Description

Technical Field

[0001] This invention relates to the field of security door processing technology, and in particular to a processing fixture for civil defense security doors. Background Technology

[0002] Security doors are equipped with features that allow them to resist unauthorized opening under certain conditions for a certain period of time, possessing a certain level of security and meeting the corresponding security level. The full name of a security door is "anti-theft security door," which combines anti-theft and security features. Furthermore, the locks used on security doors must be special security door locks with anti-drilling functions that have passed the testing center's inspection. Security doors can be made of different materials, but only doors that meet the standard testing requirements and obtain a production license for security products can be called security doors.

[0003] When processing security doors, it is usually necessary to perform positioning welding or subsequent grinding and polishing on the door panels or connecting parts. Before this, a processing jig is needed to position the workpiece. However, although traditional jigs can adapt to workpieces of different specifications, their positioning methods are limited. They mostly use a combination of a pressure rod and an assembly seat. The pressure rod rotates within the assembly seat, causing the end of the pressure rod to abut against the surface of the workpiece, thereby positioning the workpiece from above.

[0004] However, this structural design cannot further guarantee the stability of the workpiece after it is placed in the fixture. If a large impact force is applied in the lateral direction, it will still cause the workpiece to shift, which will affect subsequent operations. At the same time, the clamping and positioning structure can only play its own role, resulting in the single functionality of the entire fixture. Summary of the Invention

[0005] Technical problems to be solved:

[0006] To address the shortcomings of existing technologies, this invention provides a processing fixture for civil defense and anti-theft doors. By designing multiple freely assembleable clamps, it can achieve positioning and clamping of workpieces in multiple angle directions. The first clamp is also combined with a blowing component, which can remove residues from the workpiece surface during the clamping and positioning process. This demonstrates the flexibility of the overall design and solves the technical problems mentioned in the background art.

[0010] The fixture assembly is detachably mounted on the surface of the machining plate;

[0011] The fixture assembly includes a plurality of first fixtures, second fixtures and third fixtures. The clamping point of the first fixture is located on the upper surface of the workpiece, the clamping point of the second fixture is located on the lower surface of the workpiece, and the third fixture operates synchronously with the second fixture, with the clamping point of the third fixture located on the side of the workpiece. The three types of fixtures work together to position the workpiece.

[0012] In one possible implementation, a bracket is welded to the bottom side of the processing plate, and the surface of the bracket has a threaded groove for screws to be inserted. The screws are used to connect the bracket and the mounting surface, and the bracket is used to support the processing plate.

[0014] The cylinder is mounted on the lower surface of the processing plate, and the free end of the piston rod of the cylinder is movably connected to the pressure arm. The free end of the pressure arm points vertically downward and is configured as a pressure head. The surface of the processing plate is provided with a pressure head located directly below the pressure head.

[0015] Support components, which can be assembled as needed, serve to support the workpiece;

[0016] The mounting base is mounted on the upper surface of the processing plate, and the mounting base is connected to the middle of the pressure arm by a connecting piece. The connecting piece can also be deflected to ensure that the entire first fixture can be clamped.

A hollow strip is provided above the fixing ring, and the fixing ring and the hollow strip are connected by a bent rod. A hollow flexible tube is provided inside the bent rod, and the pressure bladder is connected to the hollow strip through the hollow flexible tube. Several air holes are opened on the surface of the hollow strip, and the airflow discharged from the air holes can complete the purging treatment of the workpiece surface.

[0019] In one possible implementation, the second clamp includes a motor, a connecting seat, and a pull rod;

[0020] The motor is mounted on the upper surface of the processing plate, and the output end of the motor is connected to the pull rod through a transmission component. The transmission component includes a drive rod and a transmission rod connected by a rotating shaft.

[0034] This application provides a processing fixture for civil defense and anti-theft doors. By designing multiple freely assembleable clamps, it can achieve positioning and clamping of workpieces in multiple angle directions. The first clamp is also combined with a blowing component, which can remove residues on the workpiece surface during the clamping and positioning process. This reflects the flexibility of the overall design and solves the technical problems mentioned in the background art.

[0035] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0036] Example 1:

[0037] This embodiment describes the specific structure of a processing fixture for civil defense and anti-theft doors, such as... Figures 1-6 As shown, the assembly includes a processing plate 1 and a fixture assembly. Each fixture in the fixture assembly is position-adjustable and can be configured as follows: Figure 1 As shown, the positioning process for the two workpieces 5 is completed simultaneously.

[0038] The fixture assembly is detachably mounted on the surface of the machining plate 1;

[0039] The fixture assembly includes several first fixtures 3, second fixtures 4 and third fixtures. The clamping point of the first fixture 3 is located on the upper surface of the workpiece 5, the clamping point of the second fixture 4 is located on the lower surface of the workpiece 5, the third fixture operates synchronously with the second fixture 4, and the clamping point of the third fixture is located on the side of the workpiece 5, where the third fixture and the second fixture 4 are in a state of synchronous movement.

[0040] In some examples, a bracket 2 is welded to the bottom side of the processing plate 1. The surface of the bracket 2 has a threaded groove for screws to be inserted, and the screws are used to connect the bracket 2 and the mounting surface. The bracket 2 at this location is used to support the entire processing plate 1.

[0041] In some examples, the first fixture 3 includes a cylinder 301, a mounting base 302, and a pressure arm 303; the cylinder 301 is mounted on the lower surface of the processing plate 1, and the free end of the piston rod of the cylinder 301 is movably connected to the pressure arm 303; the mounting base 302 is mounted on the upper surface of the processing plate 1, and the mounting base 302 is connected to the middle of the pressure arm 303 by a connecting piece 7; the free end of the pressure arm 303 is vertically downward and is set as a pressure head 6, which may be made of rubber. A support member 8 is provided on the surface of the processing plate 1 at a position directly below the pressure head 6, and the support member 8 at this position can support the workpiece 5 from below.

[0042] In some examples, a purge assembly is also mounted above cylinder 301;

[0043] The purging assembly includes a pressure bladder 9 fitted onto the outer surface of the piston rod, and a fixing ring 10 welded to the mounting base 302 is provided at the upper end of the pressure bladder 9. A hollow strip 12 is provided above the fixing ring 10, and the fixing ring 10 and the hollow strip 12 are connected by a bending rod 11. A hollow hose is provided inside the bending rod 11, and the pressure bladder 9 is connected to the hollow strip 12 through the hollow hose. Several air holes 13 are opened on the surface of the hollow strip 12.

[0044] During the specific operation, the cylinder 301 in the first clamp 3 drives the pressure arm 303 to deflect. At this time, the pressure head 6 moves down to clamp the upper surface of the workpiece 5. At the same time, the entire pressure bladder 9 also retracts upward. Since the position of the fixing ring 10 is fixed, when the airflow generated by the pressure bladder 9 is ejected from each air hole 13 through the hollow hose, the state of the bending rod 11 will not be affected. The user can manually adjust the bending rod 11 so that the hollow strip 12 moves to the closed position and remains stable. The generated airflow can remove the adhering substances on the surface of the workpiece 5, achieving the cleaning effect.

[0045] By adopting the above technical solution:

[0046] The above design incorporates multiple freely assembleable fixtures, enabling the positioning and clamping of workpiece 5 from multiple angles. The first fixture 3 is also integrated with a purging assembly, which removes residues from the surface of workpiece 5 during the clamping and positioning process. This demonstrates the flexibility of the overall design, allowing the fixtures to be configured according to the specifications of workpiece 5, ensuring that workpiece 5 remains stable during processing and facilitating subsequent operations.

[0047] Example 2:

[0048] Based on Example 1, this example describes the specific structure of the second and third clamps in a jig for processing civil defense and anti-theft doors, such as... Figures 4-6 As shown, the second clamp 4 includes a motor 401, a connecting seat 402 and a pull rod 403. The pull rod 403 can be translated within the connecting seat 402. After the pull rod 403 aligns with the slot on the lower surface of the workpiece 5, the pull rod 403 can move to hold and position the workpiece 5.

[0049] Motor 401 is mounted on the upper surface of processing plate 1, and the output end of motor 401 is connected to pull rod 403 via a transmission component.

[0050] The connection and transmission component includes a drive rod 15 and a transmission rod 14 connected by a rotating shaft, where the drive rod 15 can deflect to a certain extent.

[0051] The angle is small, but the transmission rod 14 always maintains linear movement under the limiting action of the connecting seat 402;

[0052] The connecting seat 402 is mounted on the surface of the processing plate 1, and the pull rod 403 is movably inserted into the connecting seat 402, as detailed in the following reference. Figure 4 and Figure 5 This is immediately apparent.

[0053] In some examples, the third fixture includes a base 18 mounted on the surface of the processing plate 1 and a side abutment 19 deflectedly mounted in the base 18. A gear 17 is provided at the end of the shaft connecting the side abutment 19 and the base 18. A strip groove 16 is provided on the side of the transmission rod 14 facing the third fixture, and a rack 20 that meshes with the gear 17 is welded in the strip groove 16.

[0054] During the specific operation, the motor 401 in the second fixture 4 drives the drive rod 15 to deflect, and then the transmission rod 14 drives the pull rod 403 to move. At the same time, the rack 20 on the transmission rod 14 also drives the gear 17 to deflect, so that the side abutment rod 19 in the third fixture deflects in the base 18, completing the abutment-type fixation of the side of the workpiece 5.

[0055] By adopting the above technical solution:

[0056] The second clamp 4 and the third clamp designed above are used in conjunction with the first clamp 3 in Embodiment 1. The third clamp is combined with the second clamp 4. When the second clamp 4 completes the pulling and positioning of the bottom of the workpiece 5, the transmission of power by the gear 17 and the rack 20 can enable the side abutment rod 19 in the third clamp to also complete the synchronous positioning operation, avoiding the need for other drive structures.

[0057] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
