TECHNICAL FIELD

[0001] The utility model relates to electrical cabinet fixed connection piece processing technical field more specifically, it relates to a kind of positioning fixture for electrical cabinet fixed connection piece processing. BACKGROUND

[0002] Electrical cabinet is a kind of cabinet body for concentrating installation and protection electrical equipment, component and wiring system, electrical cabinet is placed in a plurality of electrical equipment, it is convenient to carry out unified monitoring, maintenance and management to electrical system, in addition, electrical cabinet can prevent dust, humidity, corrosive gas and other external factors damage to internal electrical equipment.

[0003] At present, electrical cabinet fixed connection piece is used to connect electrical cabinet and other equipment, structure or electrical cabinet internal component, its main role is to ensure that electrical cabinet remains stable in various working environments, and guarantee the connection between electrical cabinet internal components reliable, so as to guarantee the normal operation of electrical system.

[0004] However, electrical cabinet and electrical cabinet internal component connection structure is complex, and the shape of required fixed connection piece is also relatively special, so fixed connection piece needs to be processed correspondingly, so that the fixed connection piece after processing is adapted to electrical cabinet, but the existing ordinary fixture cannot meet the processing needs of fixed connection piece, and the positioning fixture for electrical cabinet fixed connection piece processing is proposed to improve the existing problems. UTILITY MODEL CONTENT

[0005] In view of the deficiencies in the prior art, the utility model aims at providing a positioning fixture for electrical cabinet fixed connection piece processing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A positioning fixture for electrical cabinet fixed connection piece processing, comprising a support assembly, one side of the support assembly is provided with a clamping assembly, and a fixed connection piece is arranged at the middle position of the clamping assembly.

[0008] The support assembly comprises a first support frame, one side of the first support frame is provided with a second support frame, an installation frame is arranged above the second support frame, and an installation plate is arranged at the top of the installation frame.

[0009] The fixed connection piece comprises a first workpiece, one side of the first workpiece is provided with a second workpiece, and the second workpiece and the first workpiece are placed on the top of the installation plate.

[0010] The clamping assembly includes a fixed frame, which is I-shaped. A cylinder is located in the middle of the fixed frame, and an output shaft is connected to the output end of the cylinder. A set of lead screws is provided on both sides of the output shaft. The two sets of lead screws pass through the fixed frame and are slidably connected to the fixed frame.

[0011] By adopting the above technical solution, the first workpiece and the second workpiece are two separate parts before processing. The first workpiece and the second workpiece are both trapezoidal in shape. After processing, the first workpiece and the second workpiece form an L-shaped fixed connection. However, during the processing, the first workpiece and the second workpiece are processed in close contact. During this process, the first workpiece and the second workpiece are prone to displacement. Therefore, a clamping assembly is set to clamp the first workpiece and the second workpiece to assist in completing the processing work. By setting an I-shaped fixing frame, the movement requirements of the two sets of lead screws and output shafts can be met. The crossbar in the middle of the I-shaped fixing frame and the upper and lower cross plates form a stable structure. When subjected to tensile force, the upper and lower cross plates can distribute the force to a larger area, while the middle crossbar can enhance the bending resistance of the entire structure.

[0012] The present invention is further configured such that: a fixing plate is provided at the end of the output shaft away from the cylinder, the fixing plate is fixedly connected to the output shaft, and the two sets of lead screws are respectively fixedly connected to the fixing plate.

[0013] The present invention is further configured such that: a first clamping plate is provided on the side of the fixing plate away from the output shaft, and the first clamping plate is fixedly connected to the fixing plate.

[0014] The present invention is further configured such that: a second clamping plate is provided on the same side of the first clamping plate and the fixing plate, the second clamping plate is fixedly connected to the first clamping plate, and the second clamping plate and the first clamping plate are perpendicular to each other.

[0015] The present invention is further configured such that: a third clamping plate is provided on the outer side of the first workpiece, the third clamping plate is Z-shaped, and the third clamping plate is installed on the top of the mounting plate.

[0016] The present invention is further configured such that: a fourth clamping plate is provided on the side of the second workpiece away from the first workpiece, the fourth clamping plate is fixedly connected to the third clamping plate, and the fourth clamping plate and the third clamping plate are perpendicular to each other, and the fourth clamping plate is installed on the top of the mounting plate.

[0017] By adopting the above technical solution, and by setting the third clamping plate to a Z-shaped structure, the third clamping plate provides multiple support points and contact areas for the first and second workpieces through its tortuous shape. These support points and contact areas are distributed in different directions, so that the objects can be supported and constrained from multiple directions when subjected to external interference forces. During the clamping process, the first and second clamping plates gradually move, and at this time, the third clamping plate can limit the first and second workpieces, ensuring that the first and second workpieces are inside the third clamping plate during the movement of the first and second clamping plates. In addition, the third clamping plate can provide multiple positioning points and positioning directions. When the first and second workpieces are placed along the third clamping plate, precise positional constraints can be formed at each bend and straight section.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By setting up a first clamping plate, a second clamping plate, a third clamping plate, and a fourth clamping plate to form a clamping mechanism that is compatible with the first workpiece and the second workpiece, the clamping mechanism surrounds the first workpiece and the second workpiece during the processing, providing multiple support points and contact areas for the first workpiece and the second workpiece, so that the first workpiece and the second workpiece remain stable during the processing and ensure the normal progress of subsequent processing.

[0020] 2. By setting up an I-shaped fixing frame, the crossbar in the middle and the upper and lower cross plates of the I-shaped fixing frame form a stable structure. When subjected to tensile force, the upper and lower cross plates can distribute the force to a larger area, while the middle crossbar can enhance the bending resistance of the entire structure and meet the movement requirements of the two sets of lead screws and output shafts.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Example 1, please refer to Figures 1-4 The present invention provides the following technical solution:

[0031] See Figure 1 A positioning fixture for processing electrical cabinet fasteners includes a support assembly 1, a clamping assembly 3 on one side of the support assembly 1, and a fastener 2 in the middle of the clamping assembly 3.

[0032] See Figure 2 The support assembly 1 includes a first support frame 11, a second support frame 12 is provided on one side of the first support frame 11, a mounting frame 13 is provided above the second support frame 12, and a mounting plate 14 is provided on the top of the mounting frame 13.

[0033] See Figures 2-4 The fastener 2 includes a first workpiece 21, and a second workpiece 22 is provided on one side of the first workpiece 21. The second workpiece 22 and the first workpiece 21 are placed on the top of the mounting plate 14. Before processing, the first workpiece 21 and the second workpiece 22 are two separate parts. The first workpiece 21 and the second workpiece 22 are both trapezoidal in shape. After processing, the first workpiece 21 and the second workpiece 22 form an L-shaped fastener 2. However, during the processing, the first workpiece 21 and the second workpiece 22 are processed in close contact. During this process, the first workpiece 21 and the second workpiece 22 are prone to displacement. Therefore, a clamping assembly 3 is provided to clamp the first workpiece 21 and the second workpiece 22 to assist in completing the processing work.

[0034] See Figures 2-4The clamping assembly 3 includes a fixing frame 32, which is I-shaped and fixedly installed on the top of the mounting frame 13. A cylinder 31 is located in the middle of the fixing frame 32, and an output shaft 34 is connected to the output end of the cylinder 31. A set of lead screws 33 is provided on both sides of the output shaft 34. The two sets of lead screws 33 pass through the fixing frame 32 and are slidably connected to the fixing frame 32. The crossbar in the middle of the I-shaped fixing frame 32 and the upper and lower cross plates form a stable structure. When subjected to tension, the upper and lower cross plates can distribute the force to a larger area, while the middle crossbar can enhance the bending resistance of the entire structure. By setting the I-shaped fixing frame 32, the movement requirements of the two sets of lead screws 33 and the output shaft 34 can be met.

[0035] See Figures 2-4 A fixed plate 35 is provided at the end of the output shaft 34 away from the cylinder 31. The fixed plate 35 is fixedly connected to the output shaft 34. Two sets of lead screws 33 are fixedly connected to the fixed plate 35 respectively. When the cylinder 31 is started, the cylinder 31 drives the output shaft 34 to move linearly. Since the fixed plate 35 is fixedly connected to the output shaft 34, the fixed plate 35 moves linearly with the output shaft 34. Since the lead screw 33 is fixedly connected to the fixed plate 35 and the lead screw 33 is slidably connected to the fixed frame 32, the lead screw 33 can move linearly along the fixed frame 32 with the output shaft 34.

[0036] See Figures 2-4 A first clamping plate 36 is provided on the side of the fixed plate 35 away from the output shaft 34. The first clamping plate 36 is fixedly connected to the fixed plate 35. Under the drive of the cylinder 31, the fixed plate 35 can drive the first clamping plate 36 to move linearly.

[0037] See Figures 2-4 A second clamping plate 37 is provided on the same side of the first clamping plate 36 and the fixing plate 35. The second clamping plate 37 is fixedly connected to the first clamping plate 36 and is perpendicular to the first clamping plate 36. The perpendicular angle between the second clamping plate 37 and the first clamping plate 36 is adapted to the outer angle of the first workpiece 21 and the second workpiece 22, so as to stably clamp the first workpiece 21 and the second workpiece 22.

[0038] See Figures 2-4 A third clamping plate 38 is provided on the outer side of the first workpiece 21. The third clamping plate 38 is Z-shaped and is installed on the top of the mounting plate 14. The third clamping plate 38 is located on the outer side of the first workpiece 21 and the second workpiece 22 and fits against the outer side of the first workpiece 21 and the second workpiece 22. When the first workpiece 21 and the second workpiece 22 are placed on the top of the mounting plate 14, the third clamping plate 38 can provide multiple positioning points and positioning directions. When the first workpiece 21 and the second workpiece 22 are placed along the third clamping plate 38, precise positional constraints can be formed at each bend and straight section.

[0039] By setting the third clamping plate 38 into a Z-shaped structure, the third clamping plate 38 provides multiple support points and contact areas for the first workpiece 21 and the second workpiece 22 through its tortuous shape. These support points and contact areas are distributed in different directions, so that the objects can be supported and constrained from multiple directions when subjected to external disturbance forces. During the clamping process, the first clamping plate 36 and the second clamping plate 37 gradually move. At this time, the third clamping plate 38 can limit the first workpiece 21 and the second workpiece 22, ensuring that the first workpiece 21 and the second workpiece 22 are inside the third clamping plate 38 during the movement of the first clamping plate 36 and the second clamping plate 37.

[0040] See Figures 2-4 A fourth clamping plate 39 is provided on the side of the second workpiece 22 away from the first workpiece 21. The fourth clamping plate 39 is fixedly connected to the third clamping plate 38 and is perpendicular to the third clamping plate 38. The fourth clamping plate 39 is installed on the top of the mounting plate 14 and fits against the second workpiece 22. In addition to the positioning of the third clamping plate 38, the fourth clamping plate 39 also limits the first workpiece 21 and the second workpiece 22. By setting the first clamping plate 36, the second clamping plate 37, the third clamping plate 38, and the fourth clamping plate 39, a clamping mechanism adapted to the first workpiece 21 and the second workpiece 22 is formed. During the processing, the clamping mechanism surrounds the first workpiece 21 and the second workpiece 22, providing multiple support points and contact areas for the first workpiece 21 and the second workpiece 22, so that the first workpiece 21 and the second workpiece 22 remain stable during the processing and ensure the normal progress of subsequent processing.

[0041] Specifically, before processing the first workpiece 21 and the second workpiece 22, the first workpiece 21 and the second workpiece 22 are first placed on the top of the mounting plate 14. The third clamping plate 38 and the fourth clamping plate 39 position one side of the first workpiece 21 and the second workpiece 22. Then, the cylinder 31 is started, and the cylinder 31 drives the output shaft 34 to move linearly. The fixed plate 35 moves with the output shaft 34. Under the drive of the fixed plate 35, the first clamping plate 36 and the second clamping plate 37 move together. During the gradual movement, the first clamping plate 36 and the second clamping plate 37 come into contact with the other side of the first workpiece 21 and the second workpiece 22, so as to achieve stable clamping of the first workpiece 21 and the second workpiece 22.

[0042] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
