Description

Technical Field

[0001] This utility model relates to the field of parts inspection and clamping fixtures, and in particular to a parts clamping fixture for batch inspection of optical imaging instruments. Background Technology

[0002] Part inspection clamping fixtures are key tools used to accurately fix and position parts during the part inspection process. They are widely used in many industries with extremely high precision requirements for parts, such as machinery manufacturing, automobile production, and aerospace. Part inspection clamping fixtures not only improve the efficiency and accuracy of part inspection, but also reduce human operation errors, providing strong support for product quality control and helping enterprises improve production efficiency and reduce production costs.

[0003] Existing technologies, such as the utility model with publication number CN215148435U, disclose a part clamping fixture for batch inspection by an optical imager. This patent uses an optical imager and a clamping assembly. The optical imager is equipped with a worktable for inspection. The top left and right sides of the worktable are equipped with moving components for moving the clamping assembly. The top of the moving components is equipped with a clamping assembly for fixing the parts. This solves the problem that the existing conventional measurement method involves placing individual parts on the measurement platform for clamping and measurement one by one, which is not convenient for the quick fixing and disassembly of parts, and seriously affects the inspection efficiency of parts.

[0004] When using clamping fixtures to hold parts for inspection, existing clamping fixtures, such as those mentioned above, can quickly clamp and lock parts, but after the inspection is completed, the user still needs to manually unlock the clamping structure. Furthermore, since the clamping structure is divided into left and right groups, the user needs to spend a certain amount of time unlocking, which increases the time cycle for batch inspection. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that after the parts are inspected, the user still needs to manually unlock the clamping structure, and because the clamping structure is divided into left and right groups, the user needs to spend a certain amount of time to unlock it, which increases the time cycle during batch inspection. Therefore, a parts clamping fixture for batch inspection of optical imaging instruments is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamping fixture for batch inspection of parts for optical imaging instruments, comprising an operating table, a bracket fixedly connected to the upper surface of the operating table, an industrial camera mounted on the lower surface of the bracket, an auxiliary component provided on the upper surface of the operating table, the auxiliary component including a guide rail, the guide rail fixedly connected to the upper surface of the operating table, an installation cavity formed on the upper surface of the guide rail, a connecting plate slidably connected to the guide rail on the inner wall of the installation cavity, a limit spring fixedly connected to the lower surface of the connecting plate, the end of the limit spring away from the connecting plate being fixedly connected to the inner wall of the installation cavity, a protrusion fixedly connected to the upper surface of the connecting plate, a connecting frame slidably connected to the surface of the guide rail, a limit frame fixedly connected to the upper surface of the connecting frame, and a fixing hole formed on the upper surface of the connecting frame;

[0007] The auxiliary component also includes a load-bearing plate. The inner side wall of the limiting frame has a storage cavity. The load-bearing plate is slidably connected to the inner wall of the storage cavity. A constraint spring is fixedly connected to the side surface of the load-bearing plate. The end of the constraint spring away from the load-bearing plate is fixedly connected to the inner wall of the storage cavity. A connecting rod is fixedly connected to the side of the load-bearing plate away from the constraint spring. A clamping plate is fixedly connected to the end of the connecting rod away from the load-bearing plate.

[0008] Preferably, a linkage plate is fixedly connected to the side surface of the connecting frame, and the two connecting frames can be connected through the linkage plate, so that the two connecting frames can move synchronously.

[0009] Preferably, a rubber strip is fixedly connected to the side of the clamp away from the connecting rod. The upper surface of the rubber strip is provided with rounded corners. The rubber strip can increase the friction between the clamp and the part, thereby improving the stability of the clamp when holding the part.

[0010] Preferably, the protrusion is slidably connected to the inner wall of the mounting cavity, the protrusion is inserted into the inner wall of the fixing hole, the height of the protrusion is higher than the upper surface of the connecting frame, and the upper end of the protrusion is hemispherical. The protrusion can lock the position of the connecting frame with the fixing hole, and at the same time, push the parts placed on the connecting frame out of the clamping area, so as to facilitate the user to pick up the parts that have been tested.

[0011] Preferably, there are two connecting frames, which are horizontally distributed with reference to the guide rail. The number of limiting frames is adapted to the number of connecting frames. The position of the parts can be constrained by the limiting frames, which can ensure that the parts are placed in the designated area.

[0012] Preferably, there are multiple constraint springs, which are longitudinally distributed with reference to the load-bearing plate. The constraint springs can constrain the position of the load-bearing plate to ensure its stability during use.

[0013] Preferably, the connecting rod is slidably connected to the inner wall of the receiving cavity. The connecting rod can connect the load plate and the clamping plate, so that when the constraint spring constrains the load plate, it can apply a certain pressure to the clamping plate, thereby ensuring the stability of the clamping plate when clamping the workpiece.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, by setting auxiliary components, users can push the clamping structure to eject the part from the clamping area after completing the part inspection. This ensures convenient clamping and improves the efficiency of subsequent part retrieval. It also reduces the problem of limiting the inspection efficiency of the equipment by having to unlock the left and right clamping structures separately when retrieving parts, and further improves the efficiency of the clamping fixture.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a clamping fixture for batch inspection of parts for optical imaging instruments, including an operating table 1, a bracket 2 fixedly connected to the upper surface of the operating table 1, an industrial camera 3 mounted on the lower surface of the bracket 2, and an auxiliary component 4 provided on the upper surface of the operating table 1.

[0023] In this embodiment: the auxiliary component 4 includes a guide rail 41, which is fixedly connected to the upper surface of the operating table 1. The upper surface of the guide rail 41 has an installation cavity 42. The guide rail 41 is slidably connected to the inner wall of the installation cavity 42. The lower surface of the connecting plate 43 is fixedly connected to a limit spring 44. The end of the limit spring 44 away from the connecting plate 43 is fixedly connected to the inner wall of the installation cavity 42. The upper surface of the connecting plate 43 is fixedly connected to a protrusion 45. The surface of the guide rail 41 is slidably connected to a connecting frame 46. The upper surface of the connecting frame 46 is fixedly connected to a limit frame 47. The upper surface of the connecting frame 46 has a fixing hole 48.

[0024] The auxiliary component 4 also includes a load-bearing plate 411. A storage cavity 410 is provided on the inner side wall of the limiting frame 47. The load-bearing plate 411 is slidably connected to the inner wall of the storage cavity 410. A constraint spring 412 is fixedly connected to the side surface of the load-bearing plate 411. The end of the constraint spring 412 away from the load-bearing plate 411 is fixedly connected to the inner wall of the storage cavity 410. A connecting rod 413 is fixedly connected to the side of the load-bearing plate 411 away from the constraint spring 412. A clamping plate 414 is fixedly connected to the end of the connecting rod 413 away from the load-bearing plate 411.

[0025] Specifically, a linkage plate 49 is fixedly connected to the side surface of the connecting frame 46. The two connecting frames 46 can be connected through the linkage plate 49, so that the two connecting frames 46 can move synchronously.

[0026] Specifically, a rubber strip 415 is fixedly connected to the side of the clamping plate 414 away from the connecting rod 413, and the upper surface of the rubber strip 415 is provided with rounded corners.

[0027] In this embodiment, the rubber strip 415 can increase the friction between the clamping plate 414 and the part, thereby improving the stability of the clamping plate 414 when holding the part.

[0028] Specifically, the protrusion 45 is slidably connected to the inner wall of the mounting cavity 42, and the protrusion 45 is inserted into the inner wall of the fixing hole 48. The height of the protrusion 45 is higher than the upper surface of the connecting frame 46, and the upper end of the protrusion 45 is hemispherical. The protrusion 45 can lock the position of the connecting frame 46 with the fixing hole 48, and can push the parts placed on the connecting frame 46 out of the clamping area, so as to facilitate the user to pick up the parts that have been tested.

[0029] In this embodiment, there are two connecting frames 46, which are horizontally distributed with reference to the guide rail 41, and the number of limiting frames 47 is adapted to the number of connecting frames 46.

[0030] In this embodiment, the position of the part can be constrained by the limiting frame 47, which can ensure that the part is placed in the specified area.

[0031] Specifically, there are multiple constraint springs 412, which are longitudinally distributed with reference to the load plate 411. The position of the load plate 411 can be constrained by the constraint springs 412 to ensure the stability of the load plate 411 during use.

[0032] Specifically, the connecting rod 413 is slidably connected to the inner wall of the storage cavity 410.

[0033] In this embodiment, the load-bearing plate 411 and the clamping plate 414 can be connected by the connecting rod 413, so that the constraint spring 412 can apply a certain pressure to the clamping plate 414 when constraining the load-bearing plate 411, thereby ensuring the stability of the clamping plate 414 when clamping the workpiece.

[0034] Working principle: When inspecting parts, the industrial camera 3 is connected to the host. After being connected to the host, the industrial camera 3 can compare the inspected parts with the data in the host, thereby removing defective parts.

[0035] When inspecting a part, the part is placed in the limiting frame 47 below the industrial camera 3. During the placement of the part, the part comes into contact with the rubber strips 415 on both sides and the rubber strips 415 press the clamping plate 414. The clamping plate 414, under the force of the connecting rod 413, pushes the load plate 411. The load plate 411, under the force of the connecting rod 413, presses the constraint spring 412. The constraint spring 412 is deformed by the compression. When the part comes into contact with the upper surface of the connecting frame 46, the part stops applying force to the rubber strips 415. At the same time, the clamping plate 414 stops pushing the connecting rod 413. The connecting rod 413 and the load plate 411 stop pressing the limiting spring 44. The limiting spring 44 stops deforming and provides a continuous pushing force to the load plate 411. Under the action of the limiting spring 44, the load plate 411, in conjunction with the connecting rod 413, applies a pushing force to the clamping plate 414 and the rubber strips 415, so that the clamping plate 414 and the rubber strips 415 continuously and stably clamp the inspected part.

[0036] After the part inspection is completed, the connecting frame 46 is pushed towards the direction without a workstation. Guided by the guide rail 41, the connecting frame 46 pushes the limiting frame 47. The limiting frame 47 moves the part below the industrial camera 3. During the movement, the connecting frame 46 presses against the protrusion 45. The protrusion 45 is under force and, together with the connecting plate 43, presses against the limiting spring 44. The limiting spring 44 is deformed by compression. When the connecting frame 46 with the part placed on it moves above the protrusion 45 and the protrusion 45 coincides with the fixing hole 48, the protrusion 45 loses the pressure applied by the connecting frame 46. At the same time, the connecting plate 43 loses the pressure applied to the limiting spring 44, and the limiting spring 44 loses its function. The pressure is released and the springback pushes the connecting plate 43 and the protrusion 45 to reset. During the reset process, the protrusion 45 inserts into the fixing hole 48 and penetrates the upper surface of the connecting frame 46, lifting the parts in the clamping area upwards so that the parts are released from the clamping state. During the process of the parts being released from the clamping state, the other idle clamping area moves to below the industrial camera 3. Then, the user can place another part into the clamping area below the industrial camera 3 according to the steps in the above operation. After the placement is completed and the industrial camera 3 is performing inspection, the user can put away the parts that have been released from the clamping state. Then, the user can repeat the above operation to achieve batch inspection of parts.

[0037] By setting up auxiliary component 4, users can push the clamping structure to push the part out of the clamping area after completing the part inspection. This ensures convenient clamping and improves the efficiency of subsequent part retrieval. It also reduces the problem of limiting the inspection efficiency of the equipment by having to unlock the left and right clamping structures separately when retrieving parts, and further improves the utilization efficiency of the clamping fixture.
