Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment, and in particular relates to an adjustable quick-positioning handheld tool with reserved adjustment margin. Background Art

[0002] At present, most of the handheld metal parts embedded tooling designed according to the mold have fixed specifications and cannot be properly adjusted as the mold changes. Therefore, if the mold makes changes within a certain range of data, even if it is a millimeter-level change, it is impossible to use the handheld tooling with fixed specifications to adjust the embedded position of the embedded parts. Only by re-modifying the base plate can it continue to be used in conjunction. Re-modifying, producing, and testing the base plate will affect progress and efficiency, and the base plate may not be used subsequently.

[0003] In this regard, it is necessary to design a handheld tool that can be adjusted within a certain range for each company. Even if there is a position deviation after changing the mold, it can be readjusted and used directly to ensure efficiency and timeliness of use. Utility Model Content

[0006] Preferably, each of the push rods between the third assembly plate and the second assembly plate is further provided with a threaded push rod to assist in the relative positioning and movable connection between the third assembly plate and the second assembly plate.

[0007] Preferably, the push rod and the threaded push rod are both equipped with a pressing block for positioning and installation as required.

[0008] Preferably, the second assembly plate and the third assembly plate are each provided with a plurality of assembly holes for the push rod and the threaded push rod to connect the two in multi-point positioning, and the assembly holes of the second assembly plate and the assembly holes of the third assembly plate are opened on the same central axis on the basis of corresponding positions.

[0009] Preferably, the diameters of the assembly holes of the second assembly plate and the assembly holes of the third assembly plate are different.

[0010] Preferably, the diameters of the assembly holes on the second assembly plate and the third assembly plate should be larger than the actual diameters of the push rod and the threaded push rod.

[0011] Preferably, the push rod or threaded push rod can be inserted and positioned with the assembly hole in the form of an inscribed circle, a concentric circle or a circular ring.

[0012] Preferably, the embedded part fixing sleeve is assembled at the end of the push rod.

[0013] Compared with the prior art, the advantages of the present invention are: the present invention makes technical improvements to the handheld tooling for pre-embedding metal parts in the mold, and while retaining the basic structure and operating steps, improves the assembly holes of the push rod and its matching threaded push rod for fixing the pre-embedded part fixing sleeve, specifically, the assembly hole is expanded, that is, the diameters of the assembly holes on the second assembly plate and the third assembly plate must be larger than the actual diameters of the push rod and the threaded push rod, so that the push rod or the threaded push rod can be positioned and assembled in the assembly hole in the form of an inscribed circle, a concentric circle or a circular ring. Such an assembly method allows the push rod or the threaded push rod to be adjusted in position within a certain range, so that it can be positioned and pre-embedded in conjunction with different molds whose product sizes have been adjusted or molds with partial position deviations, avoiding the need to redesign and manufacture new handheld tooling to match new molds or problematic molds.

[0017] 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.

[0018] like Figures 1 to 3As shown, the utility model is an adjustable quick positioning handheld tool with reserved adjustment margin, and the utility model is composed of a pressing handle (1), a mold positioning needle (2), an embedded part fixing sleeve (3), a first assembly plate (4), a second assembly plate (5), a third assembly plate (6), a connecting shaft (7), a push rod (8) and a guide shaft (9).

[0019] The second assembly plate (5) is assembled between the first assembly plate (4) and the third assembly plate (6) through the cooperation of the connecting shaft (7), the push rod (8) and the guide shaft (9), and the push handle (1) is fixedly connected to the second assembly plate (5) after passing through the hole opened in the first assembly plate (4); the bottom of the third assembly plate (6) is provided with a positioning pin (10). Such a structure can ensure that the utility model can correspondingly and firmly place the embedded part fixing sleeve (3) into the embedded hole of the mold through the positioning pin (10), realize rapid positioning and avoid deviation. Of course, the push rod (8), the threaded push rod (11) and the positioning pin (10) of the utility model with the embedded part fixing sleeve (3) need to be adjusted according to the mold before work to ensure that the position of the positioning pin (10) and the center point of the push rod (8) are consistent with the assembly data of the corresponding mold.

[0020] In addition to the rapid positioning achieved by the positioning pin (10), the most important point of the utility model is that it has a reserved adjustment margin, that is, the assembly hole is expanded, which is reflected in that the diameter of the assembly hole on the second assembly plate (5) and the third assembly plate (6) must be larger than the actual diameter of the push rod (8) and the threaded push rod (11), so that the push rod (8) or the threaded push rod (11) can be inserted and positioned in the assembly hole in the form of an inscribed circle, a concentric circle or a ring. For details, please refer to Figure 3This assembly method allows the push rod (8) or the threaded push rod (11) to be adjusted in position within a certain range, so that it can be pre-positioned and embedded in different molds whose product dimensions have been adjusted or molds with partial position deviations, avoiding the need to redesign and manufacture new handheld tooling to match new molds or problematic molds. This method undoubtedly greatly improves efficiency and ensures the timeliness, versatility and practicality of the handheld tooling. In order to achieve the above-mentioned effect, each of the push rods (8) between the third assembly plate (6) and the second assembly plate (5) is also provided with a threaded push rod (11) to assist the positioning and movable connection between the third assembly plate (6) and the second assembly plate (5), and each of the push rods (8) and the threaded push rods (11) is provided with a pressure block (10) and a gasket for positioning and installation as required. By providing the pressure block (10) and the gasket, the push rods (8) and the threaded push rods (11) can be better assembled in a more stable position and can avoid the possibility of loosening or displacement caused by the up and down movement during operation. Such a setting can greatly improve the stability and practicality of the utility model and avoid the displacement of the push rod caused by multiple pressing in a short period of time, which requires re-fixing and affects the efficiency.

[0021] It should be further explained that the second assembly plate (5) and the third assembly plate (6) are each provided with a plurality of assembly holes for the push rod (8) and the threaded push rod (11) to connect the two in a multi-point positioning manner, and the assembly holes of the second assembly plate (5) and the assembly holes of the third assembly plate (6) are opened on the same central axis on the basis of corresponding positions. Such a design can ensure that even if the diameters of the assembly holes of the second assembly plate (5) and the assembly holes of the third assembly plate (6) are different, when the user presses the push handle (1), the second assembly plate (5) located between the first assembly plate (4) and the third assembly plate (6) can still move smoothly and vertically, thereby allowing the embedded fixing sleeve (3) provided at the bottom of the utility model to fall into the target hole of the mold without being damaged or offset.

[0022] The utility model has a simple and reasonable structure. While retaining the basic structure and operation steps, the assembly holes of the push rod (8) and the matching threaded push rod (11) for fixing the embedded part fixing sleeve (3) are improved. By opening the assembly holes with reserved adjustment margin, the matching with the molds with similar sizes can be realized, and the pressure block (10) is added to ensure its working stability. For example, different product molds with fine-tuned sizes or molds with partial position deviations can be adjusted within the range based on the assembly holes after the holes are expanded to ensure that the embedded parts can still be adjusted to obtain effective positioning to embed the embedded parts, avoiding the need to redesign and manufacture new handheld tooling to match the new mold or the problem mold. The operation is that when the mold is changed, the fastening bolts on the embedded part fixing sleeve (3) can be loosened, and then the mold positioning pin (2) is used to accurately position the new mold, and then the position of the embedded part fixing sleeve (3) and the mold inlay pin is adjusted, and then the fastening bolts are tightened to position and fix the embedded part fixing sleeve (3) that has changed position. This method undoubtedly greatly improves the efficiency and ensures the timeliness, versatility and practicality of the handheld tooling, and solves the limitation that the handheld tooling with fixed size cannot be adjusted.
