The existing quartz pipe piece compression resistance detection device is mostly based on a pressure testing machine as the core and is matched with a special clamp to realize pressure loading and detection. The detection process of this kind of device is usually that a single quartz piece is placed on a detection station by manual operation, and after the compression resistance test is completed by starting the equipment, the quartz piece is broken due to bearing the limit pressure, and the sharp fragments generated by the breaking need to be collected and cleaned by manual operation, and then the detection operation of the next quartz piece is performed.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following will further describe the present application in combination with specific embodiments.

[0022] In order to solve the problems of low detection efficiency and poor operation consistency in the prior art, and without manual intervention in the broken fragment collection link, the actual needs of industrialized batch detection are met, as an embodiment of the present application, as shown in Figure 1 、 Figure 2 The quartz piece compression resistance detection device provided by the present application comprises a horizontally arranged workbench 1, a detection plate 2 is slidably connected to the workbench 1, detection ports 3 are uniformly distributed on the detection plate 2 along the conveying direction, support seats 4 for supporting quartz pipe pieces are arranged on both sides of the detection ports 3, a compression resistance detection mechanism is arranged on the workbench 1, the compression resistance detection mechanism comprises a pressure detection mechanism mounted on the workbench 1 and a pressing structure arranged above the pressure detection mechanism, a material collecting structure for collecting broken quartz pipe pieces is arranged on one side of the pressure detection mechanism, and a driving device is arranged in the workbench 1 to alternately drive the detection plate 2 to move and the compression resistance detection mechanism to work.

[0023] In use, a plurality of groups of quartz pipe pieces to be detected are placed on the support seats 4, the driving device drives the detection plate 2 to move along the workbench 1 towards the compression resistance detection mechanism, when the detection plate 2 moves to a preset detection position, the driving device automatically stops driving the detection plate 2, and at this time, a group of detection ports 3 on the detection plate 2 is aligned with the compression resistance detection mechanism; With the continuous operation of the driving device, the driving device drives the pressure detection mechanism to move upward, and the pressure detection mechanism contacts the lower part of the quartz pipe after passing through the corresponding detection port 3, without manual adjustment of the relative position of the pipe and the detection mechanism, reducing the operation error and saving the manual auxiliary time; the driving device synchronously drives the extrusion structure to move downward, and the extrusion structure contacts the upper part of the quartz pipe after moving to the preset position and continuously applies uniform pressure, and the pressure sensor collects and feeds back the applied pressure value in real time until the quartz pipe reaches the compression limit and breaks; After the quartz pipe breaks, the sharp fragments generated by the breaking can fall into the material collecting structure on one side of the pressure detection mechanism, without manual picking, avoiding the risk of scratches caused by manual contact with sharp fragments; after the detection work is completed, the driving device drives the pressure detection mechanism to reset downward, and simultaneously drives the extrusion structure to reset upward to the initial state, full-automation resetting without manual intervention, shortening the interval time of single detection and further improving the detection efficiency; After the compression resistance detection mechanism resets, the driving device drives the detection plate 2 to continue sliding again, and the next group of detection ports 3 on the detection plate 2 are aligned with the compression resistance detection mechanism again, realizing continuous batch detection of the quartz pipe, shortening the batch detection cycle and reducing the labor cost.

[0024] In order to facilitate the collection of the compression resistance data of the quartz pipe, for example, as shown in Figure 1 , Figure 2 , Figure 4 illustrated, the application further comprises that the pressure detection mechanism comprises a first cylinder 5 fixedly connected vertically on the workbench 1, the output end of the first cylinder 5 is fixedly connected with a support plate 6, the upper surface of the support plate 6 is fixedly connected with a pressure sensor 7, the upper surface of the pressure sensor 7 is fixedly connected with a pressing plate 8, the upper surface of the pressing plate 8 is provided with an arc-shaped limiting groove 9, and the lower surface of the detection plate 2 is provided with a slotted opening 10 corresponding to the pressing plate 8.

[0025] In use, the driving device drives the detection plate 2 to slide smoothly along the workbench 1 towards the pressing plate 8, and in the process, the pressing plate 8 is always located in the slotted opening 10 on the lower surface of the detection plate 2, the slotted opening 10 provides a space for the pressing plate 8 to avoid structural interference between the two, ensuring smooth sliding of the detection plate 2; When the target detection port 3 on the detection plate 2 is aligned with the compression resistance detection mechanism, the driving device synchronously triggers the first cylinder 5 to start, the output end of the first cylinder 5 pushes the support plate 6 to move vertically upward, and as the support plate 6 continues to rise, the pressing plate 8 gradually passes through the target detection port 3 of the detection plate 2, and finally forms stable contact with the lower part of the quartz pipe to be detected in the detection port 3, at this time, the arc-shaped limiting groove 9 on the upper surface of the pressing plate 8 is adapted to the outer contour of the quartz pipe, realizing the circumferential positioning of the quartz pipe, effectively avoiding the radial deviation or sliding of the pipe during the extrusion process; When the extrusion structure applies pressure to the upper part of the quartz pipe, the pipe uniformly transmits the pressure to the pressing plate 8, and the pressure sensor 7 below the pressing plate 8 collects pressure data in real time and synchronously feeds back to the control end, so that the operator or the system can accurately monitor the stress state of the quartz pipe until the pipe reaches the compression limit and breaks; After the quartz pipe breaks, the first cylinder 5 drives the support plate 6 to reset vertically downward, and the pressing plate 8 moves downward synchronously with the support plate 6, and finally retreats to below the target detection port 3 of the detection plate 2; the reset pressure detection mechanism does not interfere with the subsequent sliding of the detection plate 2, and the next group of quartz pipes can be directly started for conveying and detection, effectively ensuring the efficient promotion of the continuous detection process, further shortening the batch detection cycle and reducing the time cost of industrial batch detection.

[0026] In order to facilitate the uniform pressure on the pipe, as shown in Figure 1 , Figure 5 , the extrusion structure includes a support plate 11 arranged above the pressing plate 8, the upper surface of the support plate 11 is fixedly connected with a second cylinder 12, the output end of the second cylinder 12 penetrates through the support plate 11 and is fixedly connected with a pressure block 13, and the two ends of the support plate 11 are fixedly connected with the workbench 1 through a support frame 14.

[0027] In use, when the pressing plate 8 contacts and positions the lower part of the quartz pipe, the driving device synchronously controls the second cylinder 12 to start, the second cylinder 12 drives the pressure block 13 to move vertically downward, and when the pressure block 13 continuously moves downward to contact the upper part of the quartz pipe, the second cylinder 12 continues to output stable thrust to apply uniform pressure to the pipe through the pressure block 13, and when the quartz pipe reaches the compression limit and breaks, the second cylinder 12 drives the pressure block 13 to reset quickly upward to the initial high position.

[0028] In order to avoid the pipe from shifting or shaking due to pressure during detection, as shown in Figure 1 , Figure 3 , Figure 6 , Figure 7 , the support seat 4 is provided with a clamping groove 15, the clamping groove 15 is provided with a mounting groove 16, the mounting groove 16 is provided with an expansion pad 17, the lower surface of the detection plate 2 is provided with a plurality of groups of one-way air inlet joints 18 corresponding to the support seat 4, the one-way air inlet joint 18 is provided with a sealing ring, the one-way air inlet joint 18 is in communication with the expansion pad 17, and the outer side of the support seat 4 is provided with a damping exhaust valve 19 in communication with the expansion pad 17; the support plate 6 is provided with a clamping communication structure that is in butt joint with the corresponding one-way air inlet joint 18.

[0029] In use, the driving device drives the detection plate 2 to slide along the workbench 1 to a preset detection position, so that the target detection port 3 on the detection plate 2 is aligned with the compression resistance detection mechanism, and the driving device drives the support plate 6 to vertically move upward; when the support plate 6 moves to a preset height, the clamping communication structure on the support plate 6 is clamped with the corresponding one-way air inlet joint 18; the sealing ring in the one-way air inlet joint 18 can enhance the sealing performance of the joint, so as to avoid gas leakage; the gas is conveyed into the inflation pad 17 through the clamping communication structure and the one-way air inlet joint 18; after the inflation pad 17 is inflated, it is uniformly inflated to apply clamping force to the quartz pipe, so as to avoid the pipe from being deviated or shaken due to pressure during the detection process, and ensure the accuracy of the detection data. After the quartz pipe compression detection is completed and broken, the driving device drives the support plate 6 to vertically move downward, and the clamping communication structure moves downward synchronously with the support plate 6, and is disconnected with the one-way air inlet joint 18, so as to facilitate subsequent connection with the one-way air inlet joint 18 below the next group of support seats 4. During the movement of the detection plate 2, when the next group of quartz pipes to be detected is aligned with the pressure detection mechanism, the quartz pipe which has completed the detection at the front end loses the support force due to the middle broken, at this time, the gas in the inflation pad 17 is slowly discharged through the damping exhaust valve 19 outside the support seat 4, the inflation pad 17 gradually shrinks, and the clamping force on the broken quartz pipe is no longer applied, so that the two broken quartz pipes can fall downward through the detection port 3, and the fragments finally fall into the collection structure below, realizing automatic discharge without manual picking up of the fragments, avoiding the risk of scratches caused by manual contact with the fragments, and saving the manual cleaning step, thereby further improving the detection efficiency.

[0030] For example, as shown in the drawings, Figure 2 , Figure 4 For example, the application also includes that the clamping communication structure includes connecting rods 20 connected to both sides of the support plate 6, and the connecting rods 20 are fixedly connected with communication joints 21 at the ends, and the communication joints 21 are connected with the corresponding one-way air inlet joints 18 after the support plate 6 moves upward.

[0031] In use, when the driving device drives the support plate 6 to vertically move upward, the connecting rods 20 on both sides of the support plate 6 move upward synchronously with the support plate 6; as the support plate 6 continues to move upward to a preset detection position, the communication joints 21 are aligned with and connected with the corresponding one-way air inlet joints 18; after the connection is completed, the gas enters the one-way air inlet joint 18 through the communication joint 21, and then enters the inflation pad 17, so as to complete the clamping and positioning of the quartz pipe, shorten the preparation time of single detection, and improve the detection efficiency. After the quartz pipe detection is completed, the driving device drives the support plate 6 to vertically move downward, and the connecting rods 20 drive the communication joints 21 to move downward synchronously, and the communication joints 21 are smoothly disconnected with the one-way air inlet joints 18.

[0032] In order to facilitate the movement of the detection plate 2, for example, as shown in the drawings,Figure 1 、 Figure 8 、 Figure 9 As shown in FIGS. 1, 2 and 3, the workbench 1 is provided with a sliding groove 22, a plurality of sliding blocks 23 are slidingly connected in the sliding groove 22, the detection plate 2 is fixedly connected with the upper surface of the sliding block 23, the lower surface of the sliding block 23 is fixedly connected with a sliding seat 24, the sliding seat 24 is provided with a threaded hole, a screw rod 25 is threadedly connected in the threaded hole, one end of the screw rod 25 is fixedly connected with the lower surface of the workbench 1 through a rotating bearing seat, and the other end of the screw rod 25 is fixedly connected with a first gear 26; and the driving device is in meshing transmission with the first gear 26.

[0033] In use, the driving device drives the first gear 26 to rotate, the first gear 26 drives the screw rod 25 to synchronously rotate, the screw rod 25 is in meshing transmission with the sliding seat 24 through the threaded hole, drives the sliding block 23 to stably slide along the sliding groove 22 of the workbench 1, and the sliding block 23 drives the detection plate 2 to synchronously move until the target detection port 3 is aligned with the detection mechanism, thereby improving detection consistency and shortening work station switching time.
