Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a positioning device for processing a stainless steel shell. Background Art

[0002] Stainless steel is steel that is not easy to rust. In fact, some stainless steel is both rust-proof and acid-resistant (corrosion-resistant). The rust-proof and corrosion-resistant properties of stainless steel are due to the formation of a chromium-rich oxide film (passivation film) on its surface. When processing formed stainless steel, the factory needs to fix the stainless steel first, then polish the surface and the inside. During the processing of the stainless steel shell, a positioning device is needed to prevent the workpiece from shifting.

[0003] However, in some existing positioning devices for stainless steel shell processing, most of them can only simply clamp the outside during the processing. Not only is the clamping method single and not stable enough, but the inside of the shell lacks support, which easily causes external extrusion deformation. Utility Model Content

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 1-5As shown, a positioning device for stainless steel shell processing includes a shell 1 and a bottom plate 2 fixed to the bottom of the shell 1, a first movable plate 3 and a second movable plate 4 are respectively installed at the top two ends of the bottom plate 2, the tops of the first movable plate 3 and the second movable plate 4 are clamped with a clamping plate 7, and the clamping plate 7 can clamp and fix the outside of the stainless steel shell to facilitate subsequent processing, a first rack 5 is bolted to the inner bottom of the first movable plate 3, and a second rack 6 is bolted to the inner bottom of the second movable plate 4, the first rack 5 and the second rack 6 are slidably connected at the top of the bottom plate 2, an auxiliary block 13 is bolted to the top of the bottom plate 2, and a gear ring 8 is rotatably connected to the surface of the auxiliary block 13, and the gear ring 8 is respectively meshed with the first rack 5 and the second rack 6, The ring 8 is used in conjunction with the first rack 5 and the second rack 6. Under the action of the rotation of the gear ring 8, the first rack 5 and the second rack 6 will rotate accordingly, driving the first movable plate 3 and the second movable plate 4 to move back and forth with each other. A motion mechanism 9 is provided on the top of the auxiliary block 13. The motion mechanism 9 gives a power to the positioning device, which can drive the device to move as a whole. The motion mechanism 9 includes a fixed plate 91, which is bolted to the top of the auxiliary block 13. The fixed plate 91 is concave in design. Bearings 97 are clamped at both ends of the fixed plate 91. Both ends of the top of the fixed plate 91 are bolted to slide rails 92. The middle part of the fixed plate 91 is bolted to a bidirectional motor 93. The output shafts at both ends of the bidirectional motor 93 are installed with reciprocating screws 94 The middle part of the reciprocating screw 94 is threadedly connected with a slider 95. When the bidirectional motor 93 is used, the reciprocating screw 94 can rotate, and the slider 95 will move according to the rotation direction of the reciprocating screw 94. The bottom bolt of the slider 95 is connected with a slide seat 96, and the slide seat 96 is slidably connected with the slide rail 92. The slide rail 92 and the slide seat 96 are used together to assist the slider 95 to move left and right, and provide a support for the slider 95 to prevent the slider 95 from running off when moving. The other end of the reciprocating screw 94 is clamped on the inner ring of the bearing 97. The installation of the bearing 97 facilitates the rotation of the reciprocating screw 94 and makes the rotation of the reciprocating screw 94 smoother. A reciprocating mechanism 10 is arranged on the top of the slider 95. The reciprocating mechanism 10 is in the motion machine Under the action of the structure 9, the interior of the stainless steel shell can be expanded and clamped, which is convenient for the staff to process the shell, and the reciprocating mechanism 10 can move the first movable plate 3 and the second movable plate 4 while expanding and clamping the interior of the stainless steel shell, so that the positioning device can clamp and fix the inside and outside of the stainless steel shell together. A locking mechanism 11 is provided on the inner side of the shell 1. The setting of the locking mechanism 11 can fix the output shafts at both ends of the bidirectional motor 93 to avoid the reciprocating screw rod 94 from rotating during clamping, affecting the positioning and clamping effect of the shell. The top bolt of the shell 1 is connected with a bracket 12, which can support the shell to prevent the shell from falling, and it is also convenient for the device to position and clamp the shell.

[0024] The auxiliary block 13 includes a support plate 101, which is bolted to the top of the slider 95. The top of the support plate 101 is of arc-shaped design. A rack rod 103 is welded to the outside of the support plate 101. A silicone pad 102 is installed on the outside of the support plate 101. The silicone pad 102 can increase the friction of the support plate 101 and expand and clamp the inside of the shell. Gear 105 is rotatably connected to both ends of the top of the fixed plate 91. Rack rod 2 104 is welded to the inner side of the first movable plate 3 and the second movable plate 4. Gear 105 is respectively meshed with rack rod 103 and rack rod 2 104. When the slider 95 moves, the top support plate 101 drives rack rod 103 to move. When moving, gear 105 rotates to make rack rod 2 104 drive rack rod 2 104 to move.

[0025] The locking mechanism 11 includes a gear 114, which is welded to the output shaft surfaces at both ends of the bidirectional motor 93. A groove 111 is provided inside the shell 1, and a cylinder 113 is installed at both ends of the inner wall of the groove 111. The piston rod of the cylinder 113 is bolted with a half gear 112. When the cylinder 113 is used, the half gear 112 will move back and forth, which can engage with the gear 114 to avoid jamming. The reciprocating screw 94 can also rotate to affect the positioning and clamping effect of the shell, and the half gear 112 is engaged with the gear 114.

[0026] It is worth noting that the technical features such as the bidirectional motor 93 and the cylinder 113 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: when in use, place the stainless steel shell on the bracket 12 of the device, start the bidirectional motor 93, the output shafts at both ends drive the reciprocating screw rod 94 to rotate, and the slider 95 starts to move. While moving, the top support plate 101 and the rack rod 103 move in the same direction together, and the top silicone pad 102 and the support plate 101 will slowly approach the inside of the shell to achieve a clamping effect. The gear 105 will rotate under the influence of the rack rod 103. During rotation, the rack rod 2 104 and the first rack 5 move in the opposite direction, driving the first moving plate 3 to clamp and fix the shell. Similarly, the second rack 6 and the second moving plate 4 also move in the opposite direction to clamp and fix the outside. The inside of the shell is clamped, the clamping is more stable, and deformation is avoided. When the shell is fixed, the cylinder 113 is started to drive the half gear 112 to mesh with the gear 2 114, so as to achieve the effect of clamping and fixing the reciprocating screw rod 94. The device is particularly suitable for clamping and processing arc-shaped shells.
