Description

Technical Field

[0001] This utility model relates to adjustment components, and more particularly to a component for adjusting a multi-point grinding wheel. Background Technology

[0002] In the fields of food processing and grinding mills, the axial adjustment accuracy and stability of the grinding wheel assembly directly affect the equipment's working efficiency and the service life of its core components. Traditional grinding wheel adjustment mechanisms often employ a design combining a threaded drive with a manual adjustment handwheel. Rotating the handwheel drives the screw to move axially, thereby changing the position of the grinding wheel holder. However, this design has the following significant drawbacks:

[0003] Insufficient anti-loosening performance: Traditional handwheels rely on the friction of the threaded pair to maintain their position. During long-term operation, they are prone to rotational deviation due to vibration or load, requiring frequent correction and affecting the parallelism of the grinding wheel and the grinding effect. For example, although CN213557386U, a slurry separator with a shaft drive and integrated crusher, mentions adjusting the handwheel, it lacks an active anti-loosening mechanism, thus limiting its stability.

[0004] Poor operational flexibility: The handwheel has high rotational resistance, especially under high load conditions. The adjustment process requires a large operating force and lacks a buffer structure. It is easy for the installation error of the rigid transmission chain or thermal deformation to aggravate the floating of the grinding wheel and accelerate wear.

[0005] To address the aforementioned issues, there is an urgent need for a new type of multi-point adjustable grinding wheel assembly that can achieve high precision and multi-level adjustment while also possessing features such as anti-loosening self-locking, elastic buffering, and easy operation, thereby improving the working life of the grinding wheel and the overall reliability of the equipment. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a component for adjusting a grinding wheel at multiple points.

[0007] To solve the above technical problems, the technical solution adopted by this utility model is: a component for a multi-point adjustable grinding wheel, comprising:

[0008] The integrated unit includes a coaxially movably fitted grinding wheel seat and a cylinder head. The cylinder head has three steps that gradually narrow from bottom to top. The lower step connects to the cylinder block, and the middle step has multiple guide pillar seats.

[0009] The guide post unit has multiple guide posts evenly distributed around the horizontal end plate of the grinding wheel seat. Each guide post is inserted into the guide post seat in a corresponding manner. Each guide post is fitted with a guide post spring. The lower end of the guide post spring abuts against the grinding wheel seat, and the upper end abuts against the end face of the guide post seat.

[0010] The adjustment unit includes a handwheel, which is connected to a lifting screw via a threaded connection. A handwheel washer is installed on the positioning shaft seat of the cylinder head. A handwheel anti-reverse spring is sleeved around the lifting screw, and the handwheel anti-reverse spring is pre-compressed between the handwheel washer and the step of the positioning shaft seat. The lifting screw is connected to a grinding wheel seat.

[0011] Furthermore, the coaxially fitted grinding wheel holder and cylinder head are specifically connected through the feed channel of the coaxially fitted grinding wheel holder within the hollow channel of the cylinder head, forming a material conveying path.

[0012] Furthermore, the middle step is provided with three or four guide post seats, and the horizontal end plate of the grinding wheel seat is evenly distributed with multiple guide posts corresponding to the number of guide post seats.

[0013] Furthermore, the lower step of the cylinder head is connected to the cylinder block through a stop fit.

[0014] Furthermore, the handwheel has an internal thread, and the lifting screw has an external thread that matches the internal thread.

[0015] Furthermore, the upper end of the handwheel anti-reverse spring abuts against the end of the handwheel washer, and the lower end of the handwheel anti-reverse spring abuts against the stepped end face of the positioning shaft seat.

[0016] Furthermore, the handwheel washer is installed at the upper opening of the positioning shaft seat of the cylinder head, and the handwheel washer abuts against the lower end face of the handwheel.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] The present invention discloses a multi-point adjustable grinding wheel assembly, including an integrated unit for structural support and functional integration, a guide post unit for axial movement guidance and elastic buffering, and a manual adjustment and anti-loosening control adjustment unit.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the integrated unit includes a coaxially movably fitted grinding wheel holder 1 and a cylinder head 4. The cylinder head 4 has three steps that gradually narrow from bottom to top: an upper step 4a, a middle step 4b, and a lower step 4c. The centers of the upper, middle, and lower steps together form a hollow channel 2. The feed channel 3 of the grinding wheel holder 1 is coaxially fitted within the hollow channel 2 of the cylinder head 4. An upper grinding wheel 6 is connected to the grinding wheel holder 1. The hollow channel 2 and the feed channel 3 are connected to form a material conveying path. The lower step 4c is connected to the cylinder body through a stop fit. The feed channel 3 is axially movably positioned within the central hole of the upper step 4a of the cylinder head 4.

[0028] like Figure 3 and Figure 4 The guide post unit shown includes four guide posts 5 evenly distributed circumferentially on the horizontal end plate of the grinding wheel holder 1, and four guide post seats 7 on the middle step 4b of the cylinder head 4 for precise guidance of the guide post unit. Each guide post 5 is inserted into a corresponding guide post seat 7. The precise fit between the guide post 5 and the guide post seat 7 ensures the coaxial accuracy of the grinding wheel holder 1's axial movement, preventing offset or tilting. Each guide post 5 is fitted with a guide post spring 8, with the lower end of the spring abutting against the grinding wheel holder 1 and the upper end abutting against the end face of the guide post seat 7. In other embodiments, three guide posts 5 are evenly distributed circumferentially on the horizontal end plate of the grinding wheel holder 1, each inserted into a corresponding guide post seat 7. The guide post spring 8 provides elastic restoring force under compression, which both buffers vibration during grinding wheel holder movement and maintains stable contact pressure between the grinding wheel and the workpiece. It should be noted that the multiple guide posts are arranged symmetrically, and the even distribution of guide posts balances the force, further improving the smoothness of the grinding wheel holder's movement.

[0029] like Figure 4-6The adjustment unit shown includes a handwheel 9, which is connected to a lifting screw 10 via a threaded pair. The handwheel 9 has an internal thread, and the lifting screw 10 has an external thread that matches the internal thread. The handwheel 9 drives the lifting screw 10 to move axially via the threaded pair. The lifting screw 10 is connected to a grinding wheel seat 1 via a connecting shaft 14, which drives the grinding wheel seat 1 to adjust its position along the guide post 5. In this embodiment, there are two sets of handwheels 9 and lifting screws 10, which are symmetrically distributed to form two axial adjustment positions. Reducing the adjustment coverage point of a single axial adjustment position achieves the effect of reducing the adjustment torque per unit area.

[0030] A handwheel washer 11 is installed on the positioning shaft seat 12 of the cylinder head 4. The handwheel washer 11 is installed at the upper opening of the positioning shaft seat 12 of the cylinder head, and abuts against the lower end face of the handwheel 9. A handwheel anti-reverse spring 13 is sleeved around the lifting screw 10. The upper end of the handwheel anti-reverse spring 13 abuts against the positioning structure of the handwheel washer, such as a boss or a groove, and the lower end of the handwheel anti-reverse spring 13 abuts against the stepped end face of the positioning shaft seat 12. During assembly, the handwheel anti-reverse spring is compressed between the washer and the positioning shaft seat, generating continuous axial pressure. The handwheel washer 11 is always tightly pressed against the lower end face of the handwheel 9 by the spring force. The handwheel anti-reverse spring increases the frictional resistance of the threaded pair by increasing the pressure on the handwheel washer, resisting the tendency of the handwheel to rotate. This connection method establishes a stable axial load in the threaded transmission chain through the compression energy storage characteristics of the spring, which not only achieves the anti-loosening function, but also does not affect the flexibility of manual adjustment.

[0031] In use, the operator turns the handwheel, converting the rotational motion into linear motion of the lifting screw via the threaded pair (internal thread of the handwheel and external thread of the lifting screw). The lifting screw, through the screw positioning shaft, drives the grinding wheel holder to adjust its position axially. The grinding wheel holder moves axially along four circumferentially distributed guide posts; the guide post springs provide elastic support under compression, maintaining the smoothness of axial movement while also having a tendency to return to its original position. The handwheel anti-loosening spring increases the frictional resistance of the threaded pair by continuously applying axial pressure, achieving an anti-loosening function while allowing for fine adjustments. The symmetrical layout of the four guide posts ensures the coaxial accuracy of the grinding wheel holder's axial movement, and together with the precision transmission of the threaded pair, ultimately achieving precise multi-point adjustment of the grinding wheel's position.

[0032] In summary, this patent has the following core advantages and innovative benefits:

[0033] High precision and stability: The symmetrical guide post layout guide post unit adopts multiple guide posts evenly distributed around the circumference, and with the guide post springs (right) to provide elastic support, ensure the coaxial accuracy of the axial movement of the grinding wheel seat, avoid offset or tilting, and improve the uniformity of contact between the grinding wheel and the workpiece.

[0034] Precision transmission design: The handwheel drives the lifting screw through a threaded pair, and combined with the precision guidance of the guide column, it can achieve precise fine adjustment of the grinding wheel position to meet the needs of high-precision machining.

[0035] Optimized anti-loosening and self-locking performance: The pre-compressed handwheel anti-locking spring continuously applies axial pressure, increasing the frictional resistance of the threaded pair, effectively resisting the handwheel's self-rotation offset caused by vibration or load, significantly improving positional stability, and reducing the frequency of manual correction.

[0036] Easy operation and vibration damping: The guide spring provides elastic restoring force under compression, which can both buffer the impact vibration when the grinding wheel seat moves and maintain a constant contact pressure between the grinding wheel and the workpiece, reducing wear caused by rigid transmission. Two sets of symmetrically distributed handwheels and lifting screws (specific implementation) distribute the adjustment torque, reduce single-point operating resistance, and make adjustment under high load conditions more effortless.

[0037] Wide range of applications: Suitable for food processing, grinding machines, precision grinding and other fields, especially suitable for industrial scenarios with high requirements for adjustment accuracy, anti-loosening performance and ease of operation.
