Referring to fig. 1 to 6, fig. 1 is a cross-sectional view of a disc-like workpiece to be tested in the prior art; fig. 2 is a schematic structural view of a jacking and clamping tool provided by the present invention; FIG. 3 is a front view of FIG. 2; FIG. 4 is a side view of FIG. 2; FIG. 5 is a cross-sectional view of FIG. 4; fig. 6 is a schematic view of the structure of the chuck in fig. 2.

The utility model provides a jacking dress card frock, as shown in figure 2 and figure 3, this jacking dress card frock includes: a base 01; a spindle 04 penetrating the base 01; a tray 03 sleeved on the main shaft 04 and used for supporting the disc type workpiece; the chuck 02 is arranged at the top of the main shaft 04, provided with claws 021 and used for clamping the inner ring of the tray 03 by the claws 021; and the driving cylinder 05 is arranged below the base 01 and used for driving the tray 03 to move upwards along the main shaft 04 to the claws 021. Specifically, the tray 03 is annular and is sleeved on the main shaft 04, wherein the inner ring of the tray 03 preferably has the same shape as the outer contour of the cross section of the main shaft 04, the outer contour of the main shaft 04 is preferably perfect circle, and the main shaft 04 is preferably vertically arranged.

Before that, a process of fixing the disc workpiece and detecting the measuring points a to J by the jacking and clamping tool is described, wherein positions of the measuring points on the disc workpiece are shown in fig. 1. Firstly, clamping a disc workpiece by using a mechanical arm, placing the disc workpiece on a chuck 02, clamping the hole wall of a shaft hole of the disc workpiece by using a clamping claw 021 on the chuck 02 to enable all measuring points A to J to be exposed to the outside, then controlling the chuck 02 to rotate, aligning a probe of a detecting instrument to the measuring points A to J according to a certain sequence (such as letter sequencing), sequentially detecting the measuring points, and if a certain measuring point is detected to have a defect, taking down the unqualified disc workpiece and detecting the next disc workpiece to be detected.

If no defect is found from a measuring point A to a measuring point J, the measuring point K to a measuring point O needs to be further detected, but the bottom surface of the disc workpiece is attached to the claws 021 at the moment, the probe of the detector cannot carry out 360-degree all-around detection on the measuring point on the lower bottom surface of the disc workpiece, in order to solve the problem, the jacking clamping tool drives the tray 03 to move upwards along the main shaft 04 to the positions of the claws 021 by driving the cylinder body 05, and the claws 021 release the disc workpiece, so that the tray 03 can hold the disc workpiece up, the disc workpiece is separated from the claws 021, the lower bottom surface of the disc workpiece is higher than the claws 021, the whole circumference corresponding to the measuring point K to the measuring point O can be exposed, then the chuck 02 is controlled to rotate, the tray 03 and the disc workpiece on the tray 03 rotate together with the chuck 02, and meanwhile, the probe of the detector extends into the space between the disc workpiece and the claws 021 from the shaft hole of the disc workpiece, aligning the probe to a measuring point K to a measuring point O according to a certain sequence (such as letter sequencing), sequentially detecting the measuring points, taking down the unqualified disc workpiece if a certain measuring point is detected to have a defect, and detecting the next disc workpiece to be detected again; if all the measuring points of the disc type workpiece have no defects, the qualified disc type workpiece is taken down to carry out other detection or package delivery on the qualified disc type workpiece, and the detection on the next disc type workpiece to be detected is restarted.

It can be seen that the jacking clamping tool can detect two bottom surfaces of the disc type workpiece in a whole circle only by clamping the disc type workpiece once. The time for clamping the tray 03 by the claws 021 and the time for clamping the disc workpieces by the claws 021 for the second time are almost the same, and the time consumed for driving the tray 03 to ascend to the claws 021 is far less than the time consumed for taking off the disc workpieces and turning the disc workpieces by 180 degrees and putting the disc workpieces on the chuck 02 again by the mechanical arm, so that the jacking clamping tool shortens the time consumed for detecting each disc workpiece, and improves the detection efficiency.

It should be noted that the tray 03 merely supports and supports the disc-like workpiece, and no fixing connector is provided for fixing the disc-like workpiece, that is, the disc-like workpiece rotates together with the tray 03 by a frictional force, and in order to prevent the disc-like workpiece from being separated from the rotation center by an excessive centrifugal force, the rotation speed of the chuck 02 should be controlled so that the disc-like workpiece does not deviate when rotating with the tray 03.

It can be understood that if the tray 03 needs to be moved to the claws 021, the diameter of the chuck 02 should be smaller than or equal to the diameter of the inner ring of the tray 03, so that the tray 03 can pass over the chuck 02 to reach the height positions of the claws 021; in order to enlarge the space between the disc workpiece and the claw 021 after the disc workpiece is lifted, so that the probe of the detector extends to the position from the measuring point K to the measuring point O on the disc workpiece, if the height of the tray 03 is greater than the thickness of the claw 021, the tray 03 is moved to the position where the claw 021 is tightly clamped on the lower part of the inner ring of the tray 03, and the horizontal height of the disc workpiece is relatively increased; if the height of the tray 03 is smaller than the thickness of the claws 021, the tray 03 should be moved to a position where the tray 03 is clamped by the parts of the claws 021 that are close to each other, so that the horizontal height of the disc-like workpiece is relatively increased.

In order to ensure the stability of the jaws 021 on the chuck 02 in consideration that the diameter of the inner ring of the pallet 03 is much larger than the diameter of the axial hole of the disc-like workpiece, as shown in fig. 6, the jaws 021 include: a second clamping part 0212 of the first clamping part 0211 arranged from top to bottom in sequence; compared with the vertical outer contour of the first clamping portion 0211, the vertical outer contour of the second clamping portion 0212 is located farther away from the axis position of the chuck 02, so that the first clamping portion 0211 is used for clamping the shaft hole of the disc-like workpiece, and the second clamping portion 0212 is used for clamping the inner ring of the tray 03. Specifically, the first clamping portion 0211 and the second clamping portion 0212 are integrally arranged, the first clamping portion 0211 clamps the shaft hole of the disc workpiece through the vertical outer contour of the first clamping portion, the bottom surface of the disc workpiece abuts against the upper surface of the second clamping portion 0212, the second clamping portion 0212 clamps the inner ring of the tray 03 through the vertical outer contour of the second clamping portion, and then when the claw 021 clamps the tray 03, most of the claw 021 is located on the chuck 02, so that the stability of the claw 021 is guaranteed.

As shown in fig. 2 and 3, this jacking dress card frock still includes: the supporting seat 06 is arranged at the bottom of the tray 03, connected with the telescopic rod 051 of the driving cylinder body 05 and used for supporting the tray 03 to move upwards; the supporting seat 06 is sleeved on the main shaft 04, and a first bearing for the tray 03 to rotate is arranged between the supporting seat 06 and the tray 03. If the size of the tray 03 is too large, correspondingly, the mass of the tray 03 is large, and the inertia of the tray 03 is also large, the tray 03 cannot be fixed by the chuck 02, the control of the rotation of the tray 03 driven by the chuck 02 is also not facilitated, and the starting and stopping of the rotation state and the quick adjustment of the rotation speed cannot be realized; if the size of the tray 03 is too small, the fit of the tray 03 with the driving cylinder 05 is not facilitated. Consequently, support tray 03 along main shaft 04 up-and-down motion through setting up supporting seat 06 for the size of tray 03 need not too big can realize with the assembled connection of drive cylinder body 05, and when chuck 02 fixed tray 03, the great supporting seat 06 of size can not be along with the chuck 02 motion, and makes chuck 02 rotate on supporting seat 06 through first bearing, makes the size of tray 03 need not too big can realize the rotatory quick control to tray 03.

It can be understood that if the supporting seat 06 is not provided, the driving cylinder 05 needs to retract the telescopic rod 051 into the driving cylinder 05 when the driving tray 03 reaches the vicinity of the claw 021, in order to avoid the rotation of the tray 03 and the friction of the telescopic rod 051 of the driving cylinder 05, but this will make the chuck 02 bear the gravity of the tray 03. After setting up supporting seat 06, telescopic link 051 need not the withdrawal to make supporting seat 06 bear the weight of tray 03 and can also guarantee the rotation of tray 03 through first bearing, make jack catch 021 need not to bear the weight of tray 03, prolonged chuck 02's life.

It should be noted that the driving cylinder 05 is preferably an air cylinder, and the extension and retraction of the telescopic rod 051 are controlled by air intake and air discharge of the air cylinder, but the driving cylinder 05 may also be other power components capable of realizing extension and retraction of the telescopic rod 051, such as a hydraulic cylinder.

Because the telescopic rod 051 is only connected with one end of the supporting seat 06, the driving force applied to the supporting seat 06 when the telescopic rod 051 drives the supporting seat 06 to move is not uniformly distributed, so that the movement of the supporting seat 06 is not stable, namely the supporting seat 06 has the tendency of moving obliquely along the main shaft 04. In order to solve the above problem, as shown in fig. 2 to 5, the jacking and clamping tool further includes a guide rod 07 vertically penetrating through the base 01, fixedly connected with the support seat 06, and used for limiting the movement direction of the support seat 06. Particularly, the bottom fixed connection of guide bar 07 and supporting seat 06, when telescopic link 051 drive supporting seat 06, by bearing the horizontal component of drive power between guide bar 07 and the base 01, and supporting seat 06 only bears the vertical component of drive power to play the effect of stabilizing the supporting seat 06 motion.

As shown in fig. 3 and 4, the jacking and chucking tool further includes a motor 08 disposed below the base 01, connected to the bottom of the spindle 04, and configured to allow the spindle 04 to drive the chuck 02 to rotate.

Wherein, a motor bracket 081 is arranged below the base 01, so that the motor 08 is fixed below the base 01 through the motor bracket 081.

As shown in fig. 3 and 5, the jacking and clamping tool further includes an oil tank 09 disposed below the main shaft 04 and used for the main shaft 04 to drive the clamping jaws 021 to open and close. Specifically, the chuck 02 in the jacking and clamping device is specifically a hydraulic chuck 02, and the claw 021 on the chuck 02 is controlled to be opened by adjusting the oil supply direction of the oil tank 09 so as to clamp the disc workpiece or the tray 03, or the claw 021 is controlled to be closed so as to loosen the disc workpiece or the chuck 02. Wherein, the oil tank support 091 is arranged below the base 01, and the oil tank 09 is fixed below the base 01 through the oil tank support 091.

It is understood that, since the oil tank 09 is provided directly below the main shaft 04, the driving cylinder 05 and the motor 08 are both provided below the oil tank 09, and a transmission belt is required between the motor 08 and the main shaft 04 to transmit the torque of the motor 08 to the main shaft 04 through the transmission belt.

As shown in fig. 4, the spindle 04 includes: a housing 041 provided at the base 01; a rotating shaft 043 disposed inside the housing 041 and penetrating the base 01 to drive the chuck 02 to rotate; wherein, the top of the rotating shaft 043 is connected with the chuck 02, and the bottom of the rotating shaft 043 is connected with the transmission belt; a second bearing 042 provided between the housing 041 and the rotation shaft 043; a pull rod 044 which is arranged inside the rotating shaft 043, penetrates through the base 01 and is used for driving the claws 021 to open and close; wherein, the top of the pull rod 044 is connected with the chuck 02 through a threaded joint 022, and the bottom of the pull rod 044 is connected with the oil tank 09.
