Description

Technical Field

[0001] This application relates to the field of molds, and more particularly to a positioning device. Background Technology

[0002] Currently, many workpieces need to be pre-clamped and positioned by a positioning device before processing, so that the machining tool can perform machining on the workpiece.

[0003] In related technologies, the positioning devices used in machining equipment can only clamp the bottom surface of the workpiece, resulting in unstable clamping of the workpiece. Utility Model Content

[0004] This application provides a positioning device to solve the problems mentioned above.

[0005] In a first aspect, this application provides a positioning device for fixing a workpiece to be processed. The top surface of the workpiece to be processed is provided with a recessed cavity. The positioning device includes: a base, a positioning plate, a first driving mechanism, and a mounting assembly. The base and the positioning plate are connected, and the first driving mechanism is disposed on the base. The mounting assembly is provided with at least two grooves that are adapted to the bottom surface of the workpiece to be processed. The positioning plate is provided with at least two locking blocks that are adapted to the recessed cavity on the side facing the mounting assembly. The first driving mechanism is used to push the mounting assembly closer to or away from the positioning plate so that the mounting assembly can switch between a fixed position and an installed position. When the mounting assembly is in the fixed position, the locking blocks are locked in the recessed cavity.

[0006] In some embodiments, a pressure sensor and a processor are also included. The pressure sensor is electrically connected to the processor and is disposed on the positioning plate. The pressure sensor is configured to sense the pressure when the positioning plate approaches the mounting component, so that when the pressure reaches a preset value, the processor drives the first drive mechanism to stop working.

[0007] In some embodiments, a first drive mechanism is used to push the mounting assembly to move along a first direction, and at least two grooves are spaced apart along a second direction, with the first and second directions being perpendicular to each other.

[0008] In some embodiments, the number of locking blocks is two, and the number of grooves is four. Two of the four grooves are spaced apart along the second direction, and the other two grooves are spaced apart along the third direction. The second direction and the third direction intersect.

[0009] In some embodiments, a rotary cylinder is also included, which is disposed on the mounting assembly and is used to drive the mounting assembly to rotate.

[0010] In some embodiments, the locking block includes an annular seat, the outer wall of which abuts against the inner wall of the recessed cavity when the mounting assembly is in a fixed position.

[0011] In some embodiments, the positioning plate is provided with an inlet at a position corresponding to the annular seat.

[0012] In some embodiments, the mounting assembly includes a mounting plate and at least two mounting bases, the at least two mounting bases being adapted to at least two recesses, the recesses being disposed on corresponding mounting bases, and the mounting bases being detachably connected to the mounting plate.

[0013] In some embodiments, the first drive mechanism includes a pneumatic cylinder or a hydraulic cylinder.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] The positioning device provided in this application embodiment ensures that the workpiece will not move or shift during processing, thereby improving processing accuracy and consistency. Secondly, by engaging the locking block within the recessed cavity of the workpiece, the fixing effect is further enhanced, preventing loosening or detachment due to vibration or external force during processing. Furthermore, because the workpiece is more firmly and precisely fixed during processing, the scrap rate caused by workpiece movement or positional deviation is reduced, improving product pass rate and quality.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] Currently, many workpieces need to be pre-clamped and positioned by a positioning device before processing, so that the machining tool can perform machining on the workpiece.

[0039] In related technologies, the positioning devices used in machining equipment can only clamp the bottom surface of the workpiece, resulting in unstable clamping of the workpiece.

[0040] See Figures 1 to 5 In order to solve the technical problems existing in the related technologies, this application provides a positioning device 1, which is used to fix the workpiece 2 to be processed and realize the positioning function of the workpiece 2.

[0041] See Figure 2 and Figure 3 The top surface 201 of the workpiece 2 is provided with a recessed cavity 203.

[0042] The positioning device 1 includes a base 10, a positioning plate 20, a first drive mechanism 30, and a mounting assembly 40. The base 10 and the positioning plate 20 are connected, and the first drive mechanism 30 is disposed on the base 10. The mounting assembly 40 is provided with at least two grooves 41 that are adapted to the bottom surface 202 of the workpiece 2 to be processed. The positioning plate 20 is provided with at least two locking blocks 50 that are adapted to the recessed cavity 203 on the side facing the mounting assembly 40. The first drive mechanism 30 is used to push the mounting assembly 40 closer to or further away from the positioning plate 20, so that the mounting assembly 40 switches between a fixed position and an installed position. When the mounting assembly 40 is in the fixed position, the locking blocks 50 are locked in the recessed cavity 203.

[0043] For example, the seat 10 and the positioning plate 20 are connected to form a rectangular seat 10, and the rectangular seat 10 defines a mounting cavity with openings on opposite sides, and the first drive mechanism 30 and the mounting assembly 40 are disposed in the mounting cavity.

[0044] It should be noted that at least two grooves 41 can be two, three, or four, etc., and no limitation is made here.

[0045] According to the positioning device 1 of this application embodiment, when the workpiece 2 needs to be processed, the first driving mechanism 30 drives the mounting assembly 40 to move to the mounting position. At this time, the bottom surface 202 of the workpiece 2 is locked in the groove 41 of the mounting assembly 40. Then, the first driving mechanism 30 drives the mounting assembly 40 from the mounting position to the fixed position. At this time, the locking block 50 on the positioning plate 20 locks into the recessed cavity 203 of the workpiece 2. With this configuration, when the mounting assembly 40 is in the fixed position, the bottom surface 202 and the top surface 201 of the workpiece 2 are firmly fixed, ensuring that the workpiece 2 will not move or shift during processing, thereby improving the accuracy and consistency of processing. Secondly, by locking the locking block 50 into the recessed cavity 203 of the workpiece 2, the fixing effect of the workpiece 2 is further enhanced, avoiding loosening or falling off due to vibration or external force during processing. Furthermore, because the workpiece 2 is more firmly and precisely fixed during the processing, the scrap rate caused by the movement or positional deviation of the workpiece 2 is reduced, thereby improving the product qualification rate and quality.

[0046] Furthermore, since the conversion between the installation position and the fixed position of the workpiece 2 is automatically completed by the first drive mechanism 30, the number of manual operation steps is reduced, the processing efficiency is improved, and the time and error of manual intervention are reduced.

[0047] In some embodiments, this application further includes a pressure sensor 60 and a processor. The pressure sensor 60 is electrically connected to the processor and is disposed on the positioning plate 20. The pressure sensor 60 is configured to sense the pressure when the positioning plate 20 approaches the mounting assembly 40, so that when the pressure reaches a preset value, the processor drives the first drive mechanism 30 to stop working. In this configuration, the distance between the mounting assembly 40 and the positioning plate 20 is related to the pressure received by the pressure sensor 60. The processor can accurately control the first drive mechanism 30 to stop working based on the pressure detected by the pressure sensor 60, ensuring that the force for fixing the workpiece 2 is moderate and avoiding excessive tightness or looseness. Secondly, the preset pressure value can be adjusted according to the material and shape of the workpiece 2 to avoid damage to the workpiece 2 due to excessive pressure, which is especially suitable for fragile or delicate workpieces.

[0048] It should be noted that the pressure sensor 60 can be a capacitive pressure sensor 60, a strain gauge pressure sensor 60, a piezoelectric pressure sensor 60, a piezoresistive pressure sensor 60, or an inductive pressure sensor 60, and no limitation is made here.

[0049] In some embodiments, see Figure 1 The first drive mechanism 30 is used to push the mounting component 40 to move along the first direction X, and at least two grooves 41 are spaced apart along the second direction Y, with the first direction X and the second direction Y being perpendicular to each other.

[0050] In this embodiment, the distance between the mounting component 40 and the positioning plate 20 is equal everywhere, so that when the first driving mechanism 30 pushes the mounting component 40 closer to the positioning plate 20, it can simultaneously push multiple locking blocks 50 to simultaneously lock into the recessed cavity 203 of the workpiece 2. The positioning plate 20 and the mounting component 40 are spaced apart along the first direction X, and the first driving mechanism 30 pushes the mounting component 40 closer to or further away from the positioning plate 20 along the first direction X.

[0051] In some embodiments, see Figure 6 There are two locking blocks 50 and four grooves 41. Two of the four grooves 41 are spaced apart along the second direction Y, and the other two grooves 41 are spaced apart along the third direction Z. The second direction Y and the third direction Z intersect.

[0052] In the example shown, the second direction Y and the third direction Z are perpendicular.

[0053] In some embodiments, this application further includes a rotary cylinder, which is disposed on the mounting assembly 40 and is used to drive the mounting assembly 40 to rotate. With this configuration, this application only needs to set two locking blocks 50 to achieve the positioning of four workpieces 2 to be processed. In the first positioning, two workpieces 2 that are spaced apart in the same direction are aligned with the two locking blocks 50. After the first batch of two workpieces 2 to be processed is completed, the rotary cylinder is used to align the other two workpieces 2 to be processed with the two locking blocks 50, and then the positioning processing is performed. At the same time, the first batch of two workpieces 2 to be processed can be taken out, thereby improving the processing efficiency.

[0054] In some embodiments, see Figure 4 The locking block 50 includes an annular seat. When the mounting component 40 is in a fixed position, the outer wall of the annular seat abuts against the inner wall of the recessed cavity 203. When the locking block 50 is locked into the annular seat, the workpiece 2 to be processed can be fixed more firmly and accurately during the processing.

[0055] In some embodiments, see Figure 4The positioning plate 20 is provided with a tool inlet 21 at the position corresponding to the annular seat, so that when the mounting assembly 40 is in a fixed position, the external tool can enter the recessed cavity 203 of the workpiece 2 through the tool inlet 21, thereby realizing the processing of the workpiece 2.

[0056] In some embodiments, see Figure 1 and Figure 5 The mounting assembly 40 includes a mounting plate 42 and at least two mounting seats 43. The at least two mounting seats 43 are adapted to at least two grooves 41. The grooves 41 are provided on the corresponding mounting seats 43. The mounting seats 43 are detachably connected to the mounting plate 42. With this configuration, different types of workpieces 2 can be positioned by changing the mounting seats 43 on the mounting plate 42, adapting to workpieces 2 of different shapes and sizes, thus improving the applicability and versatility of the positioning device 1.

[0057] In some embodiments, the first drive mechanism 30 includes a pneumatic cylinder or a hydraulic cylinder.

[0058] In the example shown, the output shaft of the cylinder or hydraulic cylinder is connected to the mounting plate 42.

[0059] In summary, this application ensures that the workpiece 2 will not move or shift during processing, thereby improving processing accuracy and consistency. Secondly, by engaging the locking block 50 within the recessed cavity 203 of the workpiece 2, the fixation effect of the workpiece 2 is further enhanced, preventing loosening or detachment due to vibration or external force during processing. Furthermore, because the workpiece 2 is more firmly and precisely fixed during processing, the scrap rate caused by movement or positional deviation of the workpiece 2 is reduced, improving product qualification rate and quality.
