Description

Technical Field

[0001] This utility model relates to the field of aiming scope processing technology, and in particular to a positioning fixture for aiming scope processing. Background Technology

[0002] A sight is an optical component widely used in firearms, telescopes, and vehicle-mounted instruments. Its main function is to magnify the target, helping the user aim more accurately. It is widely used in shooting, hunting, navigation, and many other fields. A sight generally consists of an objective lens, an eyepiece, and a central mounting section. The objective and eyepiece are hollow structures. The central mounting section has four planes with mounting holes for installing adjusters, facilitating left-right and up-down position adjustments. During the manufacturing process of a sight, to ensure machining accuracy, positioning fixtures are typically used to position the sight to be processed, facilitating subsequent machining operations.

[0003] For example, Chinese utility model patent CN222360088U provides a positioning fixture for framing a scope, including a support frame. A heat sink is fixedly installed in the middle of the support frame, a first motor is fixedly installed at the bottom of the inner cavity of the heat sink, a fan blade is movably installed on the top of the first motor, and a filter is fixedly installed on the surface of the heat sink. The support frame allows the entire device to be lifted to a certain height for subsequent processing. The heat sink facilitates timely cooling of the completed scope components, thereby accelerating the processing speed and improving efficiency. The first motor drives the fan blade to rotate, drawing natural air to blow onto the completed scope components. The filter reduces the amount of contaminants entering the heat sink, thus minimizing their impact on the fan blade's rotation.

[0004] Although the aforementioned device can effectively cool down the processed scope, it lacks the capability to handle multiple angles during the processing of scopes to meet the needs of different procedures. This undoubtedly limits its versatility and flexibility in practical applications, thus presenting certain limitations. Utility Model Content

[0005] This utility model discloses a positioning fixture for the processing of a scope, which solves the problem that traditional positioning fixtures for the processing of scopes do not have the function of multi-angle processing and have limitations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A scope machining and positioning fixture includes a horizontally arranged worktable. A circular and horizontal turntable is rotatably connected to the top surface of the worktable. A first drive assembly is provided on the worktable to drive the turntable to rotate around its own axis. Two symmetrical and vertical support plates are fixed to the top surface of the turntable. A horizontal support shaft is fixed between the two support plates. A horizontal movable plate is sleeved on the support shaft. The support shaft is located at the central axis of the movable plate in the width direction and is perpendicular to the movable plate. A second drive assembly is provided on the turntable to drive the movable plate to rotate around the axis of the support shaft. The second drive assembly includes a semi-circular ring slidably connected to the center of the top surface of the turntable. The semi-circular ring has internal teeth with the side having internal teeth facing upwards. The two ends of the semi-circular ring are fixedly connected to the two sides of the bottom surface of the movable plate, respectively. A horizontal first motor is fixed to one of the support plates. A first gear that meshes with the internal teeth of the semi-circular ring is fixed to the output end of the first motor. A clamping assembly for holding the scope is provided on the movable plate, and a heat dissipation assembly is also provided on the movable plate.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The scope to be processed is placed on the movable plate and clamped in place using a clamping assembly. When it is necessary to change the vertical tilt angle of the scope, the first motor is activated. The output of the first motor drives the first gear to rotate around its own axis, which in turn drives the semi-circular ring to rotate through the meshing internal teeth. Since the two ends of the semi-circular ring are fixedly connected to the bottom sides of the movable plate, the movable plate can be driven to rotate around the axis of the support shaft, thus making the heights of the two sides of the movable plate inconsistent, thereby achieving the function of adjusting the tilt angle of the scope fixed on the movable plate. When it is necessary to change the horizontal rotation angle of the scope, the first drive assembly drives the turntable to rotate around its own axis, which can drive the entire scope to rotate horizontally. This can meet the needs of multi-angle processing. After the scope is processed, a heat dissipation assembly can be used to dissipate heat from the scope, so that it can be put into use as soon as possible. This invention boasts a high degree of automation and practicality. By incorporating a worktable, turntable, first drive assembly, support plate, support shaft, movable plate, semi-circular ring, internal gear, first motor, first gear, and clamping assembly, it not only enables the adjustment of the vertical tilt angle of the sight to be processed but also changes the horizontal rotation angle of the sight, effectively expanding the applicability of the entire device. Furthermore, it is equipped with a heat dissipation assembly to cool the sight, allowing it to be put into use as soon as possible. Attached Figure Description

[0017] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a positioning fixture for processing a sight, including a horizontally arranged worktable 1. A circular and horizontal turntable 2 is rotatably connected to the top surface of the worktable 1. The worktable 1 is provided with a first driving component for driving the turntable 2 to rotate around its own axis. Two symmetrical and vertical support plates 3 are fixed to the top surface of the turntable 2. A horizontal support shaft 31 is fixed between the two support plates 3. A horizontal movable plate 4 is sleeved on the support shaft 31. The support shaft 31 is located at the central axis in the width direction of the movable plate 4 and is perpendicular to the movable plate 4. The turntable 2 is provided with a... A second drive assembly is provided for rotating the movable plate 4 around the axis of the support shaft 31. The second drive assembly includes a semi-circular ring 5 slidably connected to the center of the top surface of the turntable 2. The semi-circular ring 5 has internal teeth 51 with the side having internal teeth 51 facing upward. The two ends of the semi-circular ring 5 are fixedly connected to the two sides of the bottom surface of the movable plate 4, respectively. A horizontal first motor 61 is fixed on one of the support plates 3. The output end of the first motor 61 is fixed with a first gear 6 that meshes with the internal teeth 51 of the semi-circular ring 5. The movable plate 4 is provided with a clamping assembly for clamping the scope and a heat dissipation assembly.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, the clamping assembly includes two sets of mounting brackets 7 symmetrically fixed on both sides of the movable plate 4. Each set of mounting brackets 7 consists of two symmetrical brackets, one in front and one behind. Each mounting bracket 7 has an arc-shaped and vertical clamping block 71 movably mounted on it. Each mounting bracket 7 also has an automatic push rod 72 for driving the corresponding clamping block 71 to move horizontally along the width direction of the movable plate 4. After the scope to be processed is placed horizontally on the top surface of the movable plate 4, the four automatic push rods 72 are activated. The output ends of the four automatic push rods 72 can drive the corresponding clamping block 71 to move horizontally along the width direction of the movable plate 4, so that all four clamping blocks 71 are in contact with the surface of the scope, thus clamping and fixing scopes of different sizes.

[0020] like Figure 3 As shown, each clamp 71 has a rubber layer 73 on the side not connected to the automatic push rod 72. The rubber layer 73 not only increases the friction between the clamp 71 and the scope to fix the scope more firmly, but also effectively prevents scratches on the surface of the scope from affecting product quality.

[0021] like Figure 2 As shown, the heat dissipation assembly includes several fans 41 rotatably connected within the movable plate 4. The bottom surface of the movable plate 4 has several ventilation holes corresponding to the fans 41. The movable plate 4 also has several sets of dust filters 42, with two filters in each set positioned above and below the corresponding fans 41. Furthermore, several micro motors (not shown) can be installed within the movable plate 4 to drive the rotation of the corresponding fans 41, thereby achieving heat dissipation for the scope placed on the top surface of the movable plate 4. The dust filters 42 prevent dust and other small particles from entering the fans 41, ensuring their continuous and stable operation, and also filter the airflow from the fans 41 to maintain the cleanliness of the scope. Moreover, each dust filter 42 can be detachably connected to the movable plate 4 using bolts, facilitating regular cleaning and replacement by personnel.

[0022] like Figure 1 and Figure 2 As shown, a power supply 9 is provided on the support plate 3. The power supply 9 is electrically connected to the fan 41, the first motor 61, and the automatic push rod 72 via wires. The power supply 9 is preferably a rechargeable power supply. By setting the power supply 9, the fan 41, the first motor 61, and the automatic push rod 72 can be continuously powered to prevent the wires from getting tangled during the rotation of the turntable 2.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, the first drive assembly includes a second motor 8 vertically fixed inside the worktable 1. The output end of the second motor 8 passes through the top surface of the worktable 1 and extends outside the worktable 1. A horizontal second gear 81 is fixed to the output end of the second motor 8, and a gear ring 21 meshing with the second gear 81 is fixed to the outer surface of the turntable 2. When the second motor 8 is started, its output end drives the second gear 81 to rotate around its own axis, which in turn drives the entire turntable 2 to rotate through the meshing gear ring 21, thereby changing the rotation angle of the sight in the horizontal direction. Furthermore, both the first motor 61 and the second motor 8 are stepper motors to achieve precise control of the sight's minute angle.

[0024] like Figure 1 , Figure 4 and Figure 6 As shown, a slide rail 52 is fixed to the outer edge of the semicircular ring 5, and a groove 22 corresponding to the slide rail 52 is formed at the center of the top surface of the turntable 2. The semicircular ring 5 and the turntable 2 are slidably connected by the slide rail 52 and the groove 22. The slide rail 52 and the groove 22 can limit and guide the semicircular ring 5 to prevent it from sliding off the turntable 2.

[0025] like Figure 1 As shown, several supports 11 are fixed to the bottom surface of the workbench 1. The supports 11 can fix and support the entire device.

[0026] In use, after placing the scope to be processed horizontally on the top surface of the movable plate 4, activate the four automatic push rods 72. The output ends of the four automatic push rods 72 can drive the corresponding clamping blocks 71 to move horizontally along the width direction of the movable plate 4, so that the four clamping blocks 71 are in contact with the surface of the scope, thus clamping and fixing scopes of different sizes. When it is necessary to change the tilt angle of the scope in the vertical direction, activate the first motor 61. The output end of the first motor 61 drives the first gear 6 to rotate around its own axis, which can drive the semi-circular ring 5 to rotate through the meshing internal teeth 51. Since the two ends of the semi-circular ring 5 are fixedly connected to the two sides of the bottom surface of the movable plate 4 respectively. Then, the movable plate 4 can be driven to rotate around the axis of the support shaft 31, thereby making the heights of the two sides of the movable plate 4 inconsistent, thus realizing the function of adjusting the tilt angle of the sight fixed on the movable plate 4; when it is necessary to change the rotation angle of the sight in the horizontal direction, the second motor 8 is started, and the output end of the second motor 8 drives the second gear 81 to rotate around its own axis, which can drive the entire turntable 2 to rotate through the meshing gear ring 21, thus driving the entire sight to rotate horizontally, thereby realizing the need for multi-angle processing; after the sight is processed, several fans 41 can be used to dissipate heat from the sight, so that it can be put into use as soon as possible.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
