Description

Technical Field

[0001] The utility model relates to the technical field of quartz glass material detection, in particular to a high-temperature hot bending performance detection bracket for quartz glass. Background Art

[0002] Quartz glass is a special glass containing only silicon dioxide as a single component. Due to the differences in types, processes, and raw materials, it is often called silicate glass, quartz glass, fused quartz, fused quartz, synthetic fused quartz, and transparent, translucent, opaque quartz, etc., which have no clear concept. Quartz glass has extremely low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best ultraviolet spectrum performance, visible light and near-infrared spectrum performance, and has higher mechanical properties than ordinary glass.

[0003] Quartz glass may deform after being used for a long time under high temperature conditions. In order to test the ability of quartz glass to resist deformation under high temperature conditions, the sample material will be tested for high temperature hot bending performance before each batch of quartz glass is produced and processed to test the highest temperature that the batch of materials can withstand, so as to prevent the quartz glass from having poor high temperature resistance and variability after production. Ordinary testing devices usually have the following problems when testing the hot bending performance of samples:

[0004] 1. During the test, in order to prevent the sample from shifting during the test, a special fixture is used to limit and fix the test sample. The ordinary limit device can only fix one sample at a time, and cannot fix multiple different samples at the same time, resulting in low test efficiency;

[0005] 2. Most of the fixtures are customized according to the size of the sample. The limit range of the fixture is relatively fixed. It can only perform one-way upper and lower limits or left and right limits, and cannot be flexibly adjusted according to the thickness of the sample, and has low compatibility. Utility Model Content

[0006] The purpose of the utility model is to provide a high-temperature hot bending performance testing bracket for quartz glass, so as to solve the problems that the common testing equipment proposed in the above background technology cannot fix multiple samples synchronously for testing, can only limit in one direction when limiting, and cannot adjust the position of the clamp according to the thickness of the sample, and has low compatibility. To achieve the above purpose, the utility model provides the following technical solutions: A high-temperature hot bending performance testing bracket for quartz glass, including a base, a limiting mechanism is slidably connected to the top of the base, and a pressing mechanism is installed above the limiting mechanism.

[0007] The limiting mechanism includes an upper pressing plate, the surface of the upper pressing plate is provided with a sliding groove, the interior of the sliding groove is slidably connected with a clamping plate, the back of the clamping plate is slidably connected with a support rod, the lower surface of the upper pressing plate is welded with a limiting rod, the back of the support rod is installed with a piston rod of a hydraulic rod, and the outside of the hydraulic rod is sleeved with a mounting seat.

[0008] The pressing mechanism comprises a screw rod, a small gear is inserted at the top of the screw rod, and a large gear is meshed at the side of the small gear.

[0009] Further preferably, there are six slide grooves in total, and each slide groove is equipped with a clamping plate.

[0010] Further preferably, the mounting seat and the upper pressing plate are connected by welding, and the upper pressing plate and the base are connected by sliding.

[0011] Further preferably, the support rod is connected to the lower surface of the limiting rod in a sliding manner, and the support rod is configured to perform linear motion via a hydraulic rod.

[0012] Further preferably, there are two screw rods in total, and the screw rods are connected to the upper pressing plate by threaded connection.

[0013] Further preferably, a meshing transmission structure is provided between the large gear and the small gear.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, a plurality of slide grooves and clamping plates are added inside the upper pressing plate, and six slide grooves are distributed side by side on the surface of the upper pressing plate, and a certain spacing is set between the six slide grooves, and the spacing decreases successively from the beginning to the end. A clamping plate is slidably connected in each slide groove, and under the drive of the hydraulic rod, different samples can be clamped and fixed at the same time for testing, and the detection efficiency is higher.

[0016] In the utility model, by adjusting the distance between the clamping plates and cooperating with the pressing mechanism to adjust the downward movement of the upper pressing plate, when the large gear rotates forward, the small gears on both sides meshing with the large gear begin to rotate counterclockwise, and when it rotates reversely, they rotate clockwise. Through the transmission of the large gear, the small gears on both sides rotate in the same direction and at the same speed, which drives the rotation frequency and rotation direction of the screw rod at the bottom to be consistent, thereby realizing double-sided limitation of samples of different sizes on the upper and lower sides and on the left and right sides, and having higher compatibility.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a high-temperature hot bending performance detection bracket for quartz glass, comprising a base 1, a limiting mechanism 2 is slidably connected above the base 1, and a pressing mechanism 3 is installed above the limiting mechanism 2.

[0024] The limiting mechanism 2 includes an upper pressing plate 201, a surface of which is provided with a slide groove 202, the interior of the slide groove 202 is slidably connected with a clamping plate 203, the back of the clamping plate 203 is slidably connected with a support rod 204, a limiting rod 205 is welded to the lower surface of the upper pressing plate 201, the back of the support rod 204 is installed with a piston rod of a hydraulic rod 206, and the outer part of the hydraulic rod 206 is sleeved with a mounting seat 207.

[0025] The pressing mechanism 3 comprises a screw rod 301 , a small gear 302 is inserted into the top of the screw rod 301 , and a large gear 303 is meshed with the side of the small gear 302 .

[0026] In this embodiment, Figure 3 As shown, there are six slide grooves 202 in total, and each slide groove 202 is equipped with a clamping plate 203; it should be noted that the six slide grooves 202 are distributed side by side on the surface of the upper pressing plate 201, and a certain distance is set between the six slide grooves 202, and the distance decreases successively from the beginning to the end, and each slide groove 202 is slidably connected to a clamping plate 203. When samples need to be tested, samples made of different materials can be placed between two clamping plates 203 and clamped and fixed by the clamping plates 203.

[0027] In this embodiment, Figure 1 and Figure 3 As shown, the mounting seat 207 and the upper pressing plate 201 are welded, and the upper pressing plate 201 and the base 1 are connected by sliding. It should be noted that the mounting seat 207 and the upper pressing plate 201 are welded together, and the hydraulic rod 206 is fixed by the mounting seat 207. When the upper pressing plate 201 slides up and down along the base 1, the mounting seat 207 and the hydraulic rod 206 are driven to slide up and down synchronously.

[0028] In this embodiment, Figure 1 and Figure 4 As shown, the support rod 204 and the lower surface of the limiting rod 205 are connected in a sliding manner, and the support rod 204 forms a linear motion through the hydraulic rod 206; it should be noted that the limiting rod 205 supports the support rod 204, and when the hydraulic rod 206 is started, the piston rod of the hydraulic rod 206 pushes the support rod 204 forward, and the support rod 204 moves forward in a linear motion, sliding along the limiting rod 205 during the movement. As the piston rod of the hydraulic rod 206 is extended, the spacing between the splints 203 decreases, while the spacing increases. The spacing between the splints 203 can be adjusted according to the thickness of the sample to be tested.

[0029] In this embodiment, Figure 2 As shown, there are two screw rods 301, and the screw rods 301 and the upper pressing plate 201 are connected by threads. It should be noted that the upper pressing plate and the screw rods 301 are connected by threads, and as the screw rods 301 rotate, the upper pressing plate 201 is driven to move up and down parallel to the screw rods 301.

[0030] In this embodiment, Figure 2 As shown, a meshing transmission structure is set between the large gear 303 and the small gear 302; it should be noted that a lever is provided on the top of the large gear 303. When the lever is pushed, the large gear 303 is driven to rotate forward, and the small gears 302 on both sides meshing with the large gear 303 begin to rotate counterclockwise, and rotate clockwise otherwise. Through the transmission of the large gear 303, the small gears 302 on both sides rotate in the same direction and at the same rotation rate, driving the screw rod 301 at the bottom to rotate at the same frequency and direction.

[0031] The use method and advantages of the utility model: The high temperature bending performance detection bracket for quartz glass has the following working process when in use:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the sample to be tested is placed between the two clamping plates 203. The clamping plates 203 are provided with six pieces to prevent three groups of samples at the same time. The hydraulic rod 206 is started, and the piston rod of the hydraulic rod 206 pushes the support rod 204 forward. The support rod 204 moves forward in a straight line and slides along the limit rod 205 during movement. As the piston rod of the hydraulic rod 206 extends, the spacing between the clamping plates 203 decreases until the clamping plates 203 clamp the left and right sides of the sample. The hydraulic rod 206 stops moving, and then according to the overall thickness of the upper and lower parts of the sample, the large gear 303 is rotated and the large gear 303 is toggled. The large gear 303 is reversed, and the small gears 302 and the screw rod 301 on both sides start to rotate forward, and the upper pressing plate 201 moves downward. When the upper pressing plate 201 moves downward, it drives the clamping plate 203 to move downward synchronously until the upper pressing plate 201 is tightly against the upper surface of the sample, and the sample is synchronously limited on both sides, to prevent the sample from being displaced during the detection process.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
