Description

Technical Field

[0001] This utility model relates to the field of electronic product surface polishing and grinding technology, and in particular to a slope gravity control mechanism in a grinding equipment. Background Technology

[0002] The final processing step for the surface of electronic product casings is polishing and grinding. This process is carried out using grinding equipment, which typically includes a grinding mechanism and grinding discs integrated into the grinding mechanism. It also has a lead screw mechanism for adjusting the workpiece displacement. A precision divider and a tooling fixture integrated into the precision divider are mounted on the lead screw mechanism. After the workpiece is reliably clamped onto the tooling fixture, the precision divider and tooling fixture are moved by the lead screw mechanism, thereby adjusting the contact between the workpiece and the grinding discs.

[0003] The position of the workpiece relative to the grinding disc is mainly adjusted by a lead screw mechanism. The displacement in the lead screw mechanism is based on the minimum displacement limited by the pitch. A finer pitch cannot meet the stable adjustment under load conditions, while a coarser pitch will cause the workpiece to not be in continuous contact with the grinding disc during the grinding process. Ultimately, this may result in transition marks on the surface of the workpiece after grinding, affecting the surface grinding quality. Summary of the Invention

[0004] (a) Technical issues

[0005] The purpose of this invention is to provide a slope gravity control mechanism for grinding equipment, which solves the problem in the prior art that the lead screw mechanism does not float after adjusting the relative position, and may cause the workpiece to lose contact with the grinding disc during the grinding process.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A slope gravity control mechanism for a grinding device includes a grinding mechanism, a mounting base, and a transverse slide rail mounted on the mounting base. A support seat is mounted on the transverse slide rail, and a screw drive mechanism for driving the support seat to move along the transverse slide rail is provided on the mounting base. An inclined slide table and an inclined slide rail mounted on the inclined slide table are mounted on the support seat. The inclined slide rail is inclined towards the grinding mechanism. A counterweight slide table is mounted on the inclined slide rail. A divider and a fixture mounted on the divider are mounted on the counterweight slide table. The fixture is used to clamp a workpiece. When the counterweight slide table drives the fixture to slide towards the grinding mechanism, the workpiece remains in contact with the grinding disc in the grinding mechanism.

[0009] Preferably, the inclined slide is provided with a first inclined surface, and the counterweight slide is provided with a second inclined surface. The first inclined surface and the second inclined surface are parallel and both are inclined toward the grinding mechanism. The inclination angle of the first inclined surface and the second inclined surface is 10°. A first positioning step is provided at intervals on the first inclined surface, and a second positioning step is provided at intervals on the second inclined surface. The inclined slide rail is installed between the first positioning step and the second positioning step on the corresponding side.

[0010] Preferably, a damping structure is installed on the counterweight slide and / or the inclined slide.

[0011] Preferably, the inclined slide rail includes a first slide rail mounted on a first positioning step and at least two first sliders mounted on a second positioning step, wherein the first sliders slide in cooperation with the first slide rail.

[0012] Preferably, the support base is equipped with a limiting block for limiting the sliding limit position of the counterweight slide.

[0013] Preferably, the inclined slide rail includes a first slide rail mounted on a first positioning step and at least two first sliders mounted on a second positioning step, wherein the first sliders slide in cooperation with the first slide rail.

[0014] Preferably, the transverse slide rail includes a second slide rail spaced apart on the mounting base and a second slider mounted on the support, the second slider being slidably engaged with the second slide rail.

[0015] Preferably, the lead screw drive mechanism includes a drive lead screw rotatably mounted on the mounting base, a first drive motor connected to the drive lead screw, a connecting block mounted on the bearing seat, a lead screw nut mounted on the connecting block, and the lead screw nut threadedly engaging with the drive lead screw.

[0016] Preferably, a support block is mounted on the mounting base, and the second slide rail is mounted on the support block.

[0017] Preferably, the weight of the counterweight slide is greater than 30 kg.

[0018] By adding an inclined slide to the screw drive mechanism and installing a counterweight slide via an inclined slide rail, the divider and tooling are sequentially installed on the counterweight slide. Under the gravity of the counterweight slide, divider, and tooling, the whole will move relative to the inclined slide rail, thereby keeping the workpiece clamped on the tooling in contact with the grinding disc. The reverse pushing force generated during the grinding process also allows the workpiece to float relative to the grinding disc, thus achieving self-correction adjustment of the grinding thickness during the grinding process.

[0019] The lead screw drive mechanism mainly achieves position adjustment over a larger distance. When it finally approaches the smaller gap of the grinding disc, the self-correcting adjustment structure composed of the counterweight slide, tilting slide, and inclined slide ensures that the workpiece continues to contact the grinding area to complete the entire grinding process.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] See Figures 1-5As shown, the embodiment of this utility model proposes a slope gravity control mechanism in a grinding device, integrated into existing grinding equipment. It mainly clamps the workpiece and controls the feeding. The grinding device includes a grinding mechanism 13 and a grinding disc 14 integrated on the grinding mechanism 13. During the grinding process, the workpiece contacts the grinding disc 14 for grinding and polishing. Specifically, it includes a mounting base 1 and a transverse slide rail 2 mounted on the mounting base 1. A support seat 3 is mounted on the transverse slide rail 2. The mounting base 1 is equipped with a screw drive mechanism 4 for driving the support seat 3 to move along the transverse slide rail 2. The screw drive mechanism drives the support seat 3 to move back and forth along the transverse slide rail 2 to adjust the workpiece relative to the grinding mechanism 13. The screw drive mechanism 4 can achieve rapid adjustment, but due to the minimum pitch limitation, it cannot guarantee that the contact depth and position between the workpiece and the grinding disc 14 will be exactly the same after each adjustment. This can easily lead to excessive processing marks during actual grinding.

[0029] To address the issue of inconsistent feed stroke in the lead screw mechanism leading to transitional marks on the workpiece surface during grinding, an inclined slide table 5 and an inclined slide rail 6 are installed on the bearing seat 3. The inclined slide rail 6 is inclined towards the feed direction. A counterweight slide table 7 is installed on the inclined slide rail 6, and a divider 11 and a fixture 8 are installed on the divider 11. The fixture 8 is used to clamp the workpiece. A second drive motor 12 is connected to the divider 11. The divider 11 is high-precision and can rotate at an angle under the drive of the second drive motor 12, thereby driving... The workpiece is angled relative to the grinding disc 14. The counterweight slide 7, the inclined slide rail 6, and the inclined slide 5 form a self-correcting adjustment structure. Under the gravity of the counterweight slide 7, the divider 11, and the tooling 8, the workpiece can slide relative to the inclined slide rail 6 toward the grinding mechanism 13 until it moves to the point where the workpiece and the grinding disc 14 come into contact. The workpiece and the grinding disc 14 can maintain contact throughout the grinding process. At the same time, the angle of the tooling 8 is adjusted by the divider 11, and the workpiece can maintain contact during the angle rotation relative to the grinding disc 14, thus continuously completing the grinding action and effectively avoiding the occurrence of over-grind marks.

[0030] Therefore, after the position adjustment is quickly achieved through the lead screw mechanism, the workpiece and the grinding disc 14 are kept in continuous contact for grinding by the self-weight of the counterweight slide 7, the divider 11 and the tooling 8. This effectively solves the problem of inconsistency in the existing technology that uses only the lead screw mechanism for feeding stroke control.

[0031] Since the divider 11 and tooling 8 both adopt the structure of existing grinding equipment, their weight is fixed. In order to ensure that the counterweight slide 7 and the integrated structure on it can slide smoothly relative to the inclined slide rail 6, the inclination angle of the inclined slide rail 6 is designed to be 10°, and the weight of the counterweight slide 7 is made greater than 30 kg. This allows for adjustment of the relative sliding speed and the force applied when in contact with the grinding disc 14. During manufacturing, the sliding speed and the force applied to the grinding disc 14 can be adjusted by changing the installation angle of the inclined slide rail 6 and the weight of the counterweight slide 7.

[0032] Alternatively, a more general approach can be considered, such as installing a damping structure on the counterweight slide 7 and / or the inclined slide 5. The damping structure applies relative sliding friction, for example, by using a floating damping block or a spring-connected damping block. It applies a certain sliding friction to the counterweight slide 7 relative to the inclined slide 5 to maintain sliding stability and control the sliding speed and the force applied to the grinding plate 14. Specifically, the damping structure can be set on either the counterweight slide 7 or the inclined slide 5, with the side that generates the sliding friction abutting against the other side.

[0033] Specifically, in order to achieve proper positioning and installation of the inclined slide rail 6, ensure smooth sliding, and avoid sliding resistance caused by unbalanced installation of the inclined slide rail 6, such as... Figure 1 , Figure 2 As shown, a first inclined surface 51 is provided on the inclined slide table 5, and a second inclined surface 71 is provided on the counterweight slide table 7. The first inclined surface 51 and the second inclined surface 71 are parallel, and the inclination angles of the first inclined surface 51 and the second inclined surface 71 are both 10°, thereby realizing the installation angle of the inclined slide rail 6. At the same time, a first positioning step 52 is provided at intervals on the first inclined surface 51, and a second positioning step 72 is provided at intervals on the second inclined surface 71. The inclined slide rail 6 is installed between the first positioning step 52 and the second positioning step 72 on the corresponding side. By matching and processing the first positioning step 52 and the second positioning step 72, the smooth sliding of the inclined slide rail 6 can be guaranteed after installation.

[0034] The inclined slide rail 6 includes a first slide rail 61 installed on the first positioning step 52 and at least two first sliders 62 installed on the second positioning step 72. The first sliders 62 are slidably engaged with the first slide rail 61. The inclined slide rail 6 is a split structure. After being installed on the first positioning step 52 and the second positioning step 72 respectively, it can achieve reference positioning and ensure smooth sliding after sliding engagement.

[0035] In order to limit the extreme position of the counterweight slider relative to the inclined slide table 5 and avoid the risk of the counterweight slide table 7 sliding out, it is necessary to limit the extreme position. Therefore, a limiting block 9 is installed on the bearing seat 3 to limit the extreme position of the sliding of the counterweight slide table 7.

[0036] Specifically, the support seat 3 has a large weight after the various components are integrated and installed, and it needs to be able to slide stably. It also needs to be able to connect the support seat 3 and the mounting base 1 through the transverse slide rail 2. The transverse slide rail 2 includes a second slide rail 21 that is spaced on the mounting base 1 and a second slider 22 that is installed on the support seat 3. The second slider 22 slides in cooperation with the second slide rail 21.

[0037] The relative sliding of the bearing seat 3 is driven by the lead screw drive mechanism 4, wherein, for example... Figure 3 , Figure 4 As shown, the lead screw drive mechanism 4 includes a drive screw 41 rotatably mounted on the mounting base 1, a first drive motor 42 connected to the drive screw 41, a connecting block 43 mounted on the bearing seat 3, and a lead screw nut 44 mounted on the connecting block 43. The lead screw nut 44 is threadedly engaged with the drive screw 41. By controlling the forward or reverse rotation of the first drive motor 42, the drive screw 41 and the lead screw nut are threadedly (helically) engaged, and the bearing seat 3 is restricted to slide on the transverse slide rail 2, thereby enabling the bearing seat 3 to move back and forth relative to the transverse slide rail 2 to adjust its relative position.

[0038] Meanwhile, in order to facilitate the formation of an installation space between the bearing seat 3 and the mounting base 1 to accommodate the entire lead screw drive mechanism 4, a support block 10 is installed on the mounting base 1, and the second slide rail 21 is installed on the support block 10. The support block 10 is used to raise the overall height of the bearing seat 3 to form the installation space.

[0039] Specifically, in order to achieve relative sliding balance and stability, the number of inclined slide rails 6 and transverse slide rails 2 is at least two.
