Mounting base 7 is adsorbed on external equipment by the first strong magnets 73 in which can be convenient.
In the present invention, in specific implementation, the clearance measurement auxiliary mould 5 includes the measuring block of vertical distribution
51, multiple second strong magnets 52 (being not limited to two shown in Fig. 7) are embedded on the measuring block 51；
The side of the measuring block 51 is adsorbed on the to be checked of the cavity plate cavity 40 for needing to detect by the second strong magnets 52
Survey side wall.
In specific implementation, the side (including leading flank and trailing flank) of the measuring block 51 is plane, to guarantee gap
Measure the surface planarity of auxiliary mould 5.
It should be noted that for the utility model, the clearance measurement auxiliary mould 5 having can be by embedded
Second strong magnets 52 are adsorbed on the side wall to be detected of cavity plate cavity 40, thus by due to the space of cavity plate cavity 40 it is limited, and
The side wall to be detected (i.e. undetectable face, can not directly detect) for being inconvenient to the cavity plate cavity measured is converted to and is easy measurement
The detection faces (i.e. the side of measuring block 51) of clearance measurement auxiliary mould 5, i.e., be converted to shell detection faces for undetectable face, so
Afterwards, by laser displacement sensor 6, to measure detection faces (the i.e. measuring block that laser displacement sensor 6 arrives 5 tooling of subsidiary
51 side) the distance between L1.
Referring to shown in Fig. 1, Fig. 2, when the front for rushing shell mold tool is arranged in laser displacement sensor 6, although cavity plate cavity
40 front side wall can not be detected directly, by clearance measurement auxiliary mould 5, can detecte laser displacement sensor 6 to matrix cavity
The distance between 40 front side wall of body.
Due to being provided with measured hole 41 on the cavity plate 4 of the utility model, by measured hole 41, laser displacement can be allowed
The detection of sensor 6 laser light cavity plate 4 is in contact with the side wall to be detected of punch-pin 2 being located in cavity plate cavity 40, thus
Guarantee measurement at concave-convex mold molding (i.e. punch-pin 2 is inserted into cavity plate cavity 40), laser displacement sensor 6 is to be checked to punch-pin 2
Survey the distance between side wall L2.It should be noted that between distance L1 and L2 difference absolute value, as rush shell mold tool in bumps
The clearance between punch and die value that mould has when molding.
Referring to shown in Fig. 3, Fig. 4, when laser displacement sensor 6 is mounted on the front for rushing shell mold tool, laser position can detecte
Displacement sensor 6 arrives the distance between the front side wall of cavity plate cavity 40.
In order to which the technical solution of the utility model is more clearly understood, below with regard to the specific operation process of the utility model
It is illustrated.
Referring to FIG. 1 to FIG. 4, firstly, laser displacement sensor 6 is mounted in the linear guide 72 of mounting base 7, so
Afterwards, mounting base 7 is adsorbed on external equipment (such as metallic operation platform) by the first strong magnets 73.Laser displacement sensor
The power supply of 6 connection 24V, separates a certain distance with pressure plate 3 for cavity plate 4, gap subsidiary tooling 5 is adsorbed on matrix cavity
On the side wall to be detected (i.e. front side wall) of body 40, the front side wall of cavity plate cavity 40 is converted to the inspection of gap subsidiary tooling 5
Survey face (i.e. the leading flank of measuring block 51) guarantees that the detection faces of gap subsidiary tooling 5 just block the measurement on cavity plate 4
The detection laser in hole 41, laser displacement sensor 6 can pass through the measured hole 41 on cavity plate 4, to detect clearance measurement backman
5 detection faces are filled, detection obtains laser displacement sensor to the spacing for the detection faces for measuring tooling 5, guarantees measured value in laser
In the measuring range of displacement sensor.
Then, laser displacement sensor can be moved along the direction of linear guide, it is auxiliary guarantees that the measuring point of laser gets to gap
It helps in the detection faces of measurement tooling 5, successively measures distance value three times, guarantee that measurement result difference, can within 0.05mm three times
The detection faces (i.e. the leading flank of measuring block 51) of the laser and gap subsidiary tooling 5 that guarantee laser displacement sensor transmitting are hung down
Directly, the vertical range that distance arrives face for point is measured, sensor is zeroed at this time.
Then, gap subsidiary tooling 5 is taken away, cavity plate 4 and punch-pin 2 is subjected to closed procedure, allow punch-pin 2 is past to move down
It is dynamic, it is inserted into cavity plate cavity 40, until laser measuring point can detecte the leading flank of punch-pin 2, at this point, stop mobile punch-pin 2,
According to the spacing of the detection faces of laser displacement sensor to measurement tooling 5 and laser displacement sensor to convex on controller 8
The clearance between punch and die value of corresponding position can be calculated and be shown in the spacing of the leading flank of mould 2.
2 side walls to be detected of cavity plate cavity 40 are replaced, aforesaid operations process is repeated, it can be by remaining of cavity plate cavity 40
It is detected in gap between three faces and punch-pin 2.
It should be noted that the utility model uses non-contact detection, measurement process does not generate the concave-convex mold of mold
Any influence, measurement accuracy are higher.By means of the gap subsidiary tooling specially designed, may be implemented quick and high-precision
Detection.Because of laser sensor and mold separation, same set of measuring device can be with off-line measurement multiple devices.Measurement data can be real-time
Display feedback is carried out by controller, it is more convenient to obtain result.The utility model passes through the thought of conversion, auxiliary by means of gap
Measurement tooling is helped, the matrix cavity body side surface that will be unable to directly detect is converted to the gap subsidiary tooling that can be directly detected
Surface.
Compared with prior art, the utility model is for rushing during shell, because clearance between punch and die it is unqualified caused by shell
Body corner shell shake and pinprick and other issues give battery bring security risk, are detected by high-precision laser displacement sensor
The clearance between punch and die value of clearance between punch and die, the shell mold that liquidates tool is monitored, and guarantees that the concave-convex mold for rushing shell mold tool is mounted in equipment
The Uniform Tension of shell four corners when there is qualified gap width afterwards, and guaranteeing to rush shell, eliminate finally rush hull shape at aluminium
The corner pinprick of mold shell and the generation of corner shell shake guarantee the security performance of battery, reduce because of leakage bulging bring visitor
It tells problem, improves customers' approval degree.
Therefore, in conclusion the utility model, which provides a kind of battery battery core provided by the utility model, rushes shell mold tool
The detection device of clearance between punch and die can accurately and reliably measure the clearance between punch and die for rushing shell mold tool, it is ensured that clearance between punch and die
Meet preset technique requirement, to avoid leading to the plastic-aluminum putamina gone out because the clearance between punch and die for rushing shell mold tool is unqualified
It is bad and other issues that corner pinprick, corner shell shake occurs in body, is conducive to promote and apply, be of great practical significance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
