Description

Technical Field

[0001] The present application relates to the field of grinding machines, and in particular to a ball grinding machine. Background Art

[0002] A ball valve is a commonly used valve that controls the flow of fluid by rotating. The rotating part of the ball valve is a sphere. In order to reduce rotational friction, the surface of the sphere needs to be polished smooth.

[0003] When grinding the sphere, a set of limiting mechanisms is required to position the sphere. The limiting mechanism usually includes a bracket connecting part located on one side of the sphere. The bracket connecting part passes through the sphere and then fixes the sphere by an internal expansion clamp. The sphere is stabilized by the bracket connecting part. A push rod component is provided on the other side to cooperate with the bracket connecting part to stabilize the sphere. The position of the sphere is fixed by the bracket connecting part and the push rod component and then rotated to grind the outer surface of the sphere in cooperation with the grinding disc.

[0004] The push rod component usually uses a cylinder to realize the movement of the push rod. The movement of the push rod cooperates with the bracket connection part to stabilize the sphere. However, the length of the cylinder is relatively long, and the length of the cylinder is usually greater than the maximum stroke that the telescopic rod can extend, resulting in the overall length of the equipment being too long. Summary of the invention

[0005] In order to improve the problem of the equipment being too long, the present application provides a ball grinder.

[0006] The present application provides a ball grinding machine, which adopts the following technical solution:

[0007] A ball grinding machine comprises a base, on which a bracket connecting component and a push rod component are arranged, the bracket connecting component comprises a through rod for passing through a sphere, the through rod is provided with an internal expansion component, the internal expansion component is used to press against the inner wall of the sphere for fixing, the push rod component comprises a screw driving component arranged on the base and a push rod assembly slidably arranged on the base for pressing against the through rod, a screw is arranged on the rotating shaft of the screw driving component, and the screw is threadedly connected to the push rod assembly.

[0008] By adopting the above technical solution, the original oil cylinder is replaced by a screw rod and a screw rod driving member, thereby shortening the length by half and greatly reducing the overall length of the equipment.

[0009] Optionally, the push rod component includes a base slidably arranged on the base, the base is threadedly connected to the screw rod, a top seat is slidably arranged on the base, a movable driving member for driving the top seat to slide is arranged on the base, and the push rod assembly is arranged on the top seat.

[0010] By adopting the above technical solution, double-layer segmented propulsion is achieved through isomorphic moving drive components and screw drive components, so that it can adapt to more spheres of different sizes, reduce the probability that the base collides with the sphere before the push rod assembly due to the sphere being too large, or the push rod assembly extends too far outside the top seat of the base, causing center instability, thereby improving adaptability and stability.

[0011] Optionally, the push rod assembly includes a bearing member rotatably arranged on the top seat, the bearing member is provided with a top ring for pushing the through rod, the through rod is provided with a clamping rod for inserting into the top ring, the clamping rod is telescopically and slidably provided with a plurality of clamping blocks, the inner wall of the top ring is provided with a plurality of clamping grooves for inserting the clamping blocks, the clamping blocks are inserted into the clamping grooves to limit the sliding and rotation of the through rod, and a plurality of reset members are provided in the through rod, and the reset members are used to pull the clamping blocks toward the through rod.

[0012] By adopting the above technical scheme, the height position of the through rod is fixed by the top ring and the end of the through rod being pressed tightly, so that the through rod is kept at this height position to drive the ball to rotate and grind. At this time, the clamping rod is directly inserted into the top ring, and the clamping block is not aligned with the clamping groove. Under the rotation of the through rod, the clamping block is thrown out under the action of centrifugal force and hits the inner wall of the top ring, further increasing the friction between the top ring and the through rod. If the friction between the through rod and the top ring is reduced due to long-term use without maintenance, resulting in slippage and instability, the clamping block will be displaced in the top ring until the clamping block is aligned with the clamping groove. The clamping block will be inserted into the clamping groove under the action of centrifugal force, making it difficult for the through rod to continue to slide, thereby realizing further position limitation of automatic triggering, which is convenient, fast and effective, with a simple and reliable structure. When the speed is reduced, the clamping block is pulled back into the clamping rod by the reset member to achieve reset, and the clamping between the contact top ring and the clamping rod is achieved to achieve automatic reset, which is convenient and fast.

[0013] Optionally, the bracket connecting component includes a speed detection component, which is used to detect the speed of the penetration rod to obtain active speed data; a pressure detection component is provided on the inner wall of the clamping groove, and the pressure detection component is used to detect whether the clamping block is tightly against the bottom wall of the clamping groove to obtain insertion pressure data; and a data processing module is included to receive the active speed data and the insertion pressure data and perform data processing to obtain a processing signal and output it.

[0014] By adopting the above technical solution, the influence of slippage is automatically determined and calculated by detecting the rotation speed and pressure, and then correction is achieved by controlling the driving source of the piercing rod, which is convenient and fast, improves product quality, and reduces the influence of uneven grinding caused by slippage.

[0015] The present application provides a grinding correction method, which adopts the following technical solution:

[0023] The fluctuation position correction speed data is determined and outputted through the fluctuation position interval, the speed difference data and the temporarily stored data, and the processed signal includes the fluctuation position correction speed data.

[0024] By adopting the above technical solution, the data required for correction is automatically calculated and output for control, and the user is reminded at the same time, which is convenient and fast, improves processing efficiency and improves product quality.

[0030] Optional, including:

[0031] Determine expired data by using the misalignment judgment data, the time data, and a preset time interval threshold;

[0032] New temporarily stored data are determined by using the expired data and the original temporarily stored data, and the new temporarily stored data replace the original temporarily stored data to participate in the calculation of the processing signal.

[0033] By adopting the above technical solution, since high-frequency storage data occupies a large storage space, expired and useless temporary storage data is automatically deleted to save storage space.

With the development of integrated circuit technology, some protocols that belong to the external bus (E-Bus) protocol are also classified as internal protocols after the external bus (E-Bus) is integrated into the chip.

[0058] Embodiment 2 of the present application discloses a grinding correction method. Figure 6 , the grinding correction method comprises the following steps:

[0059] S1, obtain active speed data, obtain insertion pressure data, and obtain time data;

[0060] S11, determining temporary storage data through active speed data, time data, and a preset high-frequency detection threshold;

[0061] S12, determining misalignment judgment data through insertion pressure data, active speed data, a preset insertion pressure threshold, and time data;

[0062] S13, determining the fluctuation speed data by temporarily storing the data and the misalignment judgment data;

[0063] S14, determining speed difference data through the fluctuating speed data and the temporarily stored data;

[0064] S15, determining the fluctuation position interval through the speed difference data, the fluctuation speed data, and the temporarily stored data;

[0065] S16. Determine and output the fluctuation position corrected speed data through the fluctuation position interval, the speed difference data, and the temporarily stored data. The processed signal includes the fluctuation position corrected speed data.

[0066] In detail: the high-frequency detection threshold is the frequency of recording active speed data. If the high-frequency detection threshold is [50hz,5s], it means that the active speed data is recorded 50 times per second on average, that is, once every 0.02 seconds, and the total recording time is 5s. The recording time is recorded according to the time data, and the active speed data within 5 consecutive seconds is recorded, and a total of 250 active speed data form temporary storage data; the insertion pressure threshold is a coefficient related to the active speed data. If the insertion pressure threshold is x, if the active speed data is y, if the insertion pressure data is 1200N, if 1200>x*y, it is judged that the clamping block 14 is inserted into the clamping groove 33, and the output indicates that the relative rotation of the top ring 32 and the through rod 11 has occurred. Dislocation judgment data, and if the insertion pressure data is less than x*y, that is, less than 100 0N, output the misalignment judgment data of non-insertion, that is, the top ring 32 and the penetration rod 11 have not rotated relative to each other. This pressure may be caused by the centrifugal force generated by the rotation. The higher the rotation speed, the larger the y in the calculated x*y, the greater the centrifugal force, and the larger the threshold used for comparison with the insertion pressure data to eliminate the interference of the centrifugal force; if the misalignment judgment data is relative rotation, the time when the relative rotation occurs is judged according to the time data. If the time data when the insertion pressure data exceeds x*y is 3.02s, the active speed data corresponding to the time data near 3.02s in the temporary storage data is read. If the active speed data drops from 1r / s to 0.8r / s within the time data of 0.5s as early as then, and then rises from 0.8r / s to 1r / s within the time data of 0.5s, then the fluctuation speed data is +0.4 with -0.4 , the speed difference data is 0.2r / s and -0.2r / s, and the affected time data is 2.52s-3.52s. If the initial position is A, then at 2.52s, the position in contact with the grinding disc is 0.52 circles after two circles. This is the starting point. In the subsequent 1s, it drops from 1r / s to 0.8r / s and then rises back to 1r / s. The affected position is 0.52 circles to 0.52+0.9=1.42 circles, which is the fluctuation position interval. The corrected speed data is obtained according to the fluctuation position interval and the speed difference data and output to the driving source of the penetration rod 11, and then grinding compensation is performed on the position corresponding to the fluctuation position interval.

[0067] Reference Figure 7 , further comprising the following steps:

[0068] S2. Determine the non-fluctuating position interval through the fluctuating position interval and the preset overall position interval;

[0069] S21, determining the acceleration position interval through the fluctuation speed data and the fluctuation position interval;

[0070] S22, determining and outputting the inverse correction speed data through the non-fluctuation position interval, the speed difference data, the acceleration position interval, and the temporarily stored data, and the processed signal includes the inverse correction speed data.

[0071] In detail: if the fluctuation position interval is [0.52 laps, 1.42 laps], the overall position interval is [0, 1 lap], and the non-fluctuation position interval is [0.42 laps, 0.52 laps], the acceleration position interval is the position interval of acceleration or deceleration when affected, and in the example of this embodiment, the acceleration position interval is [0.52 laps, 0.92 laps] when decelerating, and [0.92 laps, 1.42 laps] when accelerating, that is, in the position interval [0.52 laps, 0.92 laps], the sphere is affected from 1r / s is reduced to 0.8r / s, and in the position interval [0.92 circle, 1.42 circle], the ball is ground at a speed of 0.8r / s to 1r / s, and in the remaining position interval [0.42 circle, 0.52 circle], the ball is ground at a speed of 1r / s. If it is necessary to compensate for the grinding of the ball surface to the same degree, the corresponding processing signal containing the correction speed data is output to the driving source of the penetration rod 11. At this time, there are two calculation methods:

[0072] The first method is to grind the ball at a speed of 0.8r / s to 1r / s in the position interval [0.52, 0.92], and at a speed of 1r / s to 0.8r / s in the position interval [0.92, 1.42]. In the remaining position interval [0.42, 0.52], the ball is ground at a speed of 0.8r / s. At this time, through the correction of the last circle, the grinding degree of the whole surface of the ball is unified to 1.8 circles, that is, 0.9r / s.

[0073] The second method: the ball is subsequently ground at a speed increasing from 1r / s to 1.2r / s in the position interval of [0.52 circle, 0.92 circle], and ground at a speed decreasing from 1.2r / s to 1r / s in the position interval of [0.92 circle, 1.42 circle], and ground at a speed of 1r / s in the remaining position interval of [0.42 circle, 0.52 circle]. At this time, through the correction of the last circle, the grinding degree of the overall surface of the ball is unified to 2 circles of grinding, that is, 1r / s.

[0074] Reference Figure 8 , further comprising the following steps:

[0075] S3, determining expired data through dislocation judgment data, time data, and a preset time interval threshold;

[0076] S31 . Determine new temporary storage data through expired data and original temporary storage data, and replace the original temporary storage data to participate in calculation of processing signals.

[0077] In detail: If the misalignment judgment data is that no relative rotation has occurred, and the time interval threshold is set to 4s, then 4s after recording the 5s active speed data to form temporary storage data, the temporary storage data is determined to be expired data and deleted. For example: the active speed data from the 0th second to the 5th second are all 1r / s, then the corresponding temporary storage data is formed, and the active speed data from the 5th second to the 10th second is formed as the next temporary storage data, and at the 9th second, the temporary storage data formed from the 0th second to the 5th second is determined to be expired data and deleted.
