Description

Technical Field

[0001] The utility model particularly relates to a positioning device for profile processing. Background Art

[0002] During the processing of profiles, operations such as grinding are required. In this process, a positioning device is needed to prevent the profile from shifting during processing. The existing positioning device includes a base, and a recessed groove is provided on the base. The groove is used to position the profile, and then a grinding tool is used to grind the profile. The debris formed by grinding will accumulate in the groove, and after each grinding, the staff needs to clean it, which is very cumbersome. Moreover, the width of the groove is fixed, so when the width of the profile changes, it is difficult for the groove to position the profile, and its use is very limited. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a positioning device for profile processing.

[0004] To solve the above-mentioned existing technical problems, the utility model adopts the following technical solutions:

[0005] A positioning device for profile processing includes a base. The base is provided with a protruding positioning platform. Avoidance grooves for the side parts of the profile to extend into are respectively arranged on both sides of the positioning platform. A stop member is arranged on the positioning platform along the width direction, and the upper end of the stop member extends into the profile. A pressing plate is arranged at the end of the positioning platform, and an adjusting structure is arranged between the pressing plate and the positioning platform. When the profile is installed on the positioning platform, the pressing plate presses the profile under the action of the adjusting structure.

[0006] Preferably, the adjusting structure includes an installation groove arranged on the positioning platform and an elastic member arranged in the installation groove. The upper end of the elastic member is connected with a pull rod, and the pull rod is connected to the pressing plate.

[0007] Preferably, the elastic member is a spring.

[0008] Preferably, the avoidance groove is an L-shaped structure.

[0009] Preferably, positioning grooves are symmetrically arranged along the length direction in the middle of the positioning platform. When the profile is installed on the positioning platform, the clamping part of the profile extends into the positioning grooves.

[0010] Preferably, an opening for the pressing plate to press is provided on the profile.

[0011] The beneficial effects of the utility model are:

[0012] During the grinding process of the positioning device of the present application, since the positioning table is convex outward, the debris generated during the grinding process will fall on the periphery of the positioning device, and a certain number of profiles can be ground before cleaning; the positioning device of the present application blocks the clamping part of the profile through the stopper and presses the profile through the pressing plate, so the phenomenon of profile displacement during the processing can be effectively prevented.

[0024] A positioning device for profile processing, comprising a base 1, the base 1 is provided with a positioning table 2 protruding outwards, both sides of the positioning table 2 are respectively provided with avoidance grooves 3 for the side parts of the profile 20 to extend into, the positioning table 2 is provided with a stop member 4 in the width direction, the upper end of the stop member 4 extends into the profile 20, the end of the positioning table 2 is provided with a pressing plate 5, and an adjusting structure is arranged between the pressing plate 5 and the positioning table 2. When the profile 20 is installed on the positioning table 2, the pressing plate 5 presses the profile 20 under the action of the adjusting structure.

[0025] Furthermore, the adjusting structure includes an installation groove 61 arranged on the positioning table 2 and an elastic member 62 arranged in the installation groove 61. The upper end of the elastic member 62 is connected with a pull rod 63, and the pull rod 63 is connected to the pressing plate 5.

[0026] Furthermore, the elastic member 62 is a spring.

[0027] Furthermore, the avoidance groove 3 is an L-shaped structure.

[0028] Furthermore, positioning grooves 7 are symmetrically arranged along the length direction in the middle of the positioning table 2. When the profile 20 is installed on the positioning table 2, the clamping portions 21 of the profile 20 extend into the positioning grooves 7.

[0029] Furthermore, an opening 51 for the pressing plate 5 to press is formed on the profile 20.

[0030] The working principle of the present utility model is:

[0031] As Figure 1 shown, this is the state where the profile 20 is installed on the positioning device. As can be Figure 1 seen, both side parts of the profile 20 extend into the avoidance grooves 3 respectively, and the clamping portions 21 on the profile 20 are inserted into the positioning grooves 7. As Figure 3As shown, at this time, the upper end of the stopper 4 is located at one end of the clamping portion 21 of the profile 20 away from the pressing plate 5, and the pressing plate 5 presses the profile 20 under the action of the adjusting structure; Figure 1 The direction of the arrow in Figure 1 is the direction of grinding. When the operator grinds with force in the right direction, at this time, due to the pressing action of the pressing plate 5, although the profile 20 has a tendency to move to the right, due to the pressing action of the pressing plate 5, the profile 20 will not move relatively. When the operator grinds the profile 20 with force in the left direction, at this time, the stopper 4 on the positioning table 2 extends into the profile 20 and is located on one side of the clamping portion 21, that is to say, at this time, the profile 20 has a tendency to move to the left, but the stopper 4 has a blocking effect on the clamping portion 21 of the profile 20, so the profile 20 can be prevented from moving to the left, effectively avoiding the relative movement between the profile 20 and the positioning device; during the grinding process, since the positioning table 2 is convexly arranged outward, the debris generated during the grinding process will fall on the periphery of the positioning device, and a certain number of profiles 20 can be ground before cleaning; the positioning device of the present application blocks the clamping portion of the profile through the stopper, and presses the profile through the pressing plate, so the phenomenon of displacement of the profile during the processing can be effectively prevented. In addition, when the width of the profile 20 of the present application increases, the positioning device of the present application can still be applied, because the positioning of the present application mainly relies on the stopper 4 to block the clamping portion 21 of the profile 20 and the pressing plate 5 to press the profile 20, so even if the width of the profile 20 changes, the positioning of the profile 20 can still be applied.

[0032] On the basis of the above basic solution, considering that different types of profiles 20 have different thicknesses, an adjusting structure is provided between the pressing plate 5 and the positioning table 2 in the present application. The adjusting structure can refer to Figure 5 the spring and pull rod 63 structure shown in Figure 5 . Pull the pressing plate 5 to move it upward. The pressing plate 5 will pull the pull rod 63 upward. At this time, the spring is in a stretched state, and then release the pressing plate 5. The spring restores its deformation and drives the pressing plate 5 to press on the profile 20.

[0033] As Embodiment 1, as shown in Figure 3 Figure 3 , a clamping portion 21 is integrally formed at the lower end of the profile 20. The stopper 4 can be set to be detachably connected to the positioning table 2. When the length of the clamping portion 21 of the profile 20 changes, the stopper 4 can move and be positioned at the corresponding position on the positioning table 2. The stopper 4 can be connected to the positioning table 2 by bolts. An opening 51 for the pressing plate 5 to be embedded is provided on the upper end surface of this profile 20. With this setting, the positioning effect on the profile 20 is enhanced.

[0034] On the basis of the above technical solution, the avoidance groove 3 can be designed into an L-shaped structure.

[0035] Although the present utility model has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made to the present utility model without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of this disclosure is only for explanation and not for limiting the present utility model, but the scope of protection is defined by the content of the claims.
