Description

Technical Field

[0001] The utility model relates to the technical field of textile testing equipment, and particularly to a clamping device for testing the color fastness of fabrics under sunlight climate. Background Technique

[0002] During the process of testing the color fastness of textiles under sunlight climate, it is necessary to clamp the textiles by a clamping mechanism, and then place the textiles around a xenon arc lamp, and use the xenon arc lamp to simulate the sunlight environment, so as to test the color fastness of the textiles on the clamping mechanism.

[0003] The existing invention patent with the authorized announcement number of CN112557288B discloses a fabric color fastness tester. Among them, the textile is fixed on the mounting rack, and then the mounting rack is inserted into the slot on the base, so that the textile stands on the periphery of the xenon arc lamp. Among them, the mounting rack and the slot only have an insertion relationship. During the rotation of the base, it is easy to cause the mounting rack to shake. Seriously, the mounting rack will fall off from the slot, affecting the color fastness test of the textile.

[0004] Therefore, how to design a clamping device that improves the stability of textiles has become a technical problem that needs to be solved urgently by those skilled in the art. Content of the Utility Model

[0005] In order to solve at least one technical problem mentioned in the background technique, the purpose of the utility model is to provide a clamping device for testing the color fastness of fabrics under sunlight climate, so as to solve the problem that the mounting rack is easy to shake when inserted into the slot.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A clamping device for testing the color fastness of fabrics under sunlight climate includes a turntable and a driving mechanism for driving the turntable to rotate. There are several groups of clamping components for clamping textiles on the turntable. A plurality of clamping blocks evenly distributed in the circumferential direction are fixedly arranged on the circumferential wall of the turntable. An insertion gap is formed between the clamping block and the circumferential wall of the turntable. The clamping component is provided with an insertion plate inserted into the insertion gap. One side wall of the insertion gap is provided with a positioning hole arranged along the radial direction of the turntable. A positioning ball is arranged in the positioning hole. A plugging nut is arranged on the side of the positioning hole far away from the insertion gap. A compression spring is arranged between the plugging nut and the positioning ball. A clamping hole is arranged on the insertion plate. When the clamping component is installed on the turntable, the positioning ball is clamped into the clamping hole.

[0008] Furthermore, the cross section of the turntable is a regular polygon. A positioning end face is arranged on the side wall of the turntable. The cross section of the clamping block is a horizontal T shape. The clamping block is provided with a fitting end face and a clamping end face. When the clamping block is installed, the fitting end face fits with the positioning end face.

[0009] Further, a guiding inclined surface is provided at the top of the clamping end surface and is inclined.

[0010] Further, it includes a frame support fixedly installed on the chassis. A light filter cover coinciding with the axis of the turntable is installed on the frame support, and a xenon arc lamp is installed inside the light filter cover.

[0011] Further, it also includes a deep groove ball bearing. The inner ring of the deep groove ball bearing is fixedly connected to the outer wall of the frame support, and the outer ring of the deep groove ball bearing is fixedly connected to the turntable.

[0012] Further, the driving mechanism includes a motor, a first gear, and a ring gear seat. The ring gear seat is fixedly connected to the turntable, and the outer ring of the deep groove ball bearing is fixedly connected to the ring gear seat. The motor is fixedly installed on the chassis, the first gear is fixedly installed on the output shaft of the motor, and the first gear meshes with the ring gear on the ring gear seat.

[0013] Further, the driving mechanism also includes a first rotating shaft, a second rotating shaft, and a one-way bearing. The output shaft of the motor is fixedly connected to the first rotating shaft, the second rotating shaft is fixedly connected to the first gear, the inner ring of the one-way bearing is fixedly connected to the first rotating shaft, and the outer ring of the one-way bearing is fixedly connected to the second rotating shaft.

[0014] Further, the clamping assembly includes a pressure test clamp and symmetric shielding plate specimen pressing plates sequentially pressed on the pressure test clamp, and also includes a positioning mechanism for fixing the specimen pressing plate to the pressure test clamp.

[0015] Further, there are two groups of positioning mechanisms and they are respectively located at both ends of the specimen pressing plate. The positioning mechanism includes a threaded post and a clamping nut. The threaded post is fixedly installed on the pressure test clamp and is perpendicular to the pressure test clamp, and the clamping nut is threadedly connected to the threaded post.

[0016] Further, there are two groups of plug-in plates and they are installed on the pressure test clamp. On the pressure test clamp, a limiting edge is also provided on the side wall of the pressure test clamp, and the side walls of the symmetric shielding plate and the specimen pressing plate are abutted against the limiting edge.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model inserts the plug-in plate on the clamping assembly into the plug-in gap formed by the turntable and the clamping block to achieve the preliminary installation of the clamping assembly. Then, the compression spring is used to push the positioning ball to be clamped into the clamping hole, so that the plug-in plate abuts against the other side wall of the plug-in gap, thereby being able to limit the radial movement of the clamping assembly along the turntable.

Specific embodiments

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] This embodiment provides a clamping device for testing the color fastness of fabrics in sunlight climate, which is mainly used to improve the installation stability of the clamping assembly and prevent the textiles from shaking or falling off the turntable during the test.

[0028] As Figure 1 and Figure 2As shown in the figure, it includes a chassis 1. Inside the chassis 1, there is a test chamber 10. Inside the test chamber 10, there is a vertically arranged xenon arc lamp 6. A filter cover 5 is sleeved outside the xenon arc lamp 6. The wavelength of the light emitted by the xenon arc lamp 6 is filtered through the filter cover 5, so as to meet the benchmark requirements for fabric color fastness testing.

[0029] Specifically, in this embodiment, as Figure 1 and Figure 3 shown, a frame support 7 is fixedly installed on the bottom wall of the test chamber 10. The filter cover 5 is located on the frame support 7, and the xenon arc lamp 6 extends into the inner cavity of the filter cover 5. It should be noted here that the filter cover 5 is cylindrical.

[0030] In order to enable textiles to uniformly receive the light emitted by the xenon arc lamp 6, in this embodiment, as Figure 3 shown, the outer wall of the frame support 7 is connected with a turntable 3 through a deep groove ball bearing 8. Specifically, the inner ring of the deep groove ball bearing 8 is fixedly connected with the frame support 7, and the outer ring of the deep groove ball bearing 8 is fixedly connected with the turntable 3. As Figure 2 shown, it further includes a driving mechanism 2 for driving the turntable 3 to rotate. The textile is clamped by a clamping assembly 4. Then the clamping assembly 4 is inserted into the turntable 3, and the textile faces the xenon arc lamp 6.

[0031] Specifically, in order to clamp the textile, in this embodiment, as Figure 6 shown, the clamping assembly 4 includes a pressure test clamp 41, symmetric shields 42, a specimen pressing plate 43, and a positioning mechanism for fixing the specimen pressing plate 43 on the pressure test clamp 41. Specifically, when installing the textile, the textile is placed on the pressure test clamp 41, and then the symmetric shields 42 are pressed on the textile. At this time, the symmetric shields 42 partially block the textile, and the other part is exposed to contact the light of the xenon arc lamp 6. Then the specimen pressing plate 43 is pressed on the symmetric shields 42, and finally the specimen pressing plate 43 is fixed by the positioning mechanism, thus realizing the installation of the textile.

[0032] As Figure 7 shown, the specimen pressing plate 43 is in the shape of a frame and is pressed on the outside of the symmetric shields 42 so that the light of the xenon arc lamp 6 can irradiate the textile.

[0033] Specifically, in order to fix the specimen pressing plate 43, in this embodiment, as Figure 6 and Figure 7 shown, there are two groups of positioning mechanisms and they are respectively located on both sides of the specimen pressing plate 43. The positioning mechanism includes a threaded column 412 and a clamping nut 44. The threaded column 412 is fixedly installed on the pressure test clamp 41, and the threaded column 412 is perpendicular to the surface of the pressure test clamp 41. The clamping nut 44 is threadedly connected with the threaded column 412.

[0034] During the installation process, the clamping nut 44 is screwed out from the threaded post 412, so that there is a gap between the clamping nut 44 and the pressure test clamp 41 for installing the textile, the symmetric baffle 42 and the specimen pressing plate 43. Then, the textile, the symmetric baffle 42 and the specimen pressing plate 43 are placed on the pressure test clamp 41 in sequence. Finally, the clamping nut 44 is tightened, so that the end wall of the clamping nut 44 abuts against the end wall of the specimen pressing plate 43, thereby being able to fix the textile and the specimen pressing plate 43.

[0035] In order to make the placement position of the textile more accurate, in this embodiment, as Figure 6 and Figure 7 shown, one side edge of the pressure test clamp 41 is bent to form a limiting edge 411. Among them, the limiting edge 411 is perpendicular to the textile placement surface. During the placement process of the textile, the side edge of the textile is abutted against the limiting edge 411, thereby realizing the accurate placement of the textile. During this process, the side edges of the symmetric baffle 42 and the specimen pressing plate 43 can both be abutted against the limiting edge 411, so as to align the textile, the symmetric baffle 42 and the specimen pressing plate 43.

[0036] Since the specimen pressing plate 43 is in a frame shape, under normal circumstances, the specimen pressing plate 43 is prone to deformation. Therefore, in this embodiment, as Figure 6 and Figure 7 shown, bent edges 431 are bent out on both side edges of the specimen pressing plate 43, so as to enhance the strength of the specimen pressing plate 43 and reduce the risk of deformation of the specimen pressing plate 43.

[0037] In order to install the clamping assembly 4 on the turntable 3, in this embodiment, as Figure 4 shown, the cross section of the turntable 3 is a regular polygon. Specifically, the turntable 3 is a regular dodecagonal prism. Among them, a positioning end face 31 is formed on the side edge of the turntable 3, and a clamping block 32 is fixedly installed on the side wall of the positioning end face 31 through bolts. Among them, the clamping block 32 includes a fitting end face 321 that fits with the positioning end face 31, and clamping end faces 322 are provided on both sides of the fitting end face 321. When the clamping block 32 is installed, the fitting end face 321 abuts against the positioning end face 31, and a gap for inserting the clamping assembly 4 is formed between the clamping end faces 322 and the positioning end face 31.

[0038] Here, the gap between the clamping end faces 322 and the positioning end face 31 is defined as an insertion gap.

[0039] In order to facilitate the insertion of the clamping assembly 4 into the insertion gap, in this embodiment, as Figure 6 and Figure 7As shown, two plug-in plates 413 are provided on the pressure test clamp 41 and are respectively inserted into the plug-in gap. A U-shaped avoidance opening 414 is formed between the two plug-in plates 413. When the clamping assembly 4 is installed, the plug-in plates 413 can be inserted into the plug-in gap.

[0040] It should be noted here that the cross-section of the clamping block 32 is in a horizontally placed T shape. When the clamping block 32 is installed on the positioning end face 31, the cross-section at this time is in an H shape. Among them, the setting of the avoidance opening 414 is used to straddle the position where the fitting end face 321 fits with the positioning end face 31, thereby improving the installation stability of the clamping assembly 4.

[0041] It should be noted here that the pressure test clamp 41 is a sheet metal part, and the thickness of the pressure test clamp 41 is small. In order to improve the stability of the clamping assembly 4 as much as possible, the plug-in gap is slightly larger than the thickness of the pressure test clamp 41 at this time, so that the pressure test clamp 41 and the plug-in gap are in an interference fit.

[0042] Since the plug-in gap is small, it will cause the pressure test clamp 41 to be inconvenient to install. Therefore, in this embodiment, as Figure 4 and Figure 5 shown, the top of the clamping end face 322 is provided with an inclined guiding slope 323. Among them, the setting of the guiding slope 323 enlarges the opening for the plug-in plate 413 to be inserted. When the plug-in plate 413 is installed, the plug-in plate 413 first abuts against the guiding slope 323 at this time, and then the plug-in plate 413 is guided into the plug-in gap, thereby facilitating the installation of the plug-in plate 413.

[0043] Since the plug-in plate 413 and the plug-in gap are in an interference fit, the clamping assembly 4 will still shake along the radial direction of the turntable 3 at this time. Therefore, in this embodiment, as Figure 5 shown, the turntable 3 is provided with a positioning hole 311 penetrating the positioning end face 31. A positioning ball 312 is arranged in the positioning hole 311. A plugging nut 313 is arranged at one end of the positioning hole 311 away from the plug-in gap. A compression spring 314 is arranged between the plugging nut 313 and the positioning ball 312. The plug-in plate 413 is provided with a clamping hole 4131 aligned with the positioning hole 311. Among them, the aperture of the clamping hole 4131 is smaller than the diameter of the positioning ball 312.

[0044] Through the above settings, as Figure 5 shown, when the plug-in plate 413 is inserted into the plug-in gap, the compression spring 314 pushes the positioning ball 312 to cooperate with the clamping hole 4131 at this time, and then abuts one side wall of the plug-in plate 413 and the plug-in gap, thereby strengthening the stability of the clamping assembly 4. Since the positioning ball 312 can be inserted into the clamping hole 4131, the positioning ball 312 can also limit the tangential movement of the clamping assembly 4 along the turntable 3 at this time, further improving the stability of the clamping assembly 4.

[0045] When the clamping assembly 4 is removed from the turntable 3, it only needs to be moved vertically upward. At this time, the plug-in board 413 abuts against the spherical surface of the positioning ball 312, thereby pushing the positioning ball 312 into the positioning hole 311 and compressing the compression spring 314. After the plug-in board 413 is removed from the plug-in gap, the positioning ball 312 will return to the plug-in gap under the thrust of the compression spring 314.

[0046] In order to enable the rotation of the turntable 3, in this embodiment, as Figure 2 and Figure 3 shown, a ring gear seat 24 is fixedly installed on the turntable 3 through bolts. Among them, the outer ring of the deep groove ball bearing 8 is fixedly connected to the ring gear seat 24. The driving mechanism 2 further includes a motor 21 and a first gear 23. The motor 21 is fixedly installed in the chassis 1, the first gear 23 is fixedly connected to the output shaft of the motor 21, and the first gear 23 meshes with the ring gear on the ring gear seat 24.

[0047] Through the above settings, the power of the motor 21 is transmitted to the ring gear seat 24 through the first gear 23, and then the turntable 3 can be driven to rotate, so that the textile on the clamping assembly 4 can rotate around the xenon arc lamp 6.

[0048] Specifically, in this embodiment, as Figure 1 shown, a positioning plate 11 is provided in the chassis 1. Among them, the motor 21 is fixedly installed on the positioning plate 11.

[0049] Since the turntable 3 is installed in the test chamber 10, the motor 21 in the present invention has a self-locking function, and the test chamber 10 is relatively narrow, making it inconvenient to install the clamping assembly 4 on the turntable 3. Therefore, in this embodiment, as Figure 2 and Figure 3 shown, a first rotating shaft 201 is fixedly connected to the output shaft of the motor 21, a second rotating shaft 202 is fixedly connected to the first gear 23, and the first rotating shaft 201 and the second rotating shaft 202 are connected by a one-way bearing 22. Among them, the first rotating shaft 201 is fixedly connected to the inner ring of the one-way bearing 22, and the second rotating shaft 202 is fixedly connected to the outer ring of the one-way bearing 22.

[0050] Specifically, the model of the one-way bearing 22 is CK-A1542.

[0051] Through the above settings, when the clamping assembly 4 is installed, the position of the turntable 3 can be switched by rotating the turntable 3, so as to facilitate the installation of the clamping assembly 4.

[0052] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
