Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, and in particular to an adjustable heat treatment furnace feeding and positioning fixture. Background Technology

[0002] Existing heat treatment furnace loading and positioning fixtures are mostly fixed structures, and the size and position of their positioning components are usually not adjustable. For example, when processing workpieces of different sizes, operators need to change to suitable positioning fixtures or manually adjust the workpiece position. This not only increases operational complexity but also easily leads to decreased loading stability due to inaccurate positioning. In addition, traditional fixtures often struggle to quickly adapt to the positioning requirements of different workpiece specifications when facing diverse production needs, thus affecting overall production efficiency.

[0003] To address the aforementioned issues, some designs have introduced simple adjustable positioning mechanisms, but these technologies still have certain limitations. First, the adjustment range is limited, only suitable for workpieces within a specific size range, and cannot achieve flexible adjustment across the entire range. Second, during adjustment, positioning accuracy is easily affected by human operation, leading to workpiece position deviations. Finally, existing adjustable mechanisms are typically complex in design, with cumbersome adjustment steps, further reducing production efficiency. Therefore, there is an urgent need for a heat treatment furnace loading and positioning fixture that can balance flexibility, accuracy, and stability. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable heat treatment furnace feeding and positioning fixture to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

One end of the adjusting rod is fixedly connected to the positioning plate, and the other end passes through the base and is threadedly connected to the base to control the movement of the positioning plate along the guide member.

[0007] To further elaborate, the driving component in the adjustment assembly is a stepper motor, and the transmission mechanism includes a driving gear, a driven gear, and a transmission shaft. The driving gear is interference-fitted with the output shaft of the stepper motor, and the driven gear is sleeved on the transmission shaft and meshes with the driving gear. Both ends of the transmission shaft are rotatably connected to the base via first rolling bearings.

A second rolling bearing is sleeved on the outer side of the adjustment rod. The inner ring of the second rolling bearing is tightly fitted with the adjustment rod, and the outer ring of the second rolling bearing is fixedly connected to the base to ensure axial stability of the adjustment rod during rotation.

[0008] The base has a rectangular guide groove at its top. The guide includes two parallel slide rails, the bottom of which are fixedly connected to the base with bolts. The top of the slide rails has a T-shaped guide groove, and the bottom of the positioning plate has a T-shaped slider that matches the T-shaped guide groove. The T-shaped slider is embedded in the T-shaped guide groove and slidably connected to the slide rail. Limiting protrusions are provided on both sides of the positioning plate.

One end of the limiting rod is fixedly connected to the adjustment rod, and the other end passes through the base and is slidably connected to the base. The limiting block is sleeved on the limiting rod and fixedly connected to the base by screws. The inner sidewall of the limiting block is provided with an arc-shaped groove, which fits against the outer sidewall of the limiting rod to limit the axial movement range of the adjustment rod.

[0011] The base has a mounting bracket at its bottom, which includes a support plate and reinforcing ribs.

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

[0015] By incorporating adjustment and positioning components, the positioning plate can move precisely along the guide to accommodate workpieces of different sizes. The threaded connection between the adjusting rod and the base ensures a smoother adjustment process, avoiding errors caused by traditional manual adjustments.

The inner wall of the metal bushing 13 is provided with internal threads for connection with the mounting bolts of the heat treatment furnace, thereby fixing the tooling on the heat treatment furnace.

[0027] The adjustment assembly 2 includes a drive component 4, a transmission mechanism 5, an adjustment rod 6, and a limiting mechanism 9. The drive component 4 is a stepper motor, and its output shaft is connected to the driving gear in the transmission mechanism 5 via an interference fit. The driving gear meshes with the driven gear, which is sleeved on the transmission shaft. Both ends of the transmission shaft are rotatably connected to the base 1 via first rolling bearings. An external thread section is provided in the middle of the transmission shaft, and the external thread section is threadedly connected to the adjustment rod 6. One end of the adjustment rod 6 passes through the base 1 and is threadedly connected to the base 1, while the other end is fixedly connected to the positioning plate 7. A second rolling bearing is sleeved on the outer side of the adjustment rod 6. The inner ring of the second rolling bearing is tightly fitted with the adjustment rod 6, and the outer ring is fixedly connected to the base 1 to keep the adjustment rod 6 axially stable during rotation. The limiting mechanism 9 includes a limiting rod and a limiting block. One end of the limiting rod is fixedly connected to the adjusting rod 6, and the other end passes through the base 1 and is slidably connected to the base 1. The limiting block is sleeved on the limiting rod and fixedly connected to the base 1 by screws. The inner side wall of the limiting block is provided with an arc-shaped groove, which fits against the outer side wall of the limiting rod to limit the axial movement range of the adjusting rod 6.

[0028] The positioning assembly 3 includes a positioning plate 7, a guide member 8, and an auxiliary positioning member 12. The positioning plate 7 is slidably connected to the base 1 via the guide member 8. The guide member 8 includes two parallel slide rails, the bottom of which is fixedly connected to the base 1 by bolts. The top of the slide rails is provided with a T-shaped guide groove. The bottom of the positioning plate 7 is provided with a T-shaped slider that matches the T-shaped guide groove. The T-shaped slider is embedded in the T-shaped guide groove and slidably connected to the slide rail. Limiting protrusions are provided on both sides of the positioning plate 7. The outer side of the limiting protrusions fits against the inner side of the base 1 to prevent the positioning plate 7 from shifting during movement. A positioning hole is provided at the center of the positioning plate 7. A positioning sleeve 11 is embedded in the positioning hole. The inner wall of the positioning sleeve 11 is provided with multiple sets of elastic clips. The inner side of the elastic clips is provided with anti-slip texture. A locking nut is provided on the outer side of the positioning sleeve 11. The locking nut is connected to the positioning hole by threads to fix the position of the positioning sleeve 11. The auxiliary positioning component 12 includes a support column and a positioning pin. The support column is connected to the positioning plate 7 by threads. The bottom of the positioning pin is provided with a spherical head, which is embedded in the top of the support column and connected to the support column by a spring.

[0029] The drive unit 4 is connected to an external power supply via a control circuit. The control circuit includes a signal receiving module, a signal processing module, and a drive module. The signal receiving module receives external input signals, the signal processing module converts the input signals into control signals, and the drive module drives the stepper motor to operate according to the control signals. The control circuit also includes a feedback module, which includes a photoelectric encoder. The photoelectric encoder is coaxially connected to the drive shaft and is used to monitor the rotation angle of the drive shaft in real time and feed the data back to the signal processing module.

[0030] In actual operation, when the position of the positioning plate 7 needs to be adjusted, the external control signal is transmitted to the signal processing module through the signal receiving module. The signal processing module converts the signal into a control signal and sends it to the drive module. The drive module drives the stepper motor to run, and the output shaft of the stepper motor drives the drive gear to rotate. The drive gear drives the driven gear to rotate through meshing transmission. The rotation of the driven gear further drives the transmission shaft to rotate. The external thread section of the transmission shaft is threadedly connected to the adjusting rod 6, causing the adjusting rod 6 to move axially. The movement of the adjusting rod 6 pushes the positioning plate 7 to slide along the guide member 8, thereby realizing the position adjustment of the positioning plate 7. The cooperation between the limiting block and the limiting rod in the limiting mechanism 9 limits the axial movement range of the adjusting rod 6, avoiding structural damage caused by excessive movement. After the positioning plate 7 moves into place, the elastic clamp and anti-slip texture in the positioning sleeve 11 clamp the workpiece, and the locking nut ensures that the position of the positioning sleeve 11 is fixed. The spherical head design of the auxiliary positioning member 12 can adapt to the irregular shape of the workpiece surface, further improving the positioning accuracy.

[0031] As can be seen from the above specific embodiments, the tooling of this utility model achieves flexible, accurate and stable workpiece positioning function through the reasonable connection and cooperation between the various components, which significantly improves the working efficiency and reliability of the heat treatment furnace feeding.

[0032] In summary, this invention significantly improves the efficiency and reliability of heat treatment furnace loading through the rational connection and coordinated operation of its various components. Specifically, the design of the adjusting component 2 enables precise movement of the positioning plate 7, the elastic clamps and anti-slip texture of the positioning component 3 enhance the workpiece clamping stability, while the limiting mechanism 9 and the auxiliary positioning component 12 respectively improve operational safety and positioning accuracy. These technical features work together to enable this invention to meet diverse production needs and overcome the shortcomings of existing technologies.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
