[0047] The specific style of the first driver 4 is not particularly limited, and the first driver 4 may be a cylinder, an oil cylinder, or a motor. Figures 1 to 4 In this embodiment, the first driver 4 is a cylinder, and the following description will be made by taking the first driver 4 as a cylinder as an example.

[0048] The first driver 4 is usually located on one side of the first clamp 2 in the lateral direction. The first driver 4 may be located on the side of the first clamp 2 in the lateral direction close to the second clamp 5, or the first driver 4 may be located on the side of the first clamp 2 in the lateral direction away from the second clamp 5. Figures 1 to 4 In this embodiment, the first driver 4 is located on a side of the first chuck 2 that is close to the second chuck 5 in the lateral direction.

[0049] Specifically, the first driver 4 is arranged on the base 1 through an L-shaped bracket, the first driver 4 is arranged in the horizontal direction, and the piston rod of the first driver 4 faces the first chuck 2. A cylinder connection block is arranged on the upper plate surface of the first horizontal plate of the first chuck 2, and the first horizontal plate is connected to the piston rod of the first driver 4 through the cylinder connection block.

[0050] See also Figures 1 to 4 The second clamp 5 is arranged on the base 1, and is provided with a second clamp 6 which can rotate along a lateral axis. The second clamp 6 is used to abut against a side of the product which is laterally away from the first clamp 3, so as to clamp the product through the second clamp 6 and the first clamp 3.

[0052] When the operator drives the first chuck 2 toward the second chuck 5 through the first driver 4, the first clamping member 3 on the first chuck 2 and the second clamping member 6 on the second chuck 5 can respectively abut against the two sides of the product to be inspected in the lateral direction, so that the product to be inspected can be quickly clamped and fixed by the first clamping member 3 and the second clamping member 6, and because the first clamping member 3 and the second clamping member 6 can be rotated, the operator can rotate the fixed product 360° to conduct a comprehensive inspection of the product appearance.

[0053] The second clamp 5 and the first clamp 2 are usually arranged opposite to each other in a spaced relationship in the transverse direction, wherein the second clamp 5 can be fixedly arranged on the base 1, or can be slidably arranged on the base 1 in the transverse direction. Figures 1 to 4 In this embodiment, the second chuck 5 is slidably disposed on the base 1 in a transverse direction. The appearance inspection jig 100 also includes a second driver 7, which is disposed on the base 1. The second driver 7 is power-coupled with the second chuck 5 to drive the second chuck 5 to slide in a transverse direction through the second driver 7.

[0054] Specifically, the second chuck 5 can slide back and forth along the horizontal direction (i.e., the length direction of the base 1) relative to the base 1, and the second driver 7, as the power source of the second chuck 5, can drive the second chuck 5 to automatically slide back and forth along the horizontal direction on the base 1 through the second driver 7. By synchronously driving the first chuck 2 and the second chuck 5 to move closer to each other through the first driver 4 and the second driver 7, the clamping speed of the product on the appearance inspection jig 100 can be further accelerated.

[0055] Optionally, see Figures 1 to 4 In this embodiment, a second linear guide rail 12 arranged in a transverse direction is provided between the second chuck 5 and the base 1. The second linear guide rail 12 can play a role of sliding guide for the second chuck 5, which is conducive to the smooth sliding of the second chuck 5 on the base 1.

[0056] The specific style of the second clamp 5 is not particularly limited. Figures 1 to 4 In this embodiment, the second chuck 5 is an L-shaped chuck, the lower end of the second chuck 5 is connected to the second driver 7 , and the second clamping member 6 is arranged at the upper end of the second chuck 5 .

[0057] Specifically, the second chuck 5 is arranged in an L-shape as a whole, and the second chuck 5 includes a second horizontal plate and a second vertical plate. A second linear guide rail 12 is arranged between the lower plate surface of the second horizontal plate and the base 1, so that the second horizontal plate can slide laterally relative to the base 1. The lower end of the second vertical plate is connected to an end of the second horizontal plate which is laterally away from the first chuck 2, and the second clamping member 6 is arranged at the upper end of the second vertical plate.

[0058] Similarly, the specific style of the second driver 7 is not particularly limited, and the second driver 7 may be a cylinder, an oil cylinder, or a motor. Figures 1 to 4 In this embodiment, the second driver 7 is a cylinder, and the following will take the second driver 7 as an example of a cylinder for introduction.

[0059] The second driver 7 is usually located on one side of the second clamp 5 in the lateral direction. The second driver 7 can be located on the side of the second clamp 5 in the lateral direction close to the first clamp 2, or on the side of the second clamp 5 in the lateral direction away from the first clamp 2. Figures 1 to 4 In this embodiment, the second driver 7 is located on a side of the second chuck 5 that is close to the first chuck 2 in the lateral direction.

[0060] Specifically, the second driver 7 is arranged on the base 1 through an L-shaped bracket, the second driver 7 is arranged in the horizontal direction, and the piston rod of the second driver 7 faces the second chuck 5. A cylinder connection block is arranged on the upper plate surface of the second horizontal plate of the second chuck 5, and the second horizontal plate is connected to the piston rod of the second driver 7 through the cylinder connection block.

[0061] The utility model drives the first chuck 2 toward the second chuck 5 through the first driver 4, so that the product to be inspected can be quickly clamped and fixed by the first clamping member 3 and the second clamping member 6, and because the first clamping member 3 and the second clamping member 6 can be rotated, the operator can rotate the fixed product 360° to conduct a comprehensive inspection of the product appearance. The appearance inspection fixture 100 can realize 360° inspection of product appearance, thereby improving production efficiency. The appearance inspection fixture 100 has the advantages of simple operation, convenient product inspection, and time and labor saving.

[0062] The base 1 is provided with a first chuck 2, a first driver 4, a second chuck 5, and a second driver 7, and the first chuck 2, the first driver 4, the second chuck 5, and the second driver 7 are usually arranged in a horizontal direction. Figures 1 to 4 In this embodiment, the first chuck 2, the first driver 4, the second driver 7, and the second chuck 5 are sequentially arranged on the base 1 along the horizontal direction. Such an arrangement can make the overall structure of the appearance inspection fixture 100 more compact.

[0063] The first clamping member 3 and the second clamping member 6 are respectively in contact with the two sides of the product in the horizontal direction. The first clamping member 3 can be located on the upper side or the lower side of the second clamping member 6. The first clamping member 3 can also be arranged flush with the second clamping member 6 in the vertical direction. Figures 1 to 4 In this embodiment, the first clamping member 3 and the second clamping member 6 are arranged flush with each other vertically and upwardly.

[0064] Specifically, the first clamping member 3 and the second clamping member 6 are flush with each other, that is, the rotation axis of the first clamping member 3 coincides with the rotation axis of the second clamping member 6. This allows the force on the product to be more balanced, so that the product can be clamped more stably by the first clamping member 3 and the second clamping member 6.

[0065] Optionally, see Figures 1 to 4 In this embodiment, the first clamping member 3 is elastically telescopically slidable relative to the first clamping head 2 in the lateral direction.

[0066] Specifically, since the first clamping member 3 can elastically expand and contract relative to the first clamping head 2, the abutment between the first clamping member 3 and the product is an elastic abutment, which is conducive to the first clamping member 3 being able to better abut the product.

[0067] For further information, see Figures 1 to 4In the present embodiment, the first clamping member 3 is arranged to extend in the transverse direction, and one end of the first clamping member 3 which is laterally away from the second clamping member 6 is rotatably and slidably arranged on the first chuck 2.

[0069] Optionally, see Figures 1 to 4 In this embodiment, a first groove 32 is provided on the end surface of the first clamping member 3 close to the second clamping member 6 .

[0070] Specifically, the first groove 32 is usually located in the middle of the end surface of the first clamping member 3 close to the second clamping member 6. The setting of the first groove 32 can reduce the contact area between the first clamping member 3 and the product, which is beneficial to ensure that the first clamping member 3 only applies lateral clamping force to the product.

[0071] Likewise, see Figures 1 to 4 In this embodiment, a second groove 61 is provided on the end surface of the second clamping member 6 close to the first clamping member 3 .

[0072] Specifically, the second groove 61 is usually located in the middle of the end surface of the second clamping member 6 close to the first clamping member 3. The setting of the second groove 61 can reduce the contact area between the second clamping member 6 and the product, which is conducive to ensuring that the second clamping member 6 only applies lateral clamping force to the product.

[0073] Optionally, see Figures 1 to 4 In this embodiment, the second clamping member 6 is arranged to extend in the transverse direction, and one end of the second clamping member 6 which is away from the first clamping member 3 in the transverse direction is arranged on the second clamping head 5 through a bearing 51.
