Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to a clamping and positioning device for hardware parts. Background Technology

[0002] With the rapid development of automated welding technology, higher standards have been set for the accuracy and stability of hardware assembly and positioning. In particular, in the mass production of precision hardware such as automotive parts and pipe connectors, it is necessary to ensure that the assembly position of the pipe and the end cap is accurate and the contact surface is completely matched.

[0003] According to CN221621330U, a welding fixture with a clamping and calibration mechanism is disclosed. This technology discloses a technical solution including a welding table and a clamping assembly. A welding table is fixed above the welding table by bolts, and two sets of calibration positioning rulers are arranged above the welding table. Clamping plates are arranged on both sides of the two sets of calibration positioning rulers, and a moving groove is arranged below the clamping plates. A laser emitter is placed on the left side of the welding table, and the clamping assembly is arranged above the positioning groove. A base is arranged below the welding table. The technical effect is that when welding parts is required, the parts are placed on the welding table above the welding table. The clamping plates are moved by the hydraulic cylinder to squeeze the gap between the parts that need to be welded. At the same time, the clamping assembly clamps the other two sides of the parts. The laser emitter is aligned with the edge of the parts and the calibration positioning rulers to standardize the edge of the parts.

[0004] Traditional clamping devices cannot simultaneously achieve axial positioning of slotted pipe fittings and precise radial pressing of end caps, resulting in incomplete fit between the contact surfaces of the pipe fittings and end caps. Manual operation is not only inefficient, but also makes it difficult to ensure the consistency of assembly positions. Especially in mass production, this inaccurate positioning will directly affect the subsequent welding quality, causing defects such as uneven welds and insufficient connection strength. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping and positioning device for hardware parts. The device uses an automated feeding mechanism to accurately transport the end cap to the clamping station and utilizes an elastic pressure mechanism to achieve a tight fit between the end cap and the pipe, ensuring that the contact surfaces of the two are perfectly aligned. This provides a stable and reliable assembly benchmark for the welding process, significantly improving welding quality and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping and positioning device for hardware parts, comprising a processing table, on which hardware parts are disposed, and a positioning mechanism is provided on the processing table for positioning the hardware parts, the positioning mechanism comprising:

[0007] The slotted tube positioning assembly includes slides fixed on both sides of the top of the processing table, a main positioning seat slidably mounted on the upper end of the slides, a secondary positioning seat fixed on the outer wall of the main positioning seat, a housing fixed on the outer wall of the main positioning seat and located below the secondary positioning seat, a spring slidably mounted on the upper end of the housing and installed between the housing and the housing, and a limit plate fixed at the rear end of the main positioning seat.

[0008] A front positioning assembly is mounted on the machining table and used to fix the hardware from the front end;

[0009] The upper positioning component is set on the processing table and used to fix the hardware parts from the top.

[0010] End cap positioning assembly, set on the processing table and used to fix hardware parts from the side.

A limit plate 216 is fixed at the rear end of the main positioning seat 212.

[0033] The front positioning component 22 is mounted on the processing table 1 and is used to fix the hardware 3 from the front end;

[0034] The upper positioning component 23 is set on the processing table 1 and is used to fix the hardware 3 from the top.

[0035] The end cap positioning assembly 24 is set on the processing table 1 and is used to fix the hardware 3 from the side.

[0036] In this embodiment, the slotted tube body 31 is placed on the main positioning seats 212 on both sides.

[0037] And it is limited by the limiting plate 216; when the end cap body 32 is sent into the space between the support 215 and the auxiliary positioning seat 213 by the end cap positioning assembly 24, the pressure of the spring pushes the support 215 to cooperate with the auxiliary positioning seat 213 to press the end cap body 32, thereby fixing the end cap body 32 to the end of the slotted tube body 31, so that the end cap body 32 and the slotted tube body 31 come into contact, and the contact surfaces of the two are completely fitted, providing a stable process reference for subsequent welding processes.

[0038] Specifically, the end cap positioning assembly 24 includes a fourth cylinder 241 installed on both sides of the top of the processing table 1. The output end of the fourth cylinder 241 is fixed with a fixing head 242, and the lower end of the fixing head 242 is fixed with an outer protrusion 243.

[0039] In this embodiment, the end cap body 32 is placed on the outer protrusion 243 on the fixing head 242, and the bent part at the lower end of the end cap body 32 on the fixing head 242 is driven by the output end of the fourth cylinder 241 to be sent between the support 215 and the secondary positioning seat 213.

[0040] Specifically, the upper positioning component 23 includes upright plates 231 installed on both sides of the top of the processing table 1.

[0041] A connecting rod 232 is pivotally connected to the upper end of the upright plate 231. A bracket 233 is fixed to the lower end of the connecting rod 232. A pressure head 234 is fixed to the upper end of the bracket 233. A third cylinder 235 is installed on the upright plate 231, and the output end of the third cylinder 235 is pivotally connected to the lower end of the bracket 233.

[0042] In this embodiment, the output end of the third cylinder 235 drives the bracket 233 to drive the pressure head 234 to press the slotted tube body 31 from above with the cooperation of the connecting rod 232.

[0043] Specifically, the slotted tube positioning assembly 21 includes a second cylinder 221 installed on both sides of the top of the processing table 1, and a pressure plate 222 is fixed to the output end of the second cylinder 221.

[0044] In this embodiment, the pressure plate 222 is driven by the output end of the second cylinder 221 to press the slotted tube body 31 from the front.

[0045] Specifically, the slotted tube positioning assembly 21 also includes a first cylinder 217 mounted on the upper end of the slide 211 and used to drive the main positioning seat 212 to move.

[0046] In this embodiment, the main positioning seat 212 is finely adjusted by driving the output end of the first cylinder 217 to ensure that the assembly position of the end cap body 32 and the slotted tube body 31 is always in the optimal welding position.

[0047] Specifically, the hardware component 3 includes a slotted tube body 31 placed above the main positioning seats 212 on both sides and an end cap body 32 placed on the outer protrusion seat 243.

[0048] In this embodiment, the device positions the slotted tube body 31 and then positions the end cap body 32 at both ends of the slotted tube body 31 for subsequent welding between the slotted tube body 31 and the end cap body 32.

[0049] The working principle and usage process of this utility model are as follows: First, the slotted tube body 31 is placed on the main positioning seats 212 on both sides and limited by the limiting plate 216; then, the output end of the third cylinder 235 drives the bracket 233 to drive the pressure head 234 to press the slotted tube body 31 from above under the cooperation of the connecting rod 232; at the same time, the output end of the second cylinder 221 drives the pressure plate 222 to press the slotted tube body 31 from the front.

[0050] Then, by placing the end cap body 32 on the outer protrusion 243 on the fixing head 242,

[0051] And through the output end of the fourth cylinder 241, the bent part at the lower end of the end cap body 32 on the fixed head 242 is driven into the space between the support 215 and the auxiliary positioning seat 213.

[0052] Finally, after the end cap body 32 is fed into the space between the support 215 and the secondary positioning seat 213 by the end cap positioning assembly 24, the pressure of the spring pushes the support 215 to cooperate with the secondary positioning seat 213 to press the end cap body 32, thereby fixing the end cap body 32 to the end of the slotted tube body 31, so that the end cap body 32 and the slotted tube body 31 come into contact, and the contact surfaces of the two are completely fitted, providing a stable process reference for subsequent welding processes.
