Description

Technical Field

[0001] This utility model relates to a metal heat treatment clamping assembly. Background Technology

[0002] Clamping and securing cylindrical and columnar parts is a crucial step in metal heat treatment. Existing heat treatment clamping assemblies have many problems in practical applications and cannot meet the requirements for efficient and precise clamping of parts of different sizes.

[0003] Traditional heat treatment clamping assemblies are typically only suitable for cylindrical or cylindrical parts of specific sizes. When parts vary in size, frequent changes of clamping tools are required, resulting in significant time and labor costs. Existing clamping assemblies cannot be quickly adjusted for cylindrical parts with different inner diameters, leading to low clamping efficiency.

[0004] At the same time, existing clamping components also have insufficient stability when supporting cylindrical parts, which can easily cause parts to shift or tilt during heat treatment, affecting the quality of heat treatment.

[0005] In addition, some clamping components have complex structures, making them inconvenient to operate inside the heat treatment chamber and difficult to quickly clamp and disassemble parts.

[0006] Therefore, a metal heat treatment clamping assembly is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a metal heat treatment clamping assembly to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metal heat treatment clamping assembly, comprising: The heat treatment chamber has an internal support base; The support base and the side wall of the heat treatment box are respectively provided with two sets of support members arranged opposite to each other for clamping cylindrical parts; The lower part of the bearing seat is rotatably connected to the guide seat via an angle fixing bolt; The guide seat moves in a straight line within the heat treatment chamber via a position adjustment assembly, thereby moving the support seat closer to or away from the side wall to clamp the cylindrical part between two sets of support members.

[0009] Preferably, the support member includes a support cylinder, the outer periphery of which is provided with at least two stepped connecting grooves along the axial direction for fitting cylindrical parts with different inner diameters; The middle part of the bearing cylinder is hollow, and an arc-shaped groove is provided at its port to support the end of the cylindrical part.

[0010] Preferably, the lower end of the bearing seat is sleeved on the upper end of the guide seat, and the bearing seat has a radial channel for the angle fixing bolt to pass through; The guide seat has a cylindrical groove and a pentagonal groove on both sides, and the pentagonal groove is coaxial with and connected to the cylindrical groove.

[0011] Preferably, the angle fixing bolt includes a cylindrical plug and a pentagonal bolt rod. A cylindrical plug with a cylindrical insertion portion at its tail end; The pentagonal bolt has a slot that is complementary in shape to the plug part. After the pentagonal bolt is inserted into the pentagonal slot, it prevents the bearing seat from rotating freely relative to the guide seat.

[0012] Preferably, the position adjustment assembly includes a guide rod fixed to the bottom wall of the heat treatment chamber, and guide grooves are provided on both sides of the guide rod along the axial direction; The inner wall of the guide seat is provided with balls that roll in cooperation with the guide groove, so that the guide seat slides linearly along the guide rod.

[0013] Preferably, the guide seat has a connecting plate at its tail end. The connecting plate is connected to one of a plurality of positioning holes distributed axially on the guide rod by a positioning bolt to lock the position of the guide seat.

[0014] Preferably, in the two sets of support members, when the support cylinder located at the lower part of the support seat and the support cylinder located at the lower part of the side wall of the heat treatment box are fixed to a horizontal position by the angle fixing bolt, the lowest point of their arc-shaped grooves are at the same height, so that the cylindrical part is inserted into the middle of the support cylinder at the lower part of the side wall of the heat treatment box and is horizontally supported between the two arc-shaped grooves.

[0015] Preferably, the bottom wall of the heat treatment chamber has a sliding groove for the guide seat to slide at the guide rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The clamping assembly of this invention, through its support component and position adjustment component, can flexibly adapt to cylindrical parts of different sizes. In particular, the design of the stepped connecting groove and the arc-shaped recess allows for the quick clamping of cylindrical parts with different inner diameters, solving the problem that traditional clamping assemblies can only adapt to parts of specific sizes.

[0017] The linear sliding function of the position adjustment component and guide seat allows for rapid adjustment of the carrier position, thus quickly clamping the parts. This avoids the time wasted by frequently changing clamping tools, thereby improving clamping efficiency.

[0018] This component, through the coordinated design of the angle fixing bolt and the carrier seat, along with the arc-shaped groove of the carrier component, can conform to the curve of the part, effectively preventing the part from shifting or tilting during heat treatment, thus improving the quality of heat treatment. It effectively reduces the possibility of part shifting or tilting, improving clamping stability. This is crucial for maintaining the accuracy of the part's position during heat treatment, avoiding problems caused by part movement affecting the quality of heat treatment.

[0019] The use of guide rods, ball bearings, and positioning bolts makes this clamping assembly easy to operate, facilitating the clamping and disassembly of parts, reducing complex operations, and improving work efficiency.

[0020] By engaging the positioning holes on the connecting plate and the guide rod, the guide seat can be precisely locked in position, further improving the accuracy and stability of the entire clamping system.

[0021] Because this component can be quickly adjusted and adapted to parts of different sizes, it avoids the need for frequent tool changes, thus reducing the time and labor costs of manual operation. Attached Figure Description

[0024] To facilitate the resolution of existing problems, this utility model provides a metal heat treatment clamping assembly. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1-7 This utility model provides a metal heat treatment clamping assembly, a heat treatment box 1, which has a bearing seat 2 inside; The support base 2 and the side wall of the heat treatment chamber 1 are respectively provided with two sets of support members 3 arranged opposite to each other for clamping cylindrical parts. Each support member 3 includes a support cylinder 31, which has at least two stepped connecting grooves 311 along its outer periphery for fitting cylindrical parts with different inner diameters. The middle part of the support cylinder 31 is hollow, and an arc-shaped groove 312 for supporting the end of the cylindrical part is provided at its port. In the two sets of support members 3, when the support cylinder 31 located at the lower part of the support base 2 and the support cylinder 31 located at the lower part of the side wall of the heat treatment chamber 1 are fixed to a horizontal position by the angle fixing bolt 4, the lowest point of the arc-shaped groove 312 of the two sets of support members 3 is the same height, so that the cylindrical part is inserted into the middle part of the support cylinder 31 at the lower part of the side wall of the heat treatment chamber 1 and is horizontally supported between the two arc-shaped grooves 312.

[0026] The lower part of the bearing seat 2 is rotatably connected to the guide seat 5 via an angle fixing bolt 4; the angle fixing bolt 4 includes a columnar plug 41 and a pentagonal bolt 42. The columnar plug 41 has a cylindrical insertion part 411 at its tail end; the pentagonal bolt 42 has a slot 421 with a shape complementary to the insertion part 411. After the pentagonal bolt 42 is inserted into the pentagonal slot 52, it prevents the bearing seat 2 from rotating freely relative to the guide seat 5.

[0027] The guide seat 5 moves in a straight line within the heat treatment chamber 1 via the position adjustment component 6, thereby causing the support seat 2 to move closer to or away from the side wall, so as to clamp the cylindrical part between the two sets of support members 3. The guide seat 5 has a cylindrical groove 51 and a pentagonal groove 52 on its two sides, respectively, and the pentagonal groove 52 is coaxial with and connected to the cylindrical groove 51.

[0028] The lower end of the bearing seat 2 is sleeved on the upper end of the guide seat 5, and the bearing seat 2 has a radial channel 21 for the angle fixing bolt 4 to pass through. The position adjustment assembly 6 includes a guide rod 61 fixed to the bottom wall of the heat treatment chamber 1. Guide grooves 611 are provided axially on both sides of the guide rod 61. The inner wall of the guide seat 5 is provided with balls 62 that roll in cooperation with the guide grooves 611, allowing the guide seat 5 to slide linearly along the guide rod 61. A connecting plate 63 is provided at the tail end of the guide seat 5. The connecting plate 63 is selectively connected to one of several axially distributed positioning holes 612 on the guide rod 61 via a positioning bolt 64 to lock the position of the guide seat 5.

[0029] The bottom wall of the heat treatment box 1 is provided with a moving groove 11 for the guide seat 5 to slide at the guide rod.

[0030] The working principle of the metal heat treatment clamping assembly provided by this utility model is as follows: The two ends of the cylindrical part are placed between the two sets of bearing members 3 that are respectively arranged opposite to each other in the bearing cylinder 31 and the heat treatment box 1, so that its inner wall is tightly fitted with the stepped connecting groove 311 to achieve stable support.

[0031] According to the length of the cylindrical part, the position adjustment component 6 is adjusted, and the bearing seat 2 is moved to a suitable position in the heat treatment box 1 through the guide rod 61, ball 62 slide groove and other structures, and the position is locked by the positioning bolt 64 and positioning hole to ensure that the cylindrical part remains stable during the heat treatment process.

[0032] Based on the inner diameter of the cylindrical part, select the corresponding stepped connecting groove 311 on the bearing cylinder 31 for clamping. This allows for quick adaptation of parts with different inner diameters without the need to change tools.

[0033] The bearing seat 2 is adjusted to be horizontal by using the angle fixing bolt 4, so that the lowest point of the bearing cylinder 31 located at the lower part of the bearing seat 2 and the arc-shaped groove 312 of the bearing cylinder 31 located at the lower part of the side wall of the heat treatment box 1 are at the same height, so that the cylindrical part is horizontally supported between the two arc-shaped grooves 312, preventing the bearing seat 2 from shifting due to thermal expansion and other factors during the heat treatment process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
