Description

Technical Field

[0001] The utility model relates to the technical field of mechanical part detection, in particular to a detection device for the internal flower keyboard of a dobby loom. Background Technique

[0002] The dobby mechanism is one of the loom shedding components that convert the fabric pattern signal into a shedding action and drive the heddle frame of the loom to perform the up-and-down shedding movement. After the internal flower keyboard or flower keyboard, which is a dobby mechanism accessory, is precision turned on a lathe, the flower keyboard enters the processes of broaching the spline and pressing the gasket. The spline hole will affect the fitting degree between the flower keyboard and the main shaft, and the gasket hole will affect whether the gasket is riveted in place, thereby affecting the end face runout and radial runout of the flower keyboard. Therefore, it is necessary to measure the diameters of the spline hole and gasket hole of the flower keyboard.

[0003] The existing patent CN219914268U, a detection device for the aperture of an automotive air-conditioning flower keyboard, under the action of the elastic force of the second spring, four clamping blocks can stably clamp the flower keyboard. The hydraulic cylinder pushes the mounting plate to move in the vertical direction. Through the transmission of the mounting plate, the detection component also moves accordingly. During the downward movement of the lower detection component, the detection rod is inserted into the cavity in the middle of the broached spline and the pressed gasket. If the detection rod can pass through the gasket hole and cannot pass through the spline hole, it is considered that the diameter of the gasket hole is within the process requirements; if the measuring tool cannot pass through the gasket hole or passes through both the gasket hole and the spline hole at the same time, the measured flower keyboard needs to be repaired or scrapped. This detection device has a simple structure, is easy to operate, has a good positioning effect, can quickly detect the aperture of the gasket of the flower keyboard, and effectively improves the detection efficiency of the air-conditioning flower keyboard.

[0004] However, during the use of the existing patent, a detection device for the aperture of an automotive air-conditioning flower keyboard, when the device actually positions the flower keyboard, it is necessary to first push the four clamping blocks into the limiting grooves respectively and manually hold the positions of the clamping blocks, and then the flower keyboard can be placed into the fixing ring. This process is difficult to achieve by a single person, making the fixing of the flower keyboard by the device rather troublesome. Content of the Utility Model

[0005] The purpose of the utility model is to provide a detection device for the internal flower keyboard of a dobby loom, which solves the problem that when the aforementioned device actually positions the flower keyboard, it is necessary to first push the four clamping blocks into the limiting grooves respectively and manually hold the positions of the clamping blocks, and then the flower keyboard can be placed into the fixing ring. This process is difficult to achieve by a single person, making the fixing of the flower keyboard by the device rather troublesome.

[0006] To achieve the above object, the utility model provides a detection device for the internal flower keyboard of a dobby loom, which includes a detection table, a positioning ring, a positioning disk and a hole diameter detection device.

[0011] A detection device for the inner flower keyboard of a dobby loom according to the present utility model. When in use, first pull the pull rod towards the outer side of the positioning ring, so that the pull rod drives the sliding clamping block to move along the sliding groove, causing the sliding clamping block to compress the telescopic spring. At the same time, through the rotational cooperation between the connecting column and the rotating disks, the limiting block on the pull rod is driven to rotate, aligning the limiting block with the through groove. Then continue to pull the pull rod, so that the limiting block passes through the through groove. Subsequently, rotate the limiting block again through the pull rod, causing the limiting block to be stuck outside the positioning ring. Then place the flower keyboard into the positioning ring.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0019] The first embodiment of this application is as follows:

[0020] Please refer to Figures 1-3 , Figure 1 which is a schematic diagram of the overall structure of a multi-arm machine internal flower keyboard detection device according to the first embodiment of the present utility model, Figure 2 which is a schematic diagram of the positioning device according to the first embodiment of the present utility model, Figure 3 which is a connection diagram of the pull rod and the connecting column according to the first embodiment of the present utility model.

[0021] The present utility model provides a multi-arm machine internal flower keyboard detection device: including a detection table 101, a positioning ring 102, a positioning disk 103 and a hole diameter detection device, and further including a positioning device. The positioning device includes a telescopic spring 104, a sliding clamping block 105, a limiting block 106, a pull rod 107, a rotating connection assembly and a buffer assembly. The rotating connection assembly includes a connecting column 110 and a rotating disk 111. The buffer assembly includes a fixed disk 113 and a buffer spring 114. By the foregoing solution, the problem that when the foregoing device actually positions the flower keyboard, it is necessary to first push the four clamping blocks into the limiting grooves respectively and manually hold the positions of the clamping blocks, and then the flower keyboard can be placed into the fixed ring, and this process is difficult to achieve by a single person, resulting in a more troublesome fixation of the flower keyboard by the device is solved. The foregoing solution can be used in the scenario of positioning the flower keyboard in the multi-arm machine flower keyboard detection, and can also be used to solve the problems of detecting the inner diameters of the gasket holes and spline holes of the flower keyboard.

[0022] In this embodiment, through multiple rotations of the limiting block 106, the limiting block 106 can be stuck on the outer side of the positioning ring 102, avoiding the need to manually hold the position of the sliding clamping block 105 when positioning the flower keyboard, and thus making the fixation of the flower keyboard more convenient.

[0023] Among them, the positioning ring 102 is installed on the detection table 101 through the buffer assembly. A sliding groove 108 is provided on the positioning ring 102. On one side of the positioning ring 102 close to the sliding groove 108, there is also a through groove 109. The through groove 109 penetrates the sliding groove 108. The telescopic spring 104 is fixedly installed on the positioning ring 102 and is located within the sliding groove 108. The sliding clamping block 105 is fixedly installed on the telescopic spring 104. The pull rod 107 is installed on the sliding clamping block 105 through the rotational connection assembly and penetrates the through groove 109. The limiting block 106 is fixedly installed on the pull rod 107. The number of the positioning devices is three groups and they are annularly distributed on the positioning ring 102. Two telescopic springs 104 are welded on each sliding clamping block 105. The rotational connection assembly can realize the rotational connection of the pull rod 107 between the sliding clamping blocks 105. The limiting block 106 is welded on the pull rod 107. The cross-section of the limiting block 106 is the same as that of the through groove 109. The buffer assembly can provide buffering during the detection of the flower keyboard. During use, by pulling and rotating the pull rod 107, the pull rod 107 drives the limiting block 106 through the through groove 109 and is stuck on the outer side of the positioning ring 102, avoiding the need to manually maintain the position of the sliding clamping block 105 between the flower keyboards during positioning, thereby making the fixation of the flower keyboard more convenient.

[0024] Secondly, the connecting column 110 is fixedly installed on the sliding clamping block 105. A rotating groove 112 is provided inside the connecting column 110. The rotating disk 111 is rotatably installed inside the connecting column 110 and is located within the rotating groove 112. At the same time, the pull rod 107 penetrates the connecting column 110 and is fixedly connected to the rotating disk 111. The connecting column 110 is welded on the sliding clamping block 105. The rotating disk 111 is of a disk structure. Through the rotational cooperation between the connecting column 110 and the rotating disk 111, the rotational connection of the pull rod 107 between the sliding clamping blocks 105 is realized.

[0025] Thirdly, the fixed disk 113 is fixedly installed on the detection table 101. The buffer spring 114 is fixedly installed on the fixed disk 113 and is fixedly connected to the positioning ring 102. The number of the buffer springs 114 is four groups and they are annularly distributed on the fixed disk 113. Through the elastic buffering of the buffer springs 114, the impact brought by the aperture detection device to the flower keyboard can be reduced.

[0026] In this embodiment, during use, first, pull the pull rod 107 outward on the outer side of the positioning ring 102, so that the pull rod 107 drives the sliding clamping block 105 to move along the sliding groove, causing the sliding clamping block 105 to compress the telescopic spring 104. At the same time, through the rotational cooperation between the connecting column 110 and the rotating disk 111, drive the limiting block 106 on the pull rod 107 to rotate, so that the limiting block 106 aligns with the through groove 109. Then continue to pull the pull rod 107, so that the limiting block 106 passes through the through groove 109. Then, rotate the limiting block 106 again through the pull rod 107, so that the limiting block 106 is stuck on the outer side of the positioning ring 102. Then place the flower keyboard into the positioning ring 102. Through the above steps, the limiting block 106 returns to the inside of the positioning ring 102 through the through groove 109 again under the elastic force of the telescopic spring 104. At this time, the sliding clamping block 105 also fixes the flower keyboard under the elastic force of the telescopic spring 104. Then, the aperture detection device can be used to detect the flower keyboard. Thus, through multiple rotations of the limiting block 106, the limiting block 106 can be stuck on the outer side of the positioning ring 102, avoiding the need to manually maintain the position of the sliding clamping block 105 between positioning the flower keyboards, and further making the fixation of the flower keyboard more convenient.

[0027] The second embodiment of this application is:

[0028] Please refer to Figure 4 , in which Figure 4 is the overall structural schematic diagram of a flower keyboard detection device inside a dobby in the second embodiment of the present utility model. On the basis of the first embodiment, the flower keyboard detection device inside the dobby in this embodiment further includes an aperture detection device. The aperture detection device includes a detection frame 201, a measuring rod 202, and a pushing assembly. The pushing assembly includes a pushing cylinder 203 and a pushing disk 204.

[0029] In this embodiment, through the driving of the measuring rod 202 by the pushing assembly, the measuring rod 202 can detect the gasket holes and the inner diameters of the spline holes of the flower keyboard.

[0030] Among them, the detection frame 201 is fixedly installed on the detection table 101; the measuring rod 202 is installed on the detection frame 201 through the pushing assembly. The detection frame 201 is fixed to the detection table 101 by screws. The measuring rod 202 is of a cylindrical structure and is a standard measuring tool. The pushing assembly can push the measuring rod 202 to move. During use, the pushing assembly is used to push the measuring rod 202 downward and insert it into the spline hole and the gasket hole. If the measuring rod 202 can pass through the gasket hole but cannot pass through the spline hole, it is considered that the aperture of the gasket hole is within the process requirements; if the measuring rod 202 cannot pass through the gasket hole or can pass through both the gasket hole and the spline hole at the same time, the measured spline plate needs to be repaired or scrapped, thereby achieving the detection effect of the inner diameters of the gasket hole and the spline hole of the spline plate.

[0031] Secondly, the pushing cylinder 203 is fixedly installed on the detection frame 201; the pushing disk 204 is fixedly installed at the output end of the pushing cylinder 203 and is fixedly connected to the measuring rod 202. The pushing cylinder 203 is fixed to the top of the detection frame 201 by screws. The pushing disk 204 is welded to the output end of the pushing cylinder 203. The pushing disk 204 is of a disk structure. The axis of the measuring rod 202 coincides with that of the pushing disk 204. During use, the pushing cylinder 203 is started to push the pushing disk 204 downward, and the pushing disk 204 pushes the measuring rod 202 to move synchronously, thereby achieving the effect of driving the movement of the measuring rod 202.

[0032] In this embodiment, during use, the pushing cylinder 203 is started to push the pushing disk 204 downward. The pushing disk 204 pushes the measuring rod 202 downward and inserts it into the spline hole and the gasket hole. If the measuring rod 202 can pass through the gasket hole but cannot pass through the spline hole, it is considered that the aperture of the gasket hole is within the process requirements; if the measuring rod 202 cannot pass through the gasket hole or can pass through both the gasket hole and the spline hole at the same time, the measured spline plate needs to be repaired or scrapped, thereby achieving the detection effect of the inner diameters of the gasket hole and the spline hole of the spline plate.
