Description

Technical Field

[0001] This utility model relates to the field of casting inspection technology, and in particular to a part hole feature inspection station. Background Technology

[0002] In aluminum alloy parts machining, special dimensional characteristics (such as hole diameter, roundness, and dimensional accuracy) are easily affected by process fluctuations, requiring full-process inspection for quality control. Current inspection procedures require operators to transfer the workpiece to the inspection table, manually hold the product in place, and simultaneously operate a pneumatic measuring instrument, repeatedly flipping the workpiece to complete multi-directional dimensional measurements and data recording. Because the inspection table lacks positioning aids, operators must simultaneously support the workpiece with one hand while operating the instrument, resulting in poor coordination and insufficient posture stability. This not only increases labor intensity but also affects measurement efficiency and result consistency, making it difficult to meet the demands of high-precision, high-frequency inspections.

Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figure 1 A part hole feature inspection station according to an embodiment of the present invention includes a machine base 100, which includes a worktable 110 and a fixture frame 130. The worktable 110 is provided with a slidably connected platform 111, which can move along the length direction of the worktable 110. The fixture frame 130 is installed on one side of the worktable 110 along the width direction, and a plurality of pneumatic probes 136 are arranged at intervals along the length direction on the fixture frame 130. During the inspection process, the position of the workpiece can be adjusted by moving the platform 111, which facilitates the use of different pneumatic probes 136 to inspect the hole features of the workpiece and improves the flexibility of the inspection.

[0032] Specifically, refer to Figure 4The worktable 110 is provided with two guide rails 101 arranged side by side along the width direction. The platform 111 includes a slide plate 112 and a carrier plate 113. The bottom of the slide plate 112 is provided with a plurality of sliders 114 slidably connected to the guide rails 101. The carrier plate 113 is used to load workpieces and is pivotally connected to the slide plate 112. In this embodiment, both the carrier plate 113 and the slide plate 112 are disc-shaped. Further, the carrier plate 113 is provided with a first brake 115, which is used to prevent the carrier plate 113 from moving relative to the slide plate 112; at the same time, the slide plate 112 is provided with a second brake 118, which is used to prevent the slide plate 112 from moving, so that when the platform 111 places a workpiece, the workpiece can be prevented from moving or rotating due to accidental collision, which is beneficial to improving safety.

[0033] Understandably, the first brake 115 includes a first switch 116 and a first brake block 117, with the first switch 116 pivotally connected to the outer periphery of the carrier plate 113. Further, the first switch 116 includes a gripping portion 1161 and a stop portion 1162 fixedly connected. The gripping portion 1161 extends radially outward along the carrier plate 113, and the stop portion 1162 extends downward perpendicular to the extending direction of the gripping portion 1161. Understandably, the first brake block 117 is mounted on the stop portion 1162, and the first brake block 117 abuts against the outer peripheral wall of the slide plate 112. The first brake block 117 is made of materials such as rubber or polyurethane to achieve the braking function of the carrier plate 113. Further, a torsion spring (not shown in the figure) is provided at the pivotal connection between the gripping portion 1161 and the carrier plate 113. The torsion spring enables the first switch 116 to have a rotational tendency, thereby keeping the first brake block 117 in contact with the outer peripheral wall of the slide plate 112. When the grip 1161 is pulled up, the stop 1162 rotates, causing the first brake block 117 to disengage from the slide plate 112, allowing the carrier plate 113 to rotate relative to the slide plate 112. Understandably, using the method of pulling up the grip 1161 to release the brake avoids accidental activation of the first switch 116 during testing, preventing sudden movement of the carrier plate 113 and ensuring braking stability.

[0034] Furthermore, the second brake 118 includes a second switch 119 and a second brake block 120. The second brake 118 is located on the bottom wall of the slide plate 112 away from the carrier plate 113. Specifically, the second switch 119 has a pressure contact portion 1191 embedded in the slide plate 112, and the second brake block 120 is mounted on the other end of the second switch 119 away from the pressure contact portion 1191. It is understood that the guide rail 101 has a base plate 1011 for connection to the surface of the worktable 110. It is understood that a spring is present between the slide plate 112 and the pressure contact portion 1191, and the spring can cause the pressure contact portion 1191 to tend to protrude towards the bottom of the slide plate 112, thereby enabling the second brake block 120 to maintain pressure on the base plate 1011 to achieve the braking function of the slide plate 112. Understandably, the second switch 119 is located at the bottom of the slide plate 112, and the brake is released by pulling up the pressure contact 1191. This can prevent the slide plate 112 from moving suddenly due to accidental activation of the second switch 119 during the detection process, which helps to ensure the stability of the brake.

[0035] Reference Figure 2 It is understood that the fixture frame 130 is provided with a support plate 131, and the support plate 131 has multiple compartments 132, which are used to install pneumatic probes 136 of different specifications. Specifically, the pneumatic probe 136 includes a rod 138 and a detection part 139. The detection part 139 is installed at the end of the rod 138. The other end of the rod 138 away from the detection part 139 is provided with a mounting plate 137. The mounting plate 137 extends radially outward along the rod 138, such that the minimum outer diameter of the mounting plate 137 is greater than the maximum outer diameter of the rod 138. At the same time, the compartment 132 includes a mounting groove 134 and a through groove 135. The mounting groove 134 and the through groove 135 are connected. The mounting groove 134 is located above the through groove 135, and the through groove 135 has a U-shaped cross-section. When the pneumatic probe 136 is inserted into the compartment 132, the rod 138 is located in the through groove 135, and the mounting plate 137 is embedded in the mounting slot 134. Furthermore, the maximum inner diameter of the through groove 135 is smaller than the minimum inner diameter of the mounting slot 134, preventing the pneumatic probe 136 from slipping out of the mounting slot 134. To remove the pneumatic probe 136, it is necessary to lift the pneumatic probe 136 and move the mounting plate 137 away from the mounting slot 134 so that the rod 138 can move horizontally away from the fixture frame 130 and disengage from the through groove 135, thus completing the inspection process. To reposition the pneumatic probe 136 into the compartment 132, the rod 138 must first be embedded in the through groove 135, and then the pneumatic probe 136 must be lowered, with the mounting plate 137 embedded in the mounting slot 134. This ensures that the pneumatic probe 136 is stably placed on the support plate 131, making the operation simple and the positioning secure.

[0036] Reference Figure 1The fixture rack 130 has pivotally connected placement boxes 140 on both sides along its length. The placement box 140 has a first receiving plate 141 capable of accommodating the calibration gauge. A hinge is provided between the placement box 140 and the fixture rack 130, which allows the position of the placement box 140 to be adjusted in actual use. This improves the storage capacity of the machine tool 100 and facilitates flexible use, while preventing the placement box 140 from interfering with other equipment.

[0037] Furthermore, the worktable 110 is provided with pivotally connected second receiving plates 102 on both sides along its length. The second receiving plates 102 are used to hold various calibration gauges of different specifications. At the same time, a third receiving plate 103 is provided on either side of the worktable 110 along its length. The third receiving plate 103 is located on one side of the guide rail 101 and can hold electronic plug gauges 105. By setting up the first receiving plate 141, the second receiving plate 102, and the third receiving plate 103 to hold various different testing instruments, the adaptability to different types of workpieces can be improved, thereby increasing the flexibility of use.

[0038] Reference Figure 3 The bottom wall of the support plate 131 is provided with multiple connecting plates 142. The connecting plates 142 are U-shaped and wrap around the outer periphery of the through groove 135. Sensors 133 are provided on the connecting plates 142, and the sensors 133 are provided on at least one side of the rod 138. It can be understood that the sensors 133 can detect whether the rod 138 is located in the through groove 135, thereby detecting whether the pneumatic probe 136 is placed on the support plate 131.

[0039] It is understood that the system also includes a detection system, which comprises a controller, a pneumatic probe 136, and an indicator light 104. The controller is electrically connected to the pneumatic probe 136 and the sensor 133. It is also understood that the indicator light 104 is mounted on the fixture frame 130. In this embodiment, the pneumatic probe 136 is a pneumatic internal diameter detector. The detection section 139 of the pneumatic probe 136 has an air outlet, which is connected to compressed air through an air inlet. During measurement, the pneumatic probe 136 is located inside the workpiece being measured, with the air outlet close to the measurement point of the workpiece. There is a gap between the probe and the workpiece, and compressed air escapes from this gap. Changes in the size of the gap will cause changes in the pressure of the incoming air. The pneumatic-electric converter converts this pressure change into a relevant electrical signal and sends it to the controller. The controller can then provide feedback on the detection result through the indicator light 104. For example, if the indicator light 104 displays green light, it indicates that the detected hole feature is qualified; if the indicator light 104 displays red light, it indicates that the detected hole feature is unqualified. This intuitive display helps improve detection efficiency. Furthermore, a display screen (not shown in the figure) is installed on the inspection fixture 130. The display screen can show the operating information of the inspection system, which is convenient for workers to view directly.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
