Description

Technical Field

[0001] The invention relates to a device for measuring the size of a top hammer blank. Background Art

[0002] In order to improve production efficiency, automated equipment is often used to measure the dimensions of top hammer blanks and perform post-measurement processing and grinding. Generally, a transport mechanism is used to move the top hammer blanks on the production line to the detection mechanism side, and then a measuring device is used to measure one or more dimensions of the top hammer blanks.

[0003] Chinese patent application number 201720625290.8 discloses a device for measuring the upper size of a top hammer blank, including a micrometer and a standard measuring block. The middle of the standard measuring block is provided with fixing rod through holes distributed in the vertical direction. The fixing rod of the micrometer is installed in the fixing rod through hole, and the measuring head faces downward. The bottom of the standard measuring block is provided with a measuring block inner angle adapted to the inclined surface of the top hammer blank. The standard measuring block is processed by linear cutting according to the upper size and inclined surface angle required by the customer.

[0004] The above patent sets a standard measuring block to correspond to the top hammer blank to be measured. As long as the position and height of the standard measuring block are kept well, the top hammer blank to be measured can be positioned, the offset of the top hammer blank to be measured can be corrected, and the high-precision positioning of the top hammer blank can be ensured, thereby improving the dimensional detection accuracy. However, the specifications and sizes of the top hammer blanks are different each time, and standard measuring blocks of different specifications and sizes need to be replaced for each batch, and when the offset angle of the top hammer blank is large, the standard measuring block is easy to get stuck. Summary of the invention

[0005] The object of the present invention is to provide a device for measuring the size of a top hammer blank, which is easy to use and convenient for aligning and positioning the top hammer blank, thereby improving the accuracy of detecting the size of the top hammer blank.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a device for measuring the size of a top hammer blank, comprising a detection component for measuring the size of a top hammer blank and a first supporting seat for supporting the top hammer blank, a top hammer inclined surface correction mechanism and a first top hammer center position correction mechanism are arranged on the side of the first supporting seat, the top hammer inclined surface correction mechanism and the first top hammer center position correction mechanism both comprise a first driver and a correction block fixed to the output end of the first driver, the correction block approaches or moves away from the first supporting seat under the action of the first driver, the correction surface of the correction block of the top hammer inclined surface correction mechanism is tilted and used for surface contact or line contact with the large inclined surface of the top hammer blank to be measured, and the correction surface of the correction block of the first top hammer center position correction mechanism is tilted and used for surface contact or line contact with the outer cylindrical surface of the top hammer blank to be measured.

[0007] The scheme of the present invention makes the correction surface of the correction block of the top hammer bevel correction mechanism contact with the large bevel of the top hammer blank, and then the top hammer blank can be moved to the set position through the first top hammer center position correction mechanism. When the correction block of the first top hammer center position correction mechanism pushes the top hammer blank to move, the top hammer blank will be angularly offset at the contact surface with the correction block of the top hammer bevel correction mechanism, so as to adaptively adjust the angle to complete the angle offset correction and ensure the subsequent dimensional measurement accuracy. The correction block of the scheme of the present invention can be positioned with most top hammer blanks through line contact, and can be in surface contact with a small number of top hammer blanks, so it is suitable for most top hammers. Among them, the outer circle inclination angle of most (98%) top hammer blanks is 1.5°, and the outer circle inclination angle of a small number (2%) of top hammer blanks is 2°. The correction surface of the correction block of the first top hammer center position correction mechanism of the present invention is 1.5°, which can be suitable for most top hammer blanks, thereby reducing the number and frequency of replacement of the correction block, so as to facilitate measurement and use. Among them, almost all the large bevels of the top hammers are 46°. After the position of the correction block of the top hammer bevel correction mechanism is adjusted, it can be used for adaptive correction of most top hammer blanks.

[0008] Preferably, the first support seat includes a base and a support plate, the support plate is rotatably fixed to the base via a bearing, and the support plate is supported on the upper side of the base via a plurality of support steel balls at a position offset from the center. By making the support plate rotatably fixed to the base, and the support plate supported on the base via steel balls, the friction force when the support plate rotates can be reduced, so that the top hammer blank can be supported to rotate under the action of the hammer bevel correction mechanism.

[0009] Preferably, it also includes a second support seat, which is arranged at the output end of the rotation driver, and the rotation driver is used to drive the second support seat to rotate. The first support seat and the second support seat are provided with a transport mechanism for transferring the top hammer blank between the first support seat and the second support seat.

[0010] After the center positioning and angle correction of the top hammer blank are achieved through the mechanism on the first support seat side, the transport mechanism transfers the top hammer blank from the first support seat to the second support seat side; by making the second support seat and the rotary driver rotate, it is convenient to obtain two or even more sets of data in combination with the profilometer, and the measured data can be compared to determine whether the data is reasonable. If the data detected multiple times are close, the top surface and outer cylindrical surface size data of the top hammer blank can be determined by the average value of the data; if the data differ greatly, since the size difference of the top hammer blanks produced by the mold is small, it means that the top hammer blank has an angle or position deviation.

[0011] The first support seat and the second support seat realize different functions, and different process flows of two top hammer blanks can be carried out simultaneously, thereby improving production efficiency, and the rotary drive can adopt a lower-cost existing rotator, such as a four-part pneumatic dividing plate.

[0012] Preferably, a handling mechanism and a transmission mechanism are provided on the side of the first support seat, and a second top hammer center position correction mechanism is provided downstream of the transmission mechanism, and the second top hammer center position correction mechanism has the same structure as the first top hammer center position correction mechanism. Through two positionings, the position of the top hammer blank before loading and after unloading can be more accurately guaranteed to improve the measurement accuracy.

[0013] Preferably, a transport mechanism is provided on the side of the first support seat, and the transport mechanism includes a vertical displacement driver, a lateral displacement driver and a suction cup, the suction cup is a hood-shaped structure with a downward opening, and the suction cup is composed of a plurality of suction cup monomers, and the plurality of suction cup monomers are centrally symmetrically arranged, and the inner sections of the corresponding top hammer blank top surfaces of all suction cup monomers are connected to each other, and there is a gap between the outer sections of the corresponding top hammer blank large inclined surfaces of adjacent suction cup monomers. The suction cup has a gap extending in the radial direction, so that the outer section of the suction cup monomer can fit with the large inclined surface, thereby improving the suction and clamping effect of the suction cup on the top hammer.

[0014] Preferably, the suction cup is provided with a plurality of suction holes at the top surface, small inclined surface and large inclined surface corresponding to the top hammer blank, and the suction holes corresponding to the large inclined surface include side suction holes located on both sides and middle suction holes located relatively below the side suction holes.

[0015] Preferably, the detection component is equipped with a second driver, and the detection component is translated under the action of the second driver; the second driver is arranged at the output end of the third driver, and the translation direction of the detection component under the action of the second driver forms an angle with the translation direction under the action of the third driver. When the detection component includes a profiler, it is convenient to adjust the position of the profiler. At the same time, it can also realize the reservation of space on the side of the support seat, which is convenient for loading and unloading.

[0016] Preferably, the detection assembly includes a detection plate, one end of which extends downward, and the other end of which is connected to one end of a movable rod, which is slidably arranged at a through hole of a fixed plate, a spring is provided at the fixed plate, and the movable rod has a tendency to move along its own axial direction under the action of the spring, and the other end of the movable rod is connected to a detection analyzer or a displacement sensor is provided at the fixed plate.

[0018] Preferably, the first driver is a cylinder, the cylinder diameter of the top hammer bevel correction mechanism is less than 10 mm, the air pressure used is 0.2-0.3 MPa, and the cylinder extension speed needs to be less than 3 mm / s. The cylinder diameter needs to be less than 10 mm, and the air pressure used is 0.2-0.3 MPa to prevent the cylinder diameter from being too large, which may cause the bottom of the small-sized top hammer to deviate when the top hammer specification is changed; by making the cylinder extension speed less than 3 mm / s, a certain amount of time is given to the self-rotation correction of the top hammer blank when the correction block contacts the top hammer blank.

[0019] The present invention can realize position adjustment and angle correction of the top hammer blank, can improve the subsequent size detection accuracy of the top hammer blank, and the present invention also has the advantage of improving production efficiency.
