Description

Technical Field

[0001] The invention relates to the technical field of material compression resistance detection, and in particular to a compression resistance detection device and a detection method based on the production of a solid watercolor palette. Background Art

[0002] Compression testing is a key means of evaluating the structural strength and durability of watercolor palettes. By simulating the pressure conditions that may be encountered in actual use, it can ensure that the palette will not deform, crack or be damaged due to pressure during transportation, storage and use, thereby maintaining its integrity and functionality. If the palette is prone to cracking under pressure, it may cause the watercolor paint inside to leak, which will not only damage the palette itself, but may also cause contamination to the user's artwork, work area and even clothing. Compression testing helps identify and eliminate these potential safety risks; For example, the prior art publication number is CN217484028U, and the patent disclosed is named: A patent for a pressure-resistant detection device for processing plastic products, which includes: a base; and a support plate, which is fixedly connected to the base; a top seat, which is fixedly connected to the support plate and is not connected to the top of the base; a detection structure, which is arranged on the top of the base for detecting pressure; a movable seat, which is slidably arranged on the bottom of the top seat; a driving structure, which is arranged inside the top seat for driving the movable seat to move up and down; a rotating structure, which is rotatably arranged on the bottom of the movable seat; and a plurality of lower pressure plates, which are detachably arranged on the bottom of the rotating structure. The utility model provides a pressure-resistant detection device for processing plastic products, which can detect the pressure resistance of plastic products under the action of different force-bearing surfaces, and can replace and adjust the force-bearing surfaces to be detected as needed, has better adaptability, and is more convenient for users to perform pressure resistance detection; Since the watercolor palette box includes a number of densely distributed paint grooves for holding paints, after the palette box has been used for a period of time, the solidified paint in the paint grooves needs to be cleaned, so it is necessary to ensure that the strength of the side wall portion of the paint groove is high to prevent damage to the portion during cleaning, so it is necessary to perform a compression test on the portion. The problem with the above-mentioned prior art is that since the driving structure can only drive the movable seat to move up and down, when performing a compression test on the plastic product (which is equivalent to the watercolor palette box body of the present application), only the upper and lower parts of the plastic product can be tested, so it is necessary to improve this. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] The present invention provides a compression resistance detection device and detection method based on the production of a solid watercolor palette, which can solve the problem that the existing technology cannot perform compression resistance detection on the inner wall of a pigment tank. The specific scheme is as follows: In one aspect, the present invention provides a compression resistance detection device produced based on a solid watercolor palette, comprising: Base, placed on the ground; A cover plate is mounted on the top of the base through a hydraulic rod, and the distance between the bottom of the cover plate and the top of the base is adjusted by the hydraulic rod; A lower pressing block, the bottom of which is connected with a lower pressing plate and is installed below the cover plate; The bottom of the lower pressing plate is provided with an extrusion assembly, and the extrusion assembly comprises: A movable block is installed at the bottom of the lower pressing plate. A receiving groove is provided at the bottom of the lower pressing plate. The depth of the receiving groove is greater than the height of the movable block. The movable block is connected by sliding up and down inside the receiving groove. There are two extrusion blocks, each of which consists of a sliding portion and a contact portion, wherein the sliding portion is located inside the movable block, and the two extrusion blocks are symmetrically arranged at both ends of the movable block, and an inclined surface is arranged at one adjacent end of the two extrusion blocks; The squeezing plate is slidably mounted inside the movable block. When the squeezing plate moves downward, the bottom end of the squeezing plate contacts the inclined surfaces at the tops of the two squeezing blocks, thereby driving the two squeezing blocks to move away from each other and squeezing the inner wall of the pigment groove of the watercolor palette body.

[0005] Preferably, the extrusion assembly further comprises: An active cavity is provided at the lower part of the active block, the sliding part is slidably connected with the inside of the active cavity, rectangular grooves are provided on both sides of the active cavity, and the contact part passes through the rectangular grooves to the outside of the active block; A motor is fixedly mounted on the top of the inner wall of the accommodating groove, a screw rod is connected to the bottom output end of the motor, and the screw rod is threadedly connected to the top of the movable block. When the motor drives the screw rod to rotate, the movable block slides up and down along the inside of the accommodating groove.

[0006] Preferably, when the movable block moves upward and the bottom of the lower pressure plate abuts against the top surface of the watercolor palette box body, and a gap is formed between the bottom of the movable block and the inner bottom of the pigment groove on the watercolor palette box body, the lower pressure plate can squeeze the watercolor palette box body in the direction of the plumb line, thereby detecting the compression resistance of the watercolor palette box body.

[0007] Preferably, the extrusion assembly further comprises: A telescopic member, mounted on the upper portion of the extrusion plate, for driving the extrusion plate to move up and down in the movable block; A first spring, one end of the first spring is fixedly connected to one end of the sliding portion, and the other end of the first spring is fixedly connected to the inner wall of the movable cavity. The first spring is in an extended state by default. In the absence of external force, the first spring can cause the two extrusion blocks to move closer to each other. When the extrusion plate is extruded downward, the elastic force of the first spring can be overcome, thereby driving the two extrusion blocks to expand to both sides.

[0008] Preferably, it also includes a fixing component, and the fixing component includes: A first rotating ring is installed at the bottom of the base, an annular cavity is provided inside the base, the shape of the annular cavity matches the shape of the first rotating ring, and the first rotating ring rotates inside the annular cavity; There are four support blocks, which are installed around the detection station on the top of the base, extend to the top of the detection station and support the bottom of the watercolor palette box body. A sliding groove is opened inside the base, and the support blocks are slidably connected to the sliding groove, and the sliding groove extends to the inside of the annular cavity.

[0009] Preferably, the fixing assembly further comprises: A driving block, wherein the driving block is evenly arranged on the top of the first rotating ring, and an arc transition is arranged at one end of the driving block close to the supporting block. When the driving block rotates toward the side of the arc transition, the supporting block can be driven to move upward under the squeezing action of the driving block to support the watercolor palette box body; The second spring is fixedly connected to the bottom of the support block, and the bottom of the second spring is connected to the bottom of the inner wall of the sliding groove. By setting the second spring, when there is no need to support the watercolor palette body, the support block drops to the lowest position under the recovery state of the second spring and the deadweight of the support block.

[0010] Preferably, the fixing assembly further comprises: A second rotating ring is rotatably mounted in the detection station on the top of the base, and a convex block is arranged on the inner side of the second rotating ring, and the convex block is in an arc shape; A clamping block, the number of which corresponds to the position of each corner of the watercolor palette body, the clamping block is slidably installed on the top of the support block, the clamping block corresponds to the position of the protrusion, and when the second rotating ring rotates, the protrusion can press the clamping block toward the center direction of the base, so that the clamping block and the corner of the watercolor palette body are abutted, and the watercolor palette body is clamped by the action of multiple clamping blocks.

[0011] Preferably, a third spring is connected to the bottom of the clamping block, a slider is fixedly connected to the bottom of the clamping block, the third spring is fixedly connected to one end of the slider, a sliding groove is provided on the top of the support block, the slider is slidably connected to the sliding groove, the other end of the third spring is fixedly connected to the inner wall of the sliding groove, and the third spring is a compression spring.

[0012] Preferably, a stopper is connected to the top end of the driving block, and the stopper is used to prevent the supporting block from sliding to the right-angle side of the driving block.

[0013] On the other hand, the present invention provides a compression resistance detection method based on the production of a solid watercolor palette, comprising the following steps: S1. Install the base on the floor of the plant and fix it with bolts and shock-absorbing pads. Place a cover plate on the top of the base. Install a hydraulic rod between the cover plate and the base to adjust the distance between the cover plate and the base. S2. A lower pressing block is arranged at the bottom of the cover plate, the bottom of the lower pressing block is connected to the lower pressing plate, and the lower pressing block can move up and down under the action of the driving member; S3, placing the watercolor palette box body to be tested in the testing station on the top of the base, and fixing the watercolor palette box body by a tooling; S4. During the test, by controlling the air pressure, the lower pressing block and the lower pressing plate are subjected to a certain pressure downward and maintained within a set time under the action of the air pressure, and the applied force is gradually increased until the watercolor palette box body is squeezed and deformed, and the pressure resistance value of the watercolor palette box body can be obtained; S5. When it is necessary to perform a pressure test on the side wall of the pigment slot of the watercolor palette body, move the movable block downward so that the movable block is located in the pigment slot, and then move the extrusion plate downward to drive the two extrusion blocks to move to both sides to squeeze the side wall of the pigment slot, and gradually increase the power of the extrusion plate driving source as the extrusion plate moves downward until the side wall of the pigment slot can be deformed at a certain power, so that the pressure resistance of the side wall of the pigment slot can be detected.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. By setting a lower pressure plate and applying a stable downward pressure to the lower pressure plate through an external high-pressure air source, the watercolor palette box body installed on the top of the base can be subjected to an extrusion test, and by setting an extrusion assembly at the lower part of the lower pressure plate, the side wall of the pigment groove on the watercolor palette box body is laterally extruded by two extrusion blocks on the extrusion assembly, so as to detect the compressive strength of the thinner position of the watercolor palette box body, thereby performing a comprehensive test on the watercolor palette box body, and obtaining more accurate test results than traditional testing technologies.

[0015] 2. By setting a movable block that can move up and down, when there is no need to perform lateral compression test on the watercolor palette box body, the motor can drive the screw rod to rotate to one side to make the movable block rise. In this state, the bottom of the lower pressure plate is against the top surface of the watercolor palette box body, and the bottom of the movable block does not contact the inner bottom of the pigment groove on the watercolor palette box body. At this time, the lower pressure plate can squeeze the watercolor palette box body in the direction of the plumb line, thereby detecting the compression performance of the watercolor palette box body.

[0016] 3. The second rotating ring rotates to drive the convex block to rotate synchronously. The convex block can squeeze the clamping block toward the center of the base, so that the clamping block and the corner of the watercolor palette body are abutted. Through the action of multiple clamping blocks, the watercolor palette body can be clamped, thereby preventing the watercolor palette body from shifting during the compression test, thereby ensuring the accuracy of the test result.

[0017] 4. The first rotating ring rotates to drive the support block to move upward, and at the same time, under the action of high-pressure gas, the lower pressure block and the lower pressure plate apply stable pressure downward, thereby performing a pressure test on the watercolor palette box body. During the test, the support block is driven upward by the first rotating ring, and the pressure applied to the watercolor palette box body can be fine-tuned. The pressure value adjusted by rotating in a gear meshing manner is more stable than air pressure adjustment.

[0018] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

DETAILED DESCRIPTION

[0021] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0022] Example 1: See Figure 1-Figure 4 This embodiment provides a compression resistance detection device based on a solid watercolor palette, comprising: The base 101 is placed on the floor of the workshop where the parts to be inspected are located, and is fixed to the floor by bolts and shock-absorbing pads to prevent displacement and vibration during operation; The cover plate 102 is mounted on the top of the base 101 through a hydraulic rod, and the distance between the bottom of the cover plate 102 and the top of the base 101 can be adjusted through the hydraulic rod, so as to facilitate the placement of the watercolor palette body 2 into the detection station on the base 101; The lower pressing block 104 is connected with the lower pressing plate 105 at the bottom and is installed under the cover plate 102. The top of the cover plate 102 is provided with a sealing sleeve 103. The sealing sleeve 103 and the cover plate 102 are formed in one piece. The top of the lower pressing block 104 is sealingly and slidably connected with the inside of the sealing sleeve 103. The upper and lower ends of the sealing sleeve 103 are respectively provided with two for connecting the high-pressure gas source. When the high-pressure gas is injected into the sealing sleeve 103 from the air inlet at the top, it can generate downward pressure on the lower pressing block 104. When the high-pressure gas is injected into the sealing sleeve 103 from the air inlet at the bottom, the high-pressure gas acts on the bottom of the lower pressing block 104, which can generate an upward thrust on the lower pressing block 104, thereby pushing the lower pressing block 104 and the lower pressing plate 105 upward; like Figure 1 As shown, the watercolor palette box body 2 is placed in the detection station on the top of the base 101, and the tooling in the detection station can fully clamp the watercolor palette box body 2 to prevent the watercolor palette box body 2 from shifting in the detection station.

[0023] like Figure 2 As shown, a squeezing assembly 3 is provided at the bottom of the lower pressing plate 105, and the squeezing assembly 3 is used to squeeze the watercolor palette body 2 in the lateral direction, and the squeezing assembly 3 includes: The movable block 301 is installed at the bottom of the lower pressing plate 105. The bottom of the lower pressing plate 105 is provided with a receiving groove. The depth of the receiving groove is greater than the height of the movable block 301. The movable block 301 is connected by sliding up and down inside the receiving groove. There are two extrusion blocks, each of which is composed of a sliding portion 302 and a contact portion 303. The sliding portion 302 is located inside the movable block 301. The two extrusion blocks are symmetrically arranged at both ends of the movable block 301. An inclined surface 311 is arranged at one adjacent end of the two extrusion blocks. The squeezing plate 304 is slidably mounted inside the movable block 301. When the squeezing plate 304 moves downward, the bottom end of the squeezing plate 304 contacts the inclined surfaces 311 on the tops of the two squeezing blocks, thereby driving the two squeezing blocks to move away from each other. When the anti-squeezing test is performed on the watercolor palette box body 2, the movable block 301 can be first extended into the pigment groove on the watercolor palette box body 2, and then expanded by the two squeezing blocks to squeeze the side wall of the pigment groove on the watercolor palette box body 2, and a stable downward pressure is applied to the squeezing plate 304, so that the two squeezing blocks can apply a stable pressure to the side wall of the pigment groove of the watercolor palette box body 2, thereby detecting the anti-squeezing limit of the watercolor palette box body 2; The movable cavity 309 is provided at the lower part of the movable block 301. The sliding part 302 is slidably connected with the inside of the movable cavity 309. Rectangular grooves 310 are provided on both sides of the movable cavity 309. The contact part 303 passes through the rectangular grooves 310 to the outside of the movable block 301. The motor 305 is fixedly mounted on the top of the inner wall of the accommodating groove. The bottom output end of the motor 305 is connected with a screw rod 306. The screw rod 306 is threadedly connected to the top of the movable block 301. When the motor 305 drives the screw rod 306 to rotate, the movable block 301 can slide up and down along the inside of the accommodating groove. Therefore, when it is not necessary to perform a lateral pressure resistance test on the watercolor palette box body 2, the motor 305 can drive the screw rod 306 to rotate to one side to make the movable block 301 rise. In this state, the bottom of the lower pressure plate 105 is against the top surface of the watercolor palette box body 2, and the bottom of the movable block 301 is not in contact with the inner bottom of the pigment groove on the watercolor palette box body 2. At this time, the lower pressure plate 105 can squeeze the watercolor palette box body 2 in the direction of the plumb line, thereby detecting the pressure resistance of the watercolor palette box body 2. The telescopic member is mounted on the upper part of the extrusion plate 304 and is used to drive the extrusion plate 304 to move up and down in the movable block 301. Figure 3 As shown, the telescopic member is a first electric telescopic rod 307, the interior of the screw rod 306 is hollow, the top of the first electric telescopic rod 307 is fixedly installed inside the screw rod 306, and the bottom of the first electric telescopic rod 307 is rotatably connected to the top of the extrusion plate 304; as another way, Figure 4 As shown, the telescopic member may be a second electric telescopic rod 308, and the upper and lower ends of the second electric telescopic rod 308 are fixedly connected to the top of the movable block 301 and the top of the extrusion plate 304 respectively; The first spring 312, such as Figure 2 , Figure 3 As shown, one end of the first spring 312 is fixedly connected to one end of the sliding portion 302, and the other end of the first spring 312 is fixedly connected to the inner wall of the active cavity 309. The default state of the first spring 312 is extension. In the absence of external force, the first spring 312 can cause the two extrusion blocks to move closer to each other. When the extrusion plate 304 is pressed downward, the elastic force of the first spring 312 can be overcome, thereby driving the two extrusion blocks to expand to both sides. In the above scheme, by providing a lower pressing plate 105 and applying a stable pressure downward to the lower pressing plate 105 through an external high-pressure air source, the watercolor palette box body 2 installed on the top of the base 101 can be subjected to an extrusion test, and by providing an extrusion assembly 3 at the lower part of the lower pressing plate 105, the side wall of the pigment groove on the watercolor palette box body 2 is laterally extruded by two extrusion blocks on the extrusion assembly 3, so as to detect the compressive strength of the thinner position of the watercolor palette box body 2, thereby performing a comprehensive test on the watercolor palette box body 2, and more accurate test results can be obtained compared with traditional test technologies.

[0024] Embodiment 2: Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the technical solution of this embodiment is different from that of the first embodiment in that this embodiment further includes a fixing component 4, and the fixing component 4 includes: The first rotating ring 401 is installed at the bottom of the base 101. An annular cavity is provided inside the base 101. The shape of the annular cavity matches the shape of the first rotating ring 401. The first rotating ring 401 rotates inside the annular cavity. As a feasible solution, the driving source of the first rotating ring 401 can be a circle of teeth arranged around it, and then the driving device drives the gear to rotate, so that the gear meshes with the teeth, thereby driving the first rotating ring 401 to rotate; There are four support blocks 404, which are installed around the detection station on the top of the base 101, extending above the detection station and supporting the bottom of the watercolor palette body 2. A sliding groove 406 is provided inside the base 101, and the support blocks 404 are slidably connected to the sliding groove 406, and the sliding groove 406 extends to the inside of the annular cavity; The driving block 402 is evenly arranged on the top of the first rotating ring 401. The end of the driving block 402 close to the supporting block 404 is provided with an arc transition. The top of the driving block 402 is connected with a stopper 403. When the driving block 402 rotates toward the side of the arc transition, the supporting block 404 can be driven to move upward under the squeezing effect of the driving block 402, so as to support the watercolor palette box body 2; The second spring 405 is fixedly connected to the bottom of the support block 404. The bottom of the second spring 405 is connected to the bottom of the inner wall of the sliding groove 406. By setting the second spring 405, when there is no need to support the watercolor palette body 2, under the recovery state of the second spring 405 and the deadweight of the support block 404, the support block 404 drops to the lowest position, and the bottom of the support block 404 is used to block the upper opening of the sliding groove 406 to prevent dust from entering the interior of the sliding groove 406. In the above scheme, the first rotating ring 401 rotates to drive the support block 404 to move upward, and at the same time, under the action of high-pressure gas, the lower pressing block 104 and the lower pressing plate 105 apply stable pressure downward, so as to perform a pressure test on the watercolor palette box body 2. During the test, the first rotating ring 401 drives the support block 404 to move upward, and the pressure applied to the watercolor palette box body 2 can be fine-tuned. The pressure value adjusted by rotating in a gear meshing manner is more stable than that of air pressure regulation. The factors that lead to unstable air pressure regulation are as follows: 1) The air regulating valve adjusts the air too low: If the air regulating valve adjusts the air too low, the air pressure will not reach the set value, which will cause air pressure fluctuations; 2) The gas path is blocked: If the pipes, joints and other parts in the gas path are blocked or leaking, it will affect the flow of gas, resulting in unstable gas pressure regulation; 3) Impact of working environment: The working environment of the air pressure system, such as temperature, humidity, vibration, etc., will also affect the stability of the air pressure. For example, high temperature may cause the components to expand and deform, and vibration may cause the components to loosen or be damaged. 4) Insufficient air input: If the air input of the air compressor is lower than the system demand, the air pressure regulation will be unstable. This may be caused by performance problems of the air compressor itself or insufficient external air supply.

[0025] like Figure 8 , Fig. 9 As shown, the fixing assembly 4 also includes: The second rotating ring 407 is rotatably mounted in the detection station on the top of the base 101. A protrusion 408 is provided on the inner side of the second rotating ring 407. The protrusion 408 is arc-shaped. As a driving method of the second rotating ring 407, teeth are provided around the second rotating ring 407, and then the gear is driven to rotate by an external driving device, and then the gear is meshed with the teeth, thereby driving the second rotating ring 407 to rotate; The number of the clamping blocks 409 corresponds to the position of each corner of the watercolor palette body 2. The clamping blocks 409 are slidably mounted on the top of the support block 404. The positions of the clamping blocks 409 and the protrusions 408 correspond. When the second rotating ring 407 rotates, the protrusions 408 can squeeze the clamping blocks 409 toward the center of the base 101, so that the clamping blocks 409 and the corners of the watercolor palette body 2 are abutted. Through the action of multiple clamping blocks 409, the watercolor palette body 2 can be clamped, thereby preventing the watercolor palette body 2 from deviating during the compression test, thereby ensuring the accuracy of the test results. Fig.10 is a schematic diagram of the state change of the second rotating ring 407; The third spring 410 is connected to the bottom of the clamping block 409, and a slider 412 is fixedly connected to the bottom of the clamping block 409. The third spring 410 is fixedly connected to one end of the slider 412. A slide groove 411 is provided on the top of the support block 404. The slider 412 is slidably connected to the slide groove 411. The other end of the third spring 410 is fixedly connected to the inner wall of the slide groove 411. The third spring 410 is a compression spring. Fig.11 As shown, it is a state diagram of the watercolor palette body 2 being clamped by the clamping block 409; It should be noted that in the above solution, the height of the second rotating ring 407 is constant, and a ring groove matching the second rotating ring 407 is opened on the side wall of the detection station of the base 101, and the second rotating ring 407 rotates in the ring groove.

[0026] Example 3: See Figure 1-11 The technical solution of this embodiment is different from that of the second embodiment in that this embodiment discloses a compression resistance detection method based on the production of a solid watercolor palette, comprising the following steps: S1. Install the base 101 on the floor of the factory building and fix it with bolts and shock-absorbing pads. Place a cover plate 102 on the top of the base 101. Install a hydraulic rod between the cover plate 102 and the base 101 to adjust the distance between the cover plate 102 and the base 101. S2. A lower pressing block 104 is provided at the bottom of the cover plate 102. The bottom of the lower pressing block 104 is connected to the lower pressing plate 105. The lower pressing block 104 can move up and down under the action of the driving member; S3, placing the watercolor palette box body 2 to be tested in the testing station on the top of the base 101, and fixing the watercolor palette box body 2 by a tool; S4, during the test, by controlling the air pressure, under the action of the air pressure, the lower pressing block 104 and the lower pressing plate 105 are subjected to a certain pressure downward and maintained within a set time, and the applied force is gradually increased until the watercolor palette box body 2 is squeezed and deformed, and the pressure resistance value of the watercolor palette box body 2 can be obtained; S5. When it is necessary to perform a pressure test on the side wall of the pigment groove of the watercolor palette body 2, the movable block 301 is moved downward so that the movable block 301 is located in the pigment groove, and then the squeezing plate 304 is moved downward to drive the two squeezing blocks to move to both sides to squeeze the side wall of the pigment groove, and when the squeezing plate 304 moves downward, the power of the driving source of the squeezing plate 304 is gradually increased until the side wall of the pigment groove can be deformed at a certain power, so that the pressure resistance strength of the side wall of the pigment groove can be detected.
