Description

Technical Field

[0001] This utility model relates to the field of product processing technology, and in particular to a snap-in slider symmetrical pressing and positioning device. Background Technology

[0002] Precision product manufacturing is an important guarantee for driving product transformation and upgrading. Based on the structural characteristics of the product and the technical parameters required for processing, the manufacturing plant needs to customize or manufacture equipment that is suitable for the product being processed. Among them, the product clamping and positioning device is indispensable.

[0003] Existing CNC machining centers generally use a unidirectional clamping mechanical structure for product clamping and positioning devices. This clamping structure is only suitable for products with regular shapes and cannot stably process products with irregular shapes. Therefore, it is still necessary to improve the structure of the existing clamping and positioning devices to adapt to products with different shapes and structures. Summary of the Invention

[0004] The purpose of this utility model is to provide a snap-in slider symmetrical clamping and positioning device to overcome the shortcomings and deficiencies in product processing and to achieve initial positioning, clamping and pressing functions for products with irregular shapes.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A snap-fit ​​slider symmetrical clamping and positioning device includes two insert blocks, two cylinders, and a base. The insert blocks and cylinders are symmetrically fixed on the base, with the insert blocks located inside the cylinders. The outer end of a connector is fixedly connected to a push rod inside the cylinder, and the inner end of the connector is rotatably connected to the insert block via a pin. The insert blocks have elongated holes along the left-right direction. The base has two symmetrical slots on its left and right sides, with a pin groove in the middle of each slot along the front-back direction. A positioning pin is located in the pin groove. The insert blocks are embedded in the slots and can move left and right along the slots. The insert blocks are limited to sliding by cooperating with the positioning pins through the elongated holes. A key protrudes from the inner side of the insert blocks and is inserted into holes on the left and right side walls of the workpiece. Two positioning elements are vertically penetrating through the middle of the base, and these positioning elements cooperate with the mounting holes on the left and right sides of the workpiece for positioning.

[0007] Furthermore, the device includes a connector, the outer end of which is fixedly connected to the push rod inside the cylinder by a headless screw.

[0008] Furthermore, the upper end of the outer side of the insert block is provided with a lug, and the inner end of the connector and the lug are rotatably connected by a pin.

[0009] Furthermore, the device includes a cylinder fixing plate, and mounting grooves are symmetrically provided on the left and right sides of the base. The lower end of the cylinder fixing plate is fixed in the mounting groove, and the inner side of the cylinder fixing plate is fixedly connected to the outer side of the cylinder by bolts.

[0010] This utility model uses a cylinder to drive the insert block to initially clamp the workpiece from both sides. The long hole of the insert block is guided and limited by a pin, so that when the insert block moves horizontally to the limit position, it will flip inward through the hinge relationship with the cylinder, thereby pressing the upper end of the workpiece. It realizes the functions of initial positioning, clamping and pressing in one unit. It further prevents loosening after clamping special irregular shaped products and prevents the product from deforming during processing. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] This utility model discloses a snap-in slider symmetrical clamping and positioning device, applied to workpiece 1 of a subcontracted product, such as... Figure 1 As shown, the device specifically includes two insert blocks 2, two connectors 3, two cylinders 4, two cylinder fixing plates 5, and a base 6. The insert blocks 2 and cylinders 4 are symmetrically fixed on the base 6. The base 6 has symmetrical mounting grooves 15 on its left and right sides. The lower end of the cylinder fixing plate 5 is fixed in the mounting groove 15. The inner side of the cylinder fixing plate 5 is fixed to the outer side of the cylinder 4 by bolts.

[0019] Insert 2 is located inside cylinder 4. The outer end of connector 3 and the push rod inside cylinder 4 are fixedly connected by headless screw 16. The upper end of the outer side of insert 2 is provided with lug 14. The inner end of connector 3 and lug 14 are rotatably connected by pin 13.

[0020] like Figure 1 As shown, the insert 2 has an elongated hole 7 along the left and right direction, and the base 6 has two slots 9 symmetrically arranged on the left and right sides. The middle of the slot 9 has a pin groove 10 along the front and back direction, and a positioning pin 11 is provided in the pin groove 10. The insert 2 is embedded in the slot 9 and can move left and right along the slot 9. The insert 2 is limited to sliding through the long hole 7 and the positioning pin 11. The inner side of the insert 2 has a protruding key 12, which is inserted into the holes on the left and right side walls of the workpiece 1. The middle of the base 6 has two positioning pieces 8 running through it vertically. The positioning pieces 8 are positioned in conjunction with the mounting holes on the left and right sides of the workpiece 1.

[0021] This utility model device is an auxiliary product clamping and fixing device for machining centers, and the power source is pneumatic.

[0022] When in use, click the pneumatic switch. Since the two plugs 2 are connected to the push rods of the two cylinders 4 through the connector 3, and the elongated holes 7 of the plugs 2 are slidably connected to the positioning pins 11 on the base 6, the two cylinders 4 drive the two plugs 2 to move towards the center of the base 6 until the cylinders 4 stop. At this time, the two plugs 2 are a certain distance away from the positioning position of the workpiece 1 at the center of the base 6, and will not interfere with the placement of the workpiece 1.

[0023] like Figure 2 As shown, place workpiece 1 at the upper center of base 6, so that the two positioning holes of workpiece 1 are respectively locked into the heads of the two positioning parts 8. After placing workpiece 1, press the pneumatic switch again. The two insert blocks 2 move towards workpiece 1 from the left and right sides under the drive of the two cylinders 4. When the two insert blocks 2 move to the root of the long hole 7 and coincide with the surface of the positioning pin 11, the key 12 of the insert block 2 has been locked into the inside of workpiece 1. At this time, due to the obstruction of the positioning pin 11, the two insert blocks 2 can no longer move forward. Since the two insert blocks 2 and the two connectors 3 are connected by the pin 13 to form a lever cooperation, when the two cylinders 4 continue to move forward, the two insert blocks 2 are blocked by the positioning pin 11 and change the direction of movement, and turn inward to form downward pressure until the key 12 presses the left and right sides of workpiece 1 to stop the operation.

[0024] Finally, click the pneumatic switch, and the two inserts 2 will retract to the open position, allowing you to remove workpiece 1.

[0025] This completes one full operation.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
