Description

Technical Field

[0001] The utility model relates to the technical field of paint sample preparation equipment, in particular to a paint sample clamping device and a paint clamping device. Background Art

[0002] In the process of paint research and development, it is inevitable to use tinplate and other samples for paint sample preparation and testing of the comprehensive performance of the paint. However, when using spray equipment to spray the sample, due to the small size and limited weight of the sample, it is easy to cause the sample to shift at the beginning of spraying. In severe cases, it will cause the sample to overturn, resulting in the scrapping of the sample, wasting the sample and increasing the sample preparation time. For this reason, the sample needs to be temporarily fixed, and after spraying, the sample needs to be disassembled and sent to a constant temperature oven for drying. At present, there are three common practices for spraying samples: 1. Drilling holes near the top of the sample for hanging the sample; 2. Using double-sided tape to fix the sample on a plane for spraying; 3. Using magnets to hold the sample under the sample.

[0003] However, all three methods mentioned above have certain drawbacks. For example, although the first method suspends the sample, it is still necessary to manually keep the sample fixed during the spraying process to prevent the sample from flipping over during spraying. In the second method, the hand will inevitably touch the sample when placing it, and the sample needs to be cleaned before spraying. After the spraying is completed, the sample is not easy to separate due to the strong viscosity of the double-sided adhesive. Excessive force will cause the sample to flip over, resulting in the sample being scrapped. The third method, although simple and convenient for sampling, cannot be used for non-iron-based samples, and the magnet is easily lost.

[0004] In addition, no matter which of the above-mentioned existing sample fixing methods is used, after the sample is sprayed, it is necessary to take samples one by one and send them into the oven for constant temperature drying. The process of transferring the samples one by one into the oven is not only inefficient, but also the operator is likely to touch the sprayed surface of the sample and contaminate the sample. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent: to provide a paint sample clamping device and a paint clamping equipment, which can clamp samples of various shapes made of various materials, improve the versatility of the samples, reduce the operators' touching of the samples, and improve the sample preparation efficiency.

[0006] For this reason, an object of the present utility model is to provide a coating sample clamping device, which includes a base. A clamping mechanism is provided on the base, and a clamping space for accommodating the sample is provided on the clamping mechanism. The clamping mechanism includes at least three clamping arms arranged circumferentially along the clamping space for clamping the sample. Each clamping arm includes a vertical rod and a horizontal rod. One end of the horizontal rod is connected to the lower end of the vertical rod. Slots for inserting the ends of the horizontal rods are provided at positions corresponding to the respective horizontal rods on the base. A fixing member is provided in the slot, and the end of the horizontal rod located in the slot is connected to the fixing member through a telescopic member, so that the horizontal rod is in sliding fit with the slot.

[0007] The above technical solution has the following advantages or beneficial effects: First, the sample is clamped by multiple clamping arms and thus suspended above the base. Therefore, if it is necessary to remove the sample after spraying is completed, only the clamping arms need to be pulled against the acting force of the telescopic member to remove the sample, and the sampling process is convenient and labor-saving; if the size of the oven is sufficient, the base together with the sample on the base can be placed in the oven, and this process reduces the process of disassembling the sample, so the possibility of the operator accidentally touching the sample caused by sample disassembly is reduced.

[0008] According to an example of the present utility model, a fixer detachably connected to the base is provided on the base, and the slot is provided on the fixer.

[0009] According to an example of the present utility model, the lower end of the vertical rod is inserted into the horizontal rod, and the vertical rod is rotationally engaged with the horizontal rod around its own axis. By the way that the vertical rod can rotate relative to the horizontal rod, the orientation of the clamping opening on the vertical rod can be changed, thereby realizing the clamping of samples of non-standard sizes.

[0010] According to an example of the present utility model, the clamping arms include at least two groups of clamping arms arranged at intervals along the width direction, and each group of clamping arms is composed of two clamping arms symmetrically arranged along the length direction.

[0011] According to an example of the present utility model, a clamping opening for clamping the sample is formed by horizontal internal tangency on the outer side wall of the vertical rod.

[0012] According to an example of the present utility model, the bottom surface of the clamping opening is in a horizontal state, the two side surfaces of the clamping opening are in a vertical state and the included angle α between them is 90° to 180°, and the clamping opening extends upward in the vertical direction to penetrate the top surface of the vertical rod.

[0013] According to an example of the present utility model, the included angle α between the two side surfaces of the clamping opening is 90°.

[0014] For this reason, an object of the present utility model is to provide a coating clamping device, which includes a sample table, and at least one of the above coating sample clamping devices is provided on the sample table.

[0015] According to an example of the present utility model, there are multiple coating sample clamping devices, and the multiple coating sample clamping devices are arranged at intervals in the horizontal direction.

[0016] The above technical solution has the following advantages or beneficial effects: First, samples of any material can be fixed by clamping and transferred to the oven with the base after spraying, eliminating the process of disassembling the samples, thus reducing the situation of operators accidentally touching the samples; Second, the clamping arms in the clamping mechanism can be arbitrarily replaced as needed, so as to be applicable to samples of different shapes. Especially when the vertical rod and the horizontal rod on the clamping arm are connected in a detachable and rotatable manner, the vertical rod on the clamping arm can better clamp samples of different shapes; Finally, multiple coating sample clamping devices can be arranged on the sample table at the same time, and each coating sample clamping device can clamp one sample. After all the samples are sprayed, the sample table and all the samples on the sample table can be transferred to the oven at one time, which has higher working efficiency compared with the way of transferring one by one.

[0017] The additional aspects and advantages of the present utility model will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present utility model. Description of the Drawings

[0028] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0029] The paint template clamping device according to an embodiment of the present utility model will be described in detail below with reference to the drawings.

[0030] The width direction referred to hereinafter means Figure 1 the left - right direction in Figure 1 and the length direction means

[0031] The present utility model provides a paint template clamping device. As shown in the figure, it includes a base 1. A clamping mechanism for clamping the template is provided on the base 1. The clamping mechanism clamps the template so that the template is suspended in the clamping space above the base. The clamping mechanism includes at least three clamping arms. The plurality of clamping arms are arranged at intervals in the circumferential direction of the clamping space where the template is located, so that when the template is placed in the clamping space, the template can be clamped by the clamping force formed by the relative movement of the plurality of clamping arms. Specifically, the clamping arm includes a vertical rod 3 and a horizontal rod 4. One end of the horizontal rod 4 is connected to the lower end of the vertical rod 3. Slots 6 for inserting the ends of the horizontal rods 4 are provided at the positions corresponding to the respective horizontal rods 4 on the base 1. Fixing members are provided in the slots 6. The end of the horizontal rod 4 located in the slot 6 is connected to the fixing member through a telescopic member 5, so that the horizontal rod 4 is in sliding fit with the slot 6. Preferably, the telescopic member 5 is a tension spring.

[0032] Based on the preference of the above - mentioned embodiment, the mounting component where the slot is located and the base 1 can be connected in a fixed manner, such as welding or bonding.

[0033] Based on the preference of the above - mentioned embodiment, as Figure 2As shown, a fixture 2 detachably connected to the base 1 is provided on the base 1, and the slot 6 is provided on the fixture 2. The base 1 has mounting holes or grooves, and the bottom of the fixture has mounting components matching the mounting holes or grooves, thereby realizing the detachable connection between the fixture and the base 1. Compared with fixed connection methods such as welding or bonding, the fixture 2 in this embodiment enables a detachable connection between the clamping mechanism and the base 1, and corresponding clamping arms can be replaced according to the actual process requirements, so as to facilitate the use of different clamping arms for different templates. Preferably, the mounting component at the bottom of the fixture is a stud with an external thread, and the mounting hole on the base 1 is a mounting hole with an internal thread, and the stud is threadedly connected to the mounting hole to fix the fixture to the base 1.

[0034] In the above embodiment, the vertical rod 3 and the horizontal rod 4 in the clamping arm are connected to form an L-shaped structure. One end of the horizontal rod 4 is connected to the lower end of the vertical rod 3, and the other end of the horizontal rod 4 is inserted into the slot 6 on the fixture 2. The telescopic member 5 is arranged in the slot 6, and both ends of the tension spring 5 are respectively connected to the horizontal rod 4 and the bottom of the slot 6. In this embodiment, the setting direction of the slot 6 is the movement direction of the horizontal rod 4. In order to realize clamping in the length direction, the fixture 2 is respectively provided with slots arranged along the length direction on both sides along the length direction. Preferably, a fixing member is provided in the slot 6, the fixing member is fixedly connected to the bottom of the slot, one end of the telescopic member is connected to the fixing member, and the other end is connected to one end of the horizontal rod 4 inserted into the slot 6.

[0035] The clamping arm includes at least two groups of clamping arms arranged at intervals in the width direction, and each group of clamping arms consists of two clamping arms symmetrically arranged in the length direction. Preferably, there are two groups of clamping arms in the clamping mechanism. Specifically, two groups of clamping arms with the same structure are arranged at intervals in the width direction. Each group of clamping arms includes two clamping arms symmetrically arranged in the length direction. A clamping space for clamping the template 8 is formed between the two clamping arms. The lower end of the clamping arm is slidably matched with the fixture 2 in the length direction, and the lower end of the clamping arm is connected to the telescopic member 5 in the slot on the fixture 2, so that the two clamping arms have a tendency of relative movement. In this embodiment, one template is placed on one fixture 2, and the template is clamped by multiple clamping arms in the clamping mechanism on the fixture 2 so that the template is fixed and suspended above the fixture 2. Preferably, the four clamping arms are distributed in a matrix.

[0036] In the above embodiment, in order to prevent the template from sliding in the height direction, the preference of this embodiment is that: a clamping opening 7 for clamping the template is formed by an internal tangent in the horizontal direction on the outer side wall of the vertical rod (3).

[0037] Preferably, as Figure 3 and Figure 4The clamping opening 7 is a triangular notch formed by an in - cut along the horizontal direction, and both sides of the triangular notch in the width direction extend through the outer wall of the vertical rod 3. In this embodiment, through the telescopic movement of the clamping arm along the length direction, different lengths of templates 8 can be correspondingly matched. There is no limit to the size of the template 8 in the width direction. During the actual sample - making process, the sample - making personnel can select a template 8 with an appropriate width in advance, that is, the width of the template 8 should be greater than the distance between adjacent pairs of clamping arms and slightly less than the width dimension of the base 1.

[0038] In the above - mentioned embodiment, the templates are mostly standard square templates, but in the actual sample - making process, there will be templates of other shapes, such as Figure 8 the shown triangle, as well as trapezoids, parallelograms, irregular shapes, etc. At this time, when using the above - mentioned clamping arms to clamp such non - standard templates, there will be a problem that the clamping opening 7 does not match the template 8, affecting the clamping effect. Therefore, the improvement of this embodiment is that the lower end of the vertical rod 3 is detachably connected to the cross - rod 4, and the vertical rod 3 is rotationally matched with the cross - rod 4 around its own axis. As Figure 8 shown, place each corner of the template 8 into its corresponding clamping opening 7. Through the rotation of the vertical rod 3, the clamping opening 7 can be arbitrarily adjusted in orientation according to the different corners of the template 8, thereby enabling the clamping of such non - square templates.

[0039] In this embodiment, through the rotation of the vertical rod 3, it is also applicable to square templates. As Figure 7 shown, the four corners of the square template are embedded into their corresponding clamping openings 7. By rotating the four vertical rods 3, the clamping openings 7 of each vertical rod 3 can be well aligned with the four corners of the square template. The advantage of this embodiment compared with the above - mentioned triangular clamping opening is that it not only limits the size of the template 8 in the length direction but also has a limiting effect on the size of the template 8 in the width direction. Thus, the template can be better fixed on the fixture 2, reducing the risk of the template sliding and shifting.

[0040] Based on the preference for the structure of the clamping opening 7 in the case where the vertical rod 3 is rotatable, as Figure 10 and Figure 11 shown, the bottom surface 7.1 of the clamping opening 7 is in a horizontal state, the two side surfaces 7.2 of the clamping opening 7 are in a vertical state and the intersecting angle α is 90° - 180°, and the clamping opening 7 extends upward in the vertical direction through the top surface of the vertical rod 3.

[0041] Preferably, the intersecting angle α of the two side surfaces 7.2 of the clamping opening 7 is 90°.

[0042] Based on the above - mentioned paint - sample clamping device in the embodiment, the present utility model provides a paint - clamping device, including a sample table 9, and at least one of the above - mentioned paint - sample clamping devices is provided on the sample table 9.

[0043] Preferably, there are a plurality of the coating sample clamping devices, and the plurality of coating sample clamping devices are arranged at intervals in the horizontal direction. Specifically, as Figure 1 shown, there are 9 coating sample clamping devices, and the 9 coating sample clamping devices are arranged in a matrix on the sample stage 9.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.

Therefore, the appended claims should be regarded as covering all changes and corrections that embody the true spirit and scope of the present invention. Any and all equivalent ranges and contents within the scope of the claims should be considered to still fall within the spirit and scope of the present invention.
