Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for aluminum parts. Background Technology

[0002] Fixtures are auxiliary tools used to clamp and fix workpieces, ensuring that they are firmly held during processing and preventing them from falling off.

[0003] like Figure 1 As shown, when processing a rectangular aluminum metal part, the middle part of the metal part needs to be processed to form the required through groove a, and a screw hole b and a countersunk groove c for connection and installation are pre-processed on one end sidewall in the length direction of the metal part. During processing, pneumatic clamps are usually used to clamp and limit the metal part in four horizontal circumferential directions.

[0004] Regarding the aforementioned technologies, when pneumatic clamps clamp and limit the metal parts in four horizontal circumferential directions, the end sidewalls of the parts have grooves, which reduces the contact area when the pneumatic clamps contact and press against the sidewalls with grooves, resulting in poor overall clamping stability. Utility Model Content

[0005] In order to ensure that metal parts are firmly clamped during clamping, this application provides an aluminum part tooling fixture.

[0006] The aluminum part tooling fixture provided in this application adopts the following technical solution:

[0007] An aluminum part tooling fixture, comprising:

[0008] The placement platform has at least two limiting side plates on one side surface, and the at least two limiting side plates form a limiting groove. A limiting protrusion is fixedly provided on the surface of the placement platform. When the metal part is placed into the limiting groove, the limiting protrusion abuts against the side surface of the metal part near its end, and the limiting side plate abuts against the other horizontal side wall of the metal part.

[0009] The clamping plate is connected and fixed to the limiting side plate by bolts, and is pressed against the side surface of the metal part away from the placement platform.

[0010] By adopting the above technical solution, under the guidance of the limiting groove, the metal part placed in the limiting groove can be limited in multiple horizontal directions. At the same time, the metal part is pressed by the clamping plate to further improve the clamping firmness of the metal part during the processing.

[0011] Optionally, the placement platform is provided with a clearance groove that penetrates the parallel sidewalls on both sides of the placement platform. The clearance groove is aligned with the through groove of the metal part, and the opening area of ​​the clearance groove is larger than the opening area of ​​the through groove in the horizontal direction.

[0012] By adopting the above technical solution, when the clearance groove and the through groove of the metal part are aligned, the waste generated by the metal part during the processing of the through groove can fall through the clearance groove and is less likely to accumulate, thereby reducing the probability of waste obstructing the processing and making the processing more convenient.

[0013] Optionally, the number of limiting grooves is set to at least two, and adjacent limiting grooves are spaced apart.

[0014] By adopting the above technical solution, at least two limiting grooves, compared to only having a single limiting groove, can increase the number of metal parts that can be processed simultaneously, which helps to improve the processing efficiency of metal parts. At the same time, the spacing between them can make it less likely for them to interfere with each other during processing.

[0015] Optionally, when the clamping plate is fixedly connected to the limiting side plate by bolts, the two ends of the clamping plate respectively press two adjacent metal parts into the limiting groove.

[0016] By adopting the above technical solution, the two ends of the clamping plate clamp the metal parts in the two adjacent limiting grooves respectively, so that the two adjacent metal parts can be clamped at the same time and the fixing efficiency is high.

[0017] Optionally, the clamping plates are provided in at least one set, and each set of clamping plates has two clamping plates, with the two clamping plates in the same set spaced apart.

[0018] By adopting the above technical solution, the two clamping plates in the same group are arranged at intervals so that the two clamping plates can clamp the metal parts separately, and the clamping contact area is increased, which helps to further improve the clamping firmness of the metal parts.

[0019] Optionally, a sliding groove is provided on one side surface of the placement platform. The number of sliding grooves corresponds to the number of limiting side plates. When the limiting side plate is embedded and fixed in the sliding groove, an adjustment gap is formed between the limiting side plate and the metal part.

[0020] By adopting the above technical solution, the sliding groove positions the limiting side plate when it is installed and fixed on the placement platform, so that after the installation of two adjacent limiting side plates, when the metal parts are placed in the limiting groove, a corresponding adjustment gap can be formed, reducing the probability of installation inconvenience caused by slight differences in size of the metal parts during the installation process.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Guided by the limiting groove, the metal part placed in the limiting groove can be limited in multiple horizontal directions. At the same time, the metal part is pressed by the clamping plate to further improve the clamping firmness of the metal part during the processing.

[0023] 2. When the relief groove and the through groove of the metal part are aligned, the waste generated during the machining of the through groove of the metal part can fall through the relief groove and is less likely to accumulate, thereby reducing the probability of waste obstructing the machining process and making the machining process more convenient.

[0024] 3. The sliding groove positions the limiting side plate when it is fixed on the placement platform, so that after the installation of two adjacent limiting side plates, when the metal parts are placed in the limiting groove, the corresponding adjustment gap can be formed, reducing the probability of installation inconvenience caused by slight differences in size of the metal parts during the installation process.

[0030] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0031] This application discloses a tooling fixture for aluminum parts. (Refer to...) Figure 2 and Figure 3The aluminum part tooling fixture includes a placement platform 1 and a clamping plate 2. The surface of the placement platform 1 is provided with a limiting side plate 3 and forms a limiting groove 31. A limiting protrusion 4 is fixedly provided on the surface of the placement platform 1. When the metal part is placed in the limiting groove 31, the limiting side plate 3 and the limiting protrusion 4 respectively limit and abut against the two different horizontal side walls of the metal part. The clamping plate 2 is set on the side wall of the limiting side plate 3 away from the placement platform 1. When the clamping plate 2 is connected and fixed by bolts and the limiting side, it presses the metal part into the limiting groove 31, thereby forming vertical and horizontal limiting on the metal part and improving the installation firmness of the metal part.

[0032] Reference Figure 2 and Figure 3 The limiting side plates 3 are provided in at least two ways. In this embodiment, the number of limiting side plates 3 is described as only three. The three limiting side plates 3 are arranged at intervals along the horizontal direction, so that corresponding limiting grooves 31 are formed between each pair of limiting side plates 3. This allows for the formation of a dual-station limiting groove 31 for two metal parts to be placed and pressed together. Correspondingly, the surface of the placement table 1 is provided with two limiting protrusions 4, which are respectively used to abut one end of the metal parts in the corresponding limiting grooves 31. It should be noted that when the two metal parts are placed in the limiting grooves 31, the adjacent horizontal sidewalls of the two metal parts are tightly attached to the middle limiting side plate 3 to facilitate positioning of the metal parts during subsequent processing.

[0033] Reference Figure 2 The surface of the placement platform 1 near the metal part is provided with a sliding groove 11. The number of sliding grooves 11 corresponds one-to-one with the number of limiting side plates 3. The sliding groove 11 allows the corresponding limiting side plate 3 to be inserted and slid. The corresponding through holes are opened on the placement platform 1 for bolts to pass through and be threadedly connected and fixed to the limiting side plate 3, so that the interval between two adjacent limiting side plates 3 is consistent. When the metal part is placed in the limiting groove 31 and fits against the limiting side plate 3 in the middle, the limiting side plates 3 on both sides can form an adjustment gap 12 with the metal part. Therefore, when metal parts with slight differences in size are placed in the limiting groove 31, it is not easy to cause interference or obstruction, which makes it convenient for the metal parts to be placed or removed.

[0034] Reference Figure 3 and Figure 4 A relief groove 13 is provided on the side surface of the placement table 1 near the metal part. The relief groove 13 penetrates the two parallel surfaces of the placement table 1. The relief groove 13 is aligned with the through groove on the metal part. The opening area of ​​the relief groove 13 in the horizontal direction is larger than the opening area of ​​the through groove, so that the metal waste generated during the processing of the through groove can fall off naturally and will not easily affect the processing due to accumulation.

[0035] Reference Figure 2In order to further increase the firmness of the metal parts within the limiting groove 31, at least one set of pressing plates 2 is provided. In this embodiment, one set is used as an example. There are two pressing plates 2 in one set. The two pressing plates 2 are arranged parallel to each other and spaced apart, so that the two ends of the pressing plates 2 abut against the two metal parts respectively. This increases the pressing area of ​​the metal parts and can press the two metal parts at the same time, making the metal parts less likely to loosen.

[0036] The implementation principle of an aluminum part tooling fixture in this application embodiment is as follows: When installing a metal part, the metal part is placed in the limiting groove 31, so that the two mutually perpendicular side walls of the metal part in the horizontal direction are abutted and limited. Then, the metal part is pressed by the clamping plate 2, so that the metal part is firmly limited in the horizontal and vertical directions and is not easy to come into contact with the sink.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
