Description

TECHNICAL FIELD

[0001] The present application relates to the field of precision machinery, in particular to a precision machining measurement error prevention device. BACKGROUND

[0002] Measurement is to describe the observed phenomenon with data according to a certain law, that is, to make a quantitative description of things. Measurement is a quantitative process of non-quantitative objects, and measurement error refers to the range difference between the actual measurement value of the measuring instrument and the given standard value of the part. The measurement error prevention device controls the actual measurement value of the part, so that the actual measurement value of the part gradually approaches the given standard value of the part, thereby assisting the production staff to operate the part processing technology according to the measured part value.

[0003] Then, the existing measurement error prevention device has a series of deficiencies in use, for example:

[0004] Firstly, most of the existing measurement error prevention devices are fixed as a whole. During the actual part measurement process, the measurement error prevention device with scales is aligned with one side of the part to be measured, and then the measurement operation is performed. The existing measurement error prevention device can only realize the measurement of one side after the measurement of the other side. This measurement method not only consumes time and effort, but also has the problem that the measurement method is usually a manual measurement of the part value by holding the measurement error prevention device. During the measurement, the unstable manual holding will cause the position of the measured part to deviate, or the measured part value error will be large, the measured value will not be accurate, and the production operation of the measured part will be greatly affected.

[0005] Secondly, the existing measurement error prevention device can only assist the operator to measure the value of each side of the part. During the measurement of the part, there will be residual dust on the part. The existing measurement error prevention device cannot clean the dust on the part, so manual cleaning of the dust on the part is required. However, due to the residual dust attached to the hands, the part cannot be held stably during the measurement, which leads to low measurement accuracy, large error, and even measurement failure of the part. This not only cannot achieve the effect of measuring the part, but also may cause the device and the part to fall down and be damaged due to unstable holding, and consumes time and effort. The function is single.

[0006] Finally, while measuring the parts, some processes need to be processed on the measured parts, for example, the determination of the punching position of the parts, that is, first measuring the parts, and then the operator finds the position to be punched, and then the drilling machine is used for punching operation. The existing measurement error prevention device can only measure the parts, but cannot assist the operator in punching the parts. When measuring and punching the parts, the parts will not be accurately measured due to the instability of the manual holding of the measurement error prevention device, and the error is large, which will cause the punching position to deviate, the size of the hole to be different, the punching to be deformed, and other problems. In the process of punching, the drill bit will be deformed due to the debris generated by the drill bit when drilling, which will affect the drilling of the drill bit and the operation of the operator to assist the punching operation.

[0023] (Three) beneficial effects

[0024] Compared with the known prior art, the technical scheme provided by the present application has the following beneficial effects,

[0025] 1、By setting the precise measuring mechanism, when the screw rod one and the screw rod two stop rotating, the sliding plate one and the sliding plate two stop synchronously and keep the status, which increases flexibility and solves the problem that the measuring error prevention device cannot keep stable measurement of parts when measuring parts. On the other hand, the sliding block four and the sliding block five slidingly connected on the sliding plate one and the sliding plate two can better cooperate with the stable sliding of the sliding plate one and the sliding plate two. Since the central shaft of the sliding block four and the sliding block five is fixedly connected, the sliding plate one and the sliding plate two form a mutually stable sliding form. Moreover, through the linkage of the arrow at the rear end of the sliding plate one and the sliding plate two and the scale on the scale ruler below the arrow, the sliding plate one and the sliding plate two can be moved to be flush with the edges of the parts. At this time, the measurement value of the parts can be read out, which improves the efficiency of measuring parts and solves the problems of large measurement error and measurement failure caused by unstable handheld measurement of the original device, and makes it more convenient for the operator to measure parts.

[0026] 2、In addition, through the linkage of the soil-shaped sliding block slidingly connected on the hollow scale plate and the four springs, stable up-down sliding is realized. When the soil-shaped sliding block slides, it can also drive the fixedly connected hollow disc and the internal parts of the hollow disc to move up and down, which assists the drill bit screwedly connected at the bottom of the rotating rod to stably rotate and drill, increases the stability of drilling, solves the problem that the original device cannot accurately and stably drill the measured parts, and also realizes real-time reading of the depth measurement value of drilling while the soil-shaped sliding block slides by cooperating the scale on the hollow scale plate with the pointer on one side of the soil-shaped sliding block, which makes it more convenient for the operator to control the depth of drilling. Moreover, a power source can be externally connected through the groove opened at the top of the rotating rod to provide power for drilling, which assists the operator in drilling work.

[0027] 3、The rotating knob can also be used to control the rotation of the screw rod three, and thus control the opening and closing of the fixed block and the connecting block, so as to control the opening and closing of the semicircular fixed disc and the semicircular movable disc. The two clamping blocks fixedly connected on the inner side of the semicircular movable disc are clamped and matched with the two clamping grooves opened at the bottom of the rotating rod, so that the rotating rod can drive the semicircular movable disc to rotate, thereby driving the semicircular fixed disc in the combined state to stably rotate. The sliding block three slidingly connected in the hollow disc is fixedly connected to the fixed block, so that the sliding block three can slide in the slide groove opened in the hollow disc, which more conveniently assists the drill bit to stably drill.

[0028] 4. By setting the cleaning mechanism, under the movement of the sliding plate 1 and the sliding plate 2 on the accurate measuring mechanism, the telescopic movement of the telescopic brush 1 and the telescopic brush 2 can be controlled, which increases flexibility and solves the problem that the original device cannot clean the dust on the parts. The telescopic position of the telescopic brush 1 and the telescopic brush 2 can be adjusted by the movement of the sliding plate 1 and the sliding plate 2 to clean parts of different lengths. Since the fixed block is fixedly connected to the bottom of the sliding plate 1 and the sliding plate 2, the fixed block 2 can provide a stable telescopic environment for the telescopic brush 1 and the telescopic brush 2, making it more convenient for operators to operate the dust removal operation on the surface of the parts.

[0029] 5. By setting the blowing mechanism, under the rotation of the rotating wheel and the rotating shaft, the connecting rod 1 and the connecting rod 2 start to rotate reciprocatingly to push and pull the push rod. Since one end of the push rod is connected to the blowing cylinder in a piston manner, the push rod can drive the blowing cylinder to push and pull the air pressure movement, and the blowing gun is provided with continuous blowing power, which increases flexibility and solves the problem that the original device cannot clean the debris after punching the parts. Since the other end of the air pipe connected to the blowing cylinder penetrates the bottom of the sliding block 5, the blowing gun can more conveniently blow the debris, and the operator can more conveniently perform the punching and debris cleaning operation.

In the initial state, the slider 204 and the slider 207 threaded on the screw rod one 201 and the screw rod two 208 are located at the flush position of the L-shaped hollow carrier box 203, then the precision measuring mechanism 200 starts to work, the screw rod one 201 rotatingly connected in the L-shaped hollow carrier box 203 is manually rotated, and the slider 204 is driven to slide to the other edge of the part, at the same time, the slider 204 drives the sliding plate one 205 fixedly connected at the top to slide, and the slider four 223 is slidingly connected in the sliding groove opened in the inner wall of the sliding plate one 205, because the middle shaft at the bottom of the slider four 223 is fixedly connected with the middle shaft at the top of the slider five 224, and the slider five 224 is slidingly connected in the sliding groove opened in the inner wall of the sliding plate two 206, so that the sliding plate one 205 slides on the sliding plate two 206 while driving the slider four 223 to move, when one side of the sliding plate one 205 slides to the flush position of the edge of the part, the screw rod one 201 stops rotating, so that the sliding plate one 205 remains in a stable state, at this time, the scale value pointed by the arrow arranged at the rear end of the sliding plate one 205 can be read, similarly, the screw rod two 208 rotatingly connected in the L-shaped hollow carrier box 203 is manually rotated, and the slider two 207 is driven to slide to the other edge of the part, at the same time, the slider two 207 drives the sliding plate two 206 fixedly connected at the top to slide, and the sliding plate two 206 slides on the sliding plate one 205 while driving the slider five 224 to move, when one side of the sliding plate two 206 slides to the flush position of the edge of the part, the screw rod two 208 stops rotating, so that the sliding plate two 206 remains in a stable state, at this time, the scale value pointed by the arrow arranged at the rear end of the sliding plate two 206 can be read, and the measurement is completed. The positions of the slider four 223 and the slider five 224 are moved by rotating the screw rod one 201 and the screw rod two 208 again, and the rotation of the screw rod one 201 and the screw rod two 208 is stopped when the slider four 223 and the slider five 224 reach the specified drilling position of the part, so that the slider four 223 and the slider five 224 are in a stable state;

[0067] Second step, the cleaning mechanism 300 on the telescopic brush one 301 and telescopic brush two 302 one end is fixedly connected at the bottom of the slider five 224, and the other end of telescopic brush one 301 is fixedly connected at the bottom of the sliding plate one 205, and the other end of telescopic brush two 302 is fixedly connected at the bottom of the sliding plate two 206, when the sliding plate one 205 moves forward, the sliding plate one 205 can drive telescopic brush one 301 to brush the dust of the part transversely forward, when the edge of the sliding plate one 205 is flush with the edge of the part, the dust brushing work of telescopic brush one 301 is finished, similarly, when the sliding plate two 206 moves right, the sliding plate two 206 can drive telescopic brush two 302 to brush the dust of the part transversely right, when the edge of the sliding plate two 206 is flush with the edge of the part, the dust brushing work of telescopic brush two 302 is finished;

[0068] Then manually rotate the knob 225, the screw rod three 215 began to rotate, because the screw rod three 215 is threaded and through the inner wall of the connecting block 214, so that the screw rod three 215 in rotation, make connecting block 214 along the screw thread face of the screw rod three 215 fixed block 216 close to the side of the semicircular movable disc 217 moves, in turn realize the connecting block 214 in the rotation of the screw rod three 215 and fixed block 216 gradually merged, also make the semicircular movable disc 217 inner wall fixed connection of two clamping block 219 clamping in the bottom of the two clamping groove 226 opened in the rotating rod 220, make semicircular movable disc 217 and rotating rod 220 fixed, also make the rotating rod 220 side fixed connection of semicircular fixed disc 218 and semicircular movable disc 217 form a fixed posture, so as to provide stable support environment for the rotation of the rotating rod 220, also can provide stable drilling force support environment for the drill bit 222 downward rotation drilling, and the fixed block 216 side fixed connection of T-shaped slider 213 is slidingly connected in the slide groove opened in the inner wall of the hollow disc 212, then the bottom of the rotating rod 220 and the drill bit 222 is a threaded connection, in order to realize the use of drill bit 222 after the drill bit 222 is disassembled and replaced, then an external existing rotating power gun in the groove opened in the top of the rotating rod 220, start the existing rotating power gun, make the rotating rod 220 drive semicircular movable disc 217 and semicircular fixed disc 218 rotation and drive the drill bit 222 at the bottom of the rotating rod 220 begin to rotate downward drilling, at the same time, T-shaped slider 213 begins to slide in the hollow disc 212, rotating power gun down pressure force synchronous drive hollow disc 212 begins to move downward, at the same time drive the two earth shaped slider 211 fixedly connected on both sides of the hollow disc 212 downward sliding, and the four springs 210 fixedly connected on both sides of the two earth shaped slider 211, can realize the stable downward movement of the two earth shaped slider 211, and the pointer 221 fixedly connected on one side of the two earth shaped slider 211, can read the depth of the drill bit 222 drilling through the scale on the hollow scale plate 209 while moving downward;

One end of the fixed plate 406 is fixedly connected to the bottom of the hollow disk 212, and the other end is sleeved on the outer wall of the rotating shaft 405, in order to provide a stable supporting environment for the rotation of the rotating shaft 405. At the same time, the rotating shaft 405 can also drive the connecting rod 1 407 fixedly installed on one end of the rotating shaft 405 to rotate, and then the connecting rod 1 407 drives the connecting rod 2 408 to start rotating and pushing and pulling the push rod 409 back and forth. Since the push rod 409 and the blowing cylinder 402 are piston-connected, the push rod 409 can drive the blowing cylinder 402 to move. The air cylinder 402 performs a push-pull, inflating and compressing air movement, and provides continuous blowing power for the air blowing gun head 410, which not only increases a certain degree of flexibility, but also solves the problem that the original device cannot clean the debris after the parts are punched. Since the other end of the air pipe 403 connected to the air blowing cylinder 402 passes through the bottom of the slider 5 224, it can not only deliver stable blowing power to the air blowing gun head 410, but also assist the air blowing gun head 410 in blowing debris cleaning operations on the drill bit 222 and the drilled hole, but also provide a certain supporting environment for the air blowing gun head 410, and further assist the operator in the drilling debris cleaning operation. When the drilled debris is cleaned, the spiral rod 1 201 and the spiral rod 2 208 are rotated again, so that the retractable brush 1 301 and the retractable brush 2 302 perform a secondary cleaning of the dust on the parts. When the slider 1 204 and the slider 2 207 reach the initial position, the rotation of the spiral rod 1 201 and the spiral rod 2 208 is stopped, the parts are taken away, and the measurement processing is completed.
