Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinet processing, in particular to a positioning fixture for processing electrical cabinet fastening parts. Background Art

[0002] Electrical cabinets are generally made of steel plates and are used to store and protect electrical components. During the processing of electrical cabinets, steel plates are often assembled together by bolts, metal connectors, etc., and holes are opened in the steel plates and metal connectors to facilitate wiring when components are subsequently assembled.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 A positioning fixture for processing a fastening part of an electrical cabinet comprises a base 1, a boss 2 is fixedly mounted on the top of the base 1, a material drop groove 3 is provided on the top of the boss 2 and runs through the bottom of the base 1, and the material drop groove 3 is provided to facilitate the falling of debris generated in drilling. A receiving groove 4 is provided on the top of the boss 2, a clamping assembly 5 is provided on both the left and right sides of the boss 2, and an adjustment assembly 6 is movably connected to the front and rear sides of the clamping assembly 5, and a limit assembly 7 is movably connected to the front and rear sides of the boss 2, and the limit assembly 7 abuts against the surface of the adjustment assembly 6.

[0024] See also Figure 2-3The clamping assembly 5 includes two groups of supports 51 fixedly installed on the left and right sides of the boss 2, and a slide column 52 is fixedly installed between each group of supports 51. A slider 53 is slidably connected to the surface of the slide column 52. A guide groove 54 is formed on the surface of the slider 53. The slide column 52 is inserted into the slider 53 through the guide groove 54. The upper half of the guide groove 54 is vertical, and the lower half of the guide groove 54 is inclined toward the side close to the boss 2. The width of the guide groove 54 is equal to the diameter of the slide column 52. Therefore, when the slider 53 moves from top to bottom, the slider 53 will first approach the boss 2 and then move vertically downward. An L-shaped plate 55 is fixedly installed on the top of the slider 53, and a guide rod 56 is provided through the top of the L-shaped plate 55. The guide rod 56 is slidably connected to the L-shaped plate 55. A pressure plate 57 is fixedly installed on the bottom of the guide rod 56. A spring 58 is fixedly installed between the pressure plate 57 and the L-shaped plate 55. The pressure plate 57 is located directly above the accommodating groove 4. The guide rod 56 and the spring 58 are arranged in an array between the pressure plate 57 and the L-shaped plate 55. A baffle is provided on the top of the guide rod 56, and the baffle abuts against the top of the L-shaped plate 55. The elasticity of the spring 58 allows the pressure plate 57 to be flexibly pressed on the top of the fixed part to prevent excessive pressure from squeezing and deforming the fixed part. Connecting plates 59 are fixedly installed on the front and rear sides of the slider 53.

[0025] See also Figure 4 The adjustment assembly 6 includes a horizontal plate 61 arranged on the front and rear sides of the boss 2, and a handle 62 is fixedly installed on the top of the horizontal plate 61. The handle 62 is arranged to facilitate holding and synchronously push the horizontal plate 61 up and down to move. Avoidance grooves 63 are provided at both ends of the horizontal plate 61, and the connecting plate 59 is inserted in the avoidance grooves 63 and slides. Two spacers are fixedly installed at the end of the connecting plate 59, and the spacers are clamped on the front and rear sides of the horizontal plate 61. Through the setting of the spacers, the connecting plate 59 is stably slidably connected in the avoidance groove 63. Through the setting of the avoidance groove 63, when the sliding column 52 slides in the lower half of the guide groove 54, the offset of the slider 53 and the connecting plate 59 in the left and right directions is avoided.

[0026] See also Figure 1-2 The limit assembly 7 includes two blocks 71 inserted at the front and rear sides of the boss 2. The front and rear sides of the boss 2 are provided with mounting grooves 72 corresponding to the blocks 71. A second spring 73 is fixedly installed between the blocks 71 and the inner wall of the mounting groove 72. The upper and lower sides of the free end of the blocks 71 are both inclined surfaces. When the cross plate 61 abuts against the bottom of the blocks 71, the slide post 52 abuts against the top wall of the guide groove 54. When the cross plate 61 abuts against the top of the blocks 71, the slide post 52 abuts against the bottom wall of the guide groove 54.

[0027] Working principle: By holding the handle 62 and pulling the horizontal plate 61 upward, the connecting plate 59 is driven to move upward, and the sliding column 52 moves downward along the guide groove 54 relative to the slider 53, so that the slider 53 moves upward and away from the boss 2, so that the pressure plate 57 moves to the upper side of the receiving groove 4 and moves sideways to expose the receiving groove 4, making it convenient to place the fastener in the receiving groove 4.

[0028] Afterwards, the handle 62 is held and pushed downward, so that the cross plate 61 squeezes the end of the block 71, and the block 71 is retracted into the interior of the installation groove 72. The spring 2 73 is squeezed and contracted. When the cross plate 61 passes over the block 71, the block 71 pops out and is blocked at the top of the cross plate 61 under the elastic action of the spring 2 73.

[0029] By moving the horizontal plate 61 downward, the slider 53 and the connecting plate 59 are pushed downward, and the sliding column 52 slides in the guide groove 54, so that the slider 53 first approaches the boss 2 and then moves vertically downward, so that the pressure plate 57 is squeezed on the top of the fastener, and cooperates with the bottom wall of the accommodating groove 4 to clamp the fastener from the edge. The setting of the spring 58 prevents the fastener from being deformed by excessive pressure.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
