Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a workpiece positioning device for equipment processing. Background Technology

[0002] Common machining equipment processes materials by means of material removal and non-material removal. Material removal methods mainly include drilling, milling, and grinding, while non-material removal methods mainly include bending. Regardless of the method, such equipment requires a positioning structure during processing, and the positioning method of such positioning structure is mainly clamping.

[0003] Currently, common positioning structures mainly include a base plate and two clamping plates located on the base plate. The two clamping plates move in opposite directions under the drive of the drive component, and then clamp the workpiece (column, plate, shell, etc.) between them. Due to the different structures and types of workpieces, in order to improve the clamping fit, clamping plates that are adapted to the shape and structure of the workpiece are usually set. However, since the clamping plates and the displacement components that drive them to move are in a fixed installation state (such as bolt fastening connection, welding, etc.), different clamping structures need to be changed when switching to process workpieces with other structures. The replacement method is usually manual disassembly and replacement, which is time-consuming and labor-intensive, and thus greatly reduces production efficiency.

[0004] Therefore, this utility model provides a workpiece positioning device for equipment processing. Utility Model Content

[0007] Furthermore, the middle part of the back of the grooved plate is fixedly connected to one end of the rotating shaft, and positioning shafts near the opening are fixedly connected to both sides inside the grooved plate. The positioning shafts are sleeved inside the rotating sleeve and the two are connected by bearings.

[0008] Furthermore, the outer peripheral wall of the rotating sleeve is welded with ear plates located at both ends. The two sides of the rotating sleeve are respectively provided with ear plates and mounting plates. The locking structure includes a pin, a limiting hole and a positioning hole. The positioning hole passes through one side of the longitudinal plate of the slotted plate. The limiting hole is opened on one side of the ear plate. The pin is inserted into and engaged with both the limiting hole and the positioning hole.

[0009] Furthermore, the locking structure includes an angle plate and a spring. One end of the angle plate is welded to the outer side of the longitudinal plate. A retaining ring is fixedly sleeved on the pin between the angle plate and the longitudinal plate. A spring is sleeved on the pin between the angle plate and the retaining ring.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a workpiece positioning device for equipment processing, including a base 1 and two movable seats 2 located on the base 1. A guide rail is fixedly installed on the upper end surface of the base 1. A slide seat adapted to the guide rail is welded to the bottom of the movable seat 2. A rotating shaft 3 is installed through the two movable seats 2. The rotating shafts 3 on the two movable seats 2 are coaxial. A grooved plate 4 is fixedly connected to the opposite ends of the rotating shafts 3 on the two movable seats 2. Specifically, the middle part of the back of the grooved plate 4 is fixedly connected to one end of the rotating shaft 3. When the rotating shaft 3 rotates, it can drive the grooved plate 4 to rotate. A rotating sleeve 5 is provided inside the opening of the grooved plate 4. In a preferred embodiment, positioning shafts near the opening are fixedly connected to both sides inside the grooved plate 4. The positioning shafts are sleeved in the rotating sleeve 5 and the two are connected by bearings. At least two mounting plates 6 are arranged around the outer periphery of the rotating sleeve 5. In this embodiment, there are three mounting plates 6, which are evenly arranged around the outer periphery of the rotating sleeve 5. The mounting plates 6 are fixedly connected to the outer wall of the rotating sleeve 5 through the support plate 7. The mounting plate 6 has mounting holes 61 on its surface. The mounting holes 61 can be fixedly connected to clamping plates of different specifications by bolts. Specifically, one mounting plate 6 corresponds to one specification of clamping plate. When the rotating sleeve 5 rotates, it can drive one of the clamping plates to the clamping position. When the rotating shaft 3 rotates, it can adjust the angle of the clamping plate, so that the workpiece can be processed after rotating to a certain angle.

[0022] Among them, a locking structure 8 is provided between the groove plate 4 and the rotating sleeve 5. The function of the locking structure 8 is to fix the clamping plate in the clamping position, specifically to lock the rotating sleeve 5.

[0023] Specifically, the outer peripheral wall of the rotating sleeve 5 is welded with ear plates 51 located at both ends. The two sides of the rotating sleeve 5 are respectively provided with ear plates 51 and mounting plates 6. The locking structure 8 includes a pin 81, a limiting hole 82 and a positioning hole 83. The positioning hole 83 passes through one side of the longitudinal plate 41 on the slotted plate 4. The limiting hole 82 is opened on one side of the ear plate 51. The pin 81 is inserted into both the limiting hole 82 and the positioning hole 83. Specifically, when a mounting plate 6 is in the clamping position, the limiting hole 82 on the corresponding ear plate 51 and the positioning hole 83 on the longitudinal plate 41 are aligned. When the pin 81 is inserted into the current positioning hole 83 and the limiting hole 82, the current ear plate 51 can be locked, thereby locking the rotating sleeve 5.

[0024] Furthermore, the locking structure 8 includes an angle plate 84 and a spring 85. One end of the angle plate 84 is welded to the outer side of the longitudinal plate 41. A retaining ring 811 is fixedly sleeved on the pin 81 between the angle plate 84 and the longitudinal plate 41. A spring 85 is sleeved on the pin 81 between the angle plate 84 and the retaining ring 811. The function of the spring 85 is to apply an elastic thrust to the pin 81 in the direction of movement toward the adjacent ear plate 51, which has the function of preventing the pin 81 from loosening. The positioning hole 83 is a conical hole structure with the large end facing the adjacent longitudinal plate 41. One end of the pin 81 is a conical head that matches the positioning hole 83. After the conical head enters the positioning hole 83 of the conical hole structure, the two will fit tightly together, thereby improving the positioning accuracy of the pin 81 on the ear plate 51.

[0025] In this embodiment, the pin 81 and the positioning hole 83 are transitionally fitted, thereby eliminating the gap between the pin 81 and the positioning hole 83. It should be noted that the pin 81 can rotate relative to the positioning hole 83. One side of the corner plate 84 is provided with a through hole 841 that is clearance-fitted with the pin 81. The other end of the pin 81 is welded with an L-shaped rod 812. After pulling the pin 81 outward, it is twisted so that the other end of the L-shaped rod 812 abuts against the outer wall of the corner plate 84. During this process, the spring 85 is compressed. At this time, the conical head on the pin 81 will disengage from the limiting hole 82. Thus, the rotating sleeve 5 can be freely rotated to switch different mounting plates 6 to the clamping position. After switching, the pin 81 is rotated so that the other end of the L-shaped rod 812 is suspended and the pin 81 is released. At this time, the conical head on the pin 81 will enter the limiting hole 82 on the current ear plate 51, thereby locking the rotating sleeve 5.

[0026] In this embodiment, a support sleeve 21 is fixedly connected to the movable seat 2. The support sleeve 21 is sleeved on the outside of the rotating shaft 3 and a bearing is provided between the two. The purpose of this arrangement is to prevent the rotating shaft 3 from shaking when it rotates relative to the movable seat 2. A gear 31 is fixedly sleeved on the other end of the rotating shaft 3. The gear 31 is used to connect with an external drive mechanism with a toothed structure, so as to control the rotation of the rotating shaft 3 through meshing.

[0027] Specifically, a drive shaft can be rotatably connected above the base 1, and two gear sleeves that mesh with gears 31 on the two rotating shafts 3 can be fixedly fitted on the drive shaft. When the drive shaft is rotated, the two rotating shafts 3 can be synchronously driven to rotate synchronously through the gears 31. In specific implementation, two positioning plates that are rotatably connected to both ends of the drive shaft are welded on the base 1, and a servo motor is installed on one of the positioning plates. The output shaft of the servo motor is fixedly connected to one end of the drive shaft, which facilitates the control of the rotating shaft 3.

[0028] In this embodiment, a lead screw located below two movable seats 2 is rotatably connected to the top of the base 1 via two upright plates. Two threaded sleeves with different internal thread directions are screwed onto the lead screw. The two threaded sleeves are fixedly connected to the bottom walls of the two movable seats 2 via connecting plates. Thus, when the lead screw is rotated, the two movable seats 2 can be controlled to move synchronously in opposite directions. In use, a servo motor 2 is fixedly installed on one side of one of the upright plates. The output shaft of the servo motor 2 is fixedly connected to one end of the lead screw, which facilitates motorized control of the lead screw rotation. A dust cover is fitted on the lead screw to prevent debris from entering the spiral groove on the lead screw.

[0029] Working principle: Before use, clamps of different specifications are fixedly installed on the outside of each mounting plate 6 with bolts. Select the appropriate clamp according to the specifications of the workpiece and place it in the clamping position. When it is necessary to switch clamps, manually pull the L-shaped rod 812 outward and then rotate it so that the free end of the L-shaped rod 812 abuts against the outside of the corner plate 84. At this time, the spring 85 is compressed by the retaining ring 811 and the conical head leaves the limiting hole 82. Manually push the mounting plate 6 so that the required clamp is in the clamping position. Then rotate the L-shaped rod 812 and release it. The spring 85 extends and pushes the pin 81 through the retaining ring 811. The conical head at one end of the pin 81 enters the limiting hole 82. At this time, the current ear plate 51 is locked, which in turn locks the rotating sleeve 5. Then control the two moving seats 2 to move synchronously in opposite directions. At this time, the clamps on the two mounting plates 6 will clamp the corresponding workpiece to achieve the positioning processing of the workpiece of the current specification.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
