Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooling fixtures, in particular to a firmly connected plastic tooling fixture. Background Art
[0002] Tooling jigs are often needed in industrial operations. Tooling jigs include clamps, which are usually used to assist in controlling position or movement. After searching, the Chinese patent authorization number CN218082288U discloses a firmly connected plastic tooling jig. Although the firmly connected plastic tooling jig is equipped with a lubrication mechanism, the lubricating oil is injected through the oil filling port, and the ball is contaminated with the lubricating oil when rolling through the opening, making the ball roll more smoothly. However, due to the fixed shape of the clamping mechanism of the plastic tooling jig, it cannot fully contact when clamping special-shaped or rectangular objects, thereby reducing the clamping firmness. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a firmly connected plastic tooling fixture, which solves the problem in the background technology that the existing plastic tooling fixture has a fixed shape of the clamping mechanism, which cannot fully contact when clamping special-shaped or rectangular objects, thereby reducing the clamping firmness.
[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a firmly connected plastic tooling fixture, comprising a device body, a rotating shaft, a sliding block, a telescopic block, a connecting head and a rotating head, a motor frame is welded at one end of the device body, the top of the motor frame is connected to the driving motor by bolts, two driving motors are provided, the two driving motor output ends are externally sleeved with rotating shafts, the other ends of the rotating shafts are externally rotatably connected to the other end of the device body, the external part of the rotating shafts is threadedly connected to the connecting blocks, the connecting blocks are distributed on both sides of the sliding block, and the connecting blocks are welded to the surface of the sliding block, the interior of the sliding block is a hollow structure, and one end of the interior of the sliding block is filled with steel balls, a telescopic block is arranged at the other end of the sliding block, one end of the telescopic block is welded to one end of the connecting head, and a rotating head is provided at the other end of the connecting head.
[0005] Preferably, two rotating shafts are provided, and thread structures are distributed on the surfaces of both ends of the rotating shaft, and the threads at both ends of the rotating shaft are in opposite directions, so that the connecting blocks at both ends of the rotating shaft can move in opposite directions while the rotating shaft rotates.
[0006] Preferably, a limit block is welded on the inner wall of the sliding block, and the limit block is in sliding contact with a strip-shaped groove on the surface of the telescopic block. The limit block is conducive to limiting the stroke of the telescopic block, thereby preventing the limit block from sliding out of the sliding block.
[0007] Preferably, the telescopic blocks are arranged in a straight line and in regular pattern, and the telescopic blocks are in sliding contact with each other. Providing a plurality of telescopic blocks is beneficial for fully contacting the surface of the special-shaped object.
[0008] Preferably, one end of the connecting head is rotatably connected to the rotating head, and limiting rods are welded on the top and bottom of the connecting head. There is a gap between one end of the limiting rod and the rotating head. The two limiting rods are helpful in limiting the rotation angle of the rotating head.
[0009] Preferably, a protective pad is bonded to the outside of the rotating head, and the protective pad is made of flexible rubber material. The rubber material helps to prevent the rotating head from directly contacting the surface of the object and causing damage.
[0010] The utility model provides a plastic tooling fixture with a firm connection. It has the following beneficial effects:
[0011] (1) A plastic tooling fixture with a firm connection. When the device is used, an object is placed between two sliding blocks, and then the rotating shaft is driven to rotate by a driving motor. When the rotating shaft rotates, it can drive the two sliding blocks to move toward the object, so that the protective pad at one end of the rotating head contacts the surface of the object. At the same time, the steel ball at the other end of the telescopic block flows inside the sliding block until one end of the telescopic block imitates the outer contour of the object, so that each protective pad can contact the surface of the object, which is conducive to sufficient contact and fixation when clamping special-shaped objects.
[0012] (2) This is a firmly connected plastic tooling fixture. When the surface of an object is uneven, when the rubber pad contacts the surface of the object, the rotating head will adaptively rotate along with the surface of the object, so that the protective pad on one side of the rotating head can fully fit the surface of the object.
[0013] This solves the problem that the existing plastic tooling jigs and fixtures cannot fully contact special-shaped or rectangular objects due to the fixed shape of the clamping mechanism, thereby reducing the clamping firmness. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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.
[0021] Embodiment 1:
[0022] See also Figure 1-5 A plastic tooling fixture with a firm connection includes a device body 1, a rotating shaft 4, a sliding block 6, a telescopic block 9, a connecting head 10 and a rotating head 11. A motor frame 2 is welded at one end of the device body 1. The top of the motor frame 2 is connected to the driving motor 3 by bolts. Two driving motors 3 are provided. The output ends of the two driving motors 3 are externally sleeved with a rotating shaft 4. The other end of the rotating shaft 4 is externally rotatably connected to the other end of the device body 1. The external part of the rotating shaft 4 is threadedly connected to the connecting block 5. The connecting blocks 5 are distributed on both sides of the sliding block 6, and the connecting blocks 5 are welded to the surface of the sliding block 6. The interior of the sliding block 6 is a hollow structure, and one end of the interior of the sliding block 6 is filled with steel balls 7. The other end of the sliding block 6 is provided with a telescopic block 9. One end of the telescopic block 9 is connected to the connecting head 10. The ends are welded, and a rotating head 11 is provided at the other end of the connecting head 10. Two rotating shafts 4 are provided, and threaded structures are distributed on the surfaces of both ends of the rotating shaft 4, and the threads at both ends of the rotating shaft 4 are in opposite directions. A limiting block 8 is welded on the inner wall of the sliding block 6, and the limiting block 8 is in sliding contact with the strip-shaped groove on the surface of the telescopic block 9. When the rotating shaft 4 rotates, it can drive the two sliding blocks 6 to move toward the object, so that the protective pad 12 at one end of the rotating head 11 contacts the surface of the object, and the steel ball 7 at the other end of the telescopic block 9 flows inside the sliding block 6 until one end of the telescopic block 9 imitates the outer contour of the object, so that each protective pad 12 can contact the surface of the object, which is beneficial to fully contact and fix when clamping special-shaped objects.
[0023] Embodiment 2:
[0024] The telescopic blocks 9 are arranged in a straight line and in regular contact with each other. One end of the connecting head 10 is rotatably connected to the rotating head 11, and a limiting rod 13 is welded on the top and bottom of the connecting head 10. There is a gap between one end of the limiting rod 13 and the rotating head 11. A protective pad 12 is bonded to the outside of the rotating head 11. The protective pad 12 is made of flexible rubber material. When the surface of the object is uneven, when the rubber pad contacts the surface of the object, the rotating head 11 will adaptively rotate with the surface of the object, so that the protective pad 12 on one side of the rotating head 11 can fully fit the surface of the object. The rubber protective pad 12 is helpful to avoid damage caused by direct rigid contact between the rotating head 11 and the surface of the object.
[0025] Working principle: When the device is in use, the object is placed between the two sliding blocks 6, and the rotating shaft 4 is driven to rotate by the driving motor 3. When the rotating shaft 4 rotates, it can drive the two sliding blocks 6 to move toward the object, so that the protective pad 12 at one end of the rotating head 11 contacts the surface of the object. At the same time, the steel ball 7 at the other end of the telescopic block 9 flows inside the sliding block 6 until one end of the telescopic block 9 imitates the outer contour of the object, so that each protective pad 12 can contact the surface of the object, which is beneficial for fully contacting and fixing the special-shaped objects when clamping. When the surface of the object is uneven, when the rubber pad contacts the surface of the object, the rotating head 11 will adaptively rotate with the surface of the object, so that the protective pad 12 on one side of the rotating head 11 can fully fit with the surface of the object. The rubber protective pad 12 is helpful to avoid damage caused by direct rigid contact between the rotating head 11 and the surface of the object.
