Description

Technical Field

[0001] The utility model relates to the field of detection equipment design, in particular to a detection equipment for the surface of a metal shell with a cavity. Background Art

[0002] After processing, many products require surface dimensional testing using inspection equipment to determine whether the product meets the required accuracy. Housings, as a common product, naturally also require surface testing.

[0003] Most of the existing shell detection equipment is contact detection equipment, and in order to adapt to shell detection at different heights, the detection part of the detection equipment is mostly movable, which relies on power devices such as cylinders to move the detection part of the detection equipment until the detection equipment and the shell are in contact to achieve detection.

[0004] Many shells have cavities that can be used to accommodate other parts. When inspecting metal shells with cavities, in order to reduce deformation of the shell during inspection and reduce displacement of the shell during inspection, supports are often required in the shell cavity. However, the cavity sizes of different shells vary. Frequent replacement of cavity supports during inspection is time-consuming and labor-intensive, and has poor flexibility.

[0005] On the other hand, when the detection part and the shell of the existing detection equipment come into contact, the impact is relatively large, which easily causes deformation of the shell or the detection part. Utility Model Content

[0006] The purpose of the present utility model is to provide a detection device for the surface of a metal shell with a cavity, which can solve one or more of the above problems.

[0007] According to one aspect of the present invention, a device for detecting the surface of a metal shell with a cavity is provided, comprising a detection mechanism, a lifting mechanism, a lifting platform, a buffer mechanism, a detection platform and a shell seat.

[0008] The lifting mechanism is connected to the detection platform, the lifting platform is connected to the lifting mechanism, the detection mechanism is connected to the lifting platform, and the buffer mechanism is connected to the detection platform and is arranged below the lifting platform.

[0009] The housing seat includes a clamping column, a base, a support column and a spring. The clamping column and the base are both connected to the detection table. The base is provided with a through hole.

[0010] One end of the support column is provided with a protrusion, and the other end can be movably extended into the through hole. The spring is sleeved on the support column, one end of the spring is connected to the protrusion, and the other end is connected to the detection platform. The support column is arranged below the detection mechanism.

[0011] The beneficial effects of the present invention are as follows: in the present invention, the cavity metal shell can be clamped on the clamping column, so that the above-mentioned cavity metal shell can be effectively fixed on the shell seat, and the support column can be against the inside of the cavity of the shell to support the part of the cavity metal shell to be detected. Since the spring has an elastic effect, the support column can match the use of different cavity heights and sizes, and has strong flexibility. During detection, the lifting platform can be driven down by the lifting mechanism, so that the detection mechanism can contact the surface of the cavity metal shell on the shell seat to detect its surface, and since a buffer mechanism is provided, the buffer mechanism can buffer the impact of the lifting platform when the lifting platform moves down into place, thereby avoiding excessive impact of the detection mechanism on the cavity metal shell, so as to reduce the probability of deformation of the shell or the detection mechanism.

[0012] In some embodiments, the detection mechanism includes a detector, a connecting plate, and a connecting rod. Multiple connecting rods are provided, each connected at one end to the lifting platform and at the other end to the connecting plate. The detector is mounted on the connecting plate and positioned opposite the support column. By replacing connecting rods of different lengths, the height of the detector can be easily adjusted to suit different detection needs.

[0013] In some embodiments, the buffer mechanism includes a first buffer and a first buffer seat, wherein the first buffer seat is connected to the test platform and the first buffer is mounted on the first buffer seat. By providing the first buffer seat, the installation height of the first buffer can be easily adjusted by adjusting the installation position of the first buffer.

[0014] In some embodiments, the lifting mechanism includes a bracket, a guide rail, a slider, and a cylinder. The bracket is connected to the inspection platform, the guide rail is mounted on the bracket, the slider is slidably mounted on the guide rail, the lifting platform is connected to the slider, and the cylinder is mounted on the bracket and connected to the lifting platform. The cylinder can drive the lifting platform to move, and the movement of the lifting platform can cause the slider to slide along the guide rail, thereby reducing offset caused by the lifting platform's movement other than lifting.

[0015] In some embodiments, the device includes a stopper, a second buffer, and a second buffer seat. The second buffer seat is connected to the bracket, and the second buffer is mounted on the second buffer seat. The stopper is connected to the lifting platform, and the second buffer is located above the stopper. After the lifting platform is raised to its position, the second buffer can provide cushioning, thereby reducing the impact of the lifting platform on other structures due to the lifting movement.

[0016] In some embodiments, the detection station is provided with a controller and a display, the detection mechanism is electrically connected to the controller, and the controller is electrically connected to the display. The detection results obtained by the detection mechanism can be displayed on the display.

[0017] In some embodiments, the present invention further comprises a power device, wherein the test platform is provided with a start button, the power device is mounted on the test platform and connected to the lifting mechanism, and the power device and the start button are electrically connected to a controller. The start button can be triggered to activate the power device, thereby driving the lifting mechanism to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The detection mechanism 1 includes a detector 11, a connecting plate 12, and a connecting rod 13. There can be multiple connecting rods 13. In this embodiment, four connecting rods 13 are preferably used.

[0030] The housing base 6 includes a clamping column 61, a base 62, a support column 63, and a spring 64. The clamping column 61 is fixedly connected to the detection platform 5 by screws, and the base 62 is also fixedly connected to the top surface of the detection platform 5 by screws. The base 62 is provided with a through hole 621. The top of the support column 63 is provided with a protrusion 631, and the bottom end of the support column 63 extends into the through hole 621 and can move along the through hole 621. The spring 64 is sleeved on the support column 63, and one end of the spring 64 abuts against the bottom of the protrusion 631, and the other end of the spring 64 abuts against the top surface of the detection platform 1. After being set, the support column 63 is opposite to the detector 11 and is located below the detector 11.

[0031] The present cavity metal shell surface inspection device further includes a stopper 7, a second buffer 8, and a second buffer seat 9.

The stopper 7 is fixedly connected to the lifting platform 3 by screws, and the second buffer 8 is arranged above the stopper 7, so that when the lifting platform 3 rises to a certain position, the stopper 7 connected to the lifting platform 3 can contact the second buffer 8.

[0032] A controller is provided in the detection platform 5, which can preferably be a single-chip microcomputer, and a display 51 is provided on the detection platform 5. The detector 11 of the detection mechanism 1 can be electrically connected to the controller through a wire, and the controller can be electrically connected to the display 51 through a wire, so that the results detected by the detector 11 can be transmitted to the controller and displayed through the display 51.

[0033] The present cavity metal shell surface inspection device further includes a power device 10. The power device 10 can preferably be an electric air pump, which is fixedly mounted on the inspection platform 5 by screws, and the air pump on the electric air pump can be connected to the cylinder 24 of the lifting mechanism 2 via a pipe.

[0034] When the detection device for the surface of the cavity metal shell is in use, the cavity metal shell 20 can be clamped on the clamping column 61, and the cavity metal shell 20 can be set on the support column 63, then the support column 63 can be set in the cavity of the cavity metal shell 20, and at the same time, relying on the action of the spring 64, the support column 63 can support the top wall of the cavity of the cavity metal shell 20 to effectively support the shell 20.

[0035] The power device 10 can be connected to an external air source, and then the start button 52 can be pressed so that the external air source can supply air to the cylinder 24 through the power device 10, and the cylinder 24 can drive the lifting platform 3 to move downward, and the downward movement of the lifting platform 3 can move the slider 23 along the guide rail 22 to reduce the unexpected position offset of the lifting platform 3 during movement. As the lifting platform 3 moves downward, the detector 11 also moves downward. When the lifting platform 3 moves down to its position, the cylinder 24 stops working, and the lifting platform 3 stops moving accordingly. The lifting platform 3 can abut against the first buffer 41, so that the first buffer 41 can cushion the impact of the lifting platform 3 caused by inertia. At the same time, the detector 11 can contact the surface of the cavity metal shell 20 to detect the surface of the cavity metal shell 20.

[0036] The results obtained from the test can be displayed on the display 51. After the test is completed, the cylinder 24 can work again to drive the lifting platform 3 to move upward. The upward movement of the lifting platform 3 can also move the slider 23 along the guide rail 22 to reduce the unexpected position deviation of the lifting platform 3 during movement. When the lifting platform 3 moves up to the initial position, the cylinder 24 stops working and waits for the next test. When the lifting platform 3 rises to its position, the abutment 7 connected to the lifting platform 3 can abut against the second buffer 8, so that the second buffer 8 can cushion the impact of the lifting platform 3 caused by inertia.

[0037] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
