Description

Technical Field

[0001] The utility model relates to the field of machining equipment, in particular to an automatic polishing device for the end face of a lock shell. Background Art

[0002] Smart door locks are different from traditional mechanical locks, offering more intelligent features in terms of user identification, security, and management. They are also the locking components of access control systems. After the mechanical components of a smart lock are die-cast, they are sent to a polishing workshop for polishing. The outer shell is primarily polished, which involves cleaning and grinding the surface. The polishing effect directly affects the aesthetics and durability of the finished smart lock.

[0003] The lock housing of existing smart door locks is made of die-cast aluminum alloy, which has a high surface roughness and requires grinding and polishing. The current processing method is for workers to hold the housing and polish it on a dedicated sanding machine. This grinding and polishing method is inefficient, and the dust generated during the polishing process is scattered everywhere, which can easily affect the health of the operator.

[0007] Furthermore, a servo motor for driving the turntable is provided on the frame, and the rotation angle of the turntable is consistent with the distribution angle of two adjacent lock housing positioning seats.

[0008] Furthermore, the sanding belt machine has a sanding belt arranged in an inverted triangle shape, and the pre-pressing device is arranged in front and behind the movement of the sanding belt.

[0009] Furthermore, the pre-pressing device includes a roller, a bracket, and an elastic support. The bracket is installed on the housing of the sanding machine, and the elastic support is arranged between the end of the roller and the bracket.

[0010] Furthermore, an ash collecting trough is provided on the frame, and the ash collecting trough is provided below the turntable.

[0011] The beneficial effects of the utility model include: realizing automatic grinding and polishing of the end face of the lock case, significantly improving the processing efficiency of grinding the end face of the lock case, ensuring the safety of the operator, and avoiding the scattering of polishing dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0013] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0014] A kind of Figure 1 The automatic polishing device for the end face of a lock case shown includes a frame 1, on which a horizontally arranged turntable 2 and a vertically arranged cross-moving mechanism 3 are provided. A plurality of lock case positioning seats 4 are evenly distributed in a ring shape on the top surface of the turntable 2, and the positioning seats 4 have a plurality of positioning grooves 6 arranged in parallel, and the positioning grooves 6 are used to position the lock case in the positioning grooves 6. A sanding machine 5 is provided on the cross-moving mechanism 3, and the sanding machine 5 can move laterally and longitudinally. The sanding machine 5 can be moved to the top of the turntable 2 and face a lock case positioning seat 4, so that the sanding belt on the sanding machine 5 grinds the end face of the lock case positioning seat 4. A pre-pressing device is provided at the bottom of the sanding machine 5, which is used to press the front and rear sides of the polishing part of the lock case during polishing.

[0015] A servo motor driving the turntable 2 is provided on the frame 1. The rotation angle of the turntable 2 is consistent with the distribution angle of two adjacent lock case positioning seats 4. This structure enables the turntable 2 to switch a lock case positioning seat 4 to face the sanding machine 5 each time it rotates, thereby achieving the purpose of automatic part replacement.

[0016] The belt sander 5 has a sanding belt 6 arranged in an inverted triangle shape. A pre-compression device is provided in front and behind the movement of the sanding belt 6. The pre-compression device includes a roller 7, a bracket 8, and an elastic support 9. The bracket 8 is mounted on the housing of the belt sander 5, and the elastic support 9 is provided between the end of the roller 7 and the bracket 8. When the belt sander 5 moves downward, the roller 7 contacts the lock case on the lock case positioning seat 4 in advance, and when the sanding belt contacts the end face of the lock case, the elastic support 9 elastically compresses the lock case to prevent the lock case from detaching from the lock case positioning seat 4 during sanding. The roller 7 can rotate, and when the belt sander 5 moves laterally, the roller 7 and the lock case roll and rub against each other to avoid scratching the end face of the lock case being polished. The width of the sanding belt 11 should be greater than the total width of the multiple positioning slots 6 arranged in parallel, so as to ensure that multiple lock cases can be polished at the same time.

[0017] An ash collecting trough 10 is provided on the frame 1 and is provided below the turntable 2. This structure allows the dust generated during the grinding and polishing process to fall into the ash collecting trough 10 to avoid scattering around and affecting the processing environment.

[0018] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
