise, driving the sleeve to rotate, thereby tightening the first adjustment rod relative to the slider. At the same time, the adjustment block moves closer to the surface of the X-shaped guide rail until the end face of the adjustment piece contacts the X-shaped guide rail.

S6: The servo push rod further drives the clutch sleeve to slide, so that the second tooth portion engages with the fourth tooth portion, and at the same time, the third tooth portion engages with the fifth tooth portion, so that the clutch sleeve is synchronously engaged with the sleeve and the sleeve rod; S7: The servo motor rotates counterclockwise, causing the first and second adjustment rods to rotate counterclockwise synchronously.

The servo motor stops via the torque sensor, and the PLC controller records the number of counterclockwise rotations of the servo motor. S8: The servo push rod drives the clutch sleeve to return to the state of step S4. At this time, the servo motor drives the sleeve to rotate clockwise the number of turns recorded in S7, so that the first adjustment rod restores the adjustment block to the gap set in S5. Then, the first adjustment rod is locked to achieve the angle adjustment between one side of the X-shaped guide rail and the adjustment block.

[0015] The beneficial effects of the present invention are as follows: the present invention drives the clutch sleeve to switch three gears through a servo motor, and the linkage sleeve and the sleeve rod control the first and second adjustment rods in a time-sharing manner, thereby realizing fully automatic quantitative adjustment of the gap between the adjustment block and the X-shaped guide rail, and completely eliminating the manual operation of the feeler gauge; At the same time, the mechanical interlocking structure of the adjustment plate and the limit groove, combined with the PLC-controlled torque sensing and angle feedback system, greatly improves the gap control accuracy and eliminates the reliance on manual experience; In addition, a single motor cooperates with the clutch mechanism to complete the entire process of pre-tightening, fine-tuning, and resetting, which greatly shortens the single-side adjustment time and greatly improves the adjustment efficiency. It also realizes mechanized automatic adjustment and has dynamic self-locking capabilities to resist rebound during operation, fundamentally solving the three major technical bottlenecks of efficiency, precision and stability of press guide rail clearance adjustment.

[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Figures 1-6 .

[0023] The angle adjustment device of the X-shaped guide rail of the press machine, the X-shaped guide rail 6 and the slider 4 are slidingly matched, and adjustment blocks 5 that match the X-shaped guide rail 6 are symmetrically provided on both sides of the slider 4. By adjusting the gap between the adjustment blocks 5 on both sides and the surface of the X-shaped guide rail 6, the angle adjustment between the slider 4 and the X-shaped guide rail 6 is achieved, so that the slider 4 slides smoothly and compactly, even if the sliding direction of the entire slider 4 is horizontal with the axis of the X-shaped guide rail 6.

[0024] In this embodiment, the angle adjustment device of the X-shaped guide rail of the press includes a servo motor 1, a sleeve assembly 2 provided on the output shaft 101 of the servo motor 1, and an adjustment assembly 3 used in conjunction with the sleeve assembly 2; The adjusting components 3 are arranged on both sides of the slider 4 and are provided in several groups. The adjusting components 3 also cooperate with the adjusting blocks 5. By adjusting the adjusting components 3, the gap between the slider 4 and the X-shaped guide rail 6 is adjusted.

[0025] like Figure 2 and Figure 6 As shown, the adjustment assembly 3 includes a first adjustment rod 301 that is threadedly engaged with the slider 4 and rotatably engaged with the adjustment block 5. The first adjustment rod 301 is a hollow rod, and a rotating plate 503 is fixed at its end. A rotating groove 502 that is rotatably engaged with the rotating plate 503 is provided in the adjustment block 5. After one end of the first adjustment rod 301 is threaded through the slider 4, the rotating plate 503 at its end is rotatably engaged with the adjustment block 5, and the other end is fixed with a hexagonal head 305. By rotating the hexagonal head 305, the spacing between the adjustment block 5 and the slider 4 can be adjusted. Furthermore, when the X-shaped guide rail 6 is provided in the slider 4, the surface gap between the adjustment block 5 and the X-shaped guide rail 6 can be adjusted by rotating the hexagonal head 305.

[0026] In order to achieve fixed-distance adjustment (i.e., quantitative adjustment) of the gap between the adjustment block 5 and the surface of the X-shaped guide rail 6, a second adjustment rod 302 is passed through the hollow inner hole of the first adjustment rod 301, and the second adjustment rod 302 is threadedly engaged with the adjustment block 5 at one end facing the adjustment block 5, and an adjustment plate 303 is fixed after passing through the adjustment block 5, and the adjustment plates 303 are symmetrically arranged on both sides of the second adjustment rod 302; after the first adjustment rod 301 is passed through the end of the second adjustment rod 302 away from the adjustment block 5, a hexagonal hole 304 is opened at the end, and the hexagonal hole 304 and the hexagonal head 304 are coaxially arranged.

[0027] The adjusting block 5 is provided with a limiting groove 501 for accommodating the adjusting piece 303. Specifically, the limiting groove 501 is an arc groove that cooperates with the adjusting piece 303, that is, the adjusting block 5 is symmetrically provided with an arc groove on one side of the end face of the X-shaped guide rail 6. Figure 5 As shown, a transition slope is set between one end of the arc groove and the end face of the adjustment block 5, and the other end is a straight surface, and the transition slope is set at the end of the second adjustment rod 302 that rotates clockwise, that is, when the second adjustment rod 302 rotates clockwise, the adjustment piece 303 is placed outside the adjustment block 5 after transitioning along the transition slope through its threaded cooperation with the adjustment block 5, so that the end face of the adjustment piece 303 is preferentially in contact with the end face of the X-shaped guide rail 6; when the second adjustment rod 302 rotates counterclockwise, the adjustment piece 303 is hidden in the arc groove, and is limited counterclockwise by the interference between the straight surface and the side wall of the adjustment piece 303.

[0028] The sleeve assembly 2 includes a sleeve 201 for driving a first adjusting rod 301 and a sleeve rod 202 for driving a second adjusting rod 302; specifically, a driving sleeve 102 is provided for sliding cooperation between the spline shaft and the spline hole on the output shaft 101, and an elastic component is provided between the driving sleeve 102 and the servo motor 1, so that the driving sleeve 102 has a certain elastic sliding ability relative to the output shaft 101, and the output shaft 101 can transmit the rotational power to the driving sleeve 102 through the spline cooperation.

[0029] The end of the drive sleeve 102 away from the servo motor 1 extends inward to form a clamping plate, and the outer wall of the sleeve 201 is provided with a clamping groove, which is rotated and clamped with the clamping plate through the clamping groove, that is, the sleeve 201 is rotated and clamped on the drive sleeve 102; the center of the drive sleeve 102 away from the servo motor 1 is provided with a concentric rod 104 that is rotatably clamped with the sleeve rod 202, that is, the sleeve rod 202 is rotatably arranged relative to the drive sleeve 102, and is clamped, such as Figure 3 shown.

[0030] A clutch sleeve 103 is slidably provided in the drive sleeve 102 to cooperate with the sleeve 201 and / or the sleeve rod 202. Specifically, the inner wall of the clutch sleeve 103 is provided with a first tooth portion 11 and a second tooth portion 12 that cooperate with the sleeve rod 202. The inner hole wall of the clutch sleeve 103 can be slidably sleeved on the sleeve rod 202. The outer wall of the sleeve rod 202 facing the clutch sleeve 103 is provided with a fourth tooth portion 14. A gap is provided between the first tooth portion 11 and the second tooth portion 12. When the clutch sleeve 103 slides toward the fourth tooth portion 14 (recorded as the first position), through the fourth tooth portion 14 The first tooth portion 11 meshes with the fourth tooth portion 14 and then slides further (referred to as the second position) so that the fourth tooth portion 14 is located in the gap between the first tooth portion 11 and the second tooth portion 12. At this time, the fourth tooth portion 14 is disengaged from the clutch sleeve 103. When the clutch sleeve 103 rotates, the sleeve rod 202 does not rotate accordingly. After the clutch sleeve 103 further slides toward the fourth tooth portion 14 (referred to as the third position), the second tooth portion 12 meshes with the fourth tooth portion 14. At this time, the clutch sleeve 103 re-engages with the sleeve rod 202, completing power transmission.

[0031] The outer wall of the clutch sleeve 103 is provided with a third tooth portion 13 that matches the inner wall of the sleeve 201; the inner hole of the sleeve 201 is provided with a fifth tooth portion 15 that meshes with the third tooth portion 13. When the clutch sleeve 103 slides and is in the first position, that is, Figure 3 As shown, at this time, the third tooth portion 13 is not in contact with the fifth tooth portion 15. When the clutch sleeve 103 slides to the second position and the third position, the clutch sleeve 103 is engaged with the fifth tooth portion 15 through the third tooth portion 13, so that the power of the clutch sleeve 103 is transmitted to the sleeve 201.

[0032] In summary, the sliding of the clutch sleeve 103 realizes the driving adjustment of the sleeve assembly 2 on the adjustment assembly 3, that is, the rotation of different adjustment rods in the adjustment assembly 3 is driven to achieve the gap positioning between the adjustment block 5 and the X-shaped guide rail 6.

[0033] In order to realize the sliding of the clutch sleeve 103, a plurality of guide plates 21 are provided on the clutch sleeve 103, and a guide groove 22 matching the guide plate 21 is provided on the end wall of the drive sleeve 102 close to the servo motor 1. The clutch sleeve 103 slides through the drive sleeve 102 through the guide plates 21; after the guide plates 21 pass through the guide grooves 22, a rotating sleeve is provided with a shift fork plate 23, and the servo motor 1 is provided with a servo push rod 24 for driving the shift fork plate 23, and the servo push rod 24 is used to realize the switching of the clutch sleeve 103 between the above-mentioned first position, second position and third position; the servo motor 1 is provided with a torque sensor, and the servo motor 1, the torque sensor and the servo push rod 24 are all connected to the PLC controller.

[0034] In order to ensure that the second adjusting rod 302 and the first adjusting rod 301 are relatively fixed after the adjustment component 3 is adjusted, so that the first adjusting rod 301 is fixed relative to the slider 4 through the limitation of the adjustment piece 303 in the limiting groove 501, in this embodiment, a melting cavity 31 is provided in the hexagonal head 305, and a tin alloy or lead alloy is provided in the melting cavity 31. The outer wall of the end of the second adjusting rod 302 is placed in the melting cavity 31. Initially, the alloy in the melting cavity 31 is solid, and a hole for the second adjusting rod 302 to pass through is provided in the center. When the alloy in the melting cavity 31 is melted, the hexagonal head 305 can be fixed to the second adjusting rod 302 through the molten tin alloy or lead alloy.

[0035] The hexagonal head 305 is provided with a heat-conducting rod 32 that is connected to the melting chamber 31. The heat-conducting rod 32 is provided on any one surface of the hexagonal head 305. The inner hole wall of the sleeve 201 is surrounded by an electric heating ring 33. When the sleeve 201 is sleeved on the hexagonal head 305, the heat-conducting rod 32 is heated by the electric heating ring 33 to generate a high temperature, further melting the tin alloy or lead alloy in the melting chamber 31, thereby achieving fusion welding and fixation between the first adjustment rod 301 and the second adjustment rod 302.

[0036] The tin alloy or lead alloy is a low melting point alloy, that is, it can be melted into liquid state when the heat conducting rod 32 is in a red-molten state. It can also be replaced by pure tin or pure lead according to actual working conditions.

[0037] The electric heating ring 33 is controlled by a PLC controller to achieve real-time heating and precise control, and its temperature range can be specifically set, that is, adjusted and selected according to the different materials of the molten weld in the melting chamber 31.

[0038] The adjustment method of the angle adjustment device using the X-shaped guide rail is as follows: S1: Pre-install the adjustment assembly 3 onto the adjustment block 5 and the slider 4. Then, the sleeve 201 on the sleeve assembly 2 is engaged with the first adjustment rod 301, and the sleeve rod 202 is engaged with the second adjustment rod 302. S2: The servo push rod 24 drives the clutch sleeve 103 to slide, so that the first tooth portion 11 on the clutch sleeve 103 engages with the fourth tooth portion 14. Then, the servo motor 1 drives the drive sleeve 102 to rotate counterclockwise. After the sleeve rod 202 rotates counterclockwise, the second adjustment rod 302 stops after the adjustment piece 303 contacts the wall of the limiting groove 501. S3: The servo motor 1 stops after the sleeve rod 202 stops counterclockwise, and then rotates clockwise N times to make the end surface of the adjustment piece 303 and the end surface of the adjustment block 5 reach the set gap; S4: The servo push rod 24 drives the clutch sleeve 103 to slide further, so that the first tooth portion 11 and the fourth tooth portion 14 are disengaged. At the same time, the third tooth portion 13 and the fifth tooth portion 15 are engaged, so that the clutch sleeve 103 is matched with the sleeve 201. S5: The servo motor 1 rotates clockwise, driving the sleeve 201 to rotate, thereby tightening the first adjustment rod 301 relative to the slider 4. At the same time, the adjustment block 5 approaches the surface of the X-shaped guide rail 6 until the end surface of the adjustment piece 303 contacts the X-shaped guide rail 6. The servo motor 1 is stopped by the torque sensor. At this time, the gap between the adjustment block 5 and the X-shaped guide rail 6 reaches the set gap. S6: The servo push rod 24 further drives the clutch sleeve 103 to slide, so that the second tooth portion 12 is engaged with the fourth tooth portion 14. At the same time, the third tooth portion 13 is engaged with the fifth tooth portion 15, so that the clutch sleeve 103 is synchronously engaged with the sleeve 201 and the sleeve rod 202. S7: The servo motor 1 rotates counterclockwise, causing the first adjustment rod 301 and the second adjustment rod 302 to rotate counterclockwise synchronously. The second adjustment rod 302 stops after the adjustment piece 303 contacts the wall of the limiting groove 501. The servo motor 1 stops via the torque sensor, and the PLC controller records the number of counterclockwise rotations of the servo motor 1. S8: The servo push rod 24 drives the clutch sleeve 103 to return to the state of step S4. At this time, the servo motor 1 drives the sleeve 201 to rotate clockwise for the number of turns recorded in S7, so that the first adjustment rod 301 restores the adjustment block 5 to the gap set in S5. Then, the first adjustment rod 301 is locked to achieve the angle adjustment between one side of the X-shaped guide rail 6 and the adjustment block 5.
