Detailed Description
In order to explain technical contents, structural features, and effects of the present invention in detail, the following detailed description is given with reference to the embodiments and the accompanying drawings.
Referring to fig. 1 to 5, an embodiment of a jig 1 for detecting an offset of a hole axis includes a base 10, a first substrate 20, a second substrate 21, a fixing device 30, and a detecting device 40.
The first substrate 20 is provided with one of the positioning shaft 201 and the positioning hole 211, the second substrate 21 is provided with the other of the positioning shaft 201 and the positioning hole 211, when the second substrate 21 is assembled on the first substrate 20, the positioning shaft 201 is inserted into the positioning hole 211, the fixing device 30 is used for fixing the first substrate 20 on the base 10, and the detecting device 40 is used for detecting the maximum relative displacement between the first substrate 20 and the second substrate 21 when the second substrate 21 is linearly pushed after the second substrate 21 is assembled on the first substrate 20, so as to detect the offset of the positioning hole 211 and/or the positioning shaft 201.
In the hole axis offset detection jig 1 of the embodiment of the present invention, the fixing device 30 fixes the first substrate 20 on the base 10, the second substrate 21 is assembled on the first substrate 20, so that the positioning shaft 201 is inserted into the positioning hole 211, the detection device 40 is used for detecting the maximum relative displacement between the first substrate 20 and the second substrate 21 when the second substrate 21 is pushed linearly, and can accurately detect the offset of the positioning hole 211 and/or the positioning shaft 201, so as to accurately judge whether the offset of the positioning hole 211 and/or the positioning shaft 201 meets the standard, and the hole axis offset detection jig 1 of the embodiment of the present invention has a simple structure.
Therefore, when the hole axis offset detection jig 1 provided by the embodiment of the invention is used for detecting the offset of the positioning shaft 201 and the positioning hole 211 for positioning, whether the offset of the positioning shaft 201 and/or the positioning hole 211 exceeds the standard can be accurately detected, so that whether the abrasion loss of the positioning shaft 201 and/or the positioning hole 211 exceeds the standard can be judged, the scrapping treatment can be timely carried out on the workpiece with the abrasion loss exceeding the standard, and the problem that the positioning is inaccurate due to the continuous use of the workpiece with the abrasion loss exceeding the standard is solved. Of course, the hole axis offset detection jig 1 provided in the embodiment of the present invention may also be used for other purposes, such as performing qualified detection on the positioning shaft 201 and/or the positioning hole 211 in the production process, and the like.
Specifically, since the first substrate 20 is fixed on the base 10, when the second substrate 21 is pushed, the positioning shaft 201 and the positioning hole 211 will stop each other, so that the second substrate 21 cannot be pushed further, and when the first substrate 20 and the second substrate 21 are not pushed after being assembled, the positioning hole 211 and the positioning shaft 201 are not necessarily in a mutually stopped state, the second substrate 21 can be pushed linearly in a first direction to a first position where the positioning shaft 201 and the positioning hole 211 stop each other, and then the second substrate 21 can be pushed linearly in a second direction opposite to the first direction to a second position where the positioning shaft 201 and the positioning hole 211 stop each other, the detecting device 40 detects a relative displacement amount when the second substrate 21 is pushed linearly in the second direction from the first position to the positioning shaft 201 and the positioning hole 211 stop each other, so that the offset amount of the positioning hole 211 and/or the positioning shaft 201 can be accurately detected, and the detection of the offset of the positioning hole 211 and/or the positioning shaft 201 is quick and simple.
It can be understood that, when the first substrate 20 and the second substrate 21 are both workpieces put into use, the offset detected by the detection device 40 is the combined offset of the positioning hole 211 and the positioning shaft 201; when the first substrate 20 is a workpiece to be put into use and the second substrate 21 is a standard part not to be put into use, the offset amount detected by the detection device 40 is the offset amount of the positioning shaft 201; when the first substrate 20 is a standard component that is not put into use and the second substrate 21 is a workpiece that is put into use, the offset amount detected by the detection device 40 is the offset amount of the positioning hole 211. Therefore, the hole axis offset detection jig 1 according to the embodiment of the present invention can obtain the accurate offset of the positioning hole 211 and/or the positioning axis 201, and can further accurately determine whether the offset of the positioning hole 211 and/or the positioning axis 201 exceeds the standard.
The embodiment of the present invention does not limit the number of either one of the positioning shafts 201 and the positioning holes 211 on the first substrate 20 and the other one of the positioning shafts 201 and the positioning holes 211 on the second substrate 21. It can be understood that the hole axis offset detection jig 1 of the embodiment of the present invention can measure only one positioning axis 201 and one positioning hole 211 by plugging each positioning axis 201 and one positioning hole 211 at a time, so as to measure each positioning axis 201 and each positioning hole 211 one by one, thereby improving the accuracy of offset measurement; when the number of the positioning shafts 201 or the positioning holes 211 on the first substrate 20 and the number of the positioning holes 211 or the positioning shafts 201 on the second substrate 21 are two or more, when the first substrate 20 and the second substrate 21 are positioned, two or more positioning shafts 201 and positioning holes 211 may be correspondingly inserted at the same time, so that the hole axis offset detection jig 1 of the embodiment of the present invention may also be used to simultaneously and correspondingly insert two or more positioning shafts 201 and positioning holes 211 at the same time to measure the offset so as to improve the efficiency of measuring the offset.
As shown in fig. 1 to 3, the base 10 is provided with a mounting portion 11 for mounting the detection device 40, so as to facilitate mounting of the detection device 40.
Further, the mounting portion 11 is formed with a mounting groove 110, the detecting device 40 is mounted in the mounting groove 110, an opening 111 is opened on one side of the mounting groove 110 facing the first substrate 20 and the second substrate 21, and the detecting device 40 detects the maximum relative displacement between the first substrate 20 and the second substrate 21 through the opening 111. The detection device 40 is installed in the installation groove 110, so that the detection device 40 can be prevented from shaking or moving, and the detection device 40 can be ensured to measure accurately.
As shown in fig. 1 to 5, the detection device 40 may be provided as a dial indicator attached to the mounting portion 11, and a spindle 41 of the dial indicator is configured to be extendable and retractable in a pushed direction of the second base plate 21 to abut against the second base plate 21 at different positions. When the mounting portion 11 is formed with the mounting groove 110, the dial gauge body of the dial gauge is mounted in the mounting groove 110, and the spindle 41 of the dial gauge protrudes through the opening 111 to abut against the second base plate 21. Of course, the mounting groove 110 may not be formed on the mounting portion 11, and the dial indicator may be directly mounted on the mounting portion 11 and may be fixed to the mounting portion 11 by other fixing structures. The detection device 40 measures the relative displacement between the first substrate 20 and the second substrate 21 by using a dial indicator, so that the measurement precision is high, and the accurate offset of the positioning shaft 201 and/or the positioning hole 211 can be obtained more favorably.
Specifically, when the second substrate 21 is pushed linearly in a first direction until the second substrate cannot be pushed, the measuring rod 41 of the dial indicator abuts against the second substrate 21 and the dial indicator is set to zero, and then the second substrate 21 is pushed linearly in a second direction opposite to the first direction until the second substrate cannot be pushed, so that the measuring rod 41 of the dial indicator continues to abut against the second substrate 21, and at this time, the measurement value of the dial indicator is the offset of the positioning shaft 201 and/or the positioning hole 211.
As shown in fig. 1 and 5, in order to more accurately measure the offset of the positioning shaft 201 and/or the positioning hole 211, the hole shaft offset detection fixture 1 of the embodiment of the present invention may further measure the lateral offset and the longitudinal offset of the positioning shaft 201 and/or the positioning hole 211, respectively. In fig. 1, the first substrate 20 is transversely fixed on the base 10, the second substrate 21 is assembled on the first substrate 20, the positioning shaft 201 is inserted into the positioning hole 211, the measuring rod 41 of the dial indicator abuts against the second substrate 21, the second substrate 21 is firstly pushed towards one side of the dial indicator until the second substrate cannot be pushed, the dial indicator is set to zero, then the second substrate 21 is pushed towards one side away from the dial indicator until the second substrate cannot be pushed, the measuring rod 41 of the dial indicator is pushed to continue abutting against the second substrate 21, and the reading of the dial indicator is the transverse offset of the positioning shaft 201 and/or the positioning hole 211. In fig. 5, the first substrate 20 is longitudinally fixed on the base 10, the second substrate 21 covers the first substrate 20, the positioning shaft 201 is inserted into the positioning hole 211, the measuring rod 41 of the dial indicator abuts against the second substrate 21, the first substrate 20 and the second substrate 21 in fig. 5 rotate on the base 10 by 90 ° relative to the first substrate 20 and the second substrate 21 in fig. 1, similarly, the second substrate 21 is pushed to one side of the dial indicator until the second substrate cannot be pushed, the dial indicator is set to zero, then the second substrate 21 is pushed to one side away from the dial indicator until the second substrate cannot be pushed, the measuring rod 41 of the dial indicator is pushed to continue abutting against the second substrate 21, and the reading of the dial indicator is the longitudinal offset of the positioning shaft 201 and/or the positioning hole 211.
Of course, in the embodiment of the present invention, when measuring the offset, the measurement is not limited to the specific form, for example, the second substrate 21 may be pushed to the opposite side of the detection device 40 to be unable to be pushed, and then the second substrate 21 is pushed to the side of the detection device 40 to be unable to be pushed, the detection device 40 detects the displacement of the second substrate 21 when the second substrate 21 is pushed to the side of the detection device 40 to be unable to be pushed, so as to detect the offset of the positioning hole 211 and/or the positioning shaft 201, and the embodiment of the present invention is not limited thereto.
It is to be understood that the detecting device 40 of the embodiment of the present invention is not limited to the dial indicator, and may be configured as a distance measuring sensor, for example, which is mounted on the mounting portion 11 and is used for detecting a position change of the second substrate 21 to detect a maximum relative displacement amount between the first substrate 20 and the second substrate 21. When the mounting portion 11 is formed with the mounting groove 110, the distance measuring sensor is mounted in the mounting groove 110, and the distance measuring light, the ultrasonic wave, or the like is emitted to the other of the first substrate 20 and the second substrate 21 through the opening 111 opened in the mounting groove 110 to detect the position change of the second substrate 21, thereby enabling to detect the maximum amount of relative displacement between the first substrate 20 and the second substrate 21. Of course, the detecting device 40 according to the embodiment of the present invention may be any device capable of detecting the displacement amount, besides the dial indicator and the distance measuring sensor.
As shown in fig. 1 to 5, the fixing device 30 includes a sliding block 31 and a locking member 32, the sliding block 31 is configured to be slidable along the base 10 and can be locked and fixed on the base 10 by the locking member 32, a stop wall 33 is disposed on one side of the base 10, when the locking member 32 locks and fixes the sliding block 31, the first substrate 20 is sandwiched between the sliding block 31 and the stop wall 33, so that the first substrate 20 can be stably fixed on the base 10, and the first substrate 20 is prevented from being moved when the second substrate 21 is pushed, which may cause inaccurate offset measurement.
It is understood that the sliding block 31 and the stop wall 33 are respectively disposed at two sides of the region of the base for placing the first substrate 20 or the second substrate 21 to enable the fixed clamping of the first substrate 20 or the second substrate 21; the detecting means may be provided on the same side as the slider 31 or the stopper wall 33, or may not be provided on the same side as the slider 31 and the stopper wall 33.
Further, the slider 31 is convexly provided with a guiding protrusion 310, the base 10 is provided with a first sliding slot 311, the guiding protrusion 310 is slidably disposed on the first sliding slot 311, and when the locking member 32 locks and fixes the slider 31, the first substrate 20 is sandwiched between the slider 31 and the stop wall 33. One or more first sliding grooves 311 may be formed in the base 10, and the guide protrusion 310 protruding from the slider 31 is disposed corresponding to the first sliding grooves 311. Of course, the embodiment of the present invention does not limit the specific structure of the sliding block 31, for example, a sliding rail may be formed on the base 10, and a sliding groove capable of sliding along the sliding rail is formed on the sliding block 31 to drive the sliding block 31 to slide on the base 10, and so on.
Further, the locking element 32 includes a fixed handle 320 and a lock cylinder slider 321, the fixed handle 320 includes a connecting rod 3201 and a stopping portion 3202, the lock cylinder slider 321 is provided with a screw hole 3210, the base 10 is provided with a second sliding slot 112, the lock cylinder slider 321 is embedded in the second sliding slot 112 and can slide along the second sliding slot 112, the slider 31 is provided with a through hole 312, the connecting rod 3201 passes through the through hole 312 and is in threaded connection with the screw hole 3210, and when the connecting rod 3201 and the screw hole 3210 are screwed to the slider 31 and is fixedly clamped between the base 10 and the stopping portion 3202, the slider 31 is locked and fixed. The slider 31 is fixedly held between the base 10 and the stopper 3202 by the pressing force of the stopper 3202 on the slider 31. Of course, the locking element 32 of the embodiment of the present invention is not limited thereto, as long as the slider 31 can be fixed.
Taking the specific example shown in fig. 1 to 5 as an example, the first substrate 20 is provided with at least one accommodating groove 202 for placing a chip, the second substrate 21 is convexly provided with at least one absorption portion 212 for absorbing the chip, and the absorption portion 212 loads or unloads the chip on the accommodating groove 202.
Specifically, the first substrate 20 is a shuttle car for accommodating chips, and the second substrate 21 transports the chips from the accommodating grooves 202 on the first substrate 20 to a test station for chip testing, or the second substrate 21 transports the tested chips back to the accommodating grooves 202 on the first substrate 20. Since the requirement for the accuracy of the chip position is very high during the chip testing process, it is necessary to provide the positioning holes 211 and the positioning shafts 201 on the first substrate 20 and the second substrate 21 for positioning to ensure that the chip does not deviate during the transportation of the second substrate 21. However, the positioning shaft 201 of the first substrate 20 and the positioning hole 211 of the second substrate 21 need to be frequently inserted, so that the positioning shaft 201 and the positioning hole 211 are easily worn and inaccurate in positioning, the hole shaft offset detection fixture 1 of the embodiment of the present invention can accurately measure the offset of the positioning shaft 201 and/or the positioning hole 211, so as to accurately obtain the wear loss, and can prevent the problem of chip testing caused by excessive wear of the positioning shaft 201 and the positioning hole 211. Of course, the hole axis offset detection jig 1 of the embodiment of the present invention is not limited to be applied in the field of chip testing, and other devices that need to be positioned by the positioning hole 211 and the positioning shaft 201 can also measure the offset of the positioning shaft 201 and/or the positioning hole 211 by using the hole axis offset detection jig 1 of the embodiment of the present invention, so the hole axis offset detection jig 1 of the embodiment of the present invention has a simple structure and a wide application range.
The embodiment of the invention also discloses an operation method of the hole axis offset detection jig 1, which comprises the following steps:
the fixing device 30 fixes the first substrate 20 on the base 10;
