Description

Technical Field

[0001] This utility model belongs to the field of machining, and in particular relates to a diamond dressing roller with an adjustment mechanism. Background Technology

[0002] Diamond dressing rollers use diamond particles as abrasives to dress the surface of a grinding wheel, replicating their own profile precision onto the wheel, which then grinds the workpiece. Their core function is to ensure the shape accuracy and cutting performance of the grinding wheel, making them suitable for dressing high-hardness materials such as ceramic and CBN grinding wheels. The roller is mounted on the dressing device of a grinding machine and rotates at high speed to contact the grinding wheel surface, removing the passivation layer or adjusting its geometry to restore the wheel's sharpness and precise profile. However, some diamond rollers in related technologies cannot precisely control the contact pressure between the roller and the grinding wheel, leading to increased deviations in the grinding wheel's profile and preventing accurate replication to the workpiece surface. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A diamond dressing roller with an adjustment mechanism includes a drive motor, a roller body, a first fixed seat, a second fixed seat, two first connecting structures, two second connecting structures, and two spring-loaded adjustment mechanisms.

[0006] The roller body is connected to the output end of the drive motor via a mounting structure;

[0007] The first fixing seat and the second fixing seat are symmetrically arranged on the front and rear sides of the drive motor. The inner end face of the first fixing seat and the second fixing seat is provided with an arc-shaped groove that can cooperate with the drive motor housing. The first fixing seat and the second fixing seat are connected by multiple bolts.

[0008] A first fixing plate is provided on both the left and right sides of the first fixing base, and the first fixing plate is integrally connected to the first fixing base. A second fixing plate is provided on both the left and right sides of the second fixing base, and the second fixing plate is integrally connected to the second fixing base.

[0009] Two spring-loaded adjustment mechanisms are symmetrically arranged on the left and right. The spring-loaded adjustment mechanisms pass through the first fixed plate and the second fixed plate located on the same side. The front and rear ends of the spring-loaded adjustment mechanisms are respectively provided with a first connecting structure and a second connecting structure.

[0010] Furthermore, the spring-loaded adjustment mechanism includes a slide rod, a first clamping nut, and two first clamping assemblies. The slide rod passes through a first fixing plate and a second fixing plate located on the same side. The two first clamping assemblies are symmetrically arranged on the slide rod. The first fixing plate and the second fixing plate are located between the two first clamping assemblies. The first clamping nut clamps the first clamping assembly located at the outer end of the slide rod. The first connecting structure and the second connecting structure are symmetrically arranged at the front and rear ends of the slide rod.

[0011] Furthermore, the first clamping assembly includes a fixed sleeve, a clamping spring, a buffer rubber sleeve, and two pressure plates. The fixed sleeve, clamping spring, buffer rubber sleeve, and two pressure plates are all sleeved on the slide rod. The front and rear end faces of the fixed sleeve are provided with annular grooves. The clamping spring and the buffer rubber sleeve are symmetrically arranged on both sides of the fixed sleeve. A pressure plate is correspondingly arranged on the outer side of the clamping spring and the buffer rubber sleeve. The clamping spring and the buffer rubber sleeve cooperate with the fixed sleeve through the annular grooves.

[0012] Furthermore, the second connection structure includes a mounting plate and two connecting bolts. The mounting plate is connected to the end of the slide rod via a hinge structure, and the two connecting bolts are symmetrically arranged on the mounting plate. The first connection structure is the same as the second connection structure.

[0013] Furthermore, the first fixing plate is provided with two first reinforcing ribs at the connection position between the first fixing plate and the first fixing seat, and the second fixing plate is provided with a second reinforcing rib at the connection position between the second fixing plate and the second fixing seat.

[0014] Furthermore, it also includes a second clamping assembly and a second clamping nut. The second clamping assembly is disposed between the two first fixing plates and the second fixing plate. The second clamping nut is threadedly connected to the slide rod. The second clamping nut is used to clamp the second clamping assembly. The second clamping assembly has the same structure as the first clamping assembly.

[0015] Compared with the prior art, the diamond dressing roller with an adjustment mechanism described in this utility model has the following advantages:

[0016] 1. The diamond dressing roller solves the problem of grinding wheel profile deviation caused by inaccurate contact pressure control in traditional technologies by employing two symmetrically arranged spring-loaded adjustment mechanisms. Its design significantly improves dressing accuracy and stability through the synergistic effect of elastic pressure compensation, dynamic vibration reduction, and symmetrical rigid support. The two spring-loaded adjustment mechanisms are symmetrically arranged, and pressure is applied synchronously by the first clamping components on both sides of the slide bar, eliminating localized over-cutting or under-cutting of the grinding wheel caused by unilateral unbalanced loading.

[0017] 2. The compression of the clamping spring is adjusted via the first clamping nut to achieve precise setting of the contact pressure. As the grinding wheel wears and its diameter decreases, the spring automatically compensates for the displacement through elastic deformation, maintaining constant pressure and preventing the accumulation of contour deviations. The buffer rubber sleeve and the clamping spring form a high-frequency-low-frequency composite damping, converting the impact energy from hard points on the grinding wheel surface or the vibration energy from the spindle into heat dissipation, reducing the vibration amplitude by 40%–60% and protecting diamond particles from abnormal shedding. The annular groove design of the fixing sleeve constrains the axial displacement of the spring and the rubber sleeve, preventing the components from loosening under high-frequency vibration and ensuring a stable pressure transmission path.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] A diamond dressing roller with an adjustment mechanism, such as Figure 1 As shown, it includes a drive motor 200, a roller body 100, a first fixed base 310, a second fixed base 320, two first connecting structures 500, two second connecting structures 700, and two spring-loaded adjustment mechanisms; the roller body 100 is connected to the output end of the drive motor 200 through the mounting structure 110.

[0030] The first fixing seat 310 and the second fixing seat 320 are symmetrically arranged on the front and rear sides of the drive motor 200. The inner end face of the first fixing seat 310 and the second fixing seat 320 is provided with an arc-shaped groove that can cooperate with the housing of the drive motor 200. The first fixing seat 310 and the second fixing seat 320 are connected by multiple bolts.

[0031] A first fixing plate is provided on both the left and right sides of the first fixing base 310, and the first fixing plate is integrally connected to the first fixing base 310. A second fixing plate is provided on both the left and right sides of the second fixing base 320, and the second fixing plate is integrally connected to the second fixing base 320. The second connecting structure 700 includes a mounting plate 610 and two connecting bolts 620. The mounting plate 610 is connected to the end of the slide rod through a hinge structure 630. The two connecting bolts 620 are symmetrically arranged on the mounting plate 610. The first connecting structure 500 and the second connecting structure 700 are the same. Two first reinforcing ribs are provided at the connection position between the first fixing plate and the first fixing base 310, and two reinforcing ribs are provided at the connection position between the second fixing plate and the second fixing base 320.

[0032] like Figure 2 As shown, two spring-loaded adjustment mechanisms are symmetrically arranged on the left and right sides. Each spring-loaded adjustment mechanism passes through a first fixed plate and a second fixed plate located on the same side. A first connecting structure 500 and a second connecting structure 700 are respectively provided at the front and rear ends of the spring-loaded adjustment mechanism. The diamond dressing roller, through the two symmetrically arranged spring-loaded adjustment mechanisms, solves the problem of grinding wheel profile deviation caused by inaccurate contact pressure control in traditional technologies. Its design significantly improves dressing accuracy and stability through the synergistic effect of elastic pressure compensation, dynamic vibration reduction, and symmetrical rigid support. The symmetrical layout of the two spring-loaded adjustment mechanisms, through the simultaneous application of pressure by the first clamping components 410 on both sides of the slide bar, eliminates local over-cutting or under-cutting of the grinding wheel caused by unilateral uneven loading.

[0033] The spring-loaded adjustment mechanism includes a slide rod, a first clamping nut, and two first clamping assemblies 410. The slide rod passes through a first fixing plate and a second fixing plate located on the same side. The two first clamping assemblies 410 are symmetrically arranged on the slide rod. The first fixing plate and the second fixing plate are located between the two first clamping assemblies 410. The first clamping nut clamps the first clamping assembly 410 located at the outer end of the slide rod. The first connecting structure 500 and the second connecting structure 700 are symmetrically arranged at the front and rear ends of the slide rod.

[0034] like Figure 3As shown, the first clamping assembly 410 includes a fixed sleeve 401, a clamping spring, a buffer rubber sleeve 403, and two pressure plates 402. The fixed sleeve 401, clamping spring, buffer rubber sleeve 403, and two pressure plates 402 are all sleeved on the slide rod. The front and rear end faces of the fixed sleeve 401 are provided with annular grooves. The clamping spring and buffer rubber sleeve 403 are symmetrically arranged on both sides of the fixed sleeve 401. A pressure plate 402 is correspondingly arranged on the outer side of each clamping spring and buffer rubber sleeve 403. The clamping spring and buffer rubber sleeve 403 cooperate with the fixed sleeve 401 through the annular grooves. It also includes a second clamping assembly 400 and a second clamping nut 600. The second clamping assembly 400 is disposed between the two first fixed plates and the second fixed plate. The second clamping nut 600 is threadedly connected to the slide rod and is used to clamp the second clamping assembly 400. The second clamping assembly 400 has the same structure as the first clamping assembly 410. The compression of the clamping spring is adjusted via the first clamping nut to achieve precise setting of the contact pressure. As the grinding wheel wears and its diameter decreases, the spring automatically compensates for the displacement through elastic deformation, maintaining constant pressure and preventing the accumulation of contour deviations. The buffer rubber sleeve 403 and the clamping spring form a high-frequency-low-frequency composite damping, converting the impact energy from hard points on the grinding wheel surface or the vibration energy from the spindle into heat dissipation, effectively reducing the vibration amplitude and protecting diamond particles from abnormal shedding. The annular groove design of the fixing sleeve 401 constrains the axial displacement of the spring and the rubber sleeve, preventing the components from loosening under high-frequency vibration and ensuring a stable pressure transmission path.

[0035] How this example works

[0036] Step 1: Connect the diamond roller body 100 to the output end of the drive motor 200 through the mounting structure 110, ensuring that the axial concentricity error is ≤0.01mm.

[0037] The first fixing seat 310 and the second fixing seat 320 are symmetrically clamped on both sides of the drive motor 200 housing, fit the motor housing through the arc groove, and are fastened with multiple bolts.

[0038] The mounting plate 610 of the first connecting structure 500 is connected to the front end of the slide rod through the hinge structure 630. The angle of the mounting plate 610 is adjusted (e.g., within ±5° range) to align it with the grinding machine fixed base.

[0039] The mounting plate 610 is fixed to the grinding machine base using two symmetrical connecting bolts 620, with a torque of 20 to 30 N·m (depending on the bolt specifications) applied to ensure rigid support.

[0040] Step 2: The mounting plate 610 of the second connecting structure 700 is also connected to the rear end of the slide rod through the hinge structure 630 to fix the cooling nozzle or sensor module (such as an acoustic emission monitoring device).

[0041] Loosen the connecting bolts 620, adjust the pitch angle of the mounting plate 610 through the hinge structure 630, align the nozzle with the roller-grinding wheel contact area, and then tighten the bolts.

[0042] Rotate the first and second clamping nuts 600 to compress the clamping spring to the set preload (for CBN grinding wheels, the spring length needs to be compressed to 80% of the initial length).

[0043] Check the fit between the buffer rubber sleeve 403 and the pressure plate 402 to ensure there is no gap (this can be checked with a feeler gauge; the gap should be ≤0.02mm).

[0044] Step 3: Start the drive motor 200 and drive the roller to contact the grinding wheel surface with a speed ratio of qd = +0.5. Fine-tune the roller cutting angle through the mounting plate 610 of the first connecting structure 500.

[0045] The roller rapidly approaches the grinding wheel at a speed of 50 mm / min, and the contact signal is monitored by a sensor connected to the second connection structure 700.

[0046] The cutting speed is reduced to 5mm / min, the total trimming amount is 0.03mm, and the finishing time is 3-5 seconds (set via PLC program).

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
