[0002] For parts formed by hot pressing, the material needs to be heated during the hot pressing process. After the forming is completed, the product is taken out of the mold and cooled. During the cooling process, the material will shrink. Due to the differences in the raw materials themselves, there are differences in the shrinkage rate, which will lead to differences in the final part size. If the material shrinkage rate is too large or too small, the product size will be unqualified. Therefore, during production, it is necessary to conduct quality inspections on the product size.

[0021] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0022] Example:

[0023] like Figure 1-Figure 2 As shown, a part detection device includes a detection platform 1, the detection platform 1 is provided with a detection area matching the contour of the part to be detected, the part to be detected is arranged in the detection area, the positioning device 2, the calliper 3 and the controller, the positioning device 2 and the calliper 3 are arranged at the edge of the detection area, the positioning device 2 is attached to the part to be detected, the calliper 3 is provided with a plurality of distance measuring modules, a group of parts to be detected corresponds to a group of distance measuring modules, the straight-line distance between the parts to be detected and the distance measuring modules is detected, and the distance measuring modules are connected to the controller for communication to form a transmission of detection data.

[0024] For the convenience of explanation, a plane coordinate system is established, such as Figure 1 As shown, in this embodiment, the direction indicated by the ox axis is set as the length direction of the detection platform 1, that is, the detection area, and the direction indicated by the oy axis is set as the width direction of the detection platform 1, that is, the detection area.

[0025] In this embodiment, the detection platform 1 is installed on a base 4 .

[0026] The positioning device 2 includes a plurality of positioning rods 21, which are fixed on the detection platform 1 and distributed circumferentially at the edge of the detection area. The positioning rods 21 serve as positioning structures for positioning the parts to be detected when they are placed in the detection area. Specifically, the parts to be detected are placed in the detection area and are positioned against the positioning rods 21.

[0027] A plurality of positioning rods 21 are distributed in the width direction and the length direction of one side of the detection area to expand the positioning range of the positioning rods 21 on the parts to be detected and improve the stability of the positioning of the parts to be detected.

[0028] In this embodiment, there are four groups of positioning rods 21 , two groups of positioning rods 21 are distributed in the width direction of the detection area, and the other two groups of positioning rods 21 are distributed in the length direction of the detection area.

[0029] The caliper 3 is arranged in the width direction of the detection platform 1. The caliper 3 and the positioning rod 21 are respectively located in the width direction of both sides of the detection area, so the distance measuring module is used to detect the linear distance between it and the part to be detected in the length direction.

[0030] The reason why the caliper 3 in this embodiment is arranged in the width direction of the detection platform 1 and the distance measuring module detects the straight-line distance between it and the part to be detected in the length direction is that: for parts formed by hot pressing process, the material needs to be heated during the hot pressing process. After the forming is completed, the product is taken out of the mold for cooling. During the cooling process, the material will shrink. Generally speaking, the degree of shrinkage in the length direction of the part is greater than the degree of shrinkage in the width direction. Therefore, the current product determines whether the product is qualified by detecting the degree of shrinkage in the length direction of the part. Based on this, the caliper 3 in this embodiment is arranged in the width direction of the detection platform 1 and the distance measuring module detects the straight-line distance between it and the part to be detected in the length direction.

[0031] The caliper 3 includes a mounting rod 31 and a holder 32. The holder 32 is fixed on the detection platform 1. The mounting rod 31 and the holder 32 are connected. A plurality of distance measuring modules are installed on the side of the mounting rod 31 facing the part to be detected along the length direction of the mounting rod 31.

[0032] Specifically, the mounting rod 31 is provided with a mounting groove, and a plurality of ranging modules are arranged in the mounting groove. The mounting height of the ranging modules matches the placement height of the parts to be detected. A group of ranging modules is used to detect the straight-line distance between them and a group of parts to be detected. Therefore, a plurality of ranging modules can detect a plurality of parts to be detected at the same time, thereby realizing the inspection of a plurality of parts to be detected at one time, and effectively improving the detection efficiency.

[0033] Preferably, the distance measuring module can be slidably installed in the installation groove to achieve the measurement of parts to be inspected with different thicknesses.

[0034] The distance measuring module includes at least one of an infrared distance measuring device, a laser distance measuring device, an ultrasonic distance measuring device and a radar distance measuring device.

[0035] In order to adapt to the detection of products of different lengths or to facilitate the adjustment of the installation position of the mounting rod 31, the mounting rod 31 of this embodiment is telescopically connected to the socket 32. Specifically, the socket 32 ​​is provided with a connecting rod 34, and the connecting rod 34 is provided with a plurality of connecting holes. The mounting rod 31 is provided with a mounting hole, and the mounting hole is opposite to any connecting hole. The mounting rod 31 and the connecting rod 34 are connected by pin holes, thereby realizing the telescopic connection between the mounting rod 31 and the socket 32.

[0036] The mounting rod 31 has a working position and a retracted position. The working position and the retracted position are set positions. When the mounting rod 31 is in the working position, the distance between the ranging module and the contour of the detection area is a set value; when the mounting rod 31 is in the retracted position, the mounting rod 31 retracts to a position away from the detection area to prevent the mounting rod 31 from interfering with the parts to be detected when they are placed in the detection area.

[0037] The mounting rod 31 realizes the conversion between the working position and the retreat position through the cylinder 33. Specifically, the clamping seat 32 is fixed with the cylinder 33, and the output shaft of the cylinder 33 is connected to the mounting rod 31 or the connecting rod 34. The conversion between the working position and the retreat position of the mounting rod 31 is realized through the action of the cylinder 33.

[0038] The controller has a preset value for the straight-line distance between the built-in distance measuring module and the part to be inspected, and the preset value range is set to 2mm-8mm. The controller uses a conventional computer, and the computer performs conventional data comparison on the received inspection data. If the inspection data is not within the preset value range, the product size is unqualified. If the received inspection data is less than 2mm, it means that the size of the part to be inspected is too large. If the received inspection data is greater than 8mm, it means that the size of the part to be inspected has shrunk too much during the hot pressing process, resulting in the size of the part to be inspected being too small.

[0039] The parts detection device also includes an alarm device, which communicates with the controller. The controller sends an electrical signal to the alarm device for alarm or prompting. When the detection data is not within the preset value range, the controller sends an electrical signal of unqualified size to the alarm device for alarm. When the detection data is within the preset value range, the controller sends an electrical signal of qualified size to the alarm device for prompting.

[0040] The alarm device includes at least one of an indicator light, a buzzer and an audible and visual alarm. In this embodiment, the alarm device is an indicator light, and the indicator light has a qualified indication color and an alarm indication color. When the indicator light is the qualified indication color, it means that the product size is qualified. When the indicator light is the alarm indication color, it means that the product size is unqualified. By setting the indicator light as an alarm device, the color of the indicator light can be seen to quickly determine whether the size of the current part to be inspected is qualified.

[0041] The parts inspection device also includes a rotating structure, which is arranged between the inspection platform 1 and the base 4, so that the inspection platform 1 can rotate relative to the base 4. The present application sets the inspection platform 1 to be rotatable, which is convenient for the operator to trim the burrs. The operator only needs to stand in a fixed position and rotate the inspection platform 1 to complete the burr trimming and inspection of the entire product, which greatly improves the efficiency of product burr trimming and inspection.

[0042] The rotating structure can be set as a rotating bearing, through which the detection platform 1 can be manually rotated relative to the base 4, or the rotating structure can be set as a rotating motor, which is fixed to the base 4, and the output shaft of the rotating motor is fixedly connected to the detection platform 1, so that the detection platform 1 can be automatically rotated relative to the base 4 through the rotating motor.

[0043] The implementation process of the parts detection device is as follows: during detection, the mounting rod 31 retreats to a retreat position away from the detection area, the part to be detected is placed in the detection area and the part to be detected is positioned against the positioning rod 21, and when the mounting rod 31 is moved to the working position, the distance measuring module detects the straight-line distance between it and the part to be detected, and the distance measuring module transmits the detection data to the controller, and the controller compares the detection data with the preset value. If the detection data is not within the preset value range, the controller sends an electrical signal of unqualified size to the alarm device for alarm; if the detection data is within the preset value range, the controller sends an electrical signal of qualified size to the alarm device for prompting, and the detection platform 1 is rotated after detection, and the operator completes the burr trimming and inspection of the entire product.

[0044] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
