Description

A planar positioning device for metal fittings Technical Field

[0001] This utility model relates to the field of metal parts processing technology, and in particular to a planar positioning device for metal parts. Background Technology

[0002] Metal fittings refer to fittings made of metal. During the processing of metal fittings, operations such as milling, welding, and drilling are required. At this time, positioning devices are needed to position the metal fittings to facilitate the processing.

[0003] For example, in the prior art, the patent with authorization announcement number CN222308051U discloses a metal parts milling positioning device. This device facilitates the fixing of metal parts by setting positioning and fixing components. By setting pressure sensors, when fixing the metal parts, the pressure sensors sense the pressure and transmit the signal to the controller. The controller controls the extension end of the first electric telescopic rod to stop extending to prevent over-clamping. By setting limit blocks, it is convenient to position the front and rear ends of the two sides of the metal parts. It is suitable for clamping metal parts of various shapes.

[0004] Although this device can be used to clamp and fix different metal parts, it cannot guarantee that the machined surface of the metal part is parallel to the horizontal plane after clamping and fixing the metal part. If the upper surface of the metal part is not horizontal when performing washing and drilling operations, it will affect the processing quality. Therefore, a planar positioning device for metal parts is designed to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a planar positioning device for metal parts.

[0006] The technical problem to be solved by this utility model is to provide a planar positioning device for metal parts, which solves the problem that the existing positioning device for metal parts cannot guarantee the parallelism between the machined surface of the upper surface of the metal part and the horizontal plane when fixing the metal part, thus affecting the processing quality.

[0007] This utility model provides a planar positioning device for metal parts, including a mounting plate, a vertical plate, a hydraulic cylinder, a telescopic rod, a clamping plate, and a planar positioning component. Vertical plates are fixedly installed on both the left and right sides of the upper surface of the mounting plate. A hydraulic cylinder is installed in the center of the outer surface of the vertical plate. A telescopic rod is installed at the output end of the hydraulic cylinder. A clamping plate is detachably installed at the end of the telescopic rod. A planar positioning component is fixedly installed in the center of the inner surface of the mounting plate.

[0008] The planar positioning assembly includes a column, a rotating plate, an electric telescopic rod, and a horizontal plate. The column is fixedly installed in the center of the inner surface of the mounting plate. The top of the column is rotatably mounted on a rotating plate via a bearing. An electric telescopic rod is installed at the outer end of the rotating plate. A horizontal plate is fixedly installed at the output end of the electric telescopic rod.

[0009] Preferably, the clamping plate has a frosted rubber layer on the side surface facing the center of the mounting plate, and a pressure sensor is provided on the side surface facing the center of the mounting plate. A pressure display is embedded in the upper surface of the mounting plate, and the pressure sensor and the pressure display are electrically connected.

[0010] Preferably, when the rotating plate faces one side of the center of the two clamping plates, the horizontal plate is positioned above the center of the mounting plate.

[0011] Preferably, when the electric telescopic rod is extended to its maximum length, the bottom horizontal height of the horizontal plate is equal to the bottom horizontal height of the clamping plate, and when the electric telescopic rod is retracted to its minimum length, the bottom horizontal height of the horizontal plate is higher than the top horizontal height of the vertical plate.

[0012] Preferably, an installation assembly is installed at the connection between the telescopic rod and the clamping plate. The installation assembly includes a positioning post that fixes the top of the telescopic rod and an installation ring that is fixed in the center of the surface of the clamping plate. The installation ring has a through groove on its upper part, a slot is formed on the inner side of the end of the through groove, and an embedding groove is formed on the outer side of the end of the through groove. A spring is fixedly installed in the embedding groove, and a trapezoidal block is fixedly installed at the other end of the spring.

[0013] Preferably, the diameter of the central through hole of the mounting ring is equal to the diameter of the telescopic rod, the width of the through groove is the same as the width of the slot, and the width of both the through groove and the slot is equal to the diameter of the positioning post.

[0014] Preferably, the trapezoidal block is a right-angled trapezoid with a thickness that gradually decreases at the left end.

[0015] Preferably, when the spring is in its naturally extended state, the left end of the trapezoidal block is completely embedded in the embedding groove, and the right side of the trapezoidal block extends out of the embedding groove. When the spring is in its maximum compressed state, the trapezoidal block is completely embedded in the embedding groove.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] 1. This utility model, by setting up a planar positioning component, positions metal parts by first rotating the rotating plate so that the horizontal plate on the rotating plate is between two clamping plates. Then, the workpiece to be clamped is placed between the two clamping plates, and the upper surface of the metal part is pressed tightly against the bottom surface of the horizontal plate, ensuring the horizontal state of the upper processing surface of the metal part. Then, two hydraulic cylinders are activated, and the telescopic rods on the two hydraulic cylinders extend, causing the two clamping plates to move in opposite directions. The two clamping plates cooperate to clamp and fix the metal part, ensuring the quality of the metal part during processing. Moreover, the horizontal plate can be moved up and down by the extension and retraction of the electric telescopic rod, realizing the effect of adjusting the horizontal height of the horizontal plate, which is convenient for planar positioning of metal parts of different sizes. After the metal part is clamped, the horizontal plate is rotated so that the horizontal plate faces away from the mounting plate, so that the planar positioning component will not affect the normal processing of the metal part.

[0018] 2. This utility model, with its installation components, allows for easy replacement of damaged clamping plates or the use of clamping plates of different shapes to hold metal parts of different shapes. By rotating the clamping plate, the rotating plate drives the installation ring to rotate along the telescopic rod. The positioning pin on the telescopic rod disengages from the slot and presses the trapezoidal block, causing the trapezoidal block to fully embed into the embedding groove. At this point, the positioning pin is at the inner end of the through groove. Then, the clamping plate is pulled away from the telescopic rod, and the installation ring disengages from the telescopic rod, achieving the effect of removing the clamping plate from the telescopic rod. The operation is simple and convenient. When a new clamping plate needs to be installed on the telescopic rod, the clamping plate is aligned with the mounting ring of the clamping plate and the positioning pin is aligned with the through groove. The clamping plate is pressed towards one side of the telescopic rod, and the installation ring is fitted onto the telescopic rod. The positioning pin slides along the through groove, pressing the trapezoidal block into the embedding groove. The spring is compressed until the positioning pin is at the innermost end of the through groove. The spring force then pushes the positioning pin into the slot, completing the replacement of the clamping plate. The operation is simple and convenient. Attached Figure Description

[0027] Example:

[0028] As shown in Figures 1-5, an embodiment of this utility model provides a planar positioning device for metal fittings, including a mounting plate 1, a vertical plate 2, a hydraulic cylinder 3, a telescopic rod 301, a clamping plate 4, and a planar positioning assembly. The vertical plates 2 are fixedly installed on both the left and right sides of the upper surface of the mounting plate 1. The hydraulic cylinder 3 is installed in the center of the outer surface of the vertical plate 2. The telescopic rod 301 is installed at the output end of the hydraulic cylinder 3. The clamping plate 4 is detachably installed at the end of the telescopic rod 301. The planar positioning assembly is fixedly installed in the center of the inner surface of the mounting plate 1.

[0029] The planar positioning assembly includes a column 5, a rotating plate 501, an electric telescopic rod 502, and a horizontal plate 503. The column 5 is fixedly installed in the center of the inner surface of the mounting plate 1. The rotating plate 501 is rotatably mounted on the top of the column 5 via a bearing. The electric telescopic rod 502 is installed on the outer end of the rotating plate 501. The horizontal plate 503 is fixedly installed at the output end of the electric telescopic rod 502.

[0030] By incorporating a planar positioning component, the metal parts are positioned by first rotating the rotating plate 501 so that the horizontal plate 503 on the rotating plate 501 is positioned between the two clamping plates 4. Then, the workpiece to be clamped is placed between the two clamping plates, ensuring that the upper surface of the metal part is in close contact with the bottom surface of the horizontal plate 503, thus guaranteeing the horizontal state of the upper processing surface of the metal part. Next, the two hydraulic cylinders 3 are activated, and the telescopic rods 301 on the two hydraulic cylinders 3 extend, causing the two clamping plates 4 to move in opposite directions. The two clamping plates 4 work together to clamp and fix the metal part, ensuring the quality of the metal part during processing. Furthermore, the horizontal plate 503 can be moved up and down by extending and retracting the electric telescopic rod 502, achieving the effect of adjusting the horizontal height of the horizontal plate 503. This facilitates the planar positioning of metal parts of different sizes. After the metal part is clamped, the horizontal plate 503 is rotated so that it faces away from the mounting plate 1, ensuring that the planar positioning component does not affect the normal processing of the metal part.

[0031] In this embodiment, a frosted rubber layer is provided on the side surface of the clamping plate 4 facing the center of the mounting plate 1, and a pressure sensor is provided on the side surface of the clamping plate 4 facing the center of the mounting plate 1. A pressure display is embedded in the upper surface of the mounting plate 1, and the pressure sensor and the pressure display are electrically connected.

[0032] By setting up a pressure sensor and a pressure display, when the clamping plate 4 clamps and fixes the metal parts, the pressure sensor can sense the pressure of the clamping plate 4 clamping the metal parts and display it on the display, so as to prevent the clamping plate 4 from applying too much pressure to the metal parts and prevent the metal parts from deforming.

[0033] In this embodiment, when the rotating plate 501 is facing one side of the center of the two clamping plates 4, the horizontal plate 503 is located above the center of the mounting plate 1.

[0034] In this embodiment, when the electric telescopic rod 502 is extended to its maximum length, the bottom horizontal height of the horizontal plate 503 is equal to the bottom horizontal height of the clamping plate 4. When the electric telescopic rod 502 is retracted to its minimum length, the bottom horizontal height of the horizontal plate 503 is higher than the top horizontal height of the vertical plate 2. When the electric telescopic rod 502 is extended to its minimum length, the vertical plate 2 will not affect the rotation of the rotating plate 501.

[0035] In this embodiment, an installation assembly is installed at the connection between the telescopic rod 301 and the clamping plate 4. The installation assembly includes a positioning post 302 that fixes the top of the telescopic rod 301 and an installation ring 6 that is fixed in the center of the surface of the clamping plate 4. A through groove 601 is opened on the top of the installation ring 6. A slot 602 is opened on the inner side of the end of the through groove 601. An embedding groove is opened on the outer side of the end of the through groove 601. A spring 604 is fixedly installed in the embedding groove. A trapezoidal block 603 is fixedly installed on the other end of the spring 604.

[0036] In this embodiment, the diameter of the central through hole of the mounting ring 6 is equal to the diameter of the telescopic rod 301, the width of the through groove 601 is the same as the width of the slot 602, and the width of both the through groove 601 and the slot 602 is equal to the diameter of the positioning post 302, so that the positioning post 302 can be embedded in the through groove 601 and the slot 602.

[0037] In this embodiment, the trapezoidal block 603 is a right-angled trapezoid with a thickness that gradually decreases at the left end.

[0038] In this embodiment, when the spring 604 is in its naturally extended state, the left end of the trapezoidal block 603 is completely embedded in the embedding groove, and the right side of the trapezoidal block 603 extends out of the embedding groove. When the spring 604 is in its maximum compressed state, the trapezoidal block 603 is completely embedded in the embedding groove, which facilitates the positioning post 302 to press the trapezoidal block 603 into the embedding groove.

[0039] With the installation components, when the clamping plate 4 is damaged and needs to be replaced, or when a different shaped clamping plate 4 is needed to clamp different shaped metal parts, by rotating the clamping plate 4, the clamping plate 4 drives the mounting ring 6 to rotate along the telescopic rod 301. The positioning post 302 on the telescopic rod 301 comes out of the slot 602 and squeezes the trapezoidal block 603, so that the trapezoidal block 603 is completely embedded in the embedding groove. At this time, the positioning post 302 is at the inner end of the through slot 601. Then, the clamping plate 4 is pulled away from the telescopic rod 301, and the mounting ring 6 comes off the telescopic rod 301, thus achieving the effect of removing the clamping plate 4 from the telescopic rod 301. The operation is simple and convenient.

[0040] When a new clamping plate 4 needs to be installed on the telescopic rod 301, align the mounting ring 6 on the clamping plate 4 with the telescopic rod 301, and align the positioning pin 302 with the through groove 601 to press the clamping plate 4 against one side of the telescopic rod 301. The mounting ring 6 is sleeved on the telescopic rod 301, and the positioning pin 302 slides along the through groove 601. The positioning pin 302 presses the trapezoidal block 603 into the embedded groove, and the spring 604 is in a compressed state until the positioning pin 302 is at the innermost end of the through groove 601. The elastic force of the spring 604 will spring the positioning pin 302 into the slot 602, thus completing the replacement of the clamping plate 4. The operation is simple and convenient.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
