Description

Technical Field

[0001] The utility model belongs to the field of positioning pins, and in particular relates to a positioning pin device capable of preventing aluminum chips from being stuck. Background Art

[0002] In the machining industry, precise fixation of workpieces is not only one of the important factors to ensure machining quality and efficiency, but is also directly related to the performance and safety of the final product.

[0003] Traditional workpiece securing methods typically rely on locating pins to achieve precise positioning. However, in actual machining, especially when processing materials prone to generating fine metal shavings, such as aluminum and copper, a common problem arises: metal shavings (especially aluminum shavings) can become lodged in the locating pins, leading to inaccurate positioning and, in turn, affecting machining precision and product yield. Existing locating pins are often fixed in design. When aluminum shavings generated during machining enter the gap between the locating pins and the workpiece, the workpiece cannot be properly positioned. This situation not only requires frequent machine downtime to clean the locating pins, but also causes interruptions in machining, severely impacting production efficiency. Utility Model Content

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3 As shown, the utility model is a positioning pin 50 device that can prevent aluminum chips from getting stuck, comprising: a tooling plate 2, on which a profiling table 20 is arranged, the profiling table 20 is used to place the workpiece 1 to be processed; a support member 3 and a pressing member 4, which are arranged on the tooling plate 2 and are equidistantly distributed in a ring shape at the periphery of the profiling table 20, the support member 3 is used to place the workpiece 1 in a horizontal posture, and fix the workpiece 1 on the tooling plate 2 through the pressing member 4; a positioning block 5, which is arranged on the tooling plate 2 and passes through the workpiece 1, and an elastic member and a positioning pin 50 are provided in the positioning block 5, and the elastic member is sleeved on the positioning pin 50, so that both ends of the positioning pin 50 can be retracted or extended relative to the positioning block 5 to eliminate the positioning error of the aluminum chips on the workpiece 1.

[0027] The workpiece 1 in this embodiment has a plurality of through grooves (not marked in the figure) formed inside, such as Figures 1 to 3As shown, when the worker places the workpiece 1 to be processed on the profiling table 20, the profiling table 20 is designed to match the shape of the workpiece 1, so as to achieve the effect of initial positioning of the workpiece 1 before processing; at the same time, the support member 3 can assist the workpiece 1 in being placed in a horizontal position, so as to prevent the workpiece 1 from being tilted and affecting the overall processing quality, and also provide a guarantee for the stability of the positioning pin 50 on the positioning block 5 when it abuts against the inner wall of the workpiece 1. It is worth noting that since the positioning block 5 is provided with an elastic member (not shown in the figure, it can be other elastic members such as a return spring, a torsion spring, etc.) sleeved on the positioning pin 50, and the positioning pin 50 is provided, In the initial state, both ends extend out of the positioning block 5. Therefore, even if there are aluminum chips remaining on the workpiece 1 or the positioning pin 50, when the end of the positioning pin 50 is against the inner wall of the workpiece 1, the positioning pin 50 will inevitably be squeezed and contracted inward due to the aluminum chips. In other words, by cooperating with the elastic member to give way, the positioning pin 50 is ensured to accurately position the workpiece 1, avoiding the fixed positioning pin 50 from affecting the accuracy of the workpiece 1 positioning due to the residual aluminum chips, and also preventing the fixed positioning pin 50 from squeezing the aluminum chips and causing damage to the workpiece 1. After the workpiece 1 is pressed and fixed, the machine tool can start processing the workpiece 1. It can be seen that the positioning pin 50 device cleverly uses the elastic member to give the positioning pin 50 the ability to automatically adjust, effectively solving the problem that the traditional positioning pin 50 is easily affected by the positioning accuracy of the aluminum chips and the frequent shutdown to clean the positioning pin 50, ensuring the smoothness and stability of the workpiece 1 throughout the entire processing process.

[0028] Preferably, if Figure 3 As shown, in this embodiment, the end of the locating pin 50 is also formed with an arc-shaped pressing surface 500. During the positioning process, the arc-shaped pressing surface 500 can ensure that the locating pin 50 is accurately positioned with the workpiece 1 while reducing the contact area with the iron chips, thereby effectively avoiding the workpiece 1 from being affected by the aluminum chips and causing damage to its own quality.

[0029] Further, if Figure 1 As shown, in this embodiment, at least two positioning blocks 5 are provided (two positioning blocks 5 are taken as an example in this embodiment). When the workpiece 1 is placed on the profiling table 20, the two positioning blocks 5 respectively pass through two through slots (not shown in the figure) on the workpiece 1, and the positioning pins 50 in the two adjacent positioning blocks 5 are movably pressed against the two sides of the inner wall of the workpiece 1, thereby better resisting the interference of external aluminum chips and ensuring that the positioning of the workpiece 1 is not affected during the processing.

[0030] The support member 3 includes a support block 30 and a connecting hole 31 arranged inside it. A through hole 21 is provided on the tooling plate 2. The connecting hole 31 can be interconnected with the through hole 21 when the support block 30 is placed on the tooling plate 2, so that the locking member can pass through and fix the support block 30 on the tooling plate 2.

[0031] like Figures 1 to 3 As shown, when the workpiece 1 is placed on the profiling table 20, the circumference of the workpiece 1 is exactly on the three support blocks 30 in this embodiment. The three support blocks 30, which are evenly spaced in a circular pattern, can effectively provide a stable support for the workpiece 1, thereby ensuring the stability of the workpiece 1 during processing. In addition, the support blocks 30 are detachably connected to the through holes 21 on the tooling plate 2 using the connection holes 31. When the upper end surface of the support block 30 becomes worn or damaged, the support block 30 can be removed from the tooling plate 2 using a locking member, allowing for replacement of a new support block 30 to ensure the stability of the positioning pin 50 device, providing convenience for subsequent maintenance and replacement. It should be noted that in this embodiment, the connection holes 31 can be threaded holes, and the locking members can be replaced by screws, screws, or other connecting components.

[0032] The clamping member 4 includes: a driving member 40, which is arranged at the bottom of the tooling plate 2, and the driving end of the driving member 40 passes through the tooling plate 2; a base plate 41 and a clamping block 42, the base plate 41 is installed on the tooling plate 2, the clamping block 42 is hinged to the driving end of the driving member 40, and a connecting plate 43 is hinged between the clamping block 42 and the base plate 41, so that when the driving member 40 is driven, it can drive the clamping block 42 to approach or move away from the workpiece 1.

[0033] Further, if Figure 2 As shown, when the workpiece 1 is accurately positioned, the driving end of the driving member 40 can move along Figure 2 Move vertically upward. During this process, the clamping block 42 can rotate relative to the connecting plate 43, so that the end of the clamping block 42 away from the driving end approaches and presses against the upper end face of the workpiece 1, providing a guarantee for the stability of the workpiece 1 during subsequent machining. The overall structure is relatively simple and easy to operate, which effectively saves the work efficiency when positioning and clamping the workpiece 1.

[0034] Preferably, a stepped seat 200 is also formed on the profiling table 20 in this embodiment. During the placement of the workpiece 1, the middle position of the workpiece 1 can be movably engaged in the stepped seat 200, thereby achieving a pre-positioning effect on the placement of the workpiece 1, and providing a guarantee for the accuracy of subsequent further positioning and pressing of the workpiece 1.

[0035] A positioning groove 22 is also provided on the tooling plate 2, a positioning hole 220 is provided in the positioning groove 22, a locking hole 51 is provided in the positioning block 5, and the positioning block 5 is movably inserted in the positioning groove 22 so that the locking hole 51 is aligned with the positioning hole 220 and connected to each other.

[0036] like Figure 3As shown, the installation of the positioning block 5 is the same as the installation principle of the above-mentioned support block 30, that is, the positioning block 5 is inserted into the positioning groove 22 to limit the position of the positioning block 5 on the tooling plate 2, thereby ensuring that the locking hole 51 can be accurately aligned with the positioning hole 220 and connected to each other, so that screws, screws and other connecting parts can fix the positioning block 5 on the tooling plate 2. This structure is also easy to operate and provides convenience for subsequent maintenance and replacement operations.

[0037] It should be noted that the driving member 40 in this embodiment can be replaced by other driving devices such as hydraulic drive, cylinder drive, etc.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0040] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
