Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a separate lifting control device used for thread gauge detection. Background Art

[0002] The threaded holes set on metal die-castings usually need to be tested with a thread gauge. Specifically, the center of the positive threaded hole is tested using a thread gauge. The thread gauge includes a go gauge and a stop gauge. When the go gauge is screwed into the threaded hole, if it can pass through the threaded hole smoothly, it means that the threaded hole has passed the go gauge test. When the stop gauge is screwed into the screw hole, if the stop gauge cannot pass through the screw hole, it means that the threaded hole has passed the stop gauge test.

[0003] However, the detection of thread gauges has other particularities. That is, when the gauge is vertically controlled to descend to the edge of the threaded hole of the die-casting, it is necessary to switch to another mechanism to control the rotation to control the gauge to continue to screw into the threaded hole. Then how to switch the vertical control to the rotation control gauge is a pain point in the industry and needs to be solved urgently. Utility Model Content

[0006] Optionally, the separate lifting control device used for thread gauge detection also includes a support plate and a tension spring, the support frame is fixedly installed on the front side of the support plate, the upper end of the tension spring is connected to the upper end of the support plate, and the lower end of the tension spring is connected to the lower moving block.

[0010] The above one or more technical solutions in the separate lifting control device for thread gauge detection provided by the embodiment of the present invention have at least one of the following technical effects: the support frame serves as the supporting and mounting structure of the entire device, and an upper cantilever block, a middle cantilever block and a lower cantilever block are arranged on the same side. The Z-axis motor drives the Z-axis screw to rotate, and the Z-axis nut threadedly connected to the Z-axis screw is moved downward, thereby driving the upper moving block connected to the Z-axis nut to move downward. During the downward movement of the upper moving block, the upper guide sleeve will press the lower guide sleeve, thereby forcing the lower moving block connected to the lower guide sleeve to move downward, so that the gauge directly or indirectly connected to it can be driven to move downward by the lower moving block; when the downward movement work is completed, when the Z-axis motor starts to reset, it only controls the upper moving block to move upward, and the lower moving block still remains in a lower position to ensure that the gauge it controls is screwed into the threaded hole for detection.

The separate lifting control device of the utility model for thread gauge detection can be applied to thread gauge detection equipment, can control the descent of the gauge directly or indirectly connected thereto, and can avoid driving the gauge upward when resetting, so as to ensure that the gauge continues to rotate in the threaded hole through the drive of other driving components, thereby satisfying the vertical driving of the gauge without affecting the rotation drive of the gauge by other components.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0023] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0024] like Figures 1-2 As shown, the embodiment of the present invention provides a separate lifting control device for thread gauge detection, which includes a support frame 42b, a Z-axis motor 42c, a Z-axis screw rod 42d, a Z-axis nut 42e, an upper moving block 42f, a lower moving block 42a, a guide shaft 42g, an upper guide sleeve 42h and a lower guide sleeve 42i, and an upper cantilever block 42b1, a middle cantilever block 42b2 and a lower cantilever block 42b3 are provided on the support frame 42b, the Z-axis motor 42c is installed on the upper cantilever block 42b1 and is arranged downward, the Z-axis screw rod 42d is driven and connected to the Z-axis motor 42c and passes through the middle cantilever block 42b2 in sequence. After the cantilever block 42b2, the upper moving block 42f and the lower moving block 42a, the bottom end thereof is rotatably connected to the lower cantilever block 42b3, the Z-axis nut 42e is threadedly connected to the Z-axis screw rod 42d and fixed on the upper moving block 42f, the guide shaft 42g is vertically connected between the middle cantilever block 42b2 and the lower cantilever block 42b3, the upper guide sleeve 42h and the lower guide sleeve 42i are both sleeved outside the guide shaft 42g, and the upper guide sleeve 42h is connected and fixed to the upper moving block 42f, and the lower guide sleeve 42i is connected and fixed to the lower moving block 42a.

[0025] Specifically, the support frame 42b serves as the supporting and mounting structure of the entire device, and an upper cantilever block 42b1, a middle cantilever block 42b2 and a lower cantilever block 42b3 are provided on the same side. The Z-axis motor 42c drives the Z-axis screw rod 42d to rotate, and the Z-axis nut 42e threadedly connected to the Z-axis screw rod 42d moves downward, thereby driving the upper moving block 42f connected to the Z-axis nut 42e to move downward. During the downward movement of the upper moving block 42f, the upper guide sleeve 42h will press the lower guide sleeve 42i, thereby forcing the lower moving block 42a connected to the lower guide sleeve 42i to move downward, so that the lower moving block 42a can drive the gauge directly or indirectly connected to it to move downward; when the downward movement work is completed, when the Z-axis motor 42c starts to reset, it only controls the upper moving block 42f to move upward, and the lower moving block 42a still remains in a lower position to ensure that the gauge it controls is screwed into the threaded hole for detection. At this time, it can be switched to another control device to control the rotation of the gauge.

[0026] The separate lifting control device of the utility model for thread gauge detection can be applied to thread gauge detection equipment, can control the descent of the gauge directly or indirectly connected thereto, and can avoid driving the gauge upward when resetting, so as to ensure that the gauge continues to rotate in the threaded hole through the drive of other driving components, thereby satisfying the vertical driving of the gauge without affecting the rotation drive of the gauge by other components.

[0027] In one embodiment of the present invention, the separate lifting control device used for thread gauge detection also includes a support plate (not shown) and a tension spring (not shown), the support frame 42b is fixedly installed on the front side of the support plate, the upper end of the tension spring is connected to the upper end of the support plate, and the lower end of the tension spring is connected to the lower moving block 42a of the lower moving block. Specifically, the lower moving block 42a also stretches the tension spring connected to its bottom end during the downward movement process. Then, when the Z-axis motor 42c starts to reset, it only controls the upper moving block 42f to move up, and the lower moving block 42a still remains in a lower position to ensure that the gauge 45l is screwed into the threaded hole for detection. When the gauge 45l is reversed and screwed out of the threaded hole, the lower moving block 42a is pulled up by the tension spring connected to the top of the support plate, thereby driving the gauge to move up and wait for the next work. This structure cleverly avoids the reset of the Z-axis motor 42c directly driving the rise of the gauge indirectly controlled by it, and ensures that the lowering and screwing-in actions of the gauge are separately controlled.

[0028] In one embodiment of the present invention, two guide shafts 42g, two upper guide sleeves 42h and two lower guide sleeves 42i are provided, the two guide shafts 42g are distributed on both sides of the Z-axis screw rod 42d, the two upper guide sleeves 42h are respectively connected with the two guide shafts 42g and are distributed on both sides of the Z-axis nut 42e, and the two lower guide sleeves 42i are respectively connected with the two guide shafts 42g and are respectively located below the two lower guide sleeves 42i. Specifically, the provision of two guide shafts 42g, two upper guide sleeves 42h and two lower guide sleeves 42i can ensure the vertical movement of the upper moving block 42f and the lower moving block 42a accurately, and can more stably support the upper moving block 42f and the lower moving block 42a, so as to carry and drive the tooth gauge and its adapted components directly or indirectly connected to the lower moving block 42a.

[0029] In one embodiment of the present invention, a connecting portion 42a1 extends from the end of the lower movable block 42a, and an axial sleeve hole 42a2 is provided on the connecting portion 42a1. Specifically, the connection portion 42a1 provides a larger space for installation and connection with the lower movable block 42a. Furthermore, the vertically arranged axial sleeve hole 42a2 provided on the connecting portion 42a1 is used to pass the shaft of the connecting gauge, thereby facilitating the connection and installation of the gauge with the device.

[0030] In one embodiment of the present invention, the top edge of the axial sleeve hole forms an inner chamfered surface 42a3. Specifically, the configuration of the inner chamfered surface 42a3 allows the axial sleeve hole 42a2 to form a tapered hole. The recessed portion of the inner chamfered surface 42a3 can then accommodate a bearing or a sleeve, or a flange structure on the bearing / sleeve. This allows the lower movable block 42a to abut against the bearing or sleeve. When the lower movable block 42a moves upward, it can drive the bearing or sleeve upward, thereby driving the thread gauge connected to the bearing or sleeve upward. This structural design is ingenious and highly practical.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
